要的Android Node.js的通信 [英] Android to node.js communication
问题描述
我看到有几个类似的线程，但我找不到我的答案。
我正在和Android应用程序中，我想使用节点服务器进行实时通信。
我真的不能得到这个工作。
也许我做很多很多事情错了，但我想试着去理解。
我的服务器很简单，只要
VAR HTTP =要求（HTTP），
IO =需要（'socket.io），
服务器= http.createServer（功能（REQ，RES）{
res.writeHead（200，{内容类型：text / html的'}）;
res.end（':)'）;
}）;
server.listen（8080）;
VAR插座= io.listen（服务器）;
socket.on（'连接'，功能（客户端）{
client.send（你好）;
的console.log（接！）;
}）;
和这个作品......我想这与一个web应用程序，我可以连接。
但我不能用java ..
我想 kryonet 但我得到一个例外，如连接超时，但在注册
我想 weberknecht 我得到一个错误在创建套接字WS： //184.xxxxxx:8080
我想 TooTallNate ，没有运气，它只是调用的OnClose方法。
我想 jWebSocket 但我无法得到它的工作...
所以，我在这里，寻求帮助，有没有人知道如何完成这件事？任何建议？
P.S。 对于TooTallNate我使用的是这样的：
净净=新的网络化（新的URI（WS：//184.xxxxxx：8080），WebSocketDraft.DRAFT76 ）;
也许这个问题会在这里？
更新： 我处理了这个！良好的睡眠我有这个想法，我使用socket.io，糟糕的主意......我现在用的节点的WebSocket服务器与 weberknecht 。服务器看起来是这样的：
变种WS =要求（WebSocket的服务器）;
VAR服务器= ws.createServer（）;
server.addListener（连接，功能（客户端）{
的console.log（新的连接）;
client.send（AAAAAA）;
client.addListener（信息，函数（MSG）{
}）;
}）;
server.listen（8080）;
和客户端：
尝试{
URI URL =新的URI（WS：//184.106.69.64：8080 /）;
的WebSocket的WebSocket =新WebSocketConnection（URL）;
websocket.setEventHandler（新WebSocketEventHandler（）{
公共无效的OnOpen（）{
的System.out.println（ - 开）;
}
公共无效的onMessage（WebSocketMessage消息）{
的System.out.println（ - 接收到的消息：+ message.getText（））;
}
公共无效的OnClose（）{
的System.out.println（ - 关闭）;
}
}）;
websocket.connect（）;
websocket.send（世界你好）;
}
赶上（WebSocketException WSE）{
wse.printStackTrace（）;
}
赶上（的URISyntaxException使用）{
use.printStackTrace（）;
}
我节点的WebSocket服务器（NWS）的作者，我是pretty的确认工作的原因为节点的WebSocket服务器和socket.io不，是由于每个的执行。 NWS将自动谈判的权利草案使用，它也有一个希望90-100％，符合76和75的草稿。
至于socket.io，我不能评论太多，但最后我一看，这是WebSocket的执行实施相当差。
我目前工作的一个项目，当时称作节点的WebSocket协议的那一刻，这将是能够使用socket.io，王菲等为他们提供一个非常可靠的，合规的WebSocket实现。这也将替换节点的WebSocket服务器的当前实施2.0.0版本。
作为一个侧面说明，如果你不想承载自己的WebSocket的服务器，你可以看看使用Pusher.com，谁是真正我的雇主。
[更新]至于的WebSockets是否是最合适的技术选择，为您的应用，是数据和交互应用需要什么类型的问题。在移动设备上，它可能是最好使用类似urbanairship或notifio如果你只是发送推送通知。
问候， Micheil史密斯
I saw there are a couple of similar threads but i could not find my answer.
I'm making and android app, an i want to use node as server for real time communication.
I really cannot get this to work.
Probably I'm making many many things wrong but i like to try to understand.
My server is as simple as
var http = require('http'),
io = require('socket.io'),
server = http.createServer(function(req, res){
res.writeHead(200, {'Content-Type': 'text/html'});
res.end(':)');
});
server.listen(8080);
var socket = io.listen(server);
socket.on('connection', function(client){
client.send("hello");
console.log("connected!");
});
and this works... I tried this with a web app and I can connect.
But I can't with java..
I tried kryonet but I get an exception like "connected but timeout on registration"
I tried weberknecht I get a "error while creating socket to ws://184.xxxxxx:8080"
I tried TooTallNate, no luck, it just call onClose method.
I tried jWebSocket but I couldn't get it to work...
So I'm here, asking for help, does anyone knows how to get this done? any suggestion?
P.S. for TooTallNate I'm using something like this:
Net net = new Net(new URI("ws://184.xxxxxx:8080"),WebSocketDraft.DRAFT76);
might the problem be here?
UPDATE: I handled this! after a good sleep I had the idea, I was using socket.io, bad idea... now I use Node Websocket Server with weberknecht. The server looks like this:
var ws = require("websocket-server");
var server = ws.createServer();
server.addListener("connection", function(client){
console.log("new connection");
client.send("aaaaaa");
client.addListener("message", function(msg){
});
});
server.listen(8080);
and the client:
try {
URI url = new URI("ws://184.106.69.64:8080/");
WebSocket websocket = new WebSocketConnection(url);
websocket.setEventHandler(new WebSocketEventHandler() {
public void onOpen(){
System.out.println("--open");
}
public void onMessage(WebSocketMessage message){
System.out.println("--received message: " + message.getText());
}
public void onClose(){
System.out.println("--close");
}
});
websocket.connect();
websocket.send("hello world");
}
catch (WebSocketException wse) {
wse.printStackTrace();
}
catch (URISyntaxException use) {
use.printStackTrace();
}
I'm the author of node-websocket-server (nws), and I'm pretty sure the reason for node-websocket-server working and socket.io not, is due to the implementation of each. NWS will auto negotiate the right draft to use, and it also has a hopefully 90-100% compliance with the drafts of 76 and 75.
As for socket.io, I can't comment too much, but the last I looked, it's websocket implementation was rather poorly implemented.
I'm currently working on a project at the moment called node-websocket-protocol, which will be able to be used by socket.io, faye, etc as to provide them with a really reliable and compliant websocket implementation. This will also replace the current implementation in node-websocket-server in version 2.0.0.
As a side note, if you'd rather not host your own websocket server, you could look at using Pusher.com, who're actually my employers.
[Update] As for whether websockets are the most appropriate technology choice for your application, is a matter of what type of data and interaction your application needs. On a mobile device, it may be best to use something like urbanairship or notifio if you're just sending push notifications.
