The article tells the author's experience of exploring and finally choosing the Cloud Patrol Forum as an open source project for deployment and secondary development in order to meet the requirements of laboratory teachers during his freshman year. During the summer vacation, the author sorted out the front and back code of the Cloud Patrol Forum, wrote automated deployment scripts, and fixed some functions. However, due to the huge amount of currency system code involved in the project and difficulty in modification, coupled with the numerous academic matters, the author finally decided to give up Further development, the project warehouse has been publicly available for others to study and star.

By analyzing the access paths and request characteristics of the online education system, this paper initially determines that it adopts Spring MVC front-end architecture and Tomcat is the Web server. It was found that there were differences in the routing rules of login and course selection Captcha. The login Captcha uses a route at the end of a do and passes parameters by the request body, while the course selection Captcha transfers information through request parameters in the route at the end of a do, reflecting the implementation differences of the system on different functional modules. In the end, the author wrote an automated course selection script based on the research results and provided a private repository for others 'reference.
