python - 如何在python中更改url查询的值？

Question

 url = "http://www.example.com?type=a&type1=b&type2=c"
 urllist = get_urllist(url)
 trigger = ["'or '1'='1'"," 'OR '1'='2'","'OR a=a"]

def get_urllist(url): 
    url_parsed = urlparse.urlparse(url)
    #extract the query parameters of the URL 
    query =  urlparse.parse_qs(url_parsed.query)
    #get the list of query 
    query_list = query_list(query)
    #Get Base url 
    url = urlparse._replace(query=None).geturl()
    #modify url to get url_list 
    for query in query_list : 
       # change the original query to get the expected result 


 return url_list 


def query_list(query):
     for t in trigger:
         for key, value in query.items():
            query[key] += t
         query_list.append(query) 

     return query_list

如何通过更改查询参数值返回 URL 列表？

原始网址 =“ http://www.example.com?type=a&type1=b&type2=c”

预期结果:

url_list= [" http://www.example.com?type=a 'OR '1'='1'&type1=b'OR '1'='1'&type2=c'OR '1'='1'"," http://www.example.com?type=a 'OR '1 '='2'&type1=b'OR '1'='2'&type2=c'OR '1'='2'"," http://www.example.com?type=a 'OR a=a&type1=b'OR a=a&type2=c' '或 a=a"]

在 Python2.x

您可以使用 urlparse.urlparse 功能和ParseResult._replace方法:

import urlparse
url = "http://www.example.com?type=a&type1=b&type2=c"
trigger = ["'or '1'='1'"," 'OR '1'='2'","'OR a=a"]

parsed = urlparse.urlparse(url)
querys = parsed.query.split("&")
result = []
for pairs in trigger:
    new_query = "&".join([ "{}{}".format(query, pairs) for query in querys])
    parsed = parsed._replace(query=new_query)
    result.append(urlparse.urlunparse(parsed))

备注

urlparse 模块重命名为 urllib.parse在 Python 3 . 2to3 将源代码转换为 Python 3 时，该工具将自动调整导入。

在 Python3.x

您可以使用 urlparse.urlparse 功能也一样。

import urllib.parse as urlparse
url = "http://www.example.com?type=a&type1=b&type2=c"
trigger = ["'or '1'='1'"," 'OR '1'='2'","'OR a=a"]

parsed = urlparse.urlparse(url)
querys = parsed.query.split("&")
result = []
for pairs in trigger:
    new_query = "&".join([ "{}{}".format(query, pairs) for query in querys])
    parsed = parsed._replace(query=new_query)
    result.append(urlparse.urlunparse(parsed))

演示输出:

["http://www.example.com?type=a'or '1'='1'&type1=b'or '1'='1'&type2=c'or '1'='1'", "http://www.example.com?type=a 'OR '1'='2'&type1=b 'OR '1'='2'&type2=c 'OR '1'='2'", "http://www.example.com?type=a'OR a=a&type1=b'OR a=a&type2=c'OR a=a"]
