As used in the specification and this embodiment of the invention, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of a file format conversion method according to an embodiment of the present invention. Fig. 2 is a schematic view of a usage scenario of the file format conversion method in the embodiment of the present invention. The file format conversion method is applied to a mail server, and the mail server can analyze the historical data of the format types of the existing attached files opened by a receiver, so that the formats of the attached files expected to be received by the receiver are converted, corresponding conversion can be effectively carried out according to the requirements of users, and the format conversion efficiency and the use experience degree of the attached files are improved. As shown in fig. 1, the steps of the method include steps S101 to S105.
S101, if a mail sending request is received, determining corresponding mail transmission parameters according to the mail sending request, wherein the mail transmission parameters comprise the initial format of an attachment file.
In this embodiment, if the mail server receives a mail sending request, that is, during the sending process of the mail, and the mail has not yet reached the mailbox of the recipient, the mail delivery parameter corresponding to the mail being sent may be obtained. The mail delivery parameters may include the user name of the recipient and the initial format of the attached file included in the mail, i.e. the initial format type of the attached file, and the attached file in the mail is generally associated with the user name of the recipient. The user name of the receiver can be the mailbox address of the receiver or other names of the receiver.
Further, as shown in fig. 3, the step S101 includes steps S201 to S203.
S201, if a mail sending request is received, determining a user name of a receiver and mail content associated with the user name according to the mail sending request.
In this embodiment, if the mail server receives the mail transmission request, it indicates that the sender has submitted the mail transmission request at this time to transmit the mail content designated by the sender. The mail content is correspondingly associated with the user name of the recipient, and in general, the mail content may include a mail body or an attachment file uploaded by the sender.
S202, judging whether the mail content comprises an attachment file.
In this embodiment, the mail server is required to determine whether the mail content includes an attachment file, and if the mail content does not include the attachment file, the mail server may receive the mail sending request again to perform the determination, and simultaneously, correspondingly transmit the current mail to the recipient.
S203, if the mail content comprises the attachment file, acquiring the attribute information of the attachment file to determine the initial format of the attachment file.
In this embodiment, if the mail server determines that the mail content includes an attachment file, the initial format of the attachment file may be determined according to the attribute information of the attachment file. For example, when the attachment file is in a Word format, the initial format can be determined to be in the Word format according to the attribute information of the attachment file.
S102, determining the target format of the attachment file according to the access record in the target database, wherein the data in the target database is used for describing the corresponding relation between the attachment file and the target format.
In this embodiment, the target database may include several pre-stored access records, and each access record may include a user name of the visitor, a format type of the accessed attachment file, and a corresponding access time. When a receiver is taken as an accessor, and each time the existing attached file associated with the receiver is accessed and opened, the user name of the accessor, the format type of the accessed attached file and the accessed time corresponding to the accessed attached file are taken as an access record to be stored in a target database, so that a mail server can analyze the format type with the most accessed times, the format type with the most accessed times is the target format of the attached file, and the attached file is the attached file associated with the user name of the receiver.
Further, as shown in fig. 4, the step S102 includes steps S301 to S304.
S301, obtaining an access record corresponding to the user name of the visitor, which is the same as the user name of the recipient, from a target database as a first data set, wherein data in the target database is used for describing the corresponding relationship between the attachment file and the target format.
In this embodiment, the target database includes a plurality of access records, each access record includes a username of an accessor, and according to the username of the accessor, the mail server may screen out an accessor username that is the same as the username of a recipient, so as to correspondingly determine the access record corresponding to the accessor username, and in order to determine the format type of an accessed attachment file associated with the same username, it is necessary to count all the determined access records and use the counted access records as the first data set.
S302, obtaining an access record with the access time within a preset time range from the first data set as a second data set.
In this embodiment, in order to more accurately determine the expected format type of the attached file received by the recipient, the mail server may select, as the second data set, an access record whose access time is within a preset time range, so as to avoid that the access record with too long time interval affects the determination of the expected format type of the recipient.
S303, counting the format types of the attachment files corresponding to the access records in the second data set to determine the format type with the maximum number of the access records.
In this embodiment, the access records in the second data set are access records of the recipient within a preset time range, and at this time, the mail server may count all format types of the accessed attachment files opened by the visitor with the same user name as the user name of the recipient, and determine the format type with the largest number of access records of the recipient.
S304, the determined format type is used as the target format of the attachment file.
