“缩进错误：未缩进与任何外部缩进级别都不匹配”issu

Question

我试图做一个程序，嗅探DNS包，然后把包的qname放入字典的“key”，将包的dst ip放入字典的“value”，由于某种原因，我在第6行得到了这个错误

from scapy.all import * def query_ip_name(dns_packet): dns_dict = {} 6- strname = dns_packet[DNSQR].qname ip_add = dns_packet[IP].dst dns_dic.update(dns_name : dns_ip_name) def filter_dns(packet): return (DNS in packet and packet[DNS].opcode == 0 and packet[DNSQR].qtype == 1) def main(): print 'Starting to sniff!' packets = sniff(count=30, lfilter=filter_dns, prn = query_ip_name) print 'The sniffing was successfully ended.' print 'The dictionary is : ' main()

Answer 1

不要混淆制表符和空格。第dns_dict = {}行用制表符缩进，而文件的其余部分用空格表示。将制表符替换为4个空格。在

Answer 2

dns_dict的定义比strname缩进得更远，您需要将它们放在如下所示的相同缩进位置。我看到在代码片段的那一行中包含了行号。确保它不在您的代码中。在

def query_ip_name(dns_packet):

    dns_dict = {}

    strname = dns_packet[DNSQR].qname
