Method for realizing file downloading locking synchronization on webpage

Abstract

The invention belongs to the technical field of networks and particularly relates to a method for realizing file downloading locking synchronization on a webpage, which comprises the following steps that: when a source user opens a webpage, the webpage requests a server to load a file list having a file downloading function and determines if files can be downloaded according to the downloading states of the files; a loading Flash establishes permanent connection with a communication server, changes the state from 'allowed' into 'prohibited' or from 'prohibited' into 'allowed' when the user performs downloading locking operation of a single file and asynchronously requests the server to store the downloading state of the file in the server; and the Flash synchronize the downloading state into other target users, so that the target users can call a webpage function to change the downloading state of the corresponding file after receiving the downloading state. The method can realize file downloading locking synchronization based on the webpage completely, and is convenient, quick and efficient.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a method for realizing file download lock synchronization on a web page. Background technique [0002] With the development of Internet software and hardware, multimedia informatization has been popularized, and people use more multimedia technologies in their daily communication, such as mobile phones, telephones, and voice communications. Information sources such as news, books, audio and video cover the entire Internet. People obtain a huge amount of information from the Internet every day. At the same time, the security of resources is also exposed. This is a very serious problem. Resource files such as confidential materials are downloaded and embezzled at will, resulting in serious damage to information resources. Especially in high-serious occasions such as network video conferencing, distance education, and file sharing systems, the uploaded and displayed fi...

Problems solved by technology

Confidential materials and other resource files are downloaded and embezzled at will, resulting in serious damage to information resources

Especially in high-serious occasions such as network video conferencing, distance education, and file sharing systems, the uploaded and displayed files are extremely important. If these files are downloaded or stolen at will, it will cause very serious consequences

In order to prevent such a situation, the traditional method is to hide the file and not allow downloading, but the user operation and experience effect of these methods are very unfriendly

Moreover, even if the download lock can be realized, the synchronization lock cannot be realized, which will inevitably affect the effect of remote synchronization application systems such as video conferencing and distance education, so that the security of files cannot be protected; some systems that need to download and install controls may realize Synchronous locking, but not based on web pages, which will have a certain impact on the user's software and hardware, and may bring great security risks
