this is my code that I want to upload image to server using Alamofire, it not error but it can't push image to server. what should I do ? Thank in advance.
let url = URL(string: urlString)!
var urlRequest = URLRequest(url: url)
urlRequest.httpMethod = "POST"
let parameters = ["name": rname]
do {
urlRequest.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: [])
} catch {
print(error)
}
urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
let image = UIImage.init(named: "myImage")
let imgData = UIImageJPEGRepresentation(image!, 0.2)!
Alamofire.upload(multipartFormData: { MultipartFormData in
MultipartFormData.append(imgData, withName: "fileset", fileName: "name", mimeType: "image/jpg")
},with: urlRequest,encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
if let info = response.result.value as? Dictionary<String, AnyObject> {
if let links = info["links"] as? Dictionary<String, AnyObject> {
if let imgLink = links["image_link"] as? String {
print("LINK: \(imgLink)")
}
}
}
} case .failure(let error):
print(error)
}
})

Try below code
let image = UIImage.init(named: "myImage")
let imgData = UIImageJPEGRepresentation(image!, 0.2)!
let parameters = ["name": rname] //Optional for extra parameter
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imgData, withName: "fileset",fileName: "file.jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
} //Optional for extra parameters
},
to:"mysite/upload.php")
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON { response in
print(response.result.value)
}
case .failure(let encodingError):
print(encodingError)
}
}

let params: Parameters = ["name": "abcd" "gender": "Male"]
Alamofire.upload(multipartFormData:
{
(multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(self.yourimageView.image!, 0.1)!, withName: "image", 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:yourUrl,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
}
}
Need to specify name, fileName, mimeType, these are important to many servers
func upload(image: UIImage, completion: (URL?) -> Void) {
guard let data = UIImageJPEGRepresentation(image, 0.9) else {
return
}
Alamofire.upload(multipartFormData: { (form) in
form.append(data, withName: "file", fileName: "file.jpg", mimeType: "image/jpg")
}, to: "https://yourawesomebackend.com", encodingCompletion: { result in
switch result {
case .success(let upload, _, _):
upload.responseString { response in
print(response.value)
}
case .failure(let encodingError):
print(encodingError)
}
})
}
Try below code For MultipleImage Upload. asked by @Saurabh.
However it is better to make upload 1 by 1 instead of uploading all at once.
because if it failed, it will only failed on 1 image. but upload all at once.if 1 file failed user need to restart the uploading process from the beginning.
nevertheless here is what you going have to do if you want to upload multiple data at once.
let image1 = UIImage.init(named: "myImage1")
let image2 = UIImage.init(named: "myImage2")
let image3 = UIImage.init(named: "myImage3")
let image4 = UIImage.init(named: "myImage4")
let imgData1 = UIImageJPEGRepresentation(image!, 0.2)!
let imgData2 = UIImageJPEGRepresentation(image!, 0.2)!
let imgData3 = UIImageJPEGRepresentation(image!, 0.2)!
let imgData4 = UIImageJPEGRepresentation(image!, 0.2)!
let parameters = ["name": rname] //Optional for extra parameter
Alamofire.upload(multipartFormData: { multipartFormData in
//loop this "multipartFormData" and make the key as array data
multipartFormData.append(imgData1, withName: "fileset[0]",fileName: "file.jpg", mimeType: "image/jpg")
multipartFormData.append(imgData2, withName: "fileset[1]",fileName: "file.jpg", mimeType: "image/jpg")
multipartFormData.append(imgData3, withName: "fileset[2]",fileName: "file.jpg", mimeType: "image/jpg")
multipartFormData.append(imgData4, withName: "fileset[3]",fileName: "file.jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
} //Optional for extra parameters
},
to:"mysite/upload.php")
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON { response in
print(response.result.value)
}
case .failure(let encodingError):
print(encodingError)
}
}
Noted: multipartFormData are using append meaning it is an Array of request. you can loop and append more if needed.
