对于python和请求，如何进行正确的POST调用，以及在哪里可以找到头部？

import requests

url = "https://example.com/api"  # 替换为实际的API地址
data = {"key1": "value1", "key2": "value2"}  # 替换为实际的POST数据

response = requests.post(url, data=data)

if response.status_code == 200:
    print("请求成功")
    print(response.text)
else:
    print("请求失败")
    print(response.status_code)

import requests

url = "https://example.com/api"  # 替换为实际的API地址
data = {"key1": "value1", "key2": "value2"}  # 替换为实际的POST数据
headers = {"User-Agent": "Mozilla/5.0"}  # 添加自定义头部信息

response = requests.post(url, data=data, headers=headers)

if response.status_code == 200:
    print("请求成功")
    print(response.text)
else:
    print("请求失败")
    print(response.status_code)
