如何在python3中处理URL中的unicode字符串？

from urllib.parse import urlsplit, urlunsplit, quote, unquote

def process_unicode_url(url):
    # 解析URL
    scheme, netloc, path, query, fragment = urlsplit(url)

    # 对URL中的unicode字符串进行编码
    encoded_path = quote(path, safe='/:')
    encoded_query = quote(query, safe='=&')

    # 重新组合URL
    url_with_encoded_unicode = urlunsplit((scheme, netloc, encoded_path, encoded_query, fragment))

    return url_with_encoded_unicode

# 测试
url = "https://www.example.com/你好?key=值"
processed_url = process_unicode_url(url)
print(processed_url)

import requests

response = requests.get(processed_url)
print(response.text)
