May I know what api interfaces and api documents are, and what api we usually refer to is the interface, my small front end

The full name of API is Application Programming Interface. If you are the front end, you will definitely feel nauseous. This definition is generally defined and written by the back end. Of course, it should be said that depending on the situation, you can also say that you are responsible for the interface document with the back end when you initially decide the project. Of course, this situation is relatively rare. In fact, if the interface document is a URL in node, then it is req.query () or req.url. Some of the things you get suggest that you download a postman special test interface and can also transfer the document, which is very good for you to process the interface data.
