Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method and a device for determining existence of an equipment identification code. The details will be described below separately.
The first embodiment,
The embodiment will be described from the perspective of a server, and the apparatus for determining the existence of the device identification code may be specifically integrated in a device such as a terminal.
Referring to fig. 1, the present embodiment provides a method for determining the existence of an equipment identity, and the specific process may be as follows:
101. and receiving a search request sent by a terminal, wherein the search request carries the equipment identification code of the terminal.
Specifically, when the terminal performs data interaction with the server, the terminal sends a service request to the server, where the service request includes the search request, that is, includes the device identification code of the terminal, and it needs to be noted that the device identification code has uniqueness, such as an IMEI number; for example, when the terminal searches for a keyword through a browser, a service request carrying the terminal device identification code is sent to the server, and the server receives and processes the request.
102. And dividing the equipment identification code according to a preset division rule to obtain a first sub-equipment identification code and a second sub-equipment identification code, wherein the first sub-equipment identification code and the second sub-equipment identification code are combined to form the equipment identification code.
Specifically, the device identification code includes a series of character strings, and the server obtains the device identification code of the terminal according to the search request, and divides the device identification code according to a preset division rule to obtain a first sub-device identification code and a second sub-device identification code, where the first sub-device identification code and the second sub-device identification code are combined to form the device identification code, that is, the first sub-device identification code includes a first M-bit string of the device identification code, and the second sub-device identification code includes a second N-bit string of the device identification code. M, N are all positive integers, and the sum of M and N is the total number of characters in the terminal equipment identification code string.
In a specific implementation process, the preset division rule may divide the device identification code into two parts, for example, divide an IMEI number of the terminal, where the IMEI number includes 15 digital characters, and divide the IMEI number once from the 8 th character to the 9 th character, to obtain a first 8-digit character as a first sub-device identification code of the terminal, and a second 7-digit character as a second sub-device identification code of the terminal.
Preferably, before the device identification code is divided, the server may obtain feature information of the device identification code, and determine whether the feature information matches preset feature information, if yes, perform an operation of dividing the device identification code, and if not, not perform the operation of dividing the device identification code. For example, if the preset feature information is that the device identification code needs to be a 15-bit numeric character string, when the device identification code carried in the search request contains other characters or the number of characters is not 15, the server determines that the device identification code does not conform to the preset feature information, and therefore the operation of dividing the device identification code is not performed.
103. And acquiring an equipment identification code set corresponding to the first sub-equipment identification code, wherein the equipment identification code set comprises at least one second preset sub-equipment identification code.
In this embodiment of the present invention, before receiving the search request sent by the terminal, the device identifier of the terminal needs to be processed in advance, that is, before "receiving the search request sent by the terminal, where the search request carries the device identifier of the terminal" in step 101, the method may further include:
acquiring a plurality of preset equipment identification codes;
dividing the preset equipment identification code to obtain a first preset sub-equipment identification code and a second preset sub-equipment identification code, wherein the first preset sub-equipment identification code and the second preset sub-equipment identification code are combined to form the preset equipment identification code;
and setting the corresponding relation between the first preset sub-equipment identification code and the second preset sub-equipment identification code.
Specifically, when the server creates a search rule of the device identification codes, the server may obtain the device identification codes of the plurality of terminal devices, that is, the preset device identification codes, divide the preset device identification codes to obtain the first preset sub-device identification code and the second preset sub-device identification code, and then set the corresponding relationship between the first preset sub-device identification code and the second preset sub-device identification code; the rule for dividing the preset device identification code is the same as the rule for dividing the device identification code of the terminal by the server in the step 102.
The step of "setting the corresponding relationship between the first preset sub-device identification code and the second preset sub-device identification code" may be to filter out the repeated first preset sub-device identification code after dividing the preset device identification code, and then establish the corresponding relationship between the second preset sub-device identification code and the first preset sub-device identification code according to the status code before the preset device identification code is not divided, so as to obtain the device identification code set corresponding to the first preset sub-device identification code.
