Working on a Swift project, and apparently the file I'm uploading isn't an image. I'm also using the Alamofire utility.
let uuid = NSUUID().UUIDString
print ("MARK -- UUID is " + uuid)
let image = imageView.image
Alamofire.upload(.POST, "{RETRACTED}", multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(image!, 0.6) {
multipartFormData.appendBodyPart(data: imageData, name: uuid, fileName: uuid + ".png", mimeType: "image/png")
}
}, encodingCompletion: {
encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.responseJSON { response in
print(response.request) // original URL request
print(response.response) // URL response
print(response.data) // server data
print(response.result) // result of response serialization
if let JSON = response.result.value {
print ("JSON \(JSON)")
self.displayAlert("Uploaded!", message: "{RETRACTED}", responseButtonText: "{RETRACTED}")
}
}
case .Failure(let encodingError):
print(encodingError)
}
})
Here's the JSON response (I also have the PHP server side code if needed):
JSON {
response = "That file wasn't an image (Only .png and .jpg/.jpeg images are accepted). The type is ";
responseCode = 0;
}
Thanks guys.
You are sending an jpg image, but specifying mime type for png. Change mime type to "image/jpeg" or send a png file.

Code Revised based on suggestion solution but still not working. Videos are uploading as 0 bytes. I have an app where a user should be able to record a video from their phone and when 'Use Video' is selected it uploads the video to our PHP Server. The file is uploading successfully and based on the size shown it is not empty. However when I go to play the video in the app or even directly through the browser it won't play. There's no issue with the playback code as I've hardcoded links to other videos on other sites and it works fine. Code is below, any help is much appreciated.
// Finished recording a video

Okay, I did code something to actually encode and upload a video.
Unfortunately, doing a multipart/form-data in URLSession is actually pretty hard, so I used Alamofire to actually upload the video.
This is the code in parts:
UIImagePickerControllerDelegate (this is the one you should modify, check the //TODO comments)
// MARK: UIImagePickerControllerDelegate
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
print("Cancelled video operation.")
dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
guard let mediaType = info[UIImagePickerControllerMediaType] as? String else {
print("Error with media type. Cancelling.")
dismiss(animated: true, completion: nil)
return;
}
print("Media type: \(mediaType)")
if ( mediaType == "public.movie" ) { // Video selected
let videoURL: URL
if info[UIImagePickerControllerMediaURL] != nil {
videoURL = info[UIImagePickerControllerMediaURL] as! URL
}
else {
videoURL = info[UIImagePickerControllerReferenceURL] as! URL
}
if ( picker.sourceType == .camera ) {
// The original video came from the camera, so it's considered new
// Save it to the photo library
saveVideo(url: videoURL, albumName: "MyApp")
}
// Dismiss the media picker and then re-encode the video
dismiss(animated: true) {
self.exportVideoToMP4(url: videoURL) { (exportedVideoURL) in
guard let tempURL = exportedVideoURL else {
print("ERROR: Unknown error. The exported video URL is nil.")
return
}
print("Temporary video successfully exported to: \(tempURL.absoluteString)")
// TODO: Add your own POST parameters
let uuid = UUID().uuidString
let params = [
"uuid" : uuid,
"user" : "myUserNameOrWhatever"
]
// TODO: Change the parameters for uploading
self.upload( to: "http://yourweb.com/uploadVideo.php", // The URL to send the upload to
videoURL: tempURL, // The file URL of the temporary video file
parameters: params, // The POST parameters you want to send along with the upload
fileName: "vid-\(uuid).mp4", // The filename you want the server to receive.
fieldName: "video_file" // This is "name" from <input type="file" name="video_file" ... /> in HTML
) { (response) in
guard let resp = response else {
print("ERROR: Empty or unrecognizable response from server.")
