c# - Fiddler 和 .Net 3.5 SSL 错误。在 .Net 4.0 中工作正常

Question

首先，网站和帖子。

https://saplic.receita.pb.gov.br/sintegra/SINf_ConsultaSintegra.jsp 填写字段CNPJ，值为例如34151100004209。

在 Chrome 和 .Net 4.0 Httpwebrequest 中运行良好。但我无法在 fiddler 中进行调试，也无法使其在 .Net 3.5 上运行

我已经在用了

System.Net.ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(customXertificateValidation);
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3;
System.Net.ServicePointManager.Expect100Continue = false;

这让我发疯。任何帮助将不胜感激 为了让事情更清楚，我有一个问题发生在 2 个不同的地方(Fiddler 和 .net 3.5)

我尝试运行的代码是。

    CookieContainer CookCon =  new CookieContainer();
    HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("http://sintegra.receita.pb.gov.br/sintegra/sintegra.asp?estado=pb");
    Request.Timeout = Configuration.TimeOut;
    Request.Proxy = Configuration.Proxy;
    Request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36";
    Request.Headers.Add("Accept-Encoding", "gzip, deflate");
    Request.CookieContainer = new CookieContainer();
    using (HttpWebResponse Response = Request.GetResponse() as HttpWebResponse)
    {
        foreach (Cookie C in Response.Cookies)
        {
            CookCon.Add(C);
        }
        Response.Close();
    }

    HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://saplic.receita.pb.gov.br/sintegra/");
    Request.Referer = "http://sintegra.receita.pb.gov.br/sintegra/sintegra.asp?estado=pb";
    Request.Headers.Add("X-DevTools-Emulate-Network-Conditions-Client-Id", "C5E5561B-11F5-4D9E-A9D4-54A18E660D11");
    Request.CookieContainer = CookCon;
    Request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
    Request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.103 Safari/537.36";

    string HTML = "";

    string Encoding = "ISO-8859-1";
    Request.Timeout = 20000;

    Request.Headers.Add("Accept-Encoding", "gzip, deflate");
    using (HttpWebResponse Response = Request.GetResponse() as HttpWebResponse)
    {
        Stream S = Response.GetResponseStream();
        if (Response.ContentEncoding.ToLower().Contains("gzip"))
        {
            S = new GZipStream(S, CompressionMode.Decompress);
            using (System.IO.StreamReader ResStream = new StreamReader(S, System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        else if (Response.ContentEncoding.ToLower().Contains("deflate"))
        {
            S = new DeflateStream(S, CompressionMode.Decompress);
            using (System.IO.StreamReader ResStream = new StreamReader(S, System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        else
        {
            using (System.IO.StreamReader ResStream = new StreamReader(Response.GetResponseStream(), System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        S.Close();
        S.Dispose();
        Response.Close();
    }

我遇到的错误是当我尝试发帖时出现“unexpeted EOF”异常(上面代码的 GetResponse 部分)。 如果我尝试在打开 Fiddler 的情况下在 Chrome 上浏览网站，它不会向北返回，只是保持保持、保持、保持，什么也没有。

如果我将相同的代码复制到一个新的 4.0 项目中，它可以毫无问题地运行。 如果不清楚，请提出疑问，我尽量说清楚。

Answer 1

由于没有人提供帮助，我只是使用 .net 4.0 框架制作了一个网络服务，并从 3.5 应用程序调用它。

仍然不知道为什么会发生这种情况..
