curl工具常用选项高数
语法格式：
curl [options] [URL...]
常用选项如下所示:
-A/--user-agent :
设置用户代理发送给服务器
-e/--referer :
来源网址
--cacert :
CA证书 (SSL)
-k/--insecure:
允许忽略证书进行 SSL 连接
--compressed:
要求返回是压缩的格式
-H/--header :
自定义首部信息传递给服务器
-i:
显示页面内容，包括报文首部信息
-I/--head:
只显示响应报文首部信息
-D/--dump-header :
将url的header信息存放在指定文件中
--basic:
使用HTTP基本认证
-u/--user :
设置服务器的用户和密码
-L:
如果有3xx响应码，重新发请求到新位置
-O:
使用URL中默认的文件名保存文件到本地
-o :
将网络文件保存为指定的文件中
--limit-rate :
设置传输速度
-0/--http1.0:
数字0，使用HTTP 1.0
-v/--verbose:
更详细
-C:
选项可对文件使用断点续传功能
-c/--cookie-jar :
将url中cookie存放在指定文件中
-x/--proxy :
指定代理服务器地址
-X/--request command>:
向服务器发送指定请求方法
-U/--proxy-user :
代理服务器用户和密码
-T:
选项可将指定的本地文件上传到FTP服务器上
--data/-d:
方式指定使用POST方式传递数据
-b name=data:
从服务器响应set-cookie得到值，返回给服务器 curl命令测试HTTP协议实战案例
