分享求高手帮忙解决 c# 模拟登录带验证码 总提示验证码错误
c# 模拟登录带验证码 总提示验证码错误，这个网站以前没有加验证码的时候时可以正常模拟登录进去的。
这是以前的代码：
string str_ratk = "";
double dttick = this.cConvertDateTimeInt(System.DateTime.Now);
result = HttpHelper.GetHtml("http://www.plateno.com/p/nlogin.html?_=" + dttick.ToString() + "");
Regex rgeratk = new Regex(@"ratk""\s\w*=""\w*"">", RegexOptions.Compiled); // ratk"\s\w*="\w*">
Match mratk = rgeratk.Match(result);
str_ratk = mratk.Groups[0].ToString().Trim();
str_ratk = cGetStringBetween(str_ratk, "value=\"", "\">");
result = "";
postData = "fromType=0&username=13535127593&password=a111111&atk=" + str_ratk.Trim() + "&j_expiredays=0&passwordType=0";
result = HttpHelper.GetHtml("http://www.plateno.com/ajax_authentication", postData, true, HttpHelper.CookieContainer);
网站加了验证码后参考了一些网友的做法，但总是提示 “验证码错误”

你要先用HttpRequest访问取验证码地址,然后用这个Cookies取登录的页面，然后取到Hidden里的特殊值与Cookies
最后把上面的Cookies一起打包发送请求就可以了。

我的大概思路也是这样子，但还是不行，能不能把你的类发一份给我参考一下？感谢！

这种网站没这么简单的。
去把head 什么的都弄弄。
Cookie 弄成stringCookie 一个个取 。

加了你的类，还是验证码不正确

这个 atk 的值我是为了调试方便固定了一下，实际上是每次都有去取这个atk的值，但把这个atk的值加上去后还是报验证码不正确，在帖子的内容里有加atk的，但不知道为什么总是不成功

sc=new SinaCookie();

doGetImg("http://www.plateno.com/imageToken?id=lgCheckcode&r=0.6810257183387876",sc);//验证码获取
dopost。。。。登录
类似这样。
如果你有我的那些类。 sc传进去 Cookie会自动更新。。。

获取验证码时有时会返回cookie,提交的时候要带上.
代码好乱,看的头疼

用fiddler抓包比较几次，看看post的字符串构造对不对
如果构造正确，那么就检查headers，看看有没有防盗链处理

一看就知道 atk 是验证码相关。 你atk 是固定了。 你必须先去登录页面采集这个atk
然后 去获取验证码。
然后 提交。

没打算用程序去识别验证码，我是想把验证码取到后显示出来，然后用手工输入验证吗, 为什么这个网站总是提示验证码不正确？我试了一下其它的网站是可以的，不知道这个网站为什么不行

验证码不会识别的话，那肯定是错误的。除非网站给留后门
