在sails js socket.io中使用io.socket.get

我正在使用带套接字io的sailsjs。帆的版本是0.10.5。我有以下套接字客户端进行测试:

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

// Instantiate the socket client (`io`)
// (for now, you must explicitly pass in the socket.io client when using this library from Node.js)
var io = sailsIOClient(socketIOClient);

// Set some options:
// (you have to specify the host and port of the Sails backend when using this library from Node.js)
io.sails.url = 'http://localhost:1337';
// ...

//Send a GET request to `http://localhost:1337/hello`:
io.socket.get('/join', function serverResponded (body, JWR) {
  // body === JWR.body
  console.log('Sails responded with: ', body);
  console.log('with headers: ', JWR.headers);
  console.log('and with status code: ', JWR.statusCode);

  // When you are finished with `io.socket`, or any other sockets you connect manually,
  // you should make sure and disconnect them, e.g.:
  //io.socket.disconnect();

  // (note that there is no callback argument to the `.disconnect` method)
});


io.socket.on('myroom', function(response){
  console.log(response);
});

在我的config / routes.js中,我有以下内容:

'get /join':'LayoutController.join'

在我的api / controller / LayoutController中,我有以下内容:

module.exports={

    join: function(req, res) {
        console.log('Inside Join');

        sails.sockets.join(req.socket,'myroom');
         res.json({message:'youve subscribed to a room'}); 
      }
    };

我遇到的问题是控制器内的join函数永远不会通过套接字调用io.socket.get('/ join',...)触发。控制器中的console.log从不打印,也没有响应客户端。如果我通过http进行相同的测试,它会触发join功能。我是第一次使用socket。任何人都可以在这里建议我做错了吗?

您可以在套接字与服务器建立连接后尝试运行get请求,因为它将通过套接字充当对sails服务器的虚拟请求。您可以将代码更改为以下内容:

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

var io = sailsIOClient(socketIOClient);

// Set some options:
// (you have to specify the host and port of the Sails backend when using this library from Node.js)
io.sails.url = 'http://localhost:1337';
// ...

//Send a GET request to `http://localhost:1337/hello`:
io.socket.on('connect', function(){
  io.socket.get('/join', function serverResponded (body, JWR) {
    // body === JWR.body
    console.log('Sails responded with: ', body);
    console.log('with headers: ', JWR.headers);
    console.log('and with status code: ', JWR.statusCode);

    // When you are finished with `io.socket`, or any other sockets you connect manually,
    // you should make sure and disconnect them, e.g.:
    //io.socket.disconnect();

    // (note that there is no callback argument to the `.disconnect` method)
  });
});


io.socket.on('myroom', function(response){
  console.log(response);
});

这将仅在套接字连接后调用路由。希望这有帮助!
