使用socket.io桥接池php rest api

例如，我的php点公开了这些端点

[GET] /api/news --> [return] [ {id:1,title:'news1'},{id:1,title:'news1'} ];
[POST] /api/news?title=<string> --> [return] {id:NEW_ID,title:$title};

这将很好地工作，除了我必须集中每段时间来获取任何新消息，所以我认为类似socket.io的东西可以帮助我

我正在努力取得成功

用户连接到io

io在用户使用我的php api连接后发送所有新闻

当用户发布新消息时，他将其发送到io服务器，io将post请求转发到我的RESTAPI，并将结果返回给所有连接的用户

因此，我对前端的更改可能类似于

        var socket = io('http://localhost:3700');
        socket.on('news', function (data) {
            $timeout(()=>{$scope.news = data;});
        });
        socket.on('news_posted', function (data) {
            $timeout(()=>{$scope.news.push(data);});
        });
        $scope.post = function(title){
         socket.emit('post_news', { title: title });
        }

现在我不知道如何制作这样简单的服务器

var express = require("express");
var app = express();
var port = 3700;
var io = require('socket.io').listen(app.listen(port));

//setting CORS
app.all('*', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "http://localhost:8100");
  res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-type,Accept,X-Access-Token,X-Key,auth-client,auth-uid,auth-token');
  if (req.method == 'OPTIONS') {
    res.status(200).end();
  } else {
    next();
  }
});

io.sockets.on('connection', function (socket) {
      console.log('a user connected');
      ///BLOCK 1
      ///GET ALL POSTS FROM API AND EMIT news event BACK TO USER
      ///

      socket.on('new_post', function(msg){
        ///BLOCK 2
        ///POST title TO API AND EMIT BACK news_posted WITH THE RESPONSE
      });
});

难道redis的酒吧/酒吧套装不能更好地完成这项工作吗？@Federico这是什么？

var express = require("express");
var app = express();
var port = 3700;
var io = require('socket.io').listen(app.listen(port));

//setting CORS
app.all('*', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "http://localhost:8100");
  res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-type,Accept,X-Access-Token,X-Key,auth-client,auth-uid,auth-token');
  if (req.method == 'OPTIONS') {
    res.status(200).end();
  } else {
    next();
  }
});

io.sockets.on('connection', function (socket) {
      console.log('a user connected');
      ///BLOCK 1
      ///GET ALL POSTS FROM API AND EMIT news event BACK TO USER
      ///

      socket.on('new_post', function(msg){
        ///BLOCK 2
        ///POST title TO API AND EMIT BACK news_posted WITH THE RESPONSE
      });
});
