Ich mache eine einfache Python-Anwendung, die Menschen über eine CLI miteinander kommunizieren können. Ich bin relativ neu auf dem Sockets-Modul, aber mein Code hat keine Probleme. Außer einem. Wenn ich meine zwei Skripts (chatclient.py und chatserver.py) ausführe, laufen sie gut. Der Server wird gestartet, und der Client fragt den Benutzer nach seinem Namen und der Nachricht. Doch nach dem Klicken Sie hier die Nachricht zu senden, i erhalten:Python3 Socket-Modul: Entschlüsselung str
TypeError: decoding str not supported
Ich habe .encode ('utf-8)/.decode (' utf-8'), aber immer noch die gleichen Fehler versucht, mit. Der Code wird unten sein (mit mehreren Kommentaren um den "falschen" Code).

tLock = threading.Lock() #creates a lock for the thread and prevents output to the screen
shutdown = False
def receiving(name, sock):
while not shutdown: #while the program is still running
try:
tLock.acquire() #acquires the lock
while True:
data, addr = sock.recv(1024).decode('utf-8') #gets the data and address from the data received
print(str(data))
except:

finally:
tLock.release() #releases the lock
host = "127.0.0.1" #uses localhost as the host
port = 0 #picks up any free port on the computer
server = ("127.0.0.1",5000)

Es gibt keine 'decode' Methode für Strings in Python 3 als Strings Strings jetzt Unicode sind. Sie können das Byte-Objekt decodieren (z. B. das Ergebnis von 'bytes (blah)' oder 'blah" .encode() '). – avysk
