是否可以为 Alamofire 请求添加超时处理程序?

Is it possible to add timeout handler for Alamofire request?

在我的项目中，我以这种方式使用 Alamofire:

In my project I use Alamofire this way:

init() { let configuration = NSURLSessionConfiguration.defaultSessionConfiguration() configuration.timeoutIntervalForRequest = 30 self.alamofireManager = Alamofire.Manager(configuration: configuration) } func requestAuthorizationWithEmail(email:NSString, password:NSString, completion: (result: RequestResult) -> Void) { self.alamofireManager!.request(.POST, "myURL", parameters:["email": email, "password":password]) .responseJSON { response in switch response.result { case .Success(let JSON): //do json stuff case .Failure(let error): print(" Auth request failed with error: (error)") completion(result: .ConnectionFailed) } } }

请求失败提示

Error Domain=NSURLErrorDomain Code=-1001 请求超时."UserInfo={NSUnderlyingError=0x7fc10b937320 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=url, NSErrorFailingURLStringKey=url, NSErrorFailing_KeyStreamCode2CFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSLocalizedDescription=请求超时.}

Error Domain=NSURLErrorDomain Code=-1001 "The request timed out." UserInfo={NSUnderlyingError=0x7fc10b937320 {Error Domain=kCFErrorDomainCFNetwork Code=-1001 "(null)" UserInfo={_kCFStreamErrorCodeKey=-2102, _kCFStreamErrorDomainKey=4}}, NSErrorFailingURLStringKey=url, NSErrorFailingURLKey=url, _kCFStreamErrorDomainKey=4, _kCFStreamErrorCodeKey=-2102, NSLocalizedDescription=The request timed out.}

推荐答案

你可以比较 error._code 是否等于 -1001 即 NSURLErrorTimedOut 那么你知道这是一个超时.

You can compare error._code and if it is equal to -1001 which is NSURLErrorTimedOut then you know this was a timeout.

let manager = Alamofire.SessionManager.default manager.session.configuration.timeoutIntervalForRequest = 120 manager.request("yourUrl", method: .post, parameters: ["parameterKey": "value"]) .responseJSON { response in switch (response.result) { case .success: // succes path case .failure(let error): if error._code == NSURLErrorTimedOut { print("Request timeout!") } } }
