在sails的bootstrap.js文件中添加websocket "put“请求:找不到io

Question

我需要从sails中的bootstrap.js文件调用一个套接字请求。bootstrap.js文件包含一些代码，用于检查某个游戏引擎是否更新了某个文件。如果是这样的话，它需要通过套接字向某个已定义的名为“/update”的路由发送一条包含一些更新数据的消息……例如：

io.socket.put('/update', {history:{sessions:[1,2,3,4]}},function gotResponse(body, response) {
    console.log('Server sending request ot server ');
})

问题是，它告诉我，io不被识别。我尝试为sails.io.js和socket.io-client安装npm，然后写道：

var io = require('sails.io.js')( require('socket.io-client') );

在顶端。不幸的是，它给出了以下错误消息：

C:\Users\Evolver\Documents\programming\pipegame\game6\node_modules\socket.io-client\lib\url.js:29
if (null == uri) uri = loc.protocol + '//' + loc.host;
                        ^

有什么想法吗？

好的。一旦为socket.io-client和sails.io.js完成了npm安装，它现在就可以工作了，如果我完全执行以下操作的话：

var socketIOClient = require('socket.io-client');
var sailsIOClient = require('sails.io.js');

// Instantiate the socket client (`io`)
var io = sailsIOClient(socketIOClient);
io.sails.url = 'http://localhost:1337';

// then I send something via my socket
io.socket.put('/update', {history:{sessions:[1,2,3,4]}},function gotResponse(body, response) {
                    console.log('Server sending request ot server ');
                })
