Cancel a request Alamofire
Alamofire 4 / Swift 3 / Xcode 8
You can cancel a single request as below:
1 - First get the request:
let request = Alamofire.SessionManager.default.request(path!, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: createHeader()).responseJSON { response in
switch response.result {
case .success(let data):
success(data as AnyObject?)
case .failure(let error) :
failure(error as NSError)
}
}
2 - Then, in your viewDidDisappear, just call:
request.cancel()
You can cancel all requests as below:
Alamofire.SessionManager.default.session.getTasksWithCompletionHandler { (sessionDataTask, uploadData, downloadData) in
sessionDataTask.forEach { $0.cancel() }
uploadData.forEach { $0.cancel() }
downloadData.forEach { $0.cancel() }
}
did you try this solution:
let sessionManager = Alamofire.SessionManager.default
sessionManager.session.getTasksWithCompletionHandler { dataTasks, uploadTasks, downloadTasks in
dataTasks.forEach { $0.cancel() }
uploadTasks.forEach { $0.cancel() }
downloadTasks.forEach { $0.cancel() }
}
i also add a check to verify if is this the request that i want to cancel:
dataTasks.forEach
{
if ($0.originalRequest?.url?.absoluteString == url)
{
$0.cancel()
}
}
