Small program-based file transmission processing method and system

Abstract

The invention discloses a small program-based file transmission processing method and system, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: after receiving a file downloading request, calling a file downloading interface to execute a file downloading operation according to the file downloading request; after the file is downloaded successfully, judging whether cache of the applet client can store the request file or not according to cache file information of the applet client; if not, clearing part of cache files in the small program client cache according to a first cache clearing algorithm until the small program client cache can store the request file; and when the applet client cache can store a request file, writing the request file into the applet client cache, and updating cache file information of the applet client. According to the embodiment, the problem of downloading failure caused by cache overrun during file downloading is solved, and the file transmission stability is improved.

Description

Technical field [0001] The present invention relates to computer technology, and in particular relates to a method and system for handling a file transfer based applet. Background technique [0002] No need to install a small program application can be used. Existing small programs usually supports file transfer capabilities. [0003] In implementing the present invention, the inventor finds at least the following problems in the prior art: first, the client cache is limited storage capacity, if the total size of all the files downloaded file is larger than the local cache client cache Cache Threshold , the downloaded file will not be saved to the client cache, resulting in file download failed, poor user experience; second, the existing file upload applet, upload interfaces support only a single single-file uploads, as the user will pictures uploaded to cyberspace albums and other similar scenarios, users need to upload one by one, upload files efficiency is too low, the same re...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: first, the storage capacity of the client cache is limited, if the total size of the downloaded file and all files in the local cache is greater than the cache threshold of the client cache , the downloaded file will not be saved to the client cache, resulting in file download failure and poor user experience; second, when the existing applet uploads a file, the upload interface only supports a single file upload. In similar scenarios such as uploading pictures to cyberspace albums, users need to upload them one by one. The efficiency of uploading files is too low, which also leads to poor user experience; third, the file download interface only supports GET requests, and all parameters of GET requests are displayed. On the request path, the packet capture tool can obtain the parameter values ​​on the request path, resulting in low security of the file transfer interface and easy leakage of user privacy data