return
}
print("Video uploaded. RESPONSE: \(resp)")
//: TODO Parse the server response after uploading
}
}
}
}
}
Photo Library helper methods
// MARK: Photo Library
func saveVideo(url: URL, albumName: String) {
// Check authorization status before trying to save the video
switch PHPhotoLibrary.authorizationStatus() {
case .notDetermined:
PHPhotoLibrary.requestAuthorization() { (status) in
switch status {
case .authorized:
self.saveVideo(url: url, albumName: albumName) // Re-try to save the video after authorization
return
default:
return
}
}
case .authorized:
// Save the video to the Photo Library here
if let assetCollection = assetCollection(albumName: albumName) {
// Asset collection exists, insert directly
insertVideo(url: url, assetCollection: assetCollection)
}
else {
// Asset collection doesn't exist, create it and then insert
PHPhotoLibrary.shared().performChanges({
PHAssetCollectionChangeRequest.creationRequestForAssetCollection(withTitle: albumName)
}, completionHandler: { (success, error) in
guard success else {
print("ERROR: \(error!.localizedDescription)")
return
}
let createdAssetCollection = self.assetCollection(albumName: albumName)!
self.insertVideo(url: url, assetCollection: createdAssetCollection)
})
}
return
default:
// Not authorized
print("Not authorized to save a video to the Photo Library.")
return
}
}
func assetCollection(albumName: String) -> PHAssetCollection? {
let fetchOptions = PHFetchOptions()
fetchOptions.predicate = NSPredicate(format:"title == '\(albumName)'")
let fetchResult = PHAssetCollection.fetchAssetCollections(with: .album, subtype: .albumRegular, options: fetchOptions)
return fetchResult.firstObject
}
func insertVideo(url: URL?, assetCollection: PHAssetCollection) {
guard let videoURL = url else {
print("ERROR: The URL to insert into the Photo Library is empty.")
return
}
PHPhotoLibrary.shared().performChanges({
let createAssetRequest = PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: videoURL)
let assetPlaceholder = createAssetRequest?.placeholderForCreatedAsset
let changeRequest = PHAssetCollectionChangeRequest(for: assetCollection)
let enumeration: NSArray = [assetPlaceholder!]
changeRequest?.addAssets(enumeration)
}, completionHandler: { (success, error) in
guard success else {
print("ERROR: \(error!.localizedDescription)")
return
}
print("Video saved successfully to the Photo Library album.")
})
}
Video Uploading (using Alamofire, installed from CocoaPods)
// MARK: Video upload
func upload(to uploadAddress: String, videoURL: URL, parameters: [String:Any]?, fileName: String, fieldName: String, _ completion: ((String?) -> Void)?) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
// Add the video file (if data is correct)
if let videoData = FileManager.default.contents(atPath: videoURL.path) {
multipartFormData.append(videoData, withName: fileName)
}
// Add the post params (if available)
if let params = parameters {
for (key, value) in params {
multipartFormData.append( (value as! String).data(using: .utf8)! , withName: key)
}
}
}, to: uploadAddress)
{ (result) in
switch result {
case .success(let upload, _, _):
upload.responseString { (response) in
if let completionHandler = completion {
completionHandler(response.result.value)
}
}
case .failure(let encodingError):
print("ERROR: \(encodingError.localizedDescription)")
if let completionHandler = completion {
completionHandler(nil)
}
}
}
}
AVFoundation (the encoding method)
// MARK: AVFoundation
func exportVideoToMP4(url: URL, _ completion: #escaping ((URL?) -> Void)) {
// Show some sort of indicator here, as this could take a while
// Generate a temporary URL path to export the video
let relativePath = "myAppTempVideoExport.mp4";
let outputFilePath = NSTemporaryDirectory() + relativePath;
print("Temp file path: \(outputFilePath)")
// If there's any temp file from before at that path, delete it
if FileManager.default.fileExists(atPath: outputFilePath) {
do {
try FileManager.default.removeItem(atPath: outputFilePath)
}
catch {
print("ERROR: Can't remove temporary file from before. Cancelling export.")
