使用decodable在同一json - swift中解析来自两个不同容器的数据

{
  "container1": {
    "name": "John",
    "age": 30
  },
  "container2": {
    "city": "New York",
    "country": "USA"
  }
}

struct Container1: Decodable {
    let name: String
    let age: Int
}

struct Container2: Decodable {
    let city: String
    let country: String
}

struct DataModel: Decodable {
    let container1: Container1
    let container2: Container2
}

let jsonString = """
{
  "container1": {
    "name": "John",
    "age": 30
  },
  "container2": {
    "city": "New York",
    "country": "USA"
  }
}
"""

let jsonData = jsonString.data(using: .utf8)!

do {
    let dataModel = try JSONDecoder().decode(DataModel.self, from: jsonData)
    print(dataModel.container1.name) // 输出: John
    print(dataModel.container2.city) // 输出: New York
} catch {
    print("解析失败: \(error)")
}
