我正在从tcp连接中读取数据。如果我从wireshark(网络监视器)读取数据,我得到02501c41d11ec06a471102,但如果我在python中读取数据,我会以字节为单位获取数据:
b'\x02P\x1cA\xd1\x1e\xc0jG\x11\x02'
<class 'bytes'>
我该如何转换? 我试过这个:
#!/usr/bin/env python
import socket
import binascii
import time
import sys
TCP_IP = '10.20.0.195'
TCP_PORT = 9761
BUFFER_SIZE = 2048
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
while 1:
data = s.recv(1024)
print (data)
data2 = data.decode("utf-8")
typ = type(data)
print (typ)
但如果在运行中我得到:
b'\x02P\x1cA\xd1\x00\x00\x02\xcb\x11\x00'
Traceback (most recent call last):
File "Z:/programeren/domotica/try again/receive.py", line 18, in <module>
data2 = data.decode("utf-8")
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd1 in position 4: invalid continuation byte
要明确我想转
b'\x02P\x1cA\xd1\x00\x00\x02\xcb\x11\x00'
到
02501c41d11ec06a471102
答案 0 :(得分:3)
使用binascii.b2a_hex(或binascii.hexlify)。
>>> import binascii
>>> binascii.b2a_hex(b'\x02P\x1cA\xd1\x00\x00\x02\xcb\x11\x00')
b'02501c41d1000002cb1100'
>>> binascii.b2a_hex(b'\x02P\x1cA\xd1\x00\x00\x02\xcb\x11\x00').decode('ascii')
'02501c41d1000002cb1100'
