Python使用quote()函数对接口请求值进行URL编码

urllib.parse.quote(string, safe='', encoding=None, errors=None)

import urllib.parse

# 待编码的字符串
string = "Hello World! This is a test. Spaces should be replaced."

# 使用quote函数进行编码
encoded_string = urllib.parse.quote(string)
print(encoded_string)  # 输出: Hello%20World%21%20This%20is%20a%20test.%20Spaces%20should%20be%20replaced.

        payload += f"&{key}={encoded_value}"
