Creating an AWS lambda that acts as a proxy service

const https = require('https'); const destinationHostname = 'someurl.io' const destinationPath = '/somepath/dev/v1/hola' exports.handler = async (event) => { event.headers = event.headers || {} console.log("event", event) let postData = event.body let body let statusCode let headers await new Promise((resolve, reject) => { let options = { hostname: destinationHostname, port: 443, path: destinationPath, method: 'POST', headers: event.headers, rejectUnauthorized: false } // add additional headers if required, in my case I am setting/resetting Auth header options.headers['Authorization'] = 'Basic XXXX' // most do: options.header["X-Forwarded-Host"] = options.header.Host delete options.header.Host // also delete the host before forwarding the request var req = https.request(options, (res) => { statusCode = res.statusCode headers = res.headers console.log('statusCode:', res.statusCode); console.log('headers:', res.headers); let chunks = []; res.on("data", function (chunk) { chunks.push(chunk); }); res.on("end", function () { body = Buffer.concat(chunks).toString(); console.log("RES BODY: ", body) // body.toString()); resolve(); }); }) req.on('error', (e) => { console.error(e); }); req.write(postData) req.end() }) return { statusCode: statusCode || 200, headers: headers || {'content-type': 'application/json'}, body: body }; };