completion(nil)
return
}
}
// Export session setup
let outputFileURL = URL(fileURLWithPath: outputFilePath)
let asset = AVAsset(url: url) // Original (source) video
// The original video codec is probably HEVC, so we'll force the system to re-encode it at the highest quality in MP4
// You probably want to use medium quality if this video is intended to be uploaded (as this example is doing)
if let exportSession = AVAssetExportSession(asset: asset, presetName: AVAssetExportPresetHighestQuality) {
exportSession.outputURL = outputFileURL
exportSession.outputFileType = .mp4
exportSession.exportAsynchronously {
// Hide the indicator for the export session
switch exportSession.status {
case .completed:
print("Video export completed.")
completion(outputFileURL)
return
case .failed:
print("ERROR: Video export failed. \(exportSession.error!.localizedDescription)")
completion(nil)
return
case .cancelled:
print("Video export cancelled.")
completion(nil)
return
default:
break
}
}
}
else {
print("ERROR: Cannot create an AVAssetExportSession.")
return
}
}
Now, for this to work, you obviously have to record a video, import frameworks and specify that your view controller conforms to protocols, so:
import AVFoundation
import Photos
import Alamofire
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
let imagePicker = UIImagePickerController()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
imagePicker.sourceType = .camera
imagePicker.delegate = self
imagePicker.showsCameraControls = true
imagePicker.allowsEditing = true
imagePicker.mediaTypes = ["public.movie"]
DispatchQueue.main.async {
self.present(self.imagePicker, animated: true, completion: nil)
}
}
}
I hope this is useful to you, feel free to ask.
I am trying to upload file to server. I am using SlimFramework and PHP in my backend code and it is in RESTful form. Image uploading works very well if I upload it through Postman however I am not able to get it to work using Swift and Alamofire library.
In the route I have in backend, I get the file like this, from body parameter:
$image = $request->getUploadedFiles();
and to upload I use the:
$image->moveTo("myPath");
In Swift I have router, which gives .post method and the route URL and I tried like this:
func uploadImage(user_id: Int, image: Data, completion: #escaping (_ error: Error?, _ success: Bool)->Void) {
let parameters = [
"user_id": user_id,
"newFile": image
] as [String : Any]
Alamofire.request(Router.imageUplaod(parameters: parameters))
.validate(statusCode: 200..<300)
.responseJSON { response in
switch response.result{
case .failure(let error):
completion(error, false)
print(error)
case .success(let value):
//Registered sucesfully! let json = JSON(value)
completion(nil, true)
}//Switch case
}//Alamofire
}
And I call it like this:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let chosenProfileImage = info[UIImagePickerControllerEditedImage] as! UIImage
let imageData = UIImageJPEGRepresentation(chosenProfileImage, 0.2)
profileImageView.image = chosenProfileImage
dismiss(animated: true) {
API.uploadImage(user_id: User.sharedInstance.user_id, image: imageData!) { (error, success) in
if success{
print("IMAGE UPLOADDED")
}
}
}
}
This is my backend route:
$this->post('/image/upload', function($request, $response, $args){
global $database;
$data = $request->getParsedBody();
$user_id = $data['user_id'];
$files = $request->getUploadedFiles();
if (empty($files['newfile'])) {
throw new Exception('Expected a newfile');
}
$newfile = $files['newfile'];
if ($newfile->getError() === UPLOAD_ERR_OK) {
$uploadFileName = "profileImage".$user_id.".jpg";
$newfile->moveTo("/path/to/image/$uploadFileName");
}
$database->query("UPDATE `users` SET `profile_image_url` = :image WHERE user_id = :user_id");
$database->bind(':image', $uploadFileName);
$database->bind(':user_id', $user_id);
$database->execute();
$Jsonarray['status'] = "true";
$Jsonarray['message'] = "Image Uploaded Successfully";
return $response->withStatus(200)->withHeader('Content-Type', 'application/json')->write(json_encode($Jsonarray));
});
Weird thing is that Alamofire outputs status code 500 but the server do not tell me nothing about it. The problem must be in the Swift part. So I do not know even how to debug it.
How should I solve the problem?
