python scapy读取pcap包

废话不说,直接上代码.相对来说还是比较简单的

import scapy_http.http
try:
    import scapy.all as scapy
except ImportError:
    import scapy


def parse_http_pcap(pcap_path):
    pcap_infos = list()
    packets = scapy.rdpcap(pcap_path)
    for p in packets:
        print "----"
        # 判断是否包含某一层，用haslayer
        if p.haslayer("IP"):
            src_ip = p["IP"].src
            dst_ip = p["IP"].dst
            print "sip: %s" % src_ip
            print "dip: %s" % dst_ip
        if p.haslayer("TCP"):
            # 获取某一层的原始负载用.payload.original
            raw_http = p["TCP"].payload.original
            sport = p["TCP"].sport
            dport = p["TCP"].dport
            print "sport: %s" % sport
            print "dport: %s" % dport
            print "raw_http:\n%s" % raw_http
        if p.haslayer("HTTPRequest"):
            host = p["HTTPRequest"].Host
            uri = p["HTTPRequest"].Path
            # 直接获取提取好的字典形式的http数据用fields
            http_fields = p["HTTPRequest"].fields
            http_payload = p["HTTPRequest"].payload.fields
            print "host: %s" % host
            print "uri: %s" % uri
            print "http_fields:\n%s" % http_fields
            print "http_payload:\n%s" % http_payload
