从python套接字udp接收逗号分隔的字节

Question

我正在使用 python 3.7.4 尝试使用我使用 python 套接字通过 udp 接收的数据。 我需要数组中的数据。 我尝试过的一切要么出错，要么更改数据使其无用。

import socket
import select

sockets = []

for port in range(5201,5202):
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    server_socket.bind(('127.0.0.1', port))
    sockets.append(server_socket)

empty = []
while True:
    readable, writable, exceptional = select.select(sockets, empty, empty)
    for s in readable:
         (client_data, client_address) = s.recvfrom(1024)
         rport=(s.getsockname()[1])
         print (client_data)

for s in sockets:
   s.close()

输出是：

B '[255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255]'

我试图将这些数据放入一个数组中，以便我可以选择像 client_data[2] 这样的单个字节。

Answer 1

该格式基本上是 JSON：

>>> s = b'[255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255,255]'

>>> a = json.loads(s)
>>> a[0]

>>> len(a)
