我在尝试打开.pcap文件时遇到问题.在scapy.utils中有RawPcapReader

    try:
        self.f = gzip.open(filename,"rb")
        magic = self.f.read(4)
    except IOError:
        self.f = open(filename,"rb")
        magic = self.f.read(4)
    if magic == "\xa1\xb2\xc3\xd4": #big endian
        self.endian = ">"
    elif  magic == "\xd4\xc3\xb2\xa1": #little endian
        self.endian = "<"
    else:
        raise Scapy_Exception("Not a pcap capture file (bad magic)")
    hdr = self.f.read(20)
    if len(hdr)<20:
        raise Scapy_Exception("Invalid pcap file (too short)")

我的魔法有价值"\n\r \n \n \n"但RawPcapReader期待魔法=="\ xa1\xb2\xc3\xd4"或魔术=="\ xd4\xc3\xb2\xa1".

你能告诉我可能是什么问题吗？用.pcap文件？我正在使用python版本2.7
