I try to create multipart request using Alamofire 4.
I wont to add [String: AnyObject] as part. But when multipartFormData appending bool or [Int] from my payload dict app crashed! Where is my mistake?
let payload: [String: AnyObject] = [
"key1": "val1" as AnyObject,
"key2": true as AnyObject,
"key3" : [1,2,3,4] as AnyObject
]
let requestString = "http://www.url.com/api/action"
Alamofire.upload(multipartFormData: { (multipartFormData) in
for (key, value) in payload {
multipartFormData.append(value.data(using: String.Encoding.utf8.rawValue, allowLossyConversion: false)!, withName: "request", fileName: key, mimeType: "application/json")
}
multipartFormData.append(imageUrl, withName: "fileData", fileName: "image", mimeType: "image/png")
}, to: requestString, method: .post , headers: ["Content-Type": "multipart/form-data"], encodingCompletion: { (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print(progress.fractionCompleted * 100)
})
upload.responseJSON(completionHandler: { (response) in
})
case .failure(let error):
print(error)
}
})
You are sending wrong param. Try below code for Alamofire 4.
let payload: [String: AnyObject] = [
"key1": "val1" as AnyObject,
"key2": true as AnyObject,
"key3" : [1,2,3,4] as AnyObject
]
let requestString = "http://www.url.com/api/action"
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(UIImageJPEGRepresentation(self.photoImageView.image!, 0.5)!, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
for (key, value) in payload {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
}, to: requestString, method: .post , headers:nil, encodingCompletion: { (result) in
switch result {
case .success(let upload, _, _):
upload.uploadProgress(closure: { (progress) in
print(progress.fractionCompleted * 100)
})
upload.responseJSON(completionHandler: { (response) in
})
case .failure(let error):
print(error)
}
})

In my code the drag&drop function works fine with URL objects. But the exact same code for String objects does not. I have tried with countless casts and loadItem instead of loadObject ... no luck so far.
Can anyone help me here? It would be very much appreciated.
code for URL objects – Working
.onDrag {
return NSItemProvider(object: item.url as NSURL)
}
.onDrop(of: [UTType.url], isTargeted: $isDropping) { providers in
_ = providers.first?.loadObject(ofClass: URL.self) { url, error in
if let error = error { print(error.localizedDescription) }
if let url = url {
DispatchQueue.main.async {
self.array2.insert(Item(title: "new", url: url), at: 0)
}
}
}
return true
}
the same with String does not:
.onDrag {
return NSItemProvider(object: item.title as NSString)
}
.onDrop(of: [UTType.text], isTargeted: $isDropping) { providers in
_ = providers.first?.loadObject(ofClass: String.self) { string, error in
if let error = error { print(error.localizedDescription) }
if let string = string {
DispatchQueue.main.async {
self.array2.insert(Item(title: string, url: URL(string: "http://www.apple.com")!), at: 0)
}
}
}
return true
}
full MRE code:
import SwiftUI
import UniformTypeIdentifiers
struct Item: Identifiable {
let id = UUID()
var title: String
var url: URL
}
struct ContentView: View {
#State var array1: [Item] = [
Item(title: "One", url: URL(string: "http://www.amazon.com")!),
Item(title: "Two", url: URL(string: "http://www.apple.com")!),

ForEach(array1) { item in
Text(item.title)
Text(item.url.absoluteString).foregroundColor(.secondary)
// DRAG

}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.background(isDropping ? .green : .gray)
// DROP with url/NSURL -- WORKS

}
As always thanks to #Asperi and his answer here:
SwiftUI: Not getting dropped NSString value in DropDelegate
This now works:
.onDrop(of: [UTType.utf8PlainText], isTargeted: $isDropping) { providers in
_ = providers.first?.loadItem(forTypeIdentifier: "public.utf8-plain-text") { data, error in
if let error = error { print(error.localizedDescription) }
if let data = data as? Data {
DispatchQueue.main.async {
let string = NSString(data: data, encoding: 4) ?? "failed"
print(string)
self.array2.insert(Item(title: string as String, url: URL(string: "http://www.apple.com")!), at: 0)
}
}
}
return true
}
Folks, The following works except for the catch, xcode errors out with expected member name following '.'
Is this the proper way to promisify with PromiseKit?
All suggestions welcome! Thanks!
#IBAction func loginButtonTapped(sender: AnyObject) {

NSUserDefaults.standardUserDefaults().setBool(true, forKey: "isUserLoggedIn")
NSUserDefaults.standardUserDefaults().synchronize()
self.dismissViewControllerAnimated(true, completion: nil)
} else {
let myAlert = UIAlertController(title: "Alert", message: message, preferredStyle: UIAlertControllerStyle.Alert)
let okAction = UIAlertAction(title: "Try Again", style: UIAlertActionStyle.Default, handler: nil)
myAlert.addAction(okAction)

