Use postman to do front-end and back-end interface testing

postman is a tool that supports interface commissioning and testing of the HTTP protocol. It is powerful and easy to use. Common interface types are:

1 query parameter class (the part after the ? in the URL address, consisting of key-value pairs)

2. Form type

3. JSON type

4. Upload file type

 Steps:

1. Create a new request, select the http method, and fill in the URL.

2. Set the sending parameters (no need), and click the send button.

3. Get the response data and parse it, and display it on the front end.
