The Key Technology Research Of English Network Teaching Platform

Learning English through textbooks and teachers has long been the main model of English teaching. But with the rapid development of information technology, English networking teaching platform is becoming an important supplement to English teaching and this new model is based on the traditional one. The appearance of College English Networking Teaching Platform makes the English learning no longer be restricted by space and time and helps it develop to self–study. So the design and development of platform is becoming a current hot research in English Learning.The paper mainly studies the interface design of English networking teaching platform and the module design of book verification, it also realizes an English networking teaching platform. The main works are presented as follows:Firstly, to tackle the problem that the existing web page can not adapt to the various sizes of terminal screens or be compatible with a variety of browsers or show the new interface style, the system adopts the latest front-end development framework technology——Bootstrap, which can resolve the defects of existing interface in beauty, compatibility,adaptability. Furthermore, Aiming at the problem that each subsystem interface style is not unified and the amount of interface code is too large,the system develops a Bootstrap interface template which research incode generation technology based on the NVelocity template engine.using the new interface template can automatically generate Bootstrap interface,which can resolve the problem that each subsystem interface style is not unified and the amount of interface code is too large, save the time of developing interface and improve the developing efficiency.Secondly, to tackle the problem that the school administrator is easy to juggle verification results and verification mode is unitary, a book verification system is designed. The main design idea as follows: At first,for the problem of the unicity of verification mode, the system combines online verification mode with offline verification mode, which can make schools choose different verification modes according to different networking environments. Secondly, for the administrator right of schools’ offline verification is too much and the result of verification is easily modified, the system adopts MD5 encryption algorithm to encrypt return value which has been successfully verified. finally, for the problem of MD5 encryption algorithm is easy to be cracked through looking up Table Method, the system not only adds random string twice but also uses the method of substitution ciphers as well as hides the feature of encrypted hash value and confuses the attackers’ judgement on specific encryption algorithm, therefore, the safety of the system will be increased.
