ERR : failure(Alamofire.AFError.responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength))
I tried using .responseString after googling about this error, but the error was not resolved.
My code is
AF.upload(multipartFormData: { (multipartFormData) in
for image in files {
if let image = image.jpegData(compressionQuality: 1) {
multipartFormData.append(image, withName: "files", fileName: "\(files).jpg", mimeType: "image/jpeg") // jpeg 파일로 전송
}
}
for (key, value) in params {
multipartFormData.append("\(value)".data(using: .utf8, allowLossyConversion: false)!, withName: "\(key)")
}
}, to: Constant.domainURL + "/product/write"
,method: .post
,headers: header).responseString { (response) in
print(response)
if let err = response.error{
print(err)
return
}
print("success")
}
Please help me.....

I am beginner iOS developer and I don't know how to upload a file using Alamofire 5, I know there are a lot of similar questions, but all the topics here are from very old versions and I couldn't get it working. I tried this code, but I couldn't fit to my case, it gives me success, but file is not uploaded and the result I get is not what I get in postman. This is the code:
func uploadFile(_ parameters: Parameters) {
AF.upload(multipartFormData: { multipartFormData in
URLEncoding.default.queryParameters(parameters).forEach { (key, value) in
if let data = value.data(using: .utf8) {
multipartFormData.append(data, withName: key)
}
}
}, to: url)
.responseDecodable(of: FileCreation.self) { response in
switch response.result {
case .success(let data):
print(data, "success")
case .failure(let error):
print(error)
}
}
}
usage:
#IBAction func upload(_ sender: UIButton) {
guard let data = image?.jpegData(compressionQuality: 0.5)! else { return }
let parameters = ["addFiles": data]
uploadFile(parameters)
}
Here's Xcode output:
Here you can see postman response after I upload file:
Alamofire.upload(multipartFormData: {
multipartFormData in
if let imageData = image[0].jpegData(compressionQuality: 0.6) {
multipartFormData.append(imageData, withName: "addFiles", fileName: "file.pdf", mimeType: "application/pdf")
}
for (key, value) in param {
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
},to: apiurl, method: .post, headers: headers, encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON {
response in
print(response.result)
}
//break
case .failure(let encodingError):
break
}
})
Try This
func uploadFilesToServer(_ url: String, method: HTTPMethod, parameters: [String:Any]?, file: [String:Any]?, fileType: String, fileName: String, headers:HTTPHeaders?, completionHandler: #escaping (_ result: Data?, _ success: Bool, _ status: String) -> ()) {
var status = Bool()
var message = String()
let url = URL(string: url)
AF.upload(multipartFormData: { multiPart in
if let files = file {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy-hh-mm-ss"
let dateString = dateFormatter.string(from: Date())
for (key, value) in files {
if fileType == "pdf" {
let filePath = URL(fileURLWithPath: value as! String)
multiPart.append(filePath, withName: "\(key)", fileName: fileName, mimeType: "file/pdf")
} else {
multiPart.append(value as! Data, withName: "\(key)", fileName: "Uploads\(dateString).png", mimeType: "image/png")
}
}
}
if let params = parameters {
for (key, value) in params {
multiPart.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
}
}, to: url!, method: method, headers: headers ?? nil)
.validate()
.uploadProgress(closure: { progress in
print(progress)
})
.responseJSON { response in
switch response.result {
case .success(let responseData):
print(responseData)
case .failure(let networkErr):
switch networkErr {
case .responseSerializationFailed(reason: _):
message = "Something went wrong"
case .sessionTaskFailed(error: let err):
message = err.localizedDescription
default:
message = "Something went wrong"
}
completionHandler(nil, false, message)
break
}
}
}
usage
uploadFilesToServer(url, method: .post, parameters: params, file: uploadFile, fileType: "pdf", fileName: fileNme, headers: tokenHeader) { [self] responseData, isSuccess, responseMsg in
if isSuccess {
} else {
}
}
I have a postman api that requires an Extension to send with the image. Without the extension it take the image as a file. Help me to send the image with the extension or tell me the better way to do so, or let me know where i am doing wrong.Postman Image Here is my code so far:
func UPLOD(){
guard let token = UserDefaults.standard.string(forKey: "accesstoken") else {
return
}
print("Create button ACCESS KEY::::- \(token)")
let headers: HTTPHeaders = [
"x-access-token": token,
"Content-type": "multipart/form-data",
"Content-Disposition" : "form-data",
"Filename" : "Angle",
"Ext" : ".png"
]
let image = myImageView.image
let imgData = image!.jpegData(compressionQuality: 0.7)!
