The project is based on WeChat applet development, providing users with a medical teaching platform, allowing users to use the Internet to easily and quickly view 3D human anatomical models. The project platform meets the teaching needs of medical students now, increases the practical opportunities for medical students, and reduces the psychological barriers of students who are afraid to learn because they cannot observe the actual human body system. Meet inexperienced doctors who can have actual combat experience; Let people interested in human anatomy have resources to learn about this knowledge. In terms of user use, the project aims to improve the user's interactive experience, so that users can feel the human body system three-dimensionally and truly, and observe the human anatomical model from different aspects. In terms of interface design, the project is mainly beautiful, simple and convenient. In terms of performance requirements, minimize the response time of the system, maximize the consideration of possible problems in system operation and solve them in time; In terms of functional structure, we provide 3D human anatomical models with core functions such as purchase and collection. The small program separates the front and back ends, uses JSON format for data exchange and transmission between the front and back ends, and the back end is written using NodeJs-based programs, providing an Https-based API interface for common foreground calls. At the same time, data exchange is carried out through JSON. The front end accesses the digital model database (storing basic information of the digital model) through the calling interface. The information returned by the database is sent back to WeChat applet in JSON format, and the 3D anatomical medical model is displayed to the user through a convenient WeChat applet. The back end (administrator) accesses the user behavior management system through JSON data exchange, call the interface to access the user behavior information base (storing information such as user behavior), so that the administrator can add, delete, check and modify the user's data.
