如何在下面的代码中发送包含body的POST请求

import requests
import json

# 创建包含请求体数据的字典或JSON对象
data = {
    "name": "John",
    "age": 30
}

# 将字典或JSON对象转换为JSON字符串
json_data = json.dumps(data)

# 发送POST请求
url = "https://example.com/api"
headers = {"Content-Type": "application/json"}  # 设置请求头，指定Content-Type为JSON
response = requests.post(url, data=json_data, headers=headers)

# 处理服务器的响应
if response.status_code == 200:
    # 请求成功
    response_data = response.json()  # 解析响应体数据
    print(response_data)
else:
    # 请求失败
    print("Request failed with status code:", response.status_code)
