如何在swift中创建模型并将Json响应添加到模型中？

class Person {
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
}

class Person: Codable {
    var name: String
    var age: Int
    
    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }
}

let jsonString = """
{
    "name": "John",
    "age": 25
}
"""

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

do {
    let decoder = JSONDecoder()
    let person = try decoder.decode(Person.self, from: jsonData!)
    print(person.name) // 输出：John
    print(person.age) // 输出：25
} catch {
    print("解码失败：\(error)")
}

let person = Person(name: "John", age: 25)

do {
    let encoder = JSONEncoder()
    let jsonData = try encoder.encode(person)
    let jsonString = String(data: jsonData, encoding: .utf8)
    print(jsonString!) // 输出：{"name":"John","age":25}
} catch {
    print("编码失败：\(error)")
}