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imgData, withName: "FileToUpload", fileName: "swift_file.png", mimeType: "image/png")
print("mutlipart 1st \(multipartFormData)")
multipartFormData.append("angela".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName :"Filename")
multipartFormData.append("Image".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName :"Folder")
//multipartFormData.append("jpeg".data(using: String.Encoding.utf8, allowLossyConversion: false)!, withName :"Ext")
//multipartFormData.append(imgData, withName: "Ext", mimeType: "image/png")
}, to:"http://192.168.80.21:8800/api/v1/upload/uploadfile", method:.post, headers:headers)
{
(result) in
switch result {
case .success(let upload, _, _):
print("x:::::::::\(result)")
print("Upload;;\(upload)")
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress)")
})
upload.validate(statusCode: 200..<300)
upload.responseJSON { response in
guard response.error == nil else {
print("Pre json\(response as Any)")
let json = JSON(response)
print("JSON: \(json)")
return
}
print(response.result.value as Any)
print("Response: \(JSON(response.data as Any))")
}
case .failure(let encodingError):
print(encodingError)
}
}

I am trying to upload an image using swift to the server. i tried NSMutableURLRequest with URLSession. i received network connection lost. I thought it will be a better way to simply use Alamofire but got into a problem as xcode doesn't find the function update.
Any idea how to upload image with Alamofire? or find the update func?
the code for alamofire:
func uploadImageWithAlmofire(url: String) {
let params: Parameters = ["name": "abcd", "gender": "Male"]
Alamofire.upload(multipartFormData:
{
(multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(self.yourimageView.image!, 0.1)!, withName: "file", fileName: "file.jpeg", mimeType: "image/jpeg")
for (key, value) in params
{
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
}, to:url,headers:nil)
{ (result) in
switch result {
case .success(let upload,_,_ ):
upload.uploadProgress(closure: { (progress) in
//Print progress
})
upload.responseJSON
{ response in
//print response.result
if response.result.value != nil
{
let dict :NSDictionary = response.result.value! as! NSDictionary
let status = dict.value(forKey: "status")as! String
if status=="1"
{
print("DATA UPLOAD SUCCESSFULLY")
}
}
}
case .failure(let encodingError):
break
}
}
}
When you check Uploading Data to a Server example, it uses AF instead of Alamofire:
AF.upload(multipartFormData: { multipartFormData in
multipartFormData.append(Data("one".utf8), withName: "one")
multipartFormData.append(Data("two".utf8), withName: "two")
}, to: "https://httpbin.org/post")
.responseJSON { response in
debugPrint(response)
}
Try with this
AF.upload(multipartFormData: { multipartFormData in
multipartFormData.append(Data(self.businessType.utf8), withName: "business_type")
let theFileName1 = (self.doc1.absoluteString as NSString).lastPathComponent
multipartFormData.append(self.doc1, withName: "key_value", fileName: theFileName1, mimeType: "image/png")
}, to: "https://www.test_document.php") //POST URL
.responseJSON { response in
debugPrint(response)
}
How to handle multipart in swift if you are dealing with multiple images having different keys and also having parameter dictionary with different kinds of key:value pairs like "String":"Any", "String":"[Any]", [[String:Any]].
