libcurl 模拟登录的问题求助

[不要做咸鱼]

学习c++ 的libcurl过程中遇到了一些问题，在模拟登录虾米网的时候不知道为什么会出现下面的错误
< HTTP/1.1 302 Moved Temporarily
< Server: Tengine
< Date: Tue, 04 Mar 2014 06:53:39 GMT
< Content-Type: text/html; charset=utf-8
< Transfer-Encoding: chunked

* Closing connection #0
* Issue another request to this URL: 'http://www.xiami.com'
* Violate RFC 2616/10.3.3 and switch from POST to GET
* About to connect() to www.xiami.com port 80 (#0)

下面是源码：求高人给个思路，或者给指出错误在哪谢谢了

用httpwatch 看到的post数据是这个样子的，我很纳闷这个token是从哪里获取的呢 _xiamitoken=819938e694aa2024c49f2a0c362831e3&done=http%253A%252F%252Fwww.xiami.com%252F&type=&email=5308****@qq.com&password=passwd&submit=%E7%99%BB+%E5%BD%95

我擦，半天都没人么

[bluesky12312388]

看了下，

<script>
    _xiamitoken = '4d34e7e68d0772e9497a4891d1f54e21';
</script>

这个应该是服务端随机生成的，用来校验。 所以你要先用libcurl获取 https://login.xiami.com/member/login 这个页面，取出_xiamitoken 然后再去用这个取到的token模拟登陆。

那提示302 应该不会是token不正确吧？
