Question

我在grunt-express上遇到socket.io的问题。

我尝试了很多方法，但它仍然没有用。当我使用socket.io运行express而没有grunt时，我没有遇到这个问题。我在server.js和index.html中有相同的代码。

浏览器控制台出错：

GET http://localhost:9000/socket.io/socket.io.js 
angular.js:11655 ReferenceError: io is not defined
    at new <anonymous> (http://localhost:9000/scripts/controller.js:13:18)

    at invokeLinkFn (http://localhost:9000/bower_components/angular/angular.js:8258:9) <div class="pages ng-scope" ui-view="">

这是来自server.js的代码：

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

app.use(express.static(path.join(__dirname, './app/')));

index.html中的

：

<script src="/socket.io/socket.io.js"></script>

脚本/ controller.js

app.factory('socket', function() {
    var socket = io();
    return socket;
})

app.controller('loginCtrl', function($scope, socket) {
    ...
});

和我的Gruntfile.js：

connect: {
  options: {
    port: 9000,
    socketio: true,
    open: true,
    livereload: 35729,
    // Change this to '0.0.0.0' to access the server from outside
    hostname: 'localhost'
  },

...

express: {
    options: {
        port: 3000,
        delay: 500,
        background: true
    },
    dev: {
      options: {
        script: '<%= config.app %>/server/server.js'
      }
    }
},

Socket.io - ReferenceError：在Grunt-express上没有定义io