Ok Bro I use this code with Swift 4 and Alamofire
import Foundation
import Alamofire
class UploadImageController: NSObject {
// MARK: - shared
static let shared = UploadImageController()
// MARK: - init
let decoder = JSONDecoder()
// MARK: - uploadImageOnly
func uploadImageWith(endUrl: String, photo: UIImage?, parameters: [String : Any]?, headers: HTTPHeaders?, completion: @escaping (_ success: Bool, _ uploadImageResponse: UploadImageResponse?) -> Void ) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
if let data = UIImageJPEGRepresentation(photo!, 0.5) {
multipartFormData.append(data, withName: "invoice", fileName: "invoice.jpeg", mimeType: "invoice/jpeg")
}
}, usingThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold, to: endUrl, method: .post, headers: headers) { (result) in
switch result {
case .failure(let error):
print("UploadImageController.requestWith.Alamofire.usingThreshold:", error)
completion(false, nil)
case .success(request: let upload, streamingFromDisk: _, streamFileURL: _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON(completionHandler: { (response) in
switch response.result {
case .failure(let error):
print("UploadImageController.requestWith.Alamofire.upload.responseJSON:", error)
completion(false, nil)
case .success( _):
print("UploadImageController.requestWith.Alamofire.upload.responseJSON Succes")
guard let data = response.data else { return }
do {
let uploadImageResponse = try self.decoder.decode(UploadImageResponse.self, from: data)
completion(true, uploadImageResponse)
} catch let jsonError {
print("Error serializing json.ProfileController.getProfile:", jsonError)
completion(false, nil)
}
}
})
}
}
}
// MARK: - uploadImageWithParameters
func uploadImageWithParametersAnd(endUrl: String, photo: UIImage?, parameters: [String : Any]?, headers: HTTPHeaders?, completion: @escaping (_ success: Bool, _ addInvoiceResponse: AddInvoiceResponse?) -> Void ) {
Alamofire.upload(multipartFormData: { (multipartFormData) in
if let data = UIImageJPEGRepresentation(photo!, 0.5) {
multipartFormData.append(data, withName: "invoicePicture", fileName: "invoicePicture.jpeg", mimeType: "invoice/jpeg")
}
for (key, value) in parameters! {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: "\(key)")
}
}, usingThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold, to: endUrl, method: .post, headers: headers) { (result) in
switch result {
case .failure(let error):
print("UploadImageController.requestWith.Alamofire.usingThreshold:", error)
completion(false, nil)
case .success(request: let upload, streamingFromDisk: _, streamFileURL: _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON(completionHandler: { (response) in
switch response.result {
case .failure(let error):
print("UploadImageController.requestWith.Alamofire.upload.responseJSON:", error)
completion(false, nil)
case .success( _):
print("UploadImageController.requestWith.Alamofire.upload.responseJSON Succes")
guard let data = response.data else { return }
do {
let addInvoiceResponse = try self.decoder.decode(AddInvoiceResponse.self, from: data)
completion(true, addInvoiceResponse)
} catch let jsonError {
print("Error serializing json.ProfileController.getProfile:", jsonError)
completion(false, nil)
}
}
})
}
}
}
}
For example this AddInvoiceResponse
import Foundation
struct AddInvoiceResponse: Decodable {
let id, message: String?
}
and here UploadImageResponse
import Foundation
struct UploadImageResponse: Codable {
let id, message: String?
}
let url = BaseViewController.API_URL + "uploads"
let image = info[UIImagePickerControllerEditedImage] as? UIImage
let imgData = UIImageJPEGRepresentation(image!, 0.2)!
let parameters = [
"user_id" : UserDefaults.standard.value(forKey: "userId")!
]
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imgData, withName: "uload_data",fileName: "file.jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
} //Optional for extra parameters
},
to:url)
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})
upload.responseJSON { response in
self.objHudHide()
print(response.result.value)
let jsonDict : NSDictionary = response.result.value as! NSDictionary
print(jsonDict)
if jsonDict["status"] as! String == "Success"
{
let detailDict : Dictionary = jsonDict["detail"] as! Dictionary<String,Any>
if let getTotalPrice = detailDict["total_price"]
{
self.lblTotalPrice.text = "$ \(getTotalPrice) + Free Shipping"
}
if let getTotalSize = detailDict["total_upload_size"]
{
self.lblTotalSize.text = "Total Size : \(getTotalSize)"
}
}
else
{
let alertViewController = UIAlertController(title: NSLocalizedString("Alert!", comment: ""), message:"Something Went wrong please try again." , preferredStyle: .alert)
let okAction = UIAlertAction(title: NSLocalizedString("Ok", comment: ""), style: .default) { (action) -> Void in
}
alertViewController.addAction(okAction)
self.present(alertViewController, animated: true, completion: nil)
}
}
case .failure(let encodingError):
print(encodingError)
}
}
The only one working for me at this date:
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://35.227.31.145/new.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
Updated code to Swift 5.
In swift 5 there is a change in this line
let imageData = UIImageJPEGRepresentation(image!, 0.2)!
To like this
let imageData = image.jpegData(compressionQuality: 0.50)
Whole code to upload image
let param: [String:Any] = ["your_parameters"]
var image = UIImage()
image = UIImage(named: "edit.png")!
let imageData = image.jpegData(compressionQuality: 0.50)
print(image, imageData!)
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imageData!, withName: "file", fileName: "swift_file.png", mimeType: "image/png")
for (key, value) in param {
multipartFormData.append("\(value)".data(using: String.Encoding.utf8)!, withName: key)
}
}, to: "your_url")
{ (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
//Print progress
print("uploading \(progress)")
})
upload.responseJSON { response in
//print response.result
}
case .failure( _): break
//print encodingError.description
}
}
}
user_photo is key for dic
swift_file.jpg is value for value
Write the same withName is key
Write the same fileName is value
call the UploadImage(Image)
func UploadImage(img:UIImage) {
let urlfinal = “ananda.profile.php";
let parameters = ["user_id":"531", "user_photo”: "swift_file.jpg"]
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(img, 1)!, withName: "user_photo", fileName: "swift_file.jpeg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
print(multipartFormData)
}, to:urlfinal)
{ (result) in
switch result {
case .success(let upload, , ):
upload.uploadProgress(closure: { (progress) in
})
upload.responseJSON { response in
print(response)
}
case .failure( _): break
}
}
}
