Problems solved by technology

The biggest problem with this solution is that browser plug-ins or controls depend on the type of browser. Plug-ins or controls developed for one browser cannot be used in another browser, and corresponding plug-ins or controls need to be developed for different browsers. , that is, the interoperability of this scheme is poor
[0003] To address this problem, the applicant for this patent proposed a corresponding solution in his patent application "A Data and File Encryption Method for Browsers" (patent application number: 201410427298.4). One

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The HTTP communication between the browser and the file proxy program can be realized through automatic HTTP POST, local page link (HTTP GET), script program, including using HTML frame (FRAME), AJAX, etc.; using script program and local file proxy program Need to solve cross-domain script (CrossDomain Script) problem through HTTP. All of these are introduced in many public materials, and there is also a lot of information in this regard on the Internet.

[0018] The browser transmits to the local file agent program the URL representing the location of the uploaded or downloaded file in the Web server, the session identification data of the session between the browser and the Web server, and the local API instructions that need to be called (such as which API module and interface function name ) and the parameters for calling the local API can be encoded in the...

Abstract

The invention relates to a file uploading and downloading method. When a user uploads a file to a Web server through a browser page or downloads the file from the Web server; a browser transmits file uploading and downloading commands to a local file agent program of a user computer through HTTP (hyper text transport protocol); the file uploading and downloading operation processing, including the pop-up of a man-computer interface for the user to select the local file to be uploaded or to select the storage position of the downloaded file in the local area and to call a local API (application program interface) to process the file before the file uploading and during the file downloading, is completed by a file agent program; the browser transmits the file uploading and downloading commands to the file agent program, and meanwhile transmits conversation mark data of the conversation between the browser and the Web server to the file agent program; the conversion mark data is included into the a file uploading and downloading HTTP request submitted to the Web server by the file agent program in a mode of conversion mark data submission by the browser agreed by the Web server.

Description

technical field [0001] The invention belongs to the field of Web information technology, in particular to a method for processing uploaded and downloaded files without calling a local API through a browser plug-in or control when a user uses a browser to upload or download files. Background technique [0002] When people use the Web system, they often need to upload and download files through a browser. When uploading or downloading files, it is necessary to call a local API (such as a local cryptographic module) to process the uploaded or downloaded files (such as encrypting and / or digitally signing uploaded files, decrypting and / or or signature verification), the browser cannot do this directly. The usual practice is to use a specially developed browser plug-in (Plug-in) or control (such as ActiveX) to upload and download files, and in the process of uploading and downloading files, the plug-in or control calls the local API for uploading and downloading. File process ha...
