Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Currently, when multiple people edit the same document, there are generally two implementation ways:
one is an off-line approach, such as git, where different users edit the same document locally, and when they are submitted to the server, they compare the document with the contents of the server to find out the differences, and then merge the differences. Although the method has low dependence on the server, does not need real-time online, and only needs to connect the server when submitting modification, the method is easy to generate conflict, when different users respectively edit the same part of content, the conflict can be generated, and git can require the users to solve the conflict, generally the users who submit modification later to solve the conflict;
the other is real-time updating, for example, Google docs has one or a group of servers, the server stores the document content being edited, Google docs sends the content edited by each user in real time, all users are connected with the server, and when any user modifies the document, the server sends a request to update the document content, and the latest document is displayed on the page. The document contents are downloaded from the server to the local by each user through respective client (e.g. browser), and displayed on the client for the user to edit. The google docs takes the whole document as a streaming media (stream), when a user edits the document, the current position is an offset from the beginning of the document, then the content input by the user is recorded, usually, the currently modified content is sent to the server within 1-5 seconds after the user modifies the content, after the modified content is sent to the server, the client can continue to record the next modified content of the user and continue to send the modified content to the server, and if the user continuously inputs the content, the client needs to frequently send data to the server.
When the two modes realize multi-user real-time editing, document conflicts are easily caused, for example:
the current document content of a shared document is as follows: "123456123456";
at a certain time, the user A and the user B edit the document at the same time, the user A adds the character string "abc" at the position of the offset 3, and the user B adds the character string "def" at the position of the offset 6, at this time, the document content of the user A is "123 abc 456123456", and the document content of the user B is "123456 def 123456";
after editing is finished, the user a and the user B respectively send the edited document content to the server, and ideally, the edited document content of the shared document is "123 abc456def 123456";
if the server receives the document content of the user A first, the edited document content of the shared document is '123 abc 456123456', and then receives the document content of the user B, the edited document content of the shared document is '123 adcdef 456123456', and the final document content is different from the expected (i.e. ideal situation);
if the server receives the document content of user B first, the edited document content of the shared document is "123456 def 123456", and then receives the document content of user A, the edited document content of the shared document is "123 abc456def 123456", and the final document content is the same as the expected content.
Document conflicts can arise when multiple people edit simultaneously online because the sequence in which the server executes the commands is not controllable.
Therefore, the method for editing the document of the embodiment of the invention adopts a locking mechanism, the document is locked before the user edits the document, the editing operation is executed after the locking is successful, and the locking is unlocked, and the failure of the locking indicates that the user edits the document at present and can not execute the editing operation, thereby reducing the situation that the document conflicts occur when a plurality of users edit the same document. Meanwhile, a block chain technology is adopted, and a method for editing a document in real time on line by multiple persons is provided by utilizing the decentralized anti-tampering characteristic of the block chain technology, so that the authenticity and the correctness of document editing can be effectively guaranteed.
Fig. 1 is a schematic diagram of main steps of a method of editing a document according to an embodiment of the present invention.
As shown in fig. 1, the method for editing a document according to the embodiment of the present invention mainly includes the following steps:
step S101: and acquiring the document name and the editing information from the editing request.
For a scene in which a plurality of people edit the same document, the online real-time editing system stores the shared document, and a user in communication connection with the online real-time editing system through a client (such as a browser) can edit the shared document. After the user finishes editing, the user can send the editing request to the online real-time editing system to edit a certain document.
The editing information may include an editing position, an editing type, and editing content, where the editing position refers to which part of the document is edited at this time, the editing type refers to which operation is performed on the document, main editing types include addition, deletion, and replacement, and the editing content refers to which modification is performed on the document.
In the embodiment of the present invention, step S101 may be implemented by: receiving an editing request sent by a user; and analyzing the editing request according to the sequence of the received editing requests to obtain the document name, the editing position, the editing type and the editing content.
When a plurality of people edit the same document, the user can send the document editing through the editing request, and the editing requests sent by the users are analyzed in sequence, so that the editing requests are processed in order.
Step S102: and locking the target document according to the document name.
And after the document name is analyzed from the editing request, the target document can be determined, and in order to reduce the problem of document conflict, the target document can be locked, if the locking is successful, the step S103 is continuously executed, and if the locking is failed, the step S104 is continuously executed. In addition, locking refers to that a target document can only be edited by a user corresponding to an editing request which triggers a locking operation, and it is ensured that the target document can only be edited by one user at the same time.
