Alamofire超时不适用于Swift 3

问题描述：

我正在使用Alamofire进行网络请求并希望添加超时。但Alamofire的功能不起作用。当我写了下面的代码Alamofire超时不适用于Swift 3

let manager = Alamofire.SessionManager.default 
    manager.session.configuration.timeoutIntervalForRequest = 1 // not working, 20 secs normally (1 just for try) 

    manager.request(url, method: method, parameters: params) 
     .responseJSON { response in 
      print(response) 
      ...

当我尝试没有Alamofire的网络请求，超时工作的成功没有任何反应。但还有其他错误。

var request = URLRequest(url: URL(string: url)!) 
request.httpMethod = "post" 
request.setValue("application/json", forHTTPHeaderField: "Content-Type") 
request.timeoutInterval = 1 // 20 secs normally (1 just for try) 
request.httpBody = try! JSONSerialization.data(withJSONObject: params!) 
...

那么，怎样才能在我斯威夫特3添加超时Alamofire？

我终于找到了解决这个答案：https://*.com/a/44948686/7825024

当我添加我的功能，但它的工作原理当我把它添加到AppDelegate中此配置代码不起作用！

AppDelegate.swift

import UIKit 

var AFManager = SessionManager() 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

     let configuration = URLSessionConfiguration.default 
     configuration.timeoutIntervalForRequest = 5 // seconds 
     configuration.timeoutIntervalForResource = 5 //seconds 
     AFManager = Alamofire.SessionManager(configuration: configuration) 

     return true 
    } 
    ... 
}

实施例：

AFManager.request("yourURL", method: .post, parameters: parameters).responseJSON { response in 
    ... 
}

不能修改URLSessionConfiguration的值之后，它已经被添加到URLSession，因此试图操纵Alamofire.SesssionManager.default.session.configuration总是会失败。要正确更改配置值，请按照Alamofire文档来实例化您自己的SessionManager。例如：

var defaultHeaders = Alamofire.SessionManager.defaultHTTPHeaders 
defaultHeaders["DNT"] = "1 (Do Not Track Enabled)" 

let configuration = URLSessionConfiguration.default 
configuration.httpAdditionalHeaders = defaultHeaders 

let sessionManager = Alamofire.SessionManager(configuration: configuration)
