从URL中搜索并删除包含可选字符的参数

import urllib.parse

def remove_optional_params(url):
    # 解析URL
    parsed_url = urllib.parse.urlparse(url)
    # 获取查询参数部分
    query_params = urllib.parse.parse_qs(parsed_url.query)

    # 遍历查询参数
    for param, values in query_params.items():
        # 判断参数值中是否包含可选字符，这里以空格为例
        values = [value.replace(" ", "") for value in values]
        # 更新参数值
        query_params[param] = values

    # 构建新的查询参数字符串
    new_query_string = urllib.parse.urlencode(query_params, doseq=True)

    # 构建新的URL
    new_url = urllib.parse.urlunparse((
        parsed_url.scheme,
        parsed_url.netloc,
        parsed_url.path,
        parsed_url.params,
        new_query_string,
        parsed_url.fragment
