如何映射JSON对象中的字段数据

{
  "name": "John Doe",
  "age": 30,
  "email": "johndoe@example.com",
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  }
}

import json

# 假设json_data是接收到的JSON数据
json_data = '{"name": "John Doe", "age": 30, "email": "johndoe@example.com", "address": {"street": "123 Main St", "city": "New York", "country": "USA"}}'

# 解析JSON数据
data = json.loads(json_data)

# 访问和提取字段值
name = data["name"]
age = data["age"]
email = data["email"]
street = data["address"]["street"]
city = data["address"]["city"]
country = data["address"]["country"]

# 打印字段值
print("Name:", name)
print("Age:", age)
print("Email:", email)
print("Street:", street)
print("City:", city)
print("Country:", country)

Name: John Doe
Age: 30
Email: johndoe@example.com
Street: 123 Main St
City: New York
Country: USA
