Swift 使用 Alamofire 处理超时

是否可以为Alamofire请求添加超时处理程序？

在我的项目中，我使用Alamofire的方式如下:

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("\n\nAuth request failed with error:\n \(error)")
                completion(result: .ConnectionFailed)
            }
    }
}