In the embodiment of the present invention, step S102 may be implemented by: inquiring a target block chain corresponding to the document name in a block chain network by using an intelligent contract; if the document name is not inquired, creating a target block chain corresponding to the document name in the block chain network according to the document name, and locking the target block chain; and if the document name is inquired, locking a target block chain corresponding to the document name in the block chain network.
The method for editing the document in the embodiment of the present invention may store the shared document by using a block chain network, that is, the document contents edited by multiple persons are stored in the block chain network, which may be a block chain platform such as a super book, wherein each document block chain in the block chain network is used to store a target document, and each document block chain may further include a plurality of sub-document blocks connected in time sequence, and each document editing uses one sub-document block for storage. When a target document is locked, the document name can be searched in a block chain network by using an intelligent contract, namely a target block chain corresponding to the document name is found from each document block chain, the target block chain stores the target document, in the process, if the document name is not inquired (namely the target block chain is not found), the target document corresponding to the editing request does not exist, a block chain can be newly built as the target block chain, and the target block chain is locked after being found.
The method for editing the document, provided by the embodiment of the invention, provides a reliable storage scheme for multiple people to edit the shared document online in real time based on the block chain technology, and simultaneously combines the block chain technology with a locking mechanism, so that the problem of document conflict caused by uncontrollable sequence of commands executed by a server when multiple people edit online simultaneously is solved.
Block chain in narrow sense, the block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged is guaranteed. Broadly, the blockchain technique is a completely new distributed infrastructure and computing approach that utilizes blockchain data structures to verify and store data, utilizes distributed node consensus algorithms to generate and update data, utilizes cryptography to secure data transmission and access, and utilizes intelligent contracts composed of automated script code to program and manipulate data. In order to ensure the transaction performance, the block chain requests are performed in a serial mode and are completely serial, the requests are sequenced firstly, and then the intelligent contract is executed by using a single thread, so that transaction confusion, data conflict and the like caused by out-of-order execution are avoided. Due to the tamper resistance of the block chain, the document content can be traced, the latest total document content can be uniformly inquired for each user, and the data inconsistency is avoided. Intelligent contract: the intelligent contracts are only certain code of a block chain encryption currency network running on a computer (or other nodes), and once the node executes the code, the contracts update a general ledger (hedger). A developer may write code for an intelligent contract. The intelligent contract may be used for any exchange activity between two/more parties. The code contains conditions that trigger the automatic execution of the contract. When the trigger condition of the intelligent contract is reached, the corresponding affair is executed, and the corresponding result is returned; when the query method in the executed intelligent contract returns a corresponding result, and when the newly added write method in the executed intelligent contract, the latest result is placed in the latest block.
Step S103: and editing the target document based on the editing information.
If the locking is successful, the user can edit the target document, and the editing operation on the target document is completed based on the editing information.
In the embodiment of the present invention, step S103 may be implemented by: acquiring a target document from the latest sub-document block of the target block chain by using an intelligent contract; newly adding the editing content in the target document based on the editing position; and/or deleting the edited content from the target document based on the editing position; and/or, replacing the edited content in the target document based on the editing position; caching the edited target document into a document cache; and newly adding a sub file block in the target block chain to store the edited target document, and unlocking the target block chain.
When the target document is edited based on the editing information, the target document is obtained from the latest sub-document block, namely the latest sub-document block in the target block chain, the target document with the latest content is stored in the latest sub-document block, the target document is edited such as adding, deleting and replacing according to the editing information, the edited target document is stored in two ways of caching the edited target document in a document cache and storing the newly added sub-document block respectively, and finally the target block chain is unlocked. The document cache is a system cache of an online real-time editing system, and is used for enabling other users to obtain the latest content of a target document during locking, so that the other users can edit the target document conveniently, for example, Redis is used as the system cache, and Redis is a high-performance key-value database.
Step S104: and reading and displaying the current content of the target document.
If the locking fails, it indicates that the user cannot edit the target document, and at this time, the current content of the target document (i.e., the basic content of the next editing) may be presented to the user.
In the embodiment of the present invention, step S104 may be implemented by: reading the edited target document from the document cache according to the document name; and displaying the edited target document to a user.
The edited target document stored in the document cache, that is, the latest content of the target document, on the basis of which the user can adjust editing information and the like.
