在swift 3中使用urlsession在http报头中发送承载令牌的问题

import Foundation

// 创建一个URL对象
let url = URL(string: "https://example.com/api/endpoint")!

// 创建一个URLRequest对象
var request = URLRequest(url: url)

// 设置HTTP方法为GET
request.httpMethod = "GET"

// 设置Authorization头字段
let token = "your_token_here"
request.addValue("Bearer \(token)", forHTTPHeaderField: "Authorization")

// 创建一个URLSession对象
let session = URLSession.shared

// 发送HTTP请求
let task = session.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("请求失败：\(error)")
        return
    }
    
    // 处理服务器响应
    if let data = data {
        let responseString = String(data: data, encoding: .utf8)
        print("服务器响应：\(responseString ?? "")")
    }
}

// 启动任务
task.resume()
