在浏览器中打开,可以看到内容,但是用post或者get方法就返回空(这两个方法应该没有问题,其他网页可以返回结果)。
用webbrowser也看不到内容。

这个是抓包得到的数据,直接用WebRequest 也不行,但是我用GetHtml可以获取其他网页的数据
public static string GetHtml(string URL)
{
WebRequest wrt;
wrt = WebRequest.Create(URL);
wrt.Credentials = CredentialCache.DefaultCredentials;
WebResponse wrp;
wrp = wrt.GetResponse();
string html = new StreamReader(wrp.GetResponseStream(), Encoding.UTF8).ReadToEnd();
return html;
}
public static string GetHtml(string URL) { WebRequest wrt; wrt = WebRequest.Create(URL); wrt.Headers.Add("Cookie:JSESSIONID=B9543CFB75688E73A34D4C1E8A9F7BD0##########"); wrt.Credentials = CredentialCache.DefaultCredentials; WebResponse wrp; wrp = wrt.GetResponse(); string html = new StreamReader(wrp.GetResponseStream(), Encoding.UTF8).ReadToEnd(); return html; }
把浏览器中打开时发送的头信息抄下来
在发http请求时模拟的发送这些头信息
