3. Project macro structure
I. Project module introduction
At the core of our project are two modules:
1. compile_server : Compile and run the module.
2. oj_server : file/database interaction, web page rendering, load balancing, and other functions.
II. Macro structure diagram of the project
III. Writing ideas
Adopt the idea of realizing from the back end to the front end
1. Write compile_server first
2. oj_server
3. version1 file-based online OJ
4. Front-end page design
5. version2 MySQL-based online OJ
First write the overall structure (what functions are needed), and then implement the function details (including adjustment of return value and parameters)
Four, compiler_server directory
1.compiler.hpp (compile module)
2.runner.hpp (running module)
3.compile_run.hpp (integrated module for compilation and operation)
4.compile_server.cc (handle network requests for compiling and running code)
5. Use Postman to test compile_server as a whole
Postman is a powerful tool for debugging web pages, sending HTTP requests and running interface test cases
Can simulate various HTTP Requests such as GET, POST, header, PUT, DELETE...etc
Files (pictures, text files, etc.), additional headers, etc. can also be sent in the request to implement specific interface tests
Can efficiently help back-end developers to independently test interfaces

You can also install the Postman plugin in chrome
