使用sails.sockets.join和sails.sockets.broadcast向客户端发送Sails.js不会向客户端返回信息 [英] Sails.js to client using sails.sockets.join and sails.sockets.broadcast doesn't return info to the client

问题描述

我正在尝试在客户端使用 Sails.js 和 Sails.io.js 创建一对一聊天.

I'm attempting to create a one to one chat using Sails.js and sails.io.js on the client side.

我可以让 io.socket.get 和 io.socket.post 工作，但我无法从 接收任何东西按照此处的说明，sails.sockets.broadcast 或 Model.publish:

I can get the io.socket.get and io.socket.post to work, but I haven't been able to receive anything from either sails.sockets.broadcast or Model.publish as instructed here:

使用 Sails.js 的个性化聊天

Sails.js + socket.io:发送从服务器到客户端的消息

服务器端代码:

UserController.js

UserController.js

module.exports = {
    listen: function(req, res) {
        console.log("about to join " + userId);
        sails.sockets.join(req.socket, req.param('userId'));
    }
};

MessageController.js

MessageController.js

// Some code to get userId and message model here

console.log("about to broadcast on " + userId);
sails.sockets.broadcast(userId, 'conversation_message', message); 

// Did not JSONify the message model, not sure if I need to?

来自:http://beta.sailsjs.org/#/documentation/reference/sails.sockets/sails.sockets.broadcast.html

客户端代码:

// Some code to get userId...

io.socket.get('/user/listen', {
    userId: userId
}, function() {
    io.socket.on('conversation_message', function(message) {
        console.log("we have a message");
    });
});

当我使用userId点击触发广播的路由时，没有任何内容发送到此客户端代码以记录我们有一条消息.有什么想法吗?

When I hit the route that triggers the broadcast with userId, nothing is sent to this client code to log we have a message. Any ideas?

我也尝试过 Model.subscribe/Model.publish 方法，但没有成功——同样的问题.

更新:listen 函数实际上并没有返回——正如有人在他们后来删除的评论中建议的那样.将 res.send(200); 添加到 listen 函数的末尾就足以让它工作了.

Update: The listen function doesn't actually return -- as someone suggested in a comment that they later deleted. Adding res.send(200); to the end of the listen function was enough to make it work.

如果那个人再次添加他们的评论作为答案，我会接受.

If that person would add their comment again as an answer I'll accept it.

推荐答案

(那是我.我认为我的评论可能不值得，因为我重读了你的帖子，你说你有工作，所以我认为我错了.我的评论是下面的大意，但我不记得逐字)

(That was me. I thought my comment might of been not worthwhile because i reread your post and you said you had the get working so I thought I was wrong. My comment was something to the effect below, but I don't remember verbatim)

您是否检查过以确保您确实在客户端收听中收到了响应?您实际上在整个代码中获得了哪些日志语句?将 console.log('get user listen') 或其他内容放在客户端 socket.get 中.

Have you checked to make sure the you are actually getting a response on the client-side listen? What log statements are you actually getting throughout your code? Put a console.log('get user listen') or something inside of the Client-side socket.get.
