javascript - How to force https redirect on heroku with express 4.0? -


i don't understand why following code not accomplish this? can explain going wrong? http requests should redirected https on heroku, not on localhost. if point me example of working appreciate it. feel should simple , straightforward.

var app = express();  var https_redirect = function () {   return function(req, res, next) {     if(process.env.node_env === 'production'){       if(req.headers['x-forwarded-proto'] != 'https') {         return res.redirect('https://' + req.headers.host + req.url);       } else {         return next();       }     } else {       return next();     }   }; }; app.use(https_redirect());  var server = app.listen(config.port, config.ip, function () { });  exports = module.exports = app;

i did searching , looks have should work.

your middleware's req, res, next params being lost having been wrapped outer function.

try this:

var https_redirect = function(req, res, next) {     if (process.env.node_env === 'production') {         if (req.headers['x-forwarded-proto'] != 'https') {             return res.redirect('https://' + req.headers.host + req.url);         } else {             return next();         }     } else {         return next();     } };  app.use(https_redirect);

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
