如何使用Swift和Rest API之间的连接来获取和发布JSON？

import Foundation

// 1. 创建API端点URL
let apiUrl = URL(string: "https://api.example.com/data")!

// 2. 创建URL会话对象
let session = URLSession.shared

// 3. 创建URL请求
var request = URLRequest(url: apiUrl)
request.httpMethod = "GET"

// 4. 发送请求并处理响应
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求错误：\(error.localizedDescription)")
        return
    }
    
    guard let httpResponse = response as? HTTPURLResponse else {
        print("无效的响应")
        return
    }
    
    if httpResponse.statusCode == 200 {
        // 5. 解析JSON数据
        if let data = data {
            do {
                if let json = try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {
                    // 6. 处理解析后的数据
                    // 在这里可以对解析后的JSON数据进行处理
                    print(json)
                }
            } catch {
                print("JSON解析错误：\(error.localizedDescription)")
            }
        }
    } else {
        print("请求失败，状态码：\(httpResponse.statusCode)")
    }
}

task.resume()
