node.js - Redirected you too many times - Express/node on Heroku -


using express/node on heroku error: redirected many times or net::err_too_many_redirects in console.

i'm new express , tried add redirect http requests on 2 custom domains redirected https. what's breaking site. if has ideas fix amazing!

var express = require('express'); const path = require('path');  var app = express();  // process.env.port gets port heroku or goes 3000 const port = process.env.port || 3000;  app.enable('trust proxy');  // in production on heroku - re-route https if (process.env.node_env==="production") {   app.use((req, res, next) => {     if (req.header['x-forwarded-proto'] !== 'https') {       res.redirect('https://' + req.hostname + req.url);     } else {       next()     }   }) }  app.use(express.static(path.join(__dirname, '/public')));  app.get('*', (req, res) => {   res.sendfile(path.join(__dirname, 'public/index.html')); });  app.listen(port, function() {   console.log('express server on port:' + port); });

use req.header('x-forwarded-proto') instead.

and make sure, console.log process.env.node_env , req.header('x-forwarded-proto'), req.hostname, req.url see redirection works expected

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
