Socket.io. How to detect incoming data -


for socket.io, how listen incoming data other emitted "event" types? looking read , detect proxyprotocol string.

i did little research. looks proxy string sent initial http request on separate line command this:

proxy tcp4 192.168.0.1 192.168.0.11 56324 80\r\n / http/1.1\r\n host: 192.168.0.11\r\n \r\n

you can see explained in this article.

so, need handled http server fields initial http request starts websocket. occurs in initial connection stage before websocket established. so, not listen afterwards. take study of socket.io code figure out if stores information on socket.io socket or how hook initial http handler see info. little more research.

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