let headers: HTTPHeaders = ["Content-type": "multipart/form-data"]
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in parameters {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key as String)
}
//Todo: - Images
var c = 0
for dictImage in arrImage {
let validDict = kSharedInstance.getDictionary(dictImage)
for keyName in validDict.keys {
print(keyName)
//Incr
c += 1
if let imageData = validDict[keyName] as? Data {
multipartFormData.append(imageData, withName: "\(keyName)", fileName: "\(Date().timeIntervalSince1970).jpeg", mimeType: "image/jpeg")
}
}
}
}, usingThreshold: UInt64(), to: urlString, method: .post, headers: headers) { (result) in
switch result{
case .success(let upload, _, _):
upload.responseJSON { response in
print("Succesfully uploaded")
if((response.result.value) != nil) {
debugPrint(response.result.value!)
let jsonData = JSON(response.result.value!)
if jsonData["status"].bool == true {
completion(jsonData.dictionaryObject!, true)
}else
{
completion(jsonData.dictionaryObject!, false)
}
}
}
case .failure(let error):
print("Error in upload: \(error.localizedDescription)")
failure(error, false)
}
}
Please check below code. Hope it helps you
Alamofire.upload(
multipartFormData: { MultipartFormData in
for (key, value) in parameters {
MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
for i in 0 ..< files.count {
let fileName : String = "image\(i).jpg"
let datum : Data = files[i]
MultipartFormData.append(datum, withName: fileParamName, fileName: fileName, mimeType: "image/jpg")
}
}, to: URLString, method: .post, headers: headers) { (result) in
switch(result) {
case .success(let upload, _, _):
upload.responseJSON { response in
}
break;
case .failure(_):
}
}
I'm working with Swift 4 and Alamofire 5, I upload two multibart photos and I want to print the progress
AF.upload(
multipartFormData: { MultipartFormData in
MultipartFormData.append(firstPic, withName: "first_pic", fileName: "image.jpeg", mimeType: "image/jpeg")
MultipartFormData.append(secondPic, withName: "second_pic", fileName: "image.jpeg", mimeType: "image/jpeg")
}, to: urlString, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
print(totalBytesRead)
}
upload.responseJSON { request, response, result in
print(result)
}
case .Failure(let encodingError):
print(encodingError)
}
})
and this gets an error saying
Argument labels '(multipartFormData:, to:, encodingCompletion:)' do not match any available overloads
did the library update the code or something??
Please modify according to your need
func upload(image: Data, to url: Alamofire.URLRequestConvertible, params: [String: Any]) {
AF.upload(multipartFormData: { multiPart in
for (key, value) in params {
if let temp = value as? String {
multiPart.append(temp.data(using: .utf8)!, withName: key)
}
if let temp = value as? Int {
multiPart.append("\(temp)".data(using: .utf8)!, withName: key)
}
if let temp = value as? NSArray {
temp.forEach({ element in
let keyObj = key + "[]"
if let string = element as? String {
multiPart.append(string.data(using: .utf8)!, withName: keyObj)
} else
if let num = element as? Int {
let value = "\(num)"
multiPart.append(value.data(using: .utf8)!, withName: keyObj)
}
})
}
}
multiPart.append(image, withName: "file", fileName: "file.png", mimeType: "image/png")
}, with: url)
.uploadProgress(queue: .main, closure: { progress in
//Current upload progress of file
print("Upload Progress: \(progress.fractionCompleted)")
})
.responseJSON(completionHandler: { response in
//Do what ever you want to do with response
if let error = response.error {
print(error)
}
guard let data = response.value else {
return
}
print(value)
})
}
Alamofire 5 no longer requires an encodingCompletion! Instead, multipart form encoding is done as part of the standard now-asynchronous request process and will return errors on the Request, and they're available during validate and response* calls.
let headers: HTTPHeaders = [
/* "Authorization": "your_access_token", in case you need authorization header */
"Content-type": "multipart/form-data"
]
AF.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(imageOrVideo!.jpegData(compressionQuality: 0.5)!, withName: "upload_data" , fileName: "file.jpeg", mimeType: "image/jpeg")
},
to: "http://----/new.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
