通过firefox tcp socket.send（）发送的数据不能返回直到关闭套接字 [英] data send by firefox tcp socket.send() can't retrive until close the socket

问题描述

我尝试从Firefox发送一些数据到Java桌面应用程序，所以我的Java类作为服务器工作，Firefox脚本作为客户端工作。当我使用另一个Java类 client.java 数据成功发送到 server.java 如何使用这个firefox脚本发送数据，它实际上连接到服务器。 send（text）; 不能实时工作.i意思是当我关闭套接字时，服务器显示收到的数据 socket.close（）; 。但是我知道 server.java 代码没有问题。

这不起作用

  setTimeout（function（）{socket.send（i'm firefox）;}，5000）; //因为套接字尚未关闭
  

这项工作

  setTimeout（function（）{socket.send（i'm firefox）;}，5000）; 
 setTimeout（function（）{socket.close（）;}，6000）; 
  

但我真的不想关闭套接字，因为我想发送大量数据一个。
$ b $ p这里是在scratchpad测试完整的代码[-browser]

  var tcpSocket = Cc [@ mozilla.org/tcp-socket;1\"].createInstance(Ci.nsIDOMTCPSocket）; 
 var socket = tcpSocket.open（127.0.0.1，5000）; 
 $ b setTimeout（function（）{socket.send（i'm firefox）;}，5000）; 
 //setTimeout(function(){socket.close();},8000);//我是firefox文本，当运行这个行/关闭套接字时，由服务器检索。 
  

我认为java代码并不重要，但

解决方案

它实际上工作。您正在收到您的数据，但您目前正在等待新的一行打印收到的消息： = in.readLine（））！= null）{
System.out.println（Server：+ inputLine）;
out.println（inputLine）;

if（inputLine.equals（Bye。））{
break;




$ b $ p
$ b当前只有在关闭套接字时才会发生。只要在消息的最后添加一行，它就可以按预期工作：

  var tcpSocket = Cc [@ mozilla .ORG / TCP套接字; 1\" ]的createInstance（Ci.nsIDOMTCPSocket）; 
 var socket = tcpSocket.open（127.0.0.1，5000）; 
 
函数sendMessage（msg）{
 socket.send（msg +\\\
）; 
 
 
 setTimeout（function（）{
 sendMessage（hi mark）; 
}，3000）; 
 
 setTimeout（function（）{
 sendMessage（hi johnny）; 
}，5000）; 
  

I'm trying to send some data from Firefox to java desktop application .so my java class work as a server and Firefox script work as a client .when i test it using another java class which is client.java data successfully sent to server.java how ever when i use this firefox script to send data ,it actually connect to the server .but send("text"); doesn't work realtime .i mean sever shows received data when i close the socket socket.close(); . but i know there is no problem with server.java code.

this doesn't work

setTimeout(function(){socket.send("i'm firefox");},5000); // because socket isn't closed yet

this work

setTimeout(function(){socket.send("i'm firefox");},5000);
setTimeout(function(){socket.close();},6000); 

but i really don't want to close the socket because i want to send lot of data one by one.

here is the complete code tested on scratchpad [-browser]

var tcpSocket = Cc["@mozilla.org/tcp-socket;1"].createInstance(Ci.nsIDOMTCPSocket);
var socket = tcpSocket.open("127.0.0.1", 5000);

setTimeout(function(){socket.send("i'm firefox");},5000);
//setTimeout(function(){socket.close();},8000);// i'm firefox text retrieve by server when run this line / when close the socket.

i think java code isn't important.but here it is.

I'm asking why do i need to close the socket to send data ? and how can i send data without close the socket ?

---

update

i made a Gif to show my problem here you can see data not sending real time but when socket is closed all the data flushed .

解决方案

It's actually working. Your data is being received, but you're currently waiting for a new line to print your received messages:

while ((inputLine = in.readLine()) != null) {
    System.out.println("Server: " + inputLine);
    out.println(inputLine);

    if (inputLine.equals("Bye.")) {
        break;
    }
}

Which currently only happens when you close the socket. Just add a new line at the end of your messages and it will work as expected:

var tcpSocket = Cc["@mozilla.org/tcp-socket;1"].createInstance(Ci.nsIDOMTCPSocket);
var socket    = tcpSocket.open("127.0.0.1", 5000);

function sendMessage(msg){
    socket.send(msg + "\n");
}

setTimeout(function(){
    sendMessage("hi mark");
},3000);

setTimeout(function(){
    sendMessage("hi johnny");
},5000);
