集成node.js，socket.io和php网页 [英] Integrating node.js, socket.io and php web page

问题描述

我将把我的php网页与node.js和socket.io集成在一起. 客户端可以连接到node.js服务器文件，但是socket.emit函数无法从客户端到服务器或返回. 这是我的nodeClient.js文件:

I am going to integrate my php web page with node.js and socket.io. The client can connect to node.js server file but the socket.emit function does not work from client to the server or return. Here is my nodeClient.js file:

var socket = io.connect( 'http://192.168.0.10:8080/index3.php' );

$( "#messageForm" ).submit( function() {
    var nameVal = $( "#nameInput" ).val();
    var msg = $( "#messageInput" ).val();

socket.emit( 'message', { name: nameVal, message: msg });

// Ajax call for saving datas
$.ajax({
    url: "./ajax/insertNewMessage.php",
    type: "POST",
    data: { name: nameVal, message: msg },
    success: function(data) {
    }
});

return false;
});

socket.on( 'new message', function( data ) {
    var actualContent = $( "#messages" ).html();
    var newMsgContent = '<li> <strong>' + data.name + '</strong> : ' + data.message + '</li>';
    var content = newMsgContent + actualContent;

    $( "#messages" ).append(newMsgContent);
});

这是nodeServer.js文件:

here is the nodeServer.js file:

var socket = require( 'socket.io' );
var express = require( 'express' );
var http = require( 'http' );

var app = express();
var server = http.createServer( app );
var io = socket.listen( server );

io.sockets.on( 'connection', function( client ) {
console.log( "New client !");

client.on( 'message', function( data ) {
    console.log( 'Message received ' + data.name + ":" + data.message );

    //client.broadcast.emit( 'message', { name: data.name, message: data.message } );
    io.sockets.emit( 'new message', { name: data.name, message: data.message } );
});
});

server.listen( 8080, function(){
  console.log('listening on *:8080');
});

ajax可以将数据存储在mysql中.每个连接的客户端都被识别为新客户端！".但是客户端和服务器之间没有消息通信.我的代码可能是什么问题.

the ajax works to store the data in mysql. Each client connected is recognized "New Client!". But no message communicating between client and server. What could be the problem in my code.

推荐答案

更正JSON语法，而不是在客户端编写:

correct your JSON syntax instead of writing on client side:

socket.emit( 'message', { name: nameVal, message: msg });

写

socket.emit( 'message', { "name": nameVal, "message": msg });

与服务器端相同，在json对象中写入值名称时，您实际上错过了双引号

same on server side you actually missed the double quotes while writing the name of value in json object
