Http protocol supports the following methods to retrieve data such as get, post, put, delete etc. In this article, I will tell you about the difference between GET and POST methods.

Http协议支持以下方法来检索数据，例如get，post，put，delete等。在本文中，我将向您介绍GET和POST方法之间的区别。

These methods are basically used to get and send any data. Because of these methods, the request-response between server and client exist. To send data streams we use these two methods. GET and POST are the most common HTTP methods.

这些方法基本上用于获取和发送任何数据。 由于这些方法，服务器和客户端之间存在请求-响应。 要发送数据流，我们使用这两种方法。 GET和POST是最常见的HTTP方法。

Check out the example of both requests.

查看两个请求的示例。

**GET Request:**

**GET请求：**

GET https://api.github.com/users/\{name\}

获取https://api.github.com/users/\{name\}

Here you can pass name according to that you will get data.

在这里您可以根据您将获得数据的名称进行传递。

GET https://api.github.com/users/seeschweiler

**POST Request:**

**POST请求：**

In this you will have to send content-type such as multipart/form-data, application/json,  application/x-www-form-urlencoded and object or data that you have to pass in body.

在这种情况下，您将必须发送内容类型，例如multipart / form-data，application / json，application / x-www-form-urlencoded以及您必须在正文中传递的对象或数据。

Host: foobar.example

主持人：foobar.example

Content-Type: application/json

内容类型：application / json

Object- \[\{name1:value1\},\{name2:value2\}\]

对象-\[\{name1：value1\}，\{name2：value2\}\]

In this you are posting JSON data to API.
