Question

如何从网页获取验证码并显示在窗口控件上

Answer 1

我获取验证码仅在短信上有显示，需关闭该网页再看短信，再返回原网页就超时了。我应怎么在网页的眉头看到验证码呢？

Answer 2

/// <summary>
/// 获取验证码方法
/// </summary>
public Bitmap LoadImg(string ImageUrl)
{
try
{
HttpWebRequest wrq = (HttpWebRequest)WebRequest.Create(ImageUrl);//请求的URL
wrq.Method = "GET";
wrq.Timeout = 5000;
wrq.ContentType = "application/x-www-form-urlencoded";

//获取返回资源
HttpWebResponse response = (HttpWebResponse)wrq.GetResponse();

//获取流
Bitmap bt = Bitmap.FromStream(response.GetResponseStream()) as Bitmap;
return bt;
}
catch
{
return null;
}
return null;
}

调用这个应该就可以了 参数是图片地址
