TypeError:io.connect不是函数 [英] TypeError: io.connect is not a function

问题描述

我正在关注使用节点js和socket.io进行的简单多人游戏的教程(

I am following a tutorial for a simple multiplayer game using node js and socket.io (http://rawkes.com/articles/creating-a-real-time-multiplayer-game-with-websockets-and-node.html) . I am having a problem when i am trying to connect to the socket server.I get an error saying TypeError: io.connect is not a function PS : i am a total beginner in node js and socket.io so please help me out.

var util = require("util");
io = require("socket.io"),
    Player = require("./Player").Player;
var socket, players;
function init(){
    players = [];

    socket = io.listen(8000);

    socket.configure(function() {
        socket.set("transports", ["websocket"]);
        socket.set("log level", 2);
    });

    setEventHandlers();

    socket = io.connect("http://localhost", {port: 8000, transports: ["websocket"]});

};

推荐答案

注意: socket = io.connect("http://localhost", {port: 8000, transports: ["websocket"]});这必须包含在通过脚本标记加载socket.io.js的客户端javascript文件中.

Note: socket = io.connect("http://localhost", {port: 8000, transports: ["websocket"]}); this has to be included in the client side javascript file where you load socket.io.js via script tag.

更改为此:

var util = require("util"),
    io = require("socket.io")({
      transports  : [ 'websocket' ]
    }),
    Player = require("./Player").Player,
    socket,
    players;

function init(){
    players = [];

    socket = io.listen(8000);

    setEventHandlers();

};
init();

注意 socket.io v1.0不支持以下版本，如果要这样做，则必须安装v0.9，请使用:$ npm install socket.io@0.9 -S

Note Below is not supported by socket.io v1.0 you have to install v0.9 if you want to do it that way, use: $ npm install socket.io@0.9 -S

socket.configure(function() {
    socket.set("transports", ["websocket"]);
    socket.set("log level", 2);
});

懒惰 socket.io v1.0 log-level选项已删除.因此，要记录日志，必须使用调试模块启动程序.

Looging socket.io v1.0 log-level option is removed. Thus for logging one has to start program using debug module.

1. 安装调试:npm install debug -S
2. 然后运行程序:DEBUG=* node entry_file.js

1. install debug: npm install debug -S
2. then run the program: DEBUG=* node entry_file.js
