浏览器获取的内容和curl获取的不一致
返回是一个JSON字符串 但是我用curl -l http://.... 却无法获取
返回
<code> <title>404 Not Found</title> <h1 id="Not-Found">404 Not Found</h1> The requested URL /mauth/usr/exists was not found on this server. </code>

问题后来发现是网络链路的问题的,执行curl那台主机与目标服务器是隔绝的,无法互相访问的,蛋疼!
User-Agent, Cookies, Accept, Referer等各种参数都会影响请求结果。
我一般先用Fiddler找出最少需要的参数与Cookie,然后弄curl。
来,最新版本的chrome的javascript调试工具里已经支持Curl复制(它可以完全模拟浏览器访问,包括header,cookie,操作系统信息等),具体是 先打倒network 上,之后访问这个页面 之后在那个list点右键,有个copy as curl。之后直接curl的干活
URL 写错了吧 ... 或者是服务端对 User-Agent 做了限制 ...
用 –user-agent
模拟一下其他浏览器看看 ...
