1 cURL简介




curl还支持SSL认证、HTTP POST、HTTP PUT、FTP上传, HTTP form based
upload、proxies、HTTP/2、cookies、用户名+密码认证(Basic, Plain, Digest, CRAM-MD5, NTLM,
Negotiate and Kerberos)、file transfer resume、proxy tunneling。

linux和window10可以直接使用curl,window10 以下可以到https://curl.haxx.se/windows/ 下载安装

2 linux centos下请求


3 window10 cmd下请求




2、通过 chcp命令改变代码页,UTF-8的代码页为65001

  chcp 65001



在命令行标题栏上点击右键,选择"属性"->"字体",将字体修改为True Type字体"Lucida Console",然后点击确定将属性应用到当前窗口。

4. curl命令使用(以linux为例)
