CUMUL模型复现与pcap文件读取问题

Question

在解码pcap文件并读取时，这部分出现了错误，如果不加utf-8会报gbk错误，加了以后
File "E:\PYTHON\lib\codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 0: invalid continuation byte
请求帮助我解决这个问题

def decodeTxt(filePath):
    times = []
    length = []
    packetNum = 0
    with open(filePath, "r",encoding="utf-8") as file:
        for dada in file:
            dada = dada.split(" ")
            times.append(float(dada[0]))
            length.append(int(dada[1]))
            packetNum += 1
    return times, length

Answer 1

这个错误说明文件中包含了无法用utf-8编码解码的字节。你可以尝试使用其他编码方式打开文件，比如gbk：

with open(filePath, "r", encoding="gbk") as file:

如果这个方式不行，说明文件的编码不是gbk或utf-8，你可以尝试使用其他编码方式打开文件，或者使用二进制方式打开文件并尝试解码。比如：

with open(filePath, "rb") as file:
    data = file.read()
    text = data.decode("xxx")  # 使用不同的编码方式进行解码
    lines = text.split("\n")
    for line in lines:
        # 处理每一行数据
