如何仅更改请求url查询编码？

import urllib.parse

def change_query_encoding(url, new_encoding):
    # 解析URL
    parsed_url = urllib.parse.urlparse(url)
    query_params = urllib.parse.parse_qs(parsed_url.query, keep_blank_values=True)

    # 修改查询参数
    for param_name, param_values in query_params.items():
        for i in range(len(param_values)):
            # 修改参数值的编码
            param_values[i] = param_values[i].encode(new_encoding)

    # 重新构建URL
    new_query = urllib.parse.urlencode(query_params, doseq=True)
    new_url = urllib.parse.urlunparse(parsed_url._replace(query=new_query))

    return new_url

# 示例调用
original_url = "https://www.example.com/search?q=%E4%B8%AD%E6%96%87"
new_encoding = "utf-8"
modified_url = change_query_encoding(original_url, new_encoding)
print(modified_url)
