FIG. 1 is a schematic flowchart of a method for updating a file according to an embodiment of the present invention. As shown in FIG. 1 , the method includes: S1, after receiving a request message for acquiring configuration file data from a server, receiving configuration file data returned by a server; The configuration file is a text type file for storing the information of the file to be updated generated by the server in advance; S2, parsing the configuration file data, and obtaining a name and an MD5 value of at least one file to be updated in the configuration file data. The MD5 value is used to check whether the file information is consistent; S3, if there are files to be updated and local files whose names and MD5 values are the same, the file to be updated is cancelled and the local file is retained.

The configuration file is a text type file preset in the server; the file records the information of the file to be updated, and includes at least the name or ID of the file to be updated, the download link, and the MD5 value. In the embodiment of the present invention, the mobile terminal may The data in the configuration file is obtained by sending a request message.

MD5, Message-Digest Algorithm 5, is used to ensure complete and consistent information transmission. It is one of the widely used hash algorithms (also known as abstract algorithm, hash algorithm). There are MD5 implementations; computing data (such as Chinese characters) to another fixed length value is the basic principle of the hash algorithm. The predecessors of MD5 are MD2, MD3 and MD4. The embodiment of the present invention selects the MD5 as a means for confirming whether the file information is the same, but the scope of protection of the embodiment of the present invention is not limited thereto.

In step S1, the mobile terminal first sends a request message to the server, where the request message carries information requesting to acquire configuration file data; after receiving the request message, the server may return a sending configuration file to the mobile terminal according to the request message. data.

Specifically, the file configuration interface function chaackCustomEmblemConfig is added on the mobile terminal, and the function is used to determine which files to be updated (compressed package files) are downloaded by the mobile terminal.

In step S2, according to the configuration file data obtained in step S1, the mobile terminal may further parse the configuration file data, and obtain information carried in the configuration file, where the information includes at least one related information of the file to be updated, and the related information includes at least File name and MD5 value. For example, if the file to be updated is a compressed package file, the name of the compressed package and the MD5 value corresponding to the compressed package are included after parsing.

The local file does not need to be updated. The same name is stored in the pre-created cancel download array doNotNeedDownLoadRoomIDArray. After traversing, canceling the download array saves the names of all files to be updated that do not need to be downloaded, and correspondingly, the names of all local files that need to be retained.

In step S32, performing a traversal operation on the array to be updated, first determining whether each file name to be updated has a corresponding download link zipUrl, and if so, proving that the file to be updated is downloadable; Whether the name is included in the cancel download array. If it is not included, it means that there is no file to be updated locally, and the file to be updated needs to be downloaded; otherwise, no download is required. After traversing, it is possible to complete the download operation for all files that are not present locally.

In addition, the name of the local file that needs to be preserved is also saved in the cancel download array, and then the delete operation is performed on the local file that does not contain the name in the cancel download array.

Double-layer loop traversal through arrays can effectively save code and improve performance.

On the basis of any of the above embodiments, the step S22 further includes: S23, determining whether the array to be updated is an array type, and if not an array type, terminating the file update.
