为什么服务器未收到Ajax请求？

Question

I have to test a website with integration tests. The website sends all requests to a proxy:

var express = require("express"),
    http = require("http"),
    port = (process.env.PORT || 8001),
    server = module.exports = express(),
    httpProxy = require('http-proxy');

var proxy = httpProxy.createProxyServer();

// SERVER CONFIGURATION
// ====================
server.configure(function() {
    server.use(function(req, res, next) {
        console.log(req.url);
        if (req.url.indexOf('/any/thing') === 0) {
            console.log("url: " + req.url + ",\nheaders: " + req.headers + ",\nmethod: " + req.method);
            proxy.web(req, res, {target: 'http://127.0.0.1:1337'});
        } else {
            //console.log("url: " + req.url + ",\nheaders: " + req.headers + ",\nmethod: " + req.method);
            next();
        }
    });
    server.use('/anything', express["static"](__dirname + "/../public"));

    server.use(express.errorHandler({

        dumpExceptions: true,

        showStack: true

    }));

    server.use(express.bodyParser());

    server.use(server.router);

});

// SERVER
// ======

// Start Node.js Server
http.createServer(server).listen(port);

This proxy should communicate with this server:

var http = require('http');
http.createServer(function (req, res) {
    console.log("url: " + req.url + ",\nheaders: " + req.headers + ",\nmethod: " + req.method);
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end("{'user': 'garrarufa', 'loginToken': 'token'}");
}).listen(1337, "127.0.0.1");
console.log('Server running at http://127.0.0.1:1337/');

To login ajax is used:

$.ajax(this.apipath + "/login/", {
    type: "GET",
    async: false,
    success: function(...){...},
    error: function(...){...}
});

When I run the login request, immediately error is called. The request does not appear at the proxy server. At least the proxy does not print anything to the console. What is going on here? Shouldn't the ajax request be sent to the server?

Answer 1

Your proxy is running on

port = (process.env.PORT || 8001),

What port is your client code sending to? Ie what is this.apipath set to?

$.ajax(this.apipath + "/login/", {
    type: "GET",
    async: false,
    success: function(...){...},
    error: function(...){...}
});