I solved the problem. I rebuilt it that way:
Convert image to Base64 String on client
Decode it to image on backend
Upload it
So in Swift I Convert it like this:
let chosenProfileImage = info[UIImagePickerControllerEditedImage] as! UIImage
let imageData = UIImageJPEGRepresentation(chosenProfileImage, 0.2)
profileImageView.image = chosenProfileImage
let base64String = imageData?.base64EncodedString(options: .lineLength64Characters)
And backend is pretty much same, just converted it back to file using base64_decode(); and used file_put_contents(); function to move it to server.
I've looked up other solutions to this question but I don't fully understand what they're doing, and I can't get mine to work.
Here's my swift code
let imageData = UIImageJPEGRepresentation(image, 1.0)
if(imageData == nil ) { return }
let request = NSMutableURLRequest(URL: NSURL(string: ip)!) //ip is a string variable holding my correct ip address
request.HTTPMethod = "POST"
request.setValue("Keep-Alive", forHTTPHeaderField: "Connection")
let postString = "id=\(id)&"
let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: configuration, delegate: self, delegateQueue: NSOperationQueue.mainQueue())
let body = NSMutableData()
body.appendData(postString.dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(imageData!)
request.HTTPBody = body
let task = session.uploadTaskWithRequest(request, fromData: imageData!)
task.resume()
And here's my PHP file
<?php
if (move_uploaded_file($_FILES['file']['tmp_name'], "image.jpg")) {
echo "File uploaded: ".$_FILES["file"]["name"];
}
else {
echo "File not uploaded";
}
?>
I have valid read and write access to the "image.jpg" file which sits on the front of my server, but it will still say that it could not upload the file. Any thoughts?
You're submitting the image as part of the POST request body. It won't be accessible using $_FILES.
You can Base-64 encode the image data, send the post string "id=\(id)&image=\(base64EncodedImageData)", then retrieve and decode it using $_POST.
You may want to consider using a networking library like Alamofire.
The manual and not recommended way: Change your PHP code to generate JSON responses.
echo json_encode(array("success" => true,
"filename" => basename($_FILES['image']['name']));
But as was mentioned you should let Alamofire do that for you. You can use MSProgress for a visual progress update in Alamofire.
let apiToken = "ABCDE"
Alamofire.upload(
.POST,
"http://sample.com/api/upload",
multipartFormData: { multipartFormData in
multipartFormData.appendBodyPart(data: imageData, name: "yourParamName", fileName: "imageFileName.jpg", mimeType: "image/jpeg")
multipartFormData.appendBodyPart(data: apiToken.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"api_token")
multipartFormData.appendBodyPart(data: otherBodyParamValue.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)!, name :"otherBodyParamName")
},
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
print("Uploading Avatar \(totalBytesWritten) / \(totalBytesExpectedToWrite)")
dispatch_async(dispatch_get_main_queue(),{
/**
* Update UI Thread about the progress
*/
})
}
upload.responseJSON { (JSON) in
dispatch_async(dispatch_get_main_queue(),{
//Show Alert in UI
print("Avatar uploaded");
})
}
case .Failure(let encodingError):
//Show Alert in UI
print("Avatar uploaded");
}
}
);
I'm using this code (Swift) to upload an image that user selected from their photos to a server:
let imageFormatted = UIImageJPEGRepresentation(imageView.image!, 0.5);
let uuid = NSUUID().UUIDString
print ("MARK -- UUID is " + uuid)
Alamofire.upload(
.POST,
"http://www.memer.onlie/upload.php",
multipartFormData: { multipartFormData in
multipartFormData.appendBodyPart(data: imageFormatted!, name: "imagefile",
fileName: uuid + ".jpg", mimeType: "image/jpeg")
},
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.validate()
upload.responseJSON { response in
dispatch_async(dispatch_get_main_queue()) {
self.displayAlert("Uploaded!", message: "Your meme was uploaded, and you might see it in the app soon!", responseButtonText: "<3")
}
var json = JSON(data: response.data!)
print ("MARK -- JSON response: " + json["response"].stringValue)
}
print ("MARK -- Upload success!")
case .Failure(let encodingError):
print(encodingError)
print ("MARK -- Upload failure!")
self.displayAlert("Issue uploading.", message: "There was an issue uploading your meme.", responseButtonText: "Aww :(")
}
}
)
No image is being uploaded to the server. What can I correct to get this to work?
