Ich versuche, den Node-http-Proxy als Reverse-Proxy zu verwenden, aber ich kann anscheinend keine POST- und PUT-Anforderungen zum Laufen bringen. Die Datei server1.js ist der Reverse-Proxy (zumindest für Anfragen mit der URL "/ forward-this") und server2.js ist der Server, der die Proxy-Anfragen empfängt. Bitte erläutern Sie, was ich falsch mache.

Hier ist der Code für server1.js:

// File: server1.js
//

var http = require('http');
var httpProxy = require('http-proxy');

httpProxy.createServer(function (req, res, proxy) {
    if (req.method == 'POST' || req.method == 'PUT') {
        req.body = '';

        req.addListener('data', function(chunk) {
            req.body += chunk;
        });

        req.addListener('end', function() {
            processRequest(req, res, proxy);
        });
    } else {
        processRequest(req, res, proxy);
    }

}).listen(8080);

function processRequest(req, res, proxy) {

    if (req.url == '/forward-this') {
        console.log(req.method + ": " + req.url + "=> I'm going to forward this.");

        proxy.proxyRequest(req, res, {
            host: 'localhost',
            port: 8855
        });
    } else {
        console.log(req.method + ": " + req.url + "=> I'm handling this.");

        res.writeHead(200, { "Content-Type": "text/plain" });
        res.write("Server #1 responding to " + req.method + ": " + req.url + "\n");
        res.end();
    }
}

Und hier ist der Code für server2.js:

// File: server2.js
// 

var http = require('http');

http.createServer(function (req, res, proxy) {
    if (req.method == 'POST' || req.method == 'PUT') {
        req.body = '';

        req.addListener('data', function(chunk) {
            req.body += chunk;
        });

        req.addListener('end', function() {
            processRequest(req, res);
        });
    } else {
        processRequest(req, res);
    }

}).listen(8855);

function processRequest(req, res) {
    console.log(req.method + ": " + req.url + "=> I'm handling this.");

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.write("Server #2 responding to " + req.method + ': url=' + req.url + '\n');
    res.end();
}
