我的客户端有{-# LANGUAGE NumDecimals #-}
module Main where
import Data.Foldable (for_)
import System.IO
import GHC.Conc (setAllocationCounter,enableAllocationLimit)
main :: IO ()
main =
do setAllocationCounter 2e9
enableAllocationLimit
let writeToHandle h =
for_ ([1..]::[Integer])
(hPutStrLn h . show)
withFile "/dev/null" WriteMode writeToHandle
return ()
模块内的以下功能：
pieces我想要实现的目的是让服务器将上述数据发送到每个连接的套接字，发送方除外。就像各种教程和official documentation所说的那样，我在服务器端放了以下代码：
var nodeCoords = returnCoordinates(node),
sourceCoords = returnCoordinates(sourceNode),
board = require('board'),
player = board.table.cells[sourceCoords.x + 'x' + sourceCoords.y].piece.owner,
socket = io();
$(node).css({'border': '2px solid blue', 'width' : '58px', 'height': '58px'});
$(node).click(function(){
board.table.cells[sourceCoords.x + 'x' + sourceCoords.y].piece.move(nodeCoords.x, nodeCoords.y);
board.table.drawPieces();
board.table.resetBoard();
socket.emit('move', {'sourceCoords': sourceCoords, 'targetCoords': nodeCoords});
在我的客户端，在main requirejs文件中，事件 var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var http = require('http').Server(app);
var port = 8080;
var io = require('socket.io')(http);
var players = {
'white': null,
'black': null
}
app.use(express.static('public'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
io.on('connection', function(socket){
app.get('/login', function(req, res){
if(players.white === null){
players.white = 'taken';
res.send('white');
}else if(players.white !== null && players.black === null){
players.black = 'taken';
res.send('black');
io.emit('login', {msg: 'ready'});
}else{
res.send('Two players are currently playing game. Please try later.');
}
});
socket.on('move', function(data){
socket.broadcast.emit('turnReady', {'sourceCoords': data.sourceCoords, 'targetCoords': data.targetCoords});
});
socket.on('disconnect', function(){
console.log('User disconnected.');
});
})
http.listen(port, function(){
console.log('Server is listening on port ' + port + '.');
});
看起来像：
'turnReady'我在服务器端标志var socket = io();
$(document).ready(function() {
var player;
$.get('/login', function(data, status){
if(status === 'success'){
if(data === 'white' || data === 'black'){
player = data;
}else{
alert(data);
}
}
});
socket.on('login', function(data){
game(player);
});
socket.on('turnReady', function(data){
console.log('ready! ' + player);
board.table.cells[data.sourceCoords.x + 'x' + data.sourceCoords.y].piece.move(data.targetCoords.x, data.targetCoords.y);
board.table.drawPieces();
board.table.resetBoard();
board.table.startPlayerTurn(player);
});
});
上使用，所以我希望控制台准备就绪＆＃39;邮件将出现在发件人期望的每个连接的客户端上。然而，这并非如此，每个客户都会获得消息，甚至是发件人。我在这里做错了什么？
编辑：我提供了更多代码。感谢mido评论，我可以想到为什么会发生这种情况。我在件模块中创建了另一个套接字对象。这就是为什么广播没有按预期工作的原因？即使两个套接字都指向相同的默认命名空间吗？
