c＃FiddlerCore AutoResponder隧道连接失败

Posted 2021-05-03

所以我试图获得与Fiddler应用程序内的“AutoResponder”基本相同的功能。

我也需要这个离线工作。

网站我试图自动响应它HTTP（S）我输入代码，要求用户信任我已包含在下面的根证书，以使其在某种程度上相关。

            if (Fiddler.CertMaker.rootCertExists())
        {
            if (!Fiddler.CertMaker.rootCertIsTrusted())
            {
                MessageBox.Show(this, "You need to approve the Fiddler Root CA.", "First Time?");
                Fiddler.CertMaker.trustRootCert();
            }

        }
        else
        {
            Fiddler.CertMaker.createRootCert();
            if (!Fiddler.CertMaker.rootCertIsTrusted())
            {
                MessageBox.Show(this, "You need to approve the Fiddler Root CA.", "First Time?");
                Fiddler.CertMaker.trustRootCert();

            }
        }

        if (!Fiddler.CertMaker.rootCertIsTrusted())
        {
            MessageBox.Show(this, "Fiddler Root CA not Trusted.", "Error");
            this.Close();
        }

至于自动回复器（我非常肯定会导致问题）

 FiddlerApplication.Startup(8080, true, true, true);



        FiddlerApplication.BeforeRequest += delegate (Session session)
        {
            if (session.HTTPMethodIs("CONNECT")) { session.oFlags["X-ReplyWithTunnel"] = "Fake for HTTPS Tunnel"; return; }
            if (session.uriContains("https://google.com"))
            {
                session.bBufferResponse = true;
            }
        };

        FiddlerApplication.BeforeResponse += delegate (Session session)
        {
            session.utilDecodeResponse();
            session.LoadResponseFromFile("Google.txt");
        };

但是在运行此代码后，我无法访问任何HTTPS网站，即使在尝试AutoRespond的网站上也会收到错误“ERR_TUNNEL_CONNECTION_FAILED”。

答案

我设法修复它

            Fiddler.FiddlerApplication.BeforeRequest += new SessionStateHandler(FiddlerApplication_BeforeRequest);
                FiddlerApplication.Startup(8080 , true,true);

-

        private void FiddlerApplication_BeforeRequest(Session oSession)
    {
        FiddlerApplication.BeforeRequest += delegate (Session session)
        {

            Fiddler.FiddlerApplication.BeforeRequest += delegate (Fiddler.Session oS)
            {

                if (!oS.uriContains("google.com") && oSession.HTTPMethodIs("CONNECT")) { oSession.oFlags["X-ReplyWithTunnel"] = "Connect for real.."; }

                if (oS.uriContains("google.com") && oS.HTTPMethodIs("CONNECT")) { oS["x-replywithtunnel"] = "Fake tunnel..."; }
                if (oS.uriContains("https://google.com/"))
                {
                    oS.oFlags["x-replywithfile"] = AppDomain.CurrentDomain.BaseDirectory + "google.txt";
                }


                }
            };
        };
