 验证码 要么人肉要么机器识别,机器识别要根据验证码的特征做处理,没那么简单.人肉嘛做个输入提交,带上cookie.

有验证码的做模拟登入太麻烦,要识别验证码。只要对方改个复杂的,就没办法了。

我是要人肉输入,验证码已经取到,现在在post的时候返回一个Object moved to here.
百度了下说是陷入了重定向,不懂爱这里犯迷糊了,不知该如何处理呢?

CURLOPT_FOLLOWLOCATION  有设置这个为1吗?

设上果真没了,
现在是 Bad Request (Invalid Number),这又是什么问题啊

你传入的数字不合法,看看是不是人家让输入数字,你输入其他内容了。

最好贴出你代码分析下。

经过分析发现,实际登陆地址应该是210.44.176.133,然后被重定向到这样的地址210.44.176.133/(0qus0s55gb1ojp45n2h0sr55)/Default2.aspx,中间括号里的是随机的每次都不同,现在那我应该怎么样去得到这重定向后的地址呢?
这是我写的方法
function curl_get_url(){		$cookie_file=tempnam('./ck','cookie');		$ch = curl_init("http://210.44.176.133");		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);		curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);		curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);		curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);		curl_setopt($ch, CURLOPT_MAXREDIRS, 10);		$data = curl_exec($ch);//运行curl		curl_close($ch);		return $data;		}

在 curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file); 前面加上
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

你用的是 get 方式,一般登录应该是 post 方式吧

你的地址是内网地址,无法测试
只能你自己慢慢调试了

这不是post的地方,是post之前的访问地址,post的时候没有提交cookie,学校是是通过记录那段随机地址来判断用户的应该是,现在就是想得到那个随机地址,这是你登陆页面,登陆后会跳转
210.44.176.133         --跳转-->  210.44.176.133 /(0qus0s55gb1ojp45n2h0sr55)/Default2.aspx
,然后在跳转之后的页面提交表单,可是不知道怎样得到这个地址唉。。。

用正则提取地址
