在swift 3中使用Json

import Foundation

let json: [String: Any] = [
    "name": "John Doe",
    "age": 30,
    "email": "johndoe@example.com"
]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: json, options: .prettyPrinted)
    // 处理jsonData
} catch {
    print("转换为JSON数据时出错：\(error)")
}

do {
    let jsonObject = try JSONSerialization.jsonObject(with: jsonData, options: [])
    // 处理jsonObject
    if let dictionary = jsonObject as? [String: Any] {
        // 处理字典对象
        let name = dictionary["name"] as? String
        let age = dictionary["age"] as? Int
        let email = dictionary["email"] as? String
        // 进一步处理数据
    }
} catch {
    print("转换为Swift对象时出错：\(error)")
}
