如何从字符串中获取带有表单参数的url？

import re

def get_form_params_from_url(url_string):
    # 提取URL部分
    url_match = re.search('(https?://[^\s]+)', url_string)
    if url_match:
        url = url_match.group(1)
    else:
        return None

    # 提取参数部分
    params_match = re.search('\?(.*)', url_string)
    if params_match:
        params = params_match.group(1)
    else:
        return None

    # 提取键值对
    param_pairs = params.split('&')
    form_params = {}
    for pair in param_pairs:
        key_value = pair.split('=')
        if len(key_value) == 2:
            key = key_value[0]
            value = key_value[1]
            form_params[key] = value

    return form_params

# 示例用法
url_string = "https://www.example.com/path?param1=value1&param2=value2"
form_params = get_form_params_from_url(url_string)
print(form_params)

{'param1': 'value1', 'param2': 'value2'}
