linux 服务器执行post请求 curl命令详解

什么是curl？

curl是一个命令行访问URL的计算机逻辑语言的工具，发出网络请求，然后得到数据并提取出，显示在标准输出“stdout”上面，可以用它来构造http request报文，curl(CommandLine Uniform Resource Locator),即在命令行中利用URL进行数据或者文件传输。

基本语法：curl [option] [url]

实际用法

POST 请求 application/json

curl -H "Content-Type: application/json" -X POST  -d '{你的内容}' https://xxx.com/api

-H 请求头
-X 指定要使用的请求命令 POST 请求方式
-d 请求内容体 data的意思

如果遇到https访问证书的问题情况 可以使用 -l 来忽略证书问题请求

-1, --tlsv1         Use => TLSv1 (SSL)     --tlsv1.0       Use TLSv1.0 (SSL)     --tlsv1.1       Use TLSv1.1 (SSL)     --tlsv1.2       Use TLSv1.2 (SSL)     --trace FILE    Write a debug trace to the given file     --trace-ascii FILE  Like --trace but without the hex output     --trace-time    Add time stamps to trace/verbose output     --tr-encoding   Request compressed transfer encoding (H)

请求就变成

curl --tlsv1 -H "Content-Type: application/json" -X POST  -d '{你的内容}' https://xxx.com/api

GET 请求 带认证token

curl -G -H 'Authorization: xxx' https://xxx.com/api

-H 请求头
-G 指定请求为GET请求
-d 请求内容体 data的意思（可以自行添加）

其他请求方式 如 POST form/data 可以使用 -F

curl -X POST -F -H 'Authorization: xxx' -d '' https://xxx.com/api

-H 请求头
-F POST form-data形式请求
-d 请求内容体 data的意思（可以自行添加）

拓展超时时间配置

--connect-timeout   设置连接超时--max-time  设置请求超时
