Http-proxy-middleware: Routing to HTTPS with invalid certificate

[fcoury]

Expected behavior

Routing HTTP to HTTPS with invalid certificate would work with process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

Actual behavior

It gives an error:

[HPM] Error occurred while trying to proxy request /service1/api/BasicOrder/OrderId/17072037 from localhost:8083 to http://localhost:8000 (UNABLE_TO_VERIFY_LEAF_SIGNATURE) (https://nodejs.org/api/errors.html#errors_common_system_errors)

Setup

• http-proxy-middleware: 0.17.14
• server: express 4.16.2

proxy middleware configuration

See below

server mounting

Complete code follows:

server.js

const fs = require('fs');
const express = require('express');

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';

const proxy = require('http-proxy-middleware');
const config = JSON.parse(fs.readFileSync('config.json', 'utf8'));

const { routes } = config;
const router = (req) => {
  const source = req.url;
  const target = routes.find(r => source.startsWith(r.from));
  return target && target.to;
};

const routingProxy = proxy({
  target: 'http://localhost:8000',
  router
});

const app = express();
app.use(routingProxy);
app.listen(8083);

config.json

{
  "routes": [
    { "from": "/service1", "to": "https://services-dev-01:10000" }
  ]
}

The solution was to add secure: false on the proxy configuration.
