POST request timeout and BadRequestError: request aborted

[bitk0der]

Hello, thank you for that module.

I'm using cors-anywhere as ExpressJS middleware for GET and POST requests. GET requests working as expected, but POST request can not be parsed by target test server and body parser always gives: BadRequestError: request aborted.

Comments in example code.

Cors anywhere middleware:

var app = require('express')();
var corsAnywhere = require('cors-anywhere');

var port = 3330;

let proxy_cors = corsAnywhere.createServer({
  originWhitelist: [], // for test purpose
  requireHeaders: [], // for test purpose
  removeHeaders: [], // for test purpose
  httpProxyOptions: {
    secure: false
  },
});

app.get('/proxy/:proxyUrl*', async (req, res) => {
  req.url = req.url.replace('/proxy/', '/');
  proxy_cors.emit('request', req, res);
}); // WORKING

app.post('/proxy/:proxyUrl*', async (req, res) => {
  req.url = req.url.replace('/proxy/', '/');
  proxy_cors.emit('request', req, res);
}); // NOT WORKING, BECAUSE SOMETHING SENT WRONG

app.listen(port, function () {
    console.log('Server started on port:', port);
});

Test ExpressJS server:

var app = require('express')();
var bodyParser = require('body-parser');

var port = 3333;

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));

app.get('/test', function (req, res) {
    // WORKING FINE
    res.json({status: 'ok'});
});

app.post('/test', function (req, res) {
    // DIRECT CALL (without cors-anywhere) - WORKS
    // CORS-ANYWHERE: REQUEST NEVER GET HERE AND AFTER TIMEOUT, BODYPARSER GOT: BadRequestError: request aborted
    res.json({status: 'ok'});
});

app.listen(port, function () {
    console.log('Server started on port:', port);
});

Works for me with Node v14.13.1, cors-anywhere 0.4.3, express 4.17.1, and curl http://127.0.0.1:3330/proxy/http://127.0.0.1:3333/test -dparam=value

How can this issue be reproduced?

Hi, i encounter the same issue.

i tried to do a POST request with a JSON body, i returned timeout.
i've no problem when doing a GET request or a POST request without body.

here's my example of POST request:
POST http://localhost:3100/proxy/https://postman-echo.com/post
JSON body: { "test": "anything" }
