如何在快速路由中使用socket.io？

高阶函数呢？

exports.cmp = function(io) {  return function(req, res){    var product_id = req.body.product_id;    var bid = req.body.bid.split('b')[1];    io.sockets.emit("bidSuccess", {product_id: product_id, bid: bid});    response.json(200, {message: "Message received!"});      }};

然后

app.post('/cmp', routes.cmp(io));

作为另一种选择，有时我会将路线的格式设置为以下格式：

var routes = require('./routes/routes');routes(app, io);

然后定义

routes

module.exports = function(app, io) {  app.post('/cmp', function(req, res){    var product_id = req.body.product_id;    var bid = req.body.bid.split('b')[1];    io.sockets.emit("bidSuccess", {product_id: product_id, bid: bid});    response.json(200, {message: "Message received!"});      })};
