如何使用SWIFT使用JSON将数据从多个视图控制器发布到服务器

let userData: [String: Any] = [
    "name": "John Doe",
    "age": 25
]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: userData, options: [])
    // jsonData现在包含了转换后的JSON数据
} catch {
    print("JSON转换失败: \(error)")
}

let url = URL(string: "https://example.com/api/user")!

var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData

let session = URLSession.shared
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求失败: \(error)")
        return
    }
    
    // 处理服务器的响应
}
task.resume()
