使用 python 的 UTF-32 解码有问题

Question

我在端口 80 上有一个 UDP python 服务器，我希望有人访问服务器并使用 UTF-32 发送编码消息 "Start Server" 但是当我试着解码它，它给出

request_code = bytes.decode(x, 'utf-32')
TypeError: descriptor 'decode' requires a 'bytes' object but received a 'tuple'

代码如下：

Constants.Server0 = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
Constants.Server0.bind((local_ip, udp_port_main))
Constants.Main_server_data = Constants.Server0.recvfrom(2048)
for x in Constants.Main_server_data:
    request_code = bytes.decode(x, 'utf-32')
if request_code == 'Start Server':
    print("Authorized!")

我需要这方面的帮助，可以帮我解决。

Answer 1

recvfrom:

... The return value is a pair (string, address) where string is a string representing the data received and address is the address of the socket sending the data.

所以尝试：

request_code = bytes.decode(x[0], 'utf-32')

或更好的风格：

for string, address in Constants.Main_server_data:
    request_code = bytes.decode(string, 'utf-32')
