Problems solved by technology

[0004] In the existing network-based learning process, course resources rely on the cache of the browser, but the cache of the browser is usually small in capacity and poor in stability, resulting in the need for the browser to download data from the server every time learning, causing extreme damage to the server. big pressure
[0005] In addition, since the files in the browser cache are not encrypted, they are easy to be copied by illegal users, which will cause losses to course resource providers

Embodiment Construction

[0048] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The following describes the course resource downloading method provided by the embodiment of the present invention from the server side, refer to figure 1 , figure 1 It is a flow chart of the course resource downloading method provided by Embodiment 1 of the present invention.

[0050] In this embodiment, the method for downloading course resources specifically includes:

[0051] Step S101, receiving uploaded course resources, and dividing each file of the course resources into blocks to obtain course blocks.

[0052] In this embodiment, the server can receive the course resources uploaded by the courseware provider, and the server will perform a scanning process on the course resources. The scanning process first needs to block each file of the course resources to obtain the course blocks, and then perform t...

Abstract

The invention relates to a course resource downloading method, a course resource server, clients and a system. According to the course resource downloading method provided by the invention, as a downloaded base unit is course blocks, the course blocks not only can be stored on the server but also can be stored on other clients, one client only requests resource downloading information to the server during downloading course resources first, and the client can request the course blocks to other clients to realize the subsequent downloading process. Thus, the burden of the server is reduced. In addition, the course resource downloading process does not depend on a browser, the downloaded course blocks can be directly stored in local cache, and the stability of cache is also increased.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a course resource downloading method, a course resource client, a server and a system. Background technique [0002] With the development of information technology, E-Learning has gradually become popular as a new learning method. Network learning is inseparable from a new network learning environment composed of multimedia network learning resources, online learning communities and network technology platforms. In the network learning environment, a large amount of data, archives, programs, teaching software, courseware and other course resources have been collected to form a highly integrated resource library. [0003] In the traditional E-Learning process, course resources are usually stored in the server, and access to course resources needs to be realized through a browser. The user accesses the learning website through a browser, and the course resources are...
