From the perspective of our own students, we analyze and investigate the many problems of the traditional campus social platform, put ourselves in the social consideration of college students, and really use the learned technology to solve the practical problems of the campus. Starting from the pain point and realizing it with technology, I hope my works can serve the national colleges and universities. We set up modules such as campus matters, question and answer area and interest circle in "Garden Knowledge", which facilitates timely communication among college students and broadens their social circle. The key point is that the third-party platform is no longer required to be responsible for forwarding, and it is completely controlled by the students themselves, making the campus social interaction more free and easy. In terms of development, we use the front-end separation development model, and gradually realize the many benefits of this new model, such as improving development efficiency, making the division of labor clearer, and enhancing the maintainability of the code. We have gained a lot of experience and inspiration from the actual combat of the project, and we also advocate the pursuit of the most popular technology at present, keep up with the cutting-edge technology trend of the society, step by step, and help more people with the technology we have learned. Although we have successfully implemented the application with front-end separation, the technology currently used is only the tip of the iceberg. There are more new fields waiting for us to explore and explore. There are still many areas in the project that need to be optimized, so we will always Maintain this project and thrive together with "Yuanzhi. The park knows that the project is divided into small program mobile terminal and background management PC terminal. In the student side of the small program, there are mainly three functional modules, namely "campus post", "campus question and answer" and "interest circle". students can choose the modules they are interested in to browse. the information content displayed by each module is also switched according to the schools bound by the students. the contents of different schools are independent of each other and do not affect each other. In order to facilitate the "director" to manage the content of small programs, in the supporting background management system, the "director" can review and manage all the module contents of his school, such as "personnel management", "campus post management", "question and answer management" and "interest circle management". the director's authority of each school is clearly divided and independent of each other. Today, with the rapid development of the Internet, college students' social networking needs are increasing day by day, and social platforms in various colleges and universities across the country have emerged in large numbers and have a good momentum of development. According to the survey data released by China Internet Network Information Center (CNNIC) in July 2020, among about 26.5 million Internet users in China, college students aged 18-24 account for 36.8, and the Internet access rate of college students is 84%. Mobile phones have become the main tool for college students to surf. Therefore, social platforms such as mobile campus forums and post bars emerge as the times require. Due to the high coincidence of age, cultural education, social experience and living environment, campus communities provide students with a platform for sharing common interests and topics, talking, communicating and asking for help. Among them, the "campus confession wall" greatly meets the psychological needs of college students to obtain multiple information and participate in public opinion due to its characteristics of popularity and interactivity, constantly integrate into the daily life of college students.
