socket.io - 在sails js socket.io中使用io.socket.get

Question

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 Controller 内的 join 函数永远不会通过套接字调用 io.socket.get('/join',...) 被触发。 Controller 中的 console.log 永远不会打印，也不会响应客户端。如果我通过 http 做同样的测试，它会触发 join 功能。我第一次使用套接字。谁能建议我在这里做错了什么？

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);
});

这只会在套接字连接后调用路由。希望这可以帮助!
