将字符串替换为基于queryurl中存在的键的精确匹配字词

import re
from urllib.parse import urlparse, parse_qs

def replace_string_with_queryurl_keys(string, queryurl):
    # 解析queryurl，获取键值对
    parsed_url = urlparse(queryurl)
    query_params = parse_qs(parsed_url.query)

    # 匹配待替换的字符串
    pattern = r'\b\w+\b'  # 示例正则表达式，匹配单词
    matches = re.findall(pattern, string)

    # 遍历匹配到的字符串，进行替换操作
    for match in matches:
        if match in query_params:
            value = query_params[match][0]
            string = string.replace(match, value)

    return string

# 示例用法
queryurl = 'https://www.example.com/?key1=value1&key2=value2'
string = 'Replace key1 and key2 with their corresponding values from queryurl.'

result = replace_string_with_queryurl_keys(string, queryurl)
print(result)
