在Firefox的扩展JavaScript中是否有nsiClientSocket？ [英] Is there nsiClientSocket in firefox extension javascript?

问题描述

如何在Firefox中连接到JavaScript的端口？我可以打开端口和侦听（服务器端套接字），但我想要连接到服务器的客户端套接字（端口在Java中打开）。

解决方案

您使用 nsISocketTransportService.createTransport（）。像这样的应该工作：

  var transport = Components.classes [@ mozilla.org/ network / socket-transport-service; 1] 
 .getService（Components.interfaces.nsISocketTransportService）
 .createTransport（null，0，host，port，null）; 
 var stream = transport.openOutputStream（0，0，0）; 
 var data =test; 
 stream.write（data，data.length）; 
 stream.close（）;所有的连接事件都是异步发生的，所以为了监听传输事件，你需要调用  transport.setEventSink （） ：
 $ b 
  Components.utils.import（resource：// gre /modules/XPCOMUtils.jsm）; 
 Components.utils.import（resource：//gre/modules/Services.jsm）; 
 transport.setEventSink（
 onTransportStatus：function（transport，status，progress，progressMax）
 {
 ... 
}，
 QueryInterface：XPCOMUtils .generateQI（[Components.interfaces.nsITransportEventSync]）
}，Services.tm.currentThread）; 
  
供参考： nsITransportEventSink ， nsITransportEventSink状态码 
 
How to connect to a port from javascript in firefox extensions? I could able to open the port and listen (Server side socket), but I want the Client side socket which will connect to server (Port opened in java).
解决方案
You use nsISocketTransportService.createTransport(). Something like this should work:
var transport = Components.classes["@mozilla.org/network/socket-transport-service;1"]
                          .getService(Components.interfaces.nsISocketTransportService)
                          .createTransport(null, 0, host, port, null);
var stream = transport.openOutputStream(0, 0, 0);
var data = "test";
stream.write(data, data.length);
stream.close();
All connection events happen asynchronously so in order to listen to transport events you need to call transport.setEventSink():
Components.utils.import("resource://gre/modules/XPCOMUtils.jsm");
Components.utils.import("resource://gre/modules/Services.jsm");
transport.setEventSink({
  onTransportStatus: function(transport, status, progress, progressMax)
  {
    ...
  },
  QueryInterface: XPCOMUtils.generateQI([Components.interfaces.nsITransportEventSync])
}, Services.tm.currentThread);
For reference: nsITransportEventSink, nsITransportEventSink status codes
