使用正则表达式重写url

original_url = "https://example.com/path?param1=value1&param2=value2&param3=value3"

import re

# 原始URL
original_url = "https://example.com/path?param1=value1&param2=value2&param3=value3"

# 正则表达式模式
pattern = r'(param2)=([^&]+)'

# 替换函数
def replace_param(match):
    if match.group(1) == 'param2':
        return f'param2=new_value2'
    return match.group(0)

# 使用re.sub进行替换
rewritten_url = re.sub(pattern, replace_param, original_url)

print("Original URL:", original_url)
print("Rewritten URL:", rewritten_url)

Original URL: https://example.com/path?param1=value1&param2=value2&param3=value3
Rewritten URL: https://example.com/path?param1=value1&param2=new_value2&param3=value3
