我目前遇到Node JS的问题,尝试与会话身份验证进行非常简单的聊天。 验证是正常的,但socket.emit事件(服务器端)未被socket.on事件(客户端)捕获。 这里的代码。 文件app.js:
app.get('/chat', [requireLogin], require('./lib/chat.js').chat(io));
文件lib / chat.js:
exports.chat = function(io){
return function(req,res) {
res.render('chat');
var ent = require('ent'); // same as htmlentities for PHP
io.sockets.on('connection', function (socket) {
var username = ent.encode(socket.handshake.username);
console.log('first_connection:'+username);
socket.emit('first_connection', username);
socket.on('connect_success', function() {
console.log('connect_success:'+username);
socket.broadcast.emit('join', username);
});
});
}
};
和客户方:
var sio = io.connect(), socket = sio.socket.of('/chat');
socket.on('first_connection', function (pseudo) {
console.log('first_connection is caught. Pseudo:'+pseudo);
document.title = pseudo + ' - ' + document.title;
socket.emit('connect_success');
});
我在客户端没有登录,登录服务器端:
first_connection:Test
debug - websocket writing 5:::{"name":"first_connection","args":["Test"]}
[编辑]以下是我的app.js文件中IO套接字的声明:
const
express = require('express'),
path = require('path'),
app = express(),
server = require('http').createServer(app),
io = require('socket.io').listen(server),
fs = require('fs'),
connect = require('express/node_modules/connect'),
cookie = require('express/node_modules/cookie')
;
答案 0 :(得分:0)
好的,我一步一步地回去重做同样的事情,现在效果很好! 我认为我的问题来自于我忘记了模块cookie的安装。
非常感谢! :)
