Common HTTP Request Methods and Their Descriptions

GET requests the specified page information and returns the entity body

POST sends data to the server for processing, and the data is contained in the HTTP message body.

POST requests submit data to the specified resource, request the server to process, such as: form data submission, file upload, etc., the request data will be included in the request body.

POST methods may create new resources or/and modify existing resources.

With POST, the query string exists separately in the POST message and is sent to the server with the HTTP request:

POST /test/demoform.html HTTP/1.1

Host: w3schools.com

name1=value1&name2=value2

Features:

POST requests cannot be cached

POST requests are not saved in browser history

The URL requested by POST cannot be saved as a browser bookmark

POST requests have no length limit

HEAD Same response as GET, only response header required

The HEAD method, like the GET method, makes a request to the server for a specified resource. However, the server does not return the content portion of the resource in response to the HEAD request, i.e., the response body.

In this way, we can get the response header information of the server without transmitting the whole content. The HEAD method is often used by clients to view server performance.

The PUT request uploads its latest content to the specified resource location, and the PUT method is idempotent. By this method, the client can transmit the latest data of the specified resource to the server instead of the contents of the specified resource.
