4. HTTP Request Overview

Testing and using the HTTP interface begins with understanding the basic concepts of HTTP requests:

• HTTP Request Generally speaking, the client sends data to the server via the HTTP protocol, and the server parses the information sent by the client according to the protocol.
• Commonly used request parameters:
  • GET Parameters GET Parameters: The URL is spliced after the request and is concatenated with a? symbol. For example:https://yours.tools/ ?a=b&c=d For example, the part after the question mark is the GET request parameter.
  • POST Parameters The POST parameters are not displayed in the URL, but in the body of the HTTP request.key=value The POST parameters can be passed in the form of a string, or in JSON or XML format. POST parameters can be passed in the form ofContent-Type The server parses the request according to different Content-Types.

Common Content-Type Types

• application/x-www-form-urlencoded : Commonly used for form submissions, the parameters are in the format of"a=b&c=d" The server is able to parse them automatically.
• application/json When sending JSON format data, you need to set the Content-Type in the request header, usually the server will read the stream in the request body to process the data.

5. Request and Response Header

• Request Header The header information sent by the client when requesting, it is used to inform the server about the client's situation, for example, whether it supports compression, accepted language, User-Agent, Referer, etc. Meanwhile, Cookie is also included in the request header.
• Response Header : The header information returned by the server to the client, including the request status code, caching policy, set cookies, etc. The browser receives the response and then sends it to the client. After receiving the response, the browser will set this information accordingly.