As a preferred implementation manner, as shown in fig. 2, the method for editing a document according to the embodiment of the present invention can be implemented by referring to the following flow:
step S201: receiving an editing request sent by a user;
step S202: analyzing the editing request according to the sequence of the received editing request to obtain a document name, an editing position, an editing type and editing content;
step S203: inquiring a target block chain corresponding to the document name in the block chain network by using an intelligent contract, and locking the target block chain:
if the document name is not inquired, creating a target block chain corresponding to the document name in the block chain network according to the document name, and locking the newly-created target block chain; if the document name is inquired, directly locking the target block chain;
when the locking is successful, executing step S204; when the locking fails, executing step S208;
step S204: acquiring a target document from the latest sub-document block of the target block chain by using an intelligent contract;
step S205: editing the target document by using the intelligent contract:
newly adding edited content in the target document based on the editing position; and/or deleting the edited content from the target document based on the editing position; and/or, replacing the edited content in the target document based on the editing position;
step S206: caching the edited target document into a document cache;
step S207: newly adding a sub-file block in the target block chain to store the edited target document, and unlocking the target block chain;
step S208: reading the edited target document from the document cache according to the document name;
step S209: and displaying the edited target document to a user.
According to the method for editing the document, the document name and the editing information are obtained from the editing request; locking the target document according to the document name; when the locking is successful, editing the target document based on the editing information; when the locking fails, the technical means of reading the current content of the target document overcomes the technical problem that document conflict is easily caused when different users respectively edit the same part of content, thereby achieving the technical effects of reducing document conflict and effectively ensuring the authenticity and correctness of document editing.
In order to further illustrate the technical idea of the present invention, the technical solution of the present invention will now be described with reference to specific application scenarios.
As shown in fig. 3, it is assumed that user 1 accesses the online real-time editing system through machine a and user 2 through machine B, and machine a and machine B are clients for implementing editing operations, respectively, and the online real-time editing system may also have other machines. When the method for editing a document according to the embodiment of the present invention is applied, the following processes may be referred to:
1. after receiving the editing request of the user 1, the machine A executes distributed locking on a shared document (namely a target document) corresponding to the editing request, if the locking fails, the document content of the shared document is read from a cache, the edited document is returned after the editing failure, and if the editing failure does not occur, the 'zero' (namely a null value) is returned; if the locking is successful, triggering an execution function of the intelligent contract, acquiring a corresponding shared document (namely a target block chain) corresponding to the editing request from the block chain network, if the shared document does not exist at first, initializing the document content to be "" i.e. newly creating the shared document and locking, and then executing the editing request of the user 1 (namely executing the step 2);
it should be noted that, executing the distributed locking on the shared document is performed in a single machine (for example, machine a and machine B), and after the locking is successful, an editing request is initiated on the target block chain, and the target block chain receives the editing request and triggers an execution function of the intelligent contract. The execution function is a code written by a developer in advance, and the execution function has entry references, wherein the entry references are a document name, an editing position, an executed operation (namely an editing type) and an executed character string (namely an editing content) carried by an editing request in the embodiment of the invention;
2. an executing function of the intelligent contract initiates a request for editing a shared document, namely adding a character string 'abc' (namely new editing content) at a position (namely an editing position) of an offset 0, writing the latest document content 'abc' (namely an edited target document) into a redis cache, storing the document content in the redis cache by using a document name as a key, storing the current shared document 'abc' into a newly-built block A (namely a newly-added sub-document block), unlocking a target block chain, and returning the edited target document and the successful editing to a user 1;
3. after receiving the editing request of the user 2, the machine B also executes distributed locking on the shared document corresponding to the editing request in the machine B, if the locking fails, the editing request of the user 1 is not processed, at this time, the document content of the shared document is read from the cache, the edited document of the editing failure person is returned, and at this time, if the query fails, the "" is returned (namely, a null value); if the locking is successful, triggering an execution function of the intelligent contract, acquiring a shared document (namely a target block chain, at the moment, only including a block A) corresponding to the editing request from the block chain network, and acquiring the shared document 'abc' (namely the target document) from the block A (namely the latest sub-document block);
4. after the locking is successful, an execution function of the intelligent contract initiates a request for editing the shared document "abc", namely, a character string "edf" (namely, newly-added editing content) is added at the position of the offset 3 (namely, the editing position), the latest document content "abcedf" is written into a redis cache, the current document content "abcedf" is stored into the latest block B (namely, a newly-added sub-document block), then, a target block chain is unlocked, and the edited target document and the editing success are returned to the user 2, wherein the target block chain comprises a block A and a block B at this time;
the above steps 3-4 are repeated in a loop, so that the editing process of the shared document by multiple users can be completed, for example, a user can delete the character string "ce" (i.e. delete the edited content) at the position of the offset 2 (i.e. the editing position) by the way of steps 3-4, and the final target block chain includes the block a and the block B … … block N, so that the data change history of the shared document is recorded in a non-falsification manner.
