角度-Socket.IO io未定义

Question

这里有一个建议： https://github.com/btford/angular-socket-io/issues/127

• make sure you have socket.io client library:

  bower install socket.io-client --save
  

这并没有解决我的问题，仍然出现了同样的错误。

• including in index.html:

  script src="lib/angular-socket-io/socket.js"
  

• in app.js

  angular.module('starter', ['ionic', 'starter.controllers', 'starter.services',       
   'starter.directives', 'btford.socket-io'])
  

• in services.js

  .factory('seatStatusSocket',function(socketFactory){ 
     var myIoSocket = io.connect(porturl); // io is not defined here, suddenly.
  

• It was working before, using a remote copy of the lib. When this error started, I changed index.html to link a local copy, as this remote version also received a Bad Gateway error (now fine, but still socket io is not defined as above).

被移除：

script src="http://chat.socket.io/socket.io/socket.io.js"

版本

socket.io@1.3.7 node_modules/socket.io
node --version
v0.12.7

你需要在index.html中包含：

script src="<bowerComponentPath>/socket.io-client/socket.io.js"

在此之前：

script src="<bowerComponentPath>/angular-socket-io/socket.js"

还有一点，这是必需的：

bower install socket.io-client --save

谢谢！就是这样！我以为我有两个相同的，所以当第一个socket.io-client出现Bad Gateway错误时，我将其删除了。当我更改为另一个可用的url版本后，它就可以工作了。 - mylord
