在swift中检查具有不同响应的JSON值

let jsonString = """
{
    "name": "John",
    "age": 30,
    "city": "New York"
}
"""

// 将JSON字符串转换为Data
guard let jsonData = jsonString.data(using: .utf8) else {
    print("无法将JSON字符串转换为Data")
    return
}

do {
    // 将Data解析为JSON对象
    let jsonObject = try JSONSerialization.jsonObject(with: jsonData, options: [])

    // 检查JSON对象的类型
    switch jsonObject {
    case let jsonDictionary as [String: Any]:
        // JSON对象是一个字典
        if let name = jsonDictionary["name"] as? String {
            print("Name: \(name)")
        }
        if let age = jsonDictionary["age"] as? Int {
            print("Age: \(age)")
        }
        if let city = jsonDictionary["city"] as? String {
            print("City: \(city)")
        }
    case let jsonArray as [Any]:
        // JSON对象是一个数组
        for item in jsonArray {
            if let value = item as? String {
                print("Value: \(value)")
            }
        }
    default:
        print("无法识别的JSON对象")
    }
} catch {
    print("JSON解析错误: \(error)")
}