For example, if the device a1 identification code is a + b and the device a2 identification code is a + c, where a, b, and c are numeric character strings, the device a1 identification code is divided to obtain a first sub-device a1 identification code a and a second sub-device a1 identification code b of the device a1 identification code, and the device a2 identification code is divided to obtain a first sub-device a2 identification code a and a second sub-device a2 identification code c of the device a2 identification code; since the first sub-device id of the device a1 and the first sub-device a2 id of the device a2 are both a, the first sub-device a2 id a and the second sub-device a2 id c are associated with a to obtain a device id set corresponding to the first preset sub-device id. I.e. the set of device identifiers of the first device identifier a is b, c.
Preferably, the step of setting the corresponding relationship between the first preset sub-device identification code and the second preset sub-device identification code may specifically include:
acquiring a file corresponding to the first preset sub-device identification code;
and taking the second preset sub-device identification code as the content of the file.
In a specific implementation process, a file may be created, the first preset sub-device identification code is used as a name of the file, the second preset sub-device identification code is used as content of the file, and a corresponding relationship between the first preset sub-device identification code and the second preset sub-device identification code is set.
Preferably, the step of "acquiring the device identification code set corresponding to the first sub-device identification code" may specifically include:
judging whether a first preset sub-equipment identification code which is the same as the first sub-equipment identification code exists or not;
if so, acquiring a device identification code set corresponding to the first sub-device identification code according to the corresponding relation between the first preset sub-device identification code and the second preset sub-device identification code.
Specifically, the server judges whether a first preset sub-device identification code identical to the first sub-device identification code exists in the database, if so, the first preset sub-device identification code is obtained, and then all second preset sub-device identification codes corresponding to the first preset sub-device identification code in the database are obtained according to the first preset sub-device identification code, so that a device identification code set corresponding to the first sub-device identification code is obtained.
The step of obtaining the device identification code set corresponding to the first sub-device identification code according to the corresponding relationship between the first preset sub-device identification code and the second preset sub-device identification code may specifically include:
acquiring a file corresponding to the first sub-device identification code;
and extracting the content of the file to obtain a device identification code set corresponding to the first sub-device identification code.
104. And searching a second preset sub-device identification code which is the same as the second sub-device identification code in the device identification code set to obtain a searching result.
Specifically, the server searches for a second preset sub-device identification code which is the same as the second sub-device identification code from the device identification code set corresponding to the acquired first sub-device identification code, so as to obtain a search result.
105. And when the search result is a second preset sub-equipment identification code with the same second sub-equipment identification code, determining that the equipment identification code exists according to the search result.
Specifically, the server determines whether the device identification code exists according to the search result, and if the device identification code exists, the server acquires corresponding search content according to the search request and feeds the search content back to the terminal.
As can be seen from the above, an embodiment of the present invention provides a method for determining the existence of an equipment identity, where a search request sent by a receiving terminal is adopted, where the search request carries an equipment identity of the receiving terminal, and then the equipment identity is divided according to a preset division rule to obtain a first sub-equipment identity and a second sub-equipment identity, and obtain an equipment identity set corresponding to the first sub-equipment identity, where the equipment identity set includes at least one second preset sub-equipment identity, and a preset sub-equipment identity identical to the second sub-equipment identity is searched in the equipment identity set to obtain a search result, and when the search result is that the second preset sub-equipment identity identical to the second sub-equipment identity is searched, the equipment identity is determined to exist; according to the scheme, the equipment identification code of the terminal can be divided into two sub-equipment identification codes, whether the equipment identification code exists is determined by searching the sub-equipment identification code, and compared with the prior art, the memory consumption for searching the equipment identification code can be reduced, so that the memory occupancy rate is reduced.
Example II,
The present embodiment further describes the method for determining the presence of the device identification code according to the present invention on the basis of the first embodiment. As the server needs to cache the file state in the search process, the cache is easily removed due to too many files, and as can be seen from the first embodiment, the method can only take effect for the existing device identification code, and in order to improve the execution efficiency and the search quality of the server, the method of this embodiment limits the step of "obtaining the file corresponding to the first preset sub-device identification code" when creating the search rule, that is, the step of "obtaining the file corresponding to the first preset sub-device identification code" may specifically include:
judging whether a file path corresponding to the first preset sub-equipment identification code exists or not;
if so, acquiring a file corresponding to the file path;
if not, generating a corresponding file path according to the first preset sub-equipment identification code, and creating a file corresponding to the file path.
