I just followed cnoon's suggest for the request cancel, the steps like:
- post the multipartFormData upload request;
- catch the upload progress and get the Alamofire.Request in the encodingCompletion;
- do cancel request;
Then the crash is coming.
All of the upload related code as below: private var request: Alamofire.Request?
func upload() {
Alamofire.upload(
.POST,
"\(AppManager_Inst.currentServerAddress)/cloud/uploadFile",
multipartFormData: { [unowned self] multipartFormData in
if self.uploadFile.data.isKindOfClass(UIImage),
let image = self.uploadFile.data as? UIImage,
let imageData = UIImagePNGRepresentation(image) {
multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "\(self.uploadFile.name).png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: { [unowned self] encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
self.request = upload
upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
dispatch_async(dispatch_get_main_queue()) {
let buffer = ["file": "\(self.uploadFile.id)", "speed": "\(bytesRead)", "readed": "\(totalBytesRead)", "all": "\(totalBytesExpectedToRead)"]
GlobalBroadcast_Inst.broadcastMsg(.uploading, msg: buffer)
}
}
upload.responseData(completionHandler: { (response) in
self.uploading = false
let resp = NewFileResp.parseFromData(response.data!)
})
case .Failure(let error):
self.uploading = false
print(error)
}
}
)
}
request?.cancel()
