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 ...

–user-agent 模拟一下其他浏览器看看 ...
