The Linux command simulates a GET or POST request for HTTP

HTTP request refers to the client to the server request message, the HTTP request is mainly divided into get or post two, under the Linux system can use the curl and the wget command to simulate HTTP requests.

GET Request:

1. Use the Curl command:

Curl "http://www.baidu.com" if the URL here points to a file or a picture can be downloaded directly to the local

Curl-i "http://www.baidu.com" Show All information

Curl-l "http://www.baidu.com" only displays header information

Curl-v "Http://www.baidu.com" shows the full process of GET request parsing

2. Use the wget command:

wget "http://www.baidu.com" can also be

POST request

1, using the Curl command (through the-d parameter, the access parameters in the inside)

Curl-d "Param1=value1&m2=value2" "http://www.baidu.com"

2, use wget command: (--post-data parameter to achieve)

wget--post-data ' User=tom&password=password ' http://www.baidu.com

This is how Linux simulates the GET or POST request for HTTP, so the Linux system can send messages to the remote server as well.   

Example: wget--post-data= "User=tom&password=password" http://www.baidu.com/login

Curl can send formatting requests such as JSON directly

Example: Target http://www.baidu.com/login

Command: Curl-h "Content-type:application/json"-X post-d ' {"User": "Tom","password": "Password"} '/ HTTP/ Www.baidu.com/login
