Design And Implementation Of Register System Based On Web Service

As a revolutionary network technology, Web makes the network be popular from prerogative, and become more and more important for people's work and life. Web let the information release become easy. The active Web brings convenience to people. So, design and complete a Register System for students is significance and needed.Based on the analysis of requirement, the design principles of the WRS system are explained, the system structure, work processes and function modules of the system are described.The identity verification of the WRS system, including the control method preventing the lawless access, is discussed. The models and control project of the WRS system are described, including the design of the regular expression which verifying the client words, the basic function of the database pool and the method processing the superabundant request which based on the token. For the security of WRS system, the issues on web security are researched and discussed. The security project has been designed for the WRS system, including the password encryption, data filtration, validated code and error control. In the encryption field, the mode of assemble the password and the arithmetic of encryption are particular discussed. In the data filtration field, the SQL injection has been discussed and researched, the regular expression preventing it are designed. In the validated code field, the method disturbing the auto program identify are discussed, the way of generating the validated code string is described. Finally, the error objects of the whole system possible occurring are analyzed.The system we've designed can satisfy the requirement of the students, works efficiently at lot of requesting condition, and prevent the attacks. The WRS system is a practical, secure, expansible Web application system.
