在sails js socket.io中使用io.socket.get

我正在使用sailsjs和socketio。sails版本是0.10.5。我有以下用于测试的套接字客户端：

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'

module.exports={

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

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

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);
});

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

'get /join':'LayoutController.join'

module.exports={

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

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

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);
});

我遇到的问题是，控制器中的join函数永远不会通过套接字调用io.socket.get（'/join'，…）触发。console.log-in控制器从不打印，也不会向客户端返回响应。如果我通过http执行相同的测试，它将触发join函数。我第一次使用socket。任何人都可以建议我在这里做错了什么吗？

您可以尝试在套接字与服务器建立连接后运行get请求，因为它将作为通过套接字向sails服务器发出的虚拟请求。您可以将代码更改为以下内容：

'get /join':'LayoutController.join'

module.exports={

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

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

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

您将套接字客户端的代码放在哪里？您是从单独的SAIL服务器还是节点服务器运行它？它看起来不像是要在浏览器中运行的代码，除非您使用的是

browserify

…谢谢您的回复。我使用node单独运行socketclient代码。最终会有一个客户。不过，这是我的测试。问题似乎出在我的本地机器上。我在另一台服务器上得到了io.socket.get（…）的响应。另一个不相关的问题是，sails的socket.io是否与IIS 7.5兼容？socket.io不是由sails的开发人员维护的，但通过谷歌搜索“socket.io IIS”应该可以让您有所了解。如果您能找出本地计算机的问题所在，我建议您更改标题以反映您的系统（例如“Socket request not working with Windows Server 2012”），然后发布答案，以便其他有相同问题的用户可以在此处找到帮助！
