Question

我运行了该程序来“嗅探”网络上的流量，但是遇到的第一个问题是它以十六进制等格式代码将其提供给我。所以我尝试转换代码，但是由于它是一个元组，所以它不起作用，所以我将元组转换为字符串。我收到此错误代码：

$ python sniffer.py
Traceback (most recent call last):
  File "sniffer.py", line 24, in <module>
    output1 = convertTuple(output)
  File "sniffer.py", line 8, in convertTuple
    output = functools.reduce(operator.add, (tup))
TypeError: can't concat tuple to bytes

这是我的完整代码：

import binascii
import struct
import socket
import functools
import operator

def convertTuple(tup):
    output = functools.reduce(operator.add, (tup))
    return output

s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_TCP)
s = socket.socket(socket.AF_INET,socket.SOCK_RAW,socket.IPPROTO_IP)
s.bind(("192.168.2.16",80))
s.setsockopt(socket.IPPROTO_IP,socket.IP_HDRINCL,1)
s.ioctl(socket.SIO_RCVALL,socket.RCVALL_ON)


while True:
    output = s.recvfrom(800)
    output1 = convertTuple(output)
    bytearray.fromhex(output1).decode()
    print(output1)

Answer 1

recvfrom返回一个元组(data,address)。如果您想用十六进制数据，请执行以下操作：

data,addr = s.recvfrom(800)
print(address,data.hex())

TypeError：无法将元组与字节连接
