Question

为什么我遇到此错误，但我没有。我已经像使用Alamofire 5一样将Alamofire更改为AF。请指出问题所在和需要更改的地方。下面是我遇到错误的代码：

 private func callAlamoFireFormalData(makeThisFunction : @escaping (AFDataResponse<Any>)->Void )
{
    AF.request(url, method: httpMethod, parameters: paramters, encoding: encoding, headers: HTTPHeaders(self.headers ?? [:]))
        //.validate(statusCode: 200..<300)
        .responseJSON { response in
            
            //print("\(response.response?.statusCode)")
            guard response.response?.statusCode != 401
                else{
                    
                    Alamofire.SessionManager.default.session.getAllTasks { tasks in
                        tasks.forEach { $0.cancel() }
                    }
                    Helper.setApiToken(token: "")
                    Helper.removeUserInfo()
                    if var topController = UIApplication.shared.keyWindow?.rootViewController {
                        if let presentedViewController = topController.presentedViewController
                        {
                            topController = presentedViewController
                            topController.present(UIStoryboard.init(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "InitialNAV"), animated: true, completion: nil)
                        }
                        
                        // topController should now be your topmost view controller
                    }
                    //                        Alamofire.pause()
                    return
            }
            
            switch response.result
            {
            case let .failure(error):
                
                print(error)
                self.serverResponse.error = true
                self.serverResponse.message = String.serverError
                self.serverResponse.content = nil
                self.serverResponse.statusCode = response.response?.statusCode
                makeThisFunction()
                
            case .success(let value):
                
                let json = JSON(value)
                self.serverResponse.error = json["error"].boolValue
                self.serverResponse.message = json["message"].stringValue
                self.serverResponse.content = json["content"]
                self.serverResponse.statusCode = response.response?.statusCode
                makeThisFunction()
                
            }
    }
    
}

SessionManager类实际上在Alamofire 5中重命名为Session。因此，您可以使用以下代码替换实现：

Alamofire.Session.default.session.getAllTasks { tasks in
    tasks.forEach { $0.cancel() }
}

更新：正如@JonShier在评论中所述，取消所有请求的正确方法是调用Session的{{1}}函数：

cancelAllRequests(completingOnQueue:completion:)

模块“ Alamofire”没有名为“ SessionManager”的成员
