我正在尝试使用 Jabber.net(c#/Mono) 连接到 facebook 聊天。我正在使用的代码是这样的：

    static ManualResetEvent done = new ManualResetEvent(false);

    const bool VERBOSE = true;
    const string TARGET = "friends_username@chat.facebook.com";

    void Start () 
    {

        JabberClient j = new JabberClient();

        j.User = "my_facebook_alias";  //Later to be removed
        j.Server = "chat.facebook.com"; 
        j.Port = 5222;
        j.NetworkHost = "chat.facebook.com";
        j.AutoStartCompression = true;
        j.KeepAlive = 30F;
        j.AutoStartTLS = false;
        j.AutoStartCompression = true;
        j.PlaintextAuth = true;
        j.Password = "my_facebook_password";  //Later to be removed
        j.RequiresSASL = true;
        j.LocalCertificate = null;
        // don't do extra stuff, please.
        j.AutoPresence = false;
        j.AutoRoster = true;
        j.AutoReconnect = -1;

        j.OnInvalidCertificate += new System.Net.Security.RemoteCertificateValidationCallback(j_OnInvalidCertificate);

        // listen for errors.  Always do this!
        j.OnError += new bedrock.ExceptionHandler(j_OnError);

        // what to do when login completes
        j.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate);

        // listen for XMPP wire protocol
        if (VERBOSE)
        {
            j.OnReadText += new bedrock.TextHandler(j_OnReadText);
            j.OnWriteText += new bedrock.TextHandler(j_OnWriteText);
        }

        // Set everything in motion
        j.Connect();

        // wait until sending a message is complete
        done.WaitOne();

        // logout cleanly
        j.Close();
    }

    static void j_OnWriteText(object sender, string txt)
    {
        if (txt == " ") return;  // ignore keep-alive spaces
        Console.WriteLine("SEND: " + txt);
    }

    static void j_OnReadText(object sender, string txt)
    {
        if (txt == " ") return;  // ignore keep-alive spaces
        Console.WriteLine("RECV: " + txt);
    }

    static void j_OnAuthenticate(object sender)
    {
        Debug.Log ("OnAuth...");
        // Sender is always the JabberClient.
        JabberClient j = (JabberClient)sender;
        j.Message(TARGET, "My test message!!!");

        // Finished sending.  Shut down.
        done.Set();
    }

    static void j_OnError(object sender, Exception ex)
    {
        // There was an error!
        Console.WriteLine("Error: " + ex.ToString());
        Debug.Log ("Error: "+ex.ToString());
        // Shut down.
        done.Set();
    }

    bool j_OnInvalidCertificate(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
    {
        Debug.Log("Invalid certificate "+sslPolicyErrors.ToString() +" : "+certificate.ToString(true));

        return true;
    }

我到了 j_OnAuthenticate，这很好。它使用我的 ID/密码，因为将密码更改为其他内容会出现错误。但是我确实想使用 X-FACEBOOK-PLATFORM SASL 机制来登录而不保存用户 ID/密码。

在 MatriX XMPP 中有一个 OnBeforeSasl 委托，其中自定义方法可以设置所需的 facebook Sasl 属性（如 facebook 应用程序 ID、应用程序密码和访问令牌）。但是 Jabber.net 中没有这样的代表！

Jabber.net 上没有 SASL 支持吗？或者你是怎么设置的？

jabber-net 中支持 SASL，但不支持 X-FACEBOOK-PLATFORM SASL 机制。如果你想使用这个机制，你必须通过添加这个 SASL 机制来扩展 jabber-net。

Facebook 正在关闭 XMPP 连接。这可能与您在 Authenticate 事件中发送的消息有关。尝试在 jabber-net 发送您的初始状态后或在您获得名册后发送您的消息。
