angularjs - Why does angular-socket-io complain with 'Error during WebSocket handshake: Unexpected response code: 400?' -


i have node application (angular-fullstack) moved http https. working, socket connection isn't. missing?

in socketfactory have:

var iosocket = io('https://localhost', {   path: '/socket.io-client' });

which believe causes transport use 'wss://'. https connection good. time, believed somehow nginx not handling proxy correctly. incorrect.

next, changed form 'https://locahost' 'https://xxx_actual_server_url_xxxx' , works after initial page reload. see one:

websocket connection 'wss://xxx_actual_server_url_xxxx/ socket.io-client/?eio=3&transport=websocket&sid=y4_ckvyterz_f1zcaaak'  failed: error during websocket handshake: unexpected response code: 400

what causing this? , how around it? not doing load balancing or , running development server 'grunt serve'. thoughts?

thanks!

after searching , hunting, discovered when using sockets nginx needed add following proxy stuff:

proxy_set_header upgrade $http_upgrade; proxy_set_header connection "upgrade"; proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;

having done that, good. else. full set of parameters forwarding proxy nginx is:

 location / {     proxy_set_header   x-real-ip $remote_addr;     proxy_set_header   host      $host;     proxy_pass https://127.0.0.1:9000;     proxy_http_version 1.1;     proxy_set_header upgrade $http_upgrade;     proxy_set_header connection "upgrade";     proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;   }

thanks looked @ this!

utf 8 - split utf-8 string into bytes in python -

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
