Open it in the browser and you can see the content, but using the post or get method returns empty (these two methods should not problem, other web pages can return results).
You can’t see the content even with webbrowser.

This is the data obtained by capturing the packet. Direct use of WebRequest will not work, but I can use GetHtml to obtain data from other web pages

public static string GetHtml(string URL)
{
WebRequest wrt;
wrt = WebRequest.Create(URL);
wrt.Credentials = Credential Cache.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;        }

Copy the header information sent when the browser is opened

Simulate sending these header information when making an http request
