1、使用Chrome开发者工具分析网络请求

使用curl发送请求

2、HTTP协议组成

②request：

request：get、post、put、delete、head

header：host cookie user-agent

get query

post body：json xml form

③response：

status line

header

body

使用curl发送请求

3、copy as curl功能

使用curl发送请求

可以脱离浏览器进行请求

复制后在bash中粘贴，回车

使用curl发送请求

copy as curl的作用

①把浏览器发送的请求真实的还原出来

②附带了认证信息，所以可以脱离浏览器执行

③可以方便开发者重放请求、修改参数调试，编写脚本

4、客户端模拟请求工具

①nc（Navicat） tcp/udp协议发送

②curl最常使用的http请求工具

③postman综合性的http协议测试工具

④代理工具、IDE工具、浏览器插件工具

5、curl常见用法

①url=http://www.baidu.con

②get请求 curl$url

③post请求 curl -d xxx $url xxx–传递需要发送的字段

④proxy使用 curl -x http://127.0.0.1:8080 $url

6、curl重大参数

①-H “Content-Tpye:application/json”消息头设置

②-u username:password 用户认证

③-d 要发送的post数据 @file 表明来自于文件

④–data-urlencode page_size=50 对内容进行url编码

⑤-G 把data数据当成get请求的参数发送，常与–data-urlencode结合使用

⑥-o 写文件

⑦-x 代理 http代理 socks5代理

⑧-v verbose 打印更详细日志

⑨-s 关闭一些提示输出

url=http://www.baidu.com
