Swift 5:简单字符串URLRequest

import Foundation

// 创建 URL 对象
if let url = URL(string: "https://api.example.com/data") {
    // 创建 URLRequest 对象
    var request = URLRequest(url: url)
    request.httpMethod = "GET"
    
    // 创建 URLSession 对象
    let session = URLSession.shared
    
    // 创建数据任务
    let task = session.dataTask(with: request) { data, response, error in
        if let error = error {
            print("Error: \(error.localizedDescription)")
            return
        }
        
        if let data = data {
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [])
                print("JSON: \(json)")
            } catch {
                print("JSON parsing error: \(error.localizedDescription)")
            }
        }
    }
    
    // 启动任务
    task.resume()
}

request.timeoutInterval = 30 // 设置超时时间为30秒

if let httpResponse = response as? HTTPURLResponse {
    print("Status code: \(httpResponse.statusCode)")
