robertklep 提供了一个很好的答案,完全为我解决了这个问题。我将它改编成一个完整的解决方案,以防其他人想做类似的事情:
节点(服务器端):
// Extend Express' Router to a simple name
app.sio = new express.Router();
app.sio.socketio = require('socket.io').listen(server, { log: false });
// Map all sockets requests to HTTP verbs, which parse
// the request and pass it into a simple callback.
app.sio.socketio.sockets.on('connection', function (socket) {
var verbs = ['GET', 'POST', 'PUT', 'PATCH', 'DELETE'];
for (var i = 0; i < verbs.length; ++i) {
var go = function(verb) {
socket.on(verb, function (url, data) {
var route = app.sio.match(verb, url);
if (route && route.callbacks.length) {
var req = {url: url, params: route.params, data: data, socket:socket}
route.callbacks[0](req);
}
});
}(verbs[i]);
}
});
// Simplify Socket.IO's 'emit' function and liken
// it traditional Express routing.
app.sio.end = function(req, res) {
req.socket.emit('response', req.url, res);
}
// Here's an example of a simplified request now, which
// looks nearly just like a traditional Express request.
app.sio.get('/foo/:bar', function(req) {
app.sio.end(req, 'You said schnazzy was ' + req.data.schnazzy);
});
客户端:
// Instantiate Socket.IO
var socket = io.connect('http://xxxxxx');
socket.callbacks = {};
// Similar to the server side, map functions
// for each 'HTTP verb' request and handle the details.
var verbs = ['get', 'post', 'put', 'path', 'delete'];
for (var i = 0; i < verbs.length; ++i) {
var go = function(verb) {
socket[verb] = function(url, data, cb) {
socket.emit(String(verb).toUpperCase(), url, data);
if (cb !== undefined) {
socket.callbacks[url] = cb;
}
}
}(verbs[i]);
}
// All server responses funnel to this function,
// which properly routes the data to the correct
// callback function declared in the original request.
socket.on('response', function (url, data) {
if (socket.callbacks[url] != undefined) {
socket.callbacks[url](data);
}
});
// Implementation example, params are:
// 1. 'REST' URL,
// 2. Data passed along,
// 3. Callback function that will trigger
// every time this particular request URL
// gets a response.
socket.get('/foo/bar', { schnazzy: true }, function(data){
console.log(data); // -> 'You said schnazzy was true'
});
谢谢你的帮助,罗伯特克莱普!