Edited code.
This thread helps you understand what you have not considered and what you need to do to solve the issue. I guess you need to set request header and body part properly. If you use Alamofire and have to use 'multipart/form-data' encoding type, you can write code like this.
Alamofire.upload(.POST, destURL, headers: yourHeader, multipartFormData: { multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 0.5) {
multipartFormData.appendBodyPart(data: imageData, name:"file", fileName: "imagefile", mimeType: "image/jpg")
}
// Append parameters you should send
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.validate()
upload.responseJSON { response in
// do something if response is success
}
case .Failure(_):
// do something if response is fail
}
})
I'm trying to upload UIImage to a server via a web api. I'm creating my web rest API with laravel 5.2.
Here is my function in Swift which should make a post request to my API with the UIImage and some parameters:
func uploadWithAlamofire(imageUpload: UIImage) {
let image = imageUpload
// define parameters
let parameters = [
"hometown": "abc",
"living": "abc"
]
// Begin upload
Alamofire.upload(.POST, "http://localhost:8888/buyIT/public/app/api/createPost",
// define your headers here
headers: ["Authorization": "auth_token"],
multipartFormData: { multipartFormData in
// import image to request
if let imageData = UIImageJPEGRepresentation(image, 1) {
multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "myImage.png", mimeType: "image/png")
}
// import parameters
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
},
// you can customise Threshold if you wish. This is the alamofire's default value
encodingMemoryThreshold: Manager.MultipartFormDataEncodingMemoryThreshold,
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.responseJSON { response in
print(response)
}
case .Failure(let encodingError):
print(encodingError)
}
})
}
But I don't know how to get the image and then upload it to my server.
Here is what I tried in my web api:
public function createPost(Request $request)
{
$file = $request->input('file');
$input = $request->only('hometown');
//Create deals folder if not exist
if (!file_exists('Upload/images')) {
mkdir('Upload/images', 0777, true);
}
if(file_exists('Upload/images'))
{
// SET UPLOAD PATH
$destinationPath = 'Upload/images';
// GET THE FILE EXTENSION
if ($file != null) {
$extension = $file->getClientOriginalExtension();
// RENAME THE UPLOAD WITH RANDOM NUMBER
$fileName = rand(11111, 99999) . '.' . $extension;
// MOVE THE UPLOADED FILES TO THE DESTINATION DIRECTORY
$upload_success = $file->move($destinationPath, $fileName);
//$filePath = url('/').'/'.$destinationPath.'/'.$fileName;
if($upload_success)
{
return "success";
}
else {
return "failed !!!";
}
}
}
else
{
return "failed";
}
return $file;
}
Or , You can use AlamoFire
func createMultipart(image: UIImage, callback: Bool -> Void){
// use SwiftyJSON to convert a dictionary to JSON
var parameterJSON = JSON([
"id_user": "test"
])
// JSON stringify
let parameterString = parameterJSON.rawString(encoding: NSUTF8StringEncoding, options: nil)
let jsonParameterData = parameterString!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
// convert image to binary
let imageData = UIImageJPEGRepresentation(image, 0.7)
// upload is part of AlamoFire
upload(
.POST,
URLString: "http://httpbin.org/post",
multipartFormData: { multipartFormData in
// fileData: puts it in "files"
multipartFormData.appendBodyPart(fileData: jsonParameterData!, name: "goesIntoFile", fileName: "json.txt", mimeType: "application/json")
multipartFormData.appendBodyPart(fileData: imageData, name: "file", fileName: "iosFile.jpg", mimeType: "image/jpg")
// data: puts it in "form"
multipartFormData.appendBodyPart(data: jsonParameterData!, name: "goesIntoForm")
},
encodingCompletion: { encodingResult in
switch encodingResult {