Specifically, when a cache file of a file path corresponding to the first preset sub-device exists, the corresponding file is acquired, otherwise, the corresponding file path is generated according to the identification code of the first preset sub-device, and the file corresponding to the file path is created.
Correspondingly, the step of acquiring the file corresponding to the first sub-device identification code may specifically include:
acquiring a file path corresponding to the first sub-device identification code;
judging whether a file path corresponding to the first sub-equipment identification code exists or not;
and if so, acquiring the file corresponding to the file path.
Preferably, in order to reduce the number of files in a single directory, in the embodiment of the present invention, when creating the search rule of the server, the first preset sub-device identification code of the preset device identification code may be divided to create a secondary folder, so as to reduce fragmented files; for example, the IMEI number of the terminal device is formed by 15 digits of arabic numerals, the first 6 digits of the IMEI number represent the model of the terminal, and the 7-8 digits represent the production address, so that the first 6 digits of the IMEI number can be used as the folder name to create a secondary folder, and the 7-8 digits can be used as the file name of the file in the folder, so as to avoid excessive fragmented files. By analogy, the 1 st to 6 th positions of the folder can be divided to create a second-level folder.
Preferably, when creating the search rule of the server, in order to be able to quickly locate the second preset sub-device identification code in the file corresponding to the first preset sub-device identification code, when a series of second preset sub-device identification codes are used as the content of the file, the second preset sub-device identification codes may be preprocessed, that is, between the step of "using the second preset identification code as the content of the file" and the step of "receiving the search request sent by the terminal", the method may further include:
and sequencing the second preset sub-equipment identification codes in the file according to the number size corresponding to the second preset sub-equipment identification codes.
Specifically, the device identification code includes a numeric character, the second preset sub-device identification code may be added to the end of the file content, and the second preset sub-device identification code is sorted from high to low according to the corresponding numeric size and from small to large or from large to small, so that the server may quickly find the target device identification code in the file by using a binary search method.
For example, the device identifiers are 1234567890, 1234576890, 1234567980, and 1234567089, the second-level folder may be created by using bits 1 to 5 of the device identifiers as the folder name, bits 6 to 7 are used as the file name, and bits 8 to 9 are added to the end of the file content, so as to obtain file paths 12345/67 and 12345/76, where the file content corresponding to the file path 12345/67 includes 890, 980, and 089, the child device identifiers in the file content are sorted from small to large, so as to obtain 089, 890, and 980, and so on, when the data size is large, the server may quickly locate the device identifier by using a binary search method according to the search rule.
As can be seen from the above, an embodiment of the present invention provides a method for determining the existence of an equipment identity, where a search request sent by a receiving terminal is adopted, where the search request carries an equipment identity of the receiving terminal, and then the equipment identity is divided according to a preset division rule to obtain a first sub-equipment identity and a second sub-equipment identity, and an equipment identity set corresponding to the first sub-equipment identity is obtained, where the equipment identity set includes at least one second preset sub-equipment identity, and a preset sub-equipment identity identical to the second sub-equipment identity is searched in the equipment identity set to obtain a search result, and when the second preset sub-equipment identity identical to the second sub-equipment identity is searched, the equipment identity is determined to exist; according to the scheme, when the search rule is established, the secondary folder is added, so that excessive and fragmented files are avoided, the sub-equipment identification codes in the file corresponding to the first equipment identification code are sequenced, and the search speed is accelerated; compared with the prior art, the method can reduce the memory consumption of searching the equipment identification code, thereby reducing the memory occupancy rate.

The method for determining the presence of a device identification code according to the embodiments one and two will be described in further detail below by way of example.
In this embodiment, the apparatus for determining the existence of the device identification code is specifically integrated in the smart phone, and the device identification code is, for example, the IMEI number of the smart phone, and relevant description is performed.
