在GO中解组嵌套的JSON对象

{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}

type Person struct {
  Name    string
  Age     int
  Address struct {
    Street string
    City   string
  }
}

jsonStr := `{"name":"John","age":30,"address":{"street":"123 Main St","city":"New York"}}`

var person Person
err := json.Unmarshal([]byte(jsonStr), &person)
if err != nil {
  fmt.Println("解组JSON对象失败:", err)
  return
}

fmt.Println(person.Name)              // 输出: John
fmt.Println(person.Age)               // 输出: 30
fmt.Println(person.Address.Street)    // 输出: 123 Main St
fmt.Println(person.Address.City)      // 输出: New York
