これは未解決の質問の重複です

私のコードは非常に単純です:

for pcap_path in pcaps:
    f = open(pcap_path)
    pcap = dpkt.pcap.Reader(f)
    i = 1
    for ts, buf in pcap:
        eth = dpkt.ethernet.Ethernet(buf)
        ip = eth.data
        tcp = ip.data

        if tcp.dport == 80 and len(tcp.data) > 0:
            http = dpkt.http.Request(tcp.data)
            lst.append(http.headers['host'])
    f.close()

そして、ここにpcapがあります

dpkt が断然最速なので、他の pcap パーサーは使いたくありません。

たとえば、scapy よりも 50 倍高速です。

dpkt は、HTTPContent-Lengthヘッダーの値と実際のデータの長さが一致するかどうかを確認します。これは厳密に実施されます。すぐに修正されます。

当面は、dpkt ライブラリーのこのpass行にコメントを付けて、代わりにダミーのステートメントを追加することで、この作業を行うことができます。