It should be noted that, in the embodiment of the present invention, a search rule of the server needs to be created in advance; specifically, the IMEI numbers of a plurality of smart phones are acquired and divided, in this embodiment, it is preferable to divide 15 digits of the IMEI numbers into three parts, with digits 1 to 6 as one unit, digits 7 to 8 as one unit, and digits 9 to 15 as one unit; for example, if the IMEI number is 864182020468931, using the 1 st to 6 th digits as a folder name, creating a folder, creating a file in the folder, for example, a txt text document, using the 7 th to 8 th digits of the IMEI number as the file name, obtaining a file path,/864182/02. txt, adding the 9 th to 15 th digits of the IMEI number as a unit to the end of the content of the file, and sorting the file according to a book order of the digit size from small to large; for example, when the content of the document contains the 9 th to 15 th digits of a plurality of IMEI numbers, if the sequence is as follows: 341526068931151242646842162123515, then the sequence is: 04689311512426212351534153264684216.
as shown in fig. 2, a specific process of determining the existence of the device identification code may be as follows:

Specifically, there are various ways for the smartphone to initiate a search request to the server, for example, the smartphone may perform entry search through a browser, and at this time, a service request including a search request of the IMEI number of the smartphone is initiated to the server. The server divides the IMEI number according to the above-created server division rule, for example, the IMEI number is 864182020468931, and after the division, the first sub-device identifier is 86418202, and the second sub-device identifier is 0468931.
202. The server divides the first sub-device identification code to obtain a first sub-device identification code a1 and a first sub-device identification code a 2.
Specifically, the server divides the first sub-device id according to the created server search rule, and obtains 864182 as the first sub-device id a1 and 02 as the first sub-device id a 2.
203. And acquiring a first device identification code set corresponding to the first sub-device identification code a1, wherein the device identification code set comprises at least one first preset sub-device identification code a 2.
Specifically, the server determines whether there is a folder named by the first child device identifier a1, for example IIMEI No. 864182020468931, that is, finds a folder with a folder name of 864182. If yes, the folder corresponding to the first child device identification code a1 is obtained.
204. The first predetermined kid device id a2 that is the same as the first kid device id a2 is found in the first set of device ids.
Specifically, the server searches the first device id set, i.e. the folder in step 203, for the file named by the first sub-device id a2, e.g. IIMEI No. 864182020468931, i.e. for the file with the file name of 02.
205. And determining whether the first preset sub-device identification code a2 exists according to the search result, if so, executing step 206, and if not, executing step 210.
206. And acquiring a second device identification code set corresponding to the first preset sub-device identification code a2, wherein the device identification code set comprises at least one second preset sub-device identification code.
Specifically, taking IIMEI number 864182020468931 as an example, all the second preset child device identification codes are obtained from the file with 02 as the file name.
207. And searching a second preset sub-device identification code which is the same as the second sub-device identification code in the second device identification code set.
Specifically, taking IIMEI No. 864182020468931 as an example, the file content 0468931 is searched for in the second preset sub-device identification code in the file with 02 as the file name.
208. It is determined whether the second predetermined sub-device identification code is found, if yes, step 209 is executed, and if not, step 210 is executed.
209. The server determines that the IMEI number exists.
Specifically, if the server finds a second preset sub-device identification code that is the same as the second sub-device identification code, it determines that the IMEI number exists.
210. And the server feeds back the information of the search failure to the smart phone.
Specifically, if the server does not search the first preset sub-device identification code a2 which is the same as the first sub-device identification code a2 in the first device identification code set, or the server does not search the second preset sub-device identification code which is the same as the second sub-device identification code, the server feeds back the information of the search failure to the smartphone, and displays the information on the display screen of the smartphone.
As can be seen from the above, an embodiment of the present invention provides a method for determining the existence of an equipment identity, where a search request sent by a receiving terminal is adopted, where the search request carries an equipment identity of the receiving terminal, and then the equipment identity is divided according to a preset division rule to obtain a first sub-equipment identity and a second sub-equipment identity, and an equipment identity set corresponding to the first sub-equipment identity is obtained, where the equipment identity set includes at least one second preset sub-equipment identity, and a preset sub-equipment identity identical to the second sub-equipment identity is searched in the equipment identity set to obtain a search result, and the equipment identity is determined to exist according to the search result; according to the scheme, the equipment identification code of the terminal can be divided into two sub-equipment identification codes, whether the equipment identification code exists is determined by searching the sub-equipment identification code, and compared with the prior art, the memory consumption for searching the equipment identification code can be reduced, so that the memory occupancy rate is reduced.
