[英]Alamofire! In multipart file upload progress.isPausable returns false, and progress.pause() does not work
我想上传具有暂停和恢复功能的文件,只有上传能正常工作!
代码如下!
configuration = URLSessionConfiguration.background(withIdentifier:
"com.example.app.background")
sessionManager = Alamofire.SessionManager(configuration: configuration)
sessionManager.upload( // Or Alamofire.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(self.videoURL, withName: "file", fileName:
fileName, mimeType: "video/(extention)")
},
to: myServer,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
if response.error == nil {
self.bar_progress.progress = 1
self.lbl_uploadProgress.text = "Upload Progress: 100%"
print("Upload Status Success: ", response)
}
else{
print("Upload Status Fail: ", response)
}
}
upload.uploadProgress { progress in
print("Progress: ", progress.fractionCompleted)
self.bar_progress.progress = Float(progress.fractionCompleted)
self.lbl_uploadProgress.text = "Upload Progress: \( Int(progress.fractionCompleted * 100))%"
if progress.isPausable{
print("Pausable") // THIS IS WHAT I WANT
}
else{
print("Not pausable") // THIS IS MY PROBLEM
}
}
case .failure(let encodingError):
print(encodingError)
self.bar_progress.progress = 0
self.lbl_uploadProgress.text = "Upload Progress: 0%"
}
}
)
提前致谢。
您需要计算上传文件的进度。 如果进度小于100%,则您可以保持视图暂停,一旦视图100%,您可以像这样恢复它。
Alamofire.upload(
.POST,
URLString: "http://httpbin.org/post",
multipartFormData: { multipartFormData in
multipartFormData.appendBodyPart(fileURL: unicornImageURL, name: "unicorn")
multipartFormData.appendBodyPart(fileURL: rainbowImageURL, name: "rainbow")
},
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
let progress: Float = Float(totalBytesRead)/Float(totalBytesExpectedToRead) // you can give this progress to progressbar progress
let value = Int(progress * 100) // this is the percentage of the video uploading
if value == 100
{ // resume the view}
else
{ // keep it pause}
}
upload.responseJSON { request, response, result in
debugPrint(result)
}
case .Failure(let encodingError):
print(encodingError)
}
}
)
