使用Python请求获取错误请求时出现错误400

import requests

url = "http://example.com/api/endpoint"
payload = {"key": "value"}

try:
    response = requests.get(url, params=payload)
    response.raise_for_status()  # 检查响应状态码，如果不是200则会抛出异常
except requests.exceptions.HTTPError as err:
    if response.status_code == 400:
        print("请求错误：", err)
    else:
        print("其他HTTP错误：", err)
except requests.exceptions.RequestException as err:
    print("请求异常：", err)