In this embodiment, the determined format type is the format type with the largest number of accesses by the recipient within the preset time range, so the mail server may determine that the format type is the format type expected by the recipient, and needs to use the format as the target format of the attachment file included in the sent mail.
As an optional embodiment, before the step S304, the method may further include:
s304a, determining whether the number of access records corresponding to the determined format type is greater than a preset threshold.
In this embodiment, in order to improve the accuracy of predicting the expected attachment type of the recipient, the mail server may further determine the number of access records corresponding to the determined format type.
If the number of access records corresponding to the determined format type is greater than the preset threshold, step S304 is executed, that is, the determined format type is used as the target format of the attachment file.
For example, the same recipient accesses the attachment file in the existing email 20 times within a week, wherein the access to the attachment file in the Word format is 10 times, the access to the attachment file in the PDF format is 7 times, and the access to the file in the DWG format is 3 times, and in addition, if the preset threshold value at this time is 11 times, the format of the attachment file desired by the user cannot be determined, and the format of the attachment file in the email to be sent is kept unchanged at this time; if the preset threshold value at this time is 9 times, the Word format at this time is the format of the attachment file expected by the recipient, that is, the Word format is determined as the target format of the attachment file associated with the user name of the recipient.
As a further optional step, the step S102 further includes:
step S305, if the number of access records corresponding to the determined format type is not greater than the preset threshold, taking the initial format of the attachment file as the target format.
In this embodiment, if the number of access records corresponding to the determined format type is not greater than the preset threshold, it indicates that the determined format type is not the attachment type expected by the recipient, and at this time, the mail server does not convert the format type of the attachment file, that is, keeps the initial format of the attachment file unchanged, and takes the initial format as the target format of the attachment file.
S103, judging whether the initial format of the attachment file is the same as the target format.
In this embodiment, the mail server needs to determine whether the initial format of the attachment file included in the mail being sent is the same as the target format, and at this time, it may determine whether the initial format of the attachment file is the format expected by the recipient. If the attachment file is identical, the original format of the attachment file does not need to be converted, and the sent mail can be made to complete the entire sending.
S104, if the initial format of the attachment file is different from the target format, converting the attachment file from the initial format to the target format to obtain the target attachment.
In this embodiment, if the initial format of the attachment file is different from the target format, it indicates that the format type of the attachment file at this time is not the format type expected by the recipient, and the mail server is required to convert the format type of the attachment file from the initial format to the target format, so as to obtain the finally required target attachment.
And S105, sending the target attachment as a mail attachment.
In this embodiment, after the format of the attachment file is converted, the target attachment can be obtained, and the target attachment is sent as an attachment in the mail, where the format of the attachment file in the mail received by the recipient is the target format, that is, the format type expected by the recipient.
In summary, the embodiment can not only improve the work efficiency of mail transmission, but also improve the use experience of the user, that is, the format type expected by the recipient is determined by analyzing the opening format when the recipient views the historical attachment file, so that the format of the attachment file in the mail is converted into the format type expected by the recipient, and not only is the work efficiency improved, but also the recipient can conveniently receive the attachment file of the expected format type.

The method can be operated in terminals such as smart phones (such as Android phones, IOS phones and the like), tablet computers, notebook computers, smart devices and the like. As shown in fig. 5, the steps of the method include S401 a-S405.
S401a, if it is detected that the existing attachment file is accessed, storing the access record of the accessed attachment file in a target database, wherein the access record comprises the user name of the visitor, the current format of the accessed attachment file and the corresponding accessed time.
In this embodiment, generally, the recipient can access the existing attached file associated under the user name of the recipient, and in order to complete the target database, it is necessary for the mail server to store the access record of the accessed attached file in the target database when receiving the request of the recipient to access the existing attached file, that is, the target database can be updated in time, so that the desired format type of the recipient can be analyzed more accurately.
S401, if a mail sending request is received, determining corresponding mail transmission parameters according to the mail sending request, wherein the mail transmission parameters comprise the initial format of an attachment file.
S402, determining the target format of the attachment file according to the access record in the target database, wherein the data in the target database is used for describing the corresponding relation between the attachment file and the target format.
S403, judging whether the initial format of the attachment file is the same as the target format.
S404, if the initial format of the attachment file is different from the target format, converting the attachment file from the initial format to the target format to obtain the target attachment.
S405, the target attachment is sent as a mail attachment.
