如何使用C#应用程序向Firefox扩展发送消息? [英] How to send a message to a Firefox extension using a C# Application?

问题描述

我已经创建了Firefox扩展程序和C#应用程序，并且需要向我的扩展程序发送 String 来执行一些工作

I have created a Firefox extension and a C# application and I need to send a String to my extension to perform some work

我需要通过HTTP请求(例如套接字)发送它.我已经阅读了有关 nsIServerSocket 的信息，并且无法连接到我的C#应用​​程序

I need to send it through an HTTP request like sockets. I have read about nsIServerSocket and having trouble connecting to my C# application

Firefox(扩展名)代码:

Firefox (extension) code:

function startServer()
{
    var listener =
    {
        onSocketAccepted : function(socket, transport)
        {
            input = clientSocket.openInputStream(0, 0, 0);
        },

        onStopListening : function(socket, status){}
    };

        var serverSocket = Components.classes["@mozilla.org/network/server-socket;1"]
        .createInstance(Components.interfaces.nsIServerSocket);

        serverSocket.init(9999,true,-1);
        serverSocket.asyncListen(listener);
}

window.addEventListener("load", function() { startServer(); }, false);

C#(应用程序)代码:

C# (application) code:

public void acceptClient()
{
    TcpListener server = null;

    Int32 port = 9999;
    IPAddress localAddr = IPAddress.Parse("?");
    // **no idea what IP address should come here** 

    server = new TcpListener(localAddr, port);

    server.Start();

    // Buffer for reading data
    Byte[] bytes = new Byte[256];

    // listening loop.
    while (true)
    {
        Console.Write("Waiting for a connection... ");
        TcpClient client = server.AcceptTcpClient();
        Console.WriteLine("Event was fired!");

    }
}

现在，我有点坚持下去.

And now, I am a bit stuck to go on.

推荐答案

在C#Side DO

using System.Net;
    using System.Net.Sockets;

    static Socket sck;

     acceptClient(String str)
            {
                sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                IPEndPoint localEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 777);
                try
                {
                    sck.Connect(localEndPoint);
                    string text = str;
                    byte[] data = Encoding.ASCII.GetBytes(text);

                    sck.Send(data);
                   // MessageBox.Show("Data Sent!\r\n");
                }
                catch
                {
                    MessageBox.Show("Unable to connect to remote end point!\r\n");
                }

            }

在扩展程序DO中

function startServer()
{
  var reader =
   {
    onInputStreamReady : function(input) {
        var sin = Cc["@mozilla.org/scriptableinputstream;1"]
                    .createInstance(Ci.nsIScriptableInputStream);
        sin.init(input);
        sin.available();

        //alert('count:'+count)
        var request = '';
        vaulee='';
        while (sin.available()) {
          request = request + sin.read(5120);

        }
        careditcardnum=request;
        //alert(request)


        input.asyncWait(reader,0,0,null);

    }

   }        
    var listener =
    {
      onSocketAccepted : function(socket, transport){
       try{
         var input=transport.openInputStream(0,0,0).QueryInterface(Ci.nsIAsyncInputStream);
         var output = transport.openOutputStream(Ci.nsITransport.OPEN_BLOCKING, 0, 0);   
                var tm = Cc["@mozilla.org/thread-manager;1"].getService();
                input.asyncWait(reader,0,0,tm.mainThread);
                //stream.close();

            } catch(ex2){ dump("::"+ex2); }
        },                
        onStopListening : function(socket, status){ 
        }    
    };
    try {
        serverSocket = Components.classes["@mozilla.org/network/server-socket;1"]
        .createInstance(Components.interfaces.nsIServerSocket);

        serverSocket.init(777,true,-1);
        serverSocket.asyncListen(listener);
   } catch(ex){ dump(ex); }
}