I managed to upload file with multipart-form-data Alamofire upload:
Alamofire.upload(.POST, "api.myservice.com", headers: myheaders, multipartFormData: { (multipartFormData:MultipartFormData) -> Void in
multipartFormData.appendBodyPart(data: json, name: "metadata", mimeType: "application/json")
multipartFormData.appendBodyPart(data: self.data, name: "document", fileName: "photo.png", mimeType: "image/png")
}, encodingMemoryThreshold: 10 * 1024 * 1024) { (result:Manager.MultipartFormDataEncodingResult) -> Void in
}
but I can't see a way to track upload progress and have completion block called after upload is completed (or failed). Is there a way to do this in Alamofire?
Note: I am aware that uploading with progress is possible, but I'm looking into multipart-form-data specifically.
Here is a way to have completion, failure and progress closures (thanks to my colleague for point me to the solution):
Alamofire.upload(.POST, absPath(), headers: headers(), multipartFormData: { (multipartFormData:MultipartFormData) -> Void in
multipartFormData.appendBodyPart(data: json, name: "metadata", mimeType: "application/json")
multipartFormData.appendBodyPart(data: self.data, name: "document", fileName: "photo.png", mimeType: "image/png")
}, encodingMemoryThreshold: 10 * 1024 * 1024, encodingCompletion: { (encodingResult) -> Void in
switch encodingResult {
case .Success(let upload, _, _):
upload.responseJSON { response in
// success block
}
upload.progress { _, totalBytesRead, totalBytesExpectedToRead in
let progress = Float(totalBytesRead)/Float(totalBytesExpectedToRead)
// progress block
}
case .Failure(_):
// failure block
}
})
The accepted answer is great. This one includes parameters, too:
let image = UIImage(named: "big.jpg")!
let imageData = UIImageJPEGRepresentation(image, 1)
let coupon = textBox?.text ?? "NO coupon"
let uploadUrl = "http://example.com/upload.php"
// define parameters
let parameters : [String: String] = ["one":"some param", "two":"some other param"]
Alamofire.upload(.POST, uploadUrl, headers: nil,
multipartFormData: { multipartFormData in
multipartFormData.appendBodyPart(data: imageData!, name: "cannotBeBlank", fileName: "image.zip", mimeType: "image/png")
// import parameters
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.data!, name: key)
}
}, encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.progress { bytesWritten, totalBytesWritten, totalBytesExpectedToWrite in
print("1) \(bytesWritten) 2) \(totalBytesWritten) 3) \(totalBytesExpectedToWrite)")
// This closure is NOT called on the main queue for performance
// reasons. To update your ui, dispatch to the main queue.
dispatch_async(dispatch_get_main_queue()) {
print("Total bytes written on main queue: \(totalBytesWritten)")
}
}
upload.responseData(self.handleResponse)
case .Failure:
self.handleError()
}
})
This code work before migrate to Swift 2.0 and Alamofire 2.0
manager.upload(requestMethod, NSURL(string: url)!, multipartFormData: { multipartFormData in
for param in params {
multipartFormData.appendBodyPart(data: param.1.dataUsingEncoding(NSUTF8StringEncoding)!, name: param.0)
}
multipartFormData.appendBodyPart(data: imageData!, name: "file", fileName: "tempImage", mimeType: "image/*") },
encodingCompletion: { encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.responseJSON { _, response, result in
switch result {
case .Success(let data):
...
case .Failure(let encodingError):
...
}
}
case .Failure(let encodingError):
...
}
} )
Now the line:
upload.responseJson...
always return fail "FAILURE: Error Domain=NSURLErrorDomain Code=-999 "cancelled" "
Someone has managed to use the multipart in Alamofire 2.0 successfully and know what am I doing wrong?
In my case it had to do with additional headers. I put general headers like this:
var defaultHeaders = Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders ?? [:]
defaultHeaders["User-Agent"] = userAgent
if let ip = ifAddress {
defaultHeaders["X-Forwarded-For"] = ip
}
let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.HTTPAdditionalHeaders = defaultHeaders
manager = Alamofire.Manager(configuration: configuration)
And for additional headers that depend on a specific condition I put in the request itself:
if condition {
headers = ["Accept": contentType]
}
manager!.request(requestMethod, url, parameters: params, headers: headers).responseJSON { response in

I am developing an iPhone application with swift. and I'am using Alamofire framework for handling http requests. I use Alamofire.request for POST , GET and etc like this:
Alamofire.request(.POST, myURL , parameters: ["a": "1", "b" : "2" ])
.response { (request, response, data, error) in
}
And I use Alamofire.upload to upload image to server this :
Alamofire.upload(.POST, uploadURL , fileURL)
And both works perfectly, but now I want to upload an image and also send some parameters with, and my content type should be multipart/form-data and Alamofire.upload does not accept parameters.
There are two more question on SO about this issue with swift, which first one is not using Alamofire (and really, why not?) and in second one, mattt (Alamofire Developer) cited to use encoding parameters.
I checked his example, but still couldn't figure out how to do that.
Can any one please help me solve this problem?
Thank you! :)
you can use Alamofire 3.0+ below code
func uploadImageAndData(){
//parameters
let gender = "M"
let firstName = "firstName"
let lastName = "lastName"
let dob = "11-Jan-2000"
let aboutme = "aboutme"
let token = "token"
var parameters = [String:AnyObject]()
parameters = ["gender":gender,
"firstName":firstName,
"dob":dob,
"aboutme":about,
"token":token,
"lastName":lastName]
let URL = "http://yourserviceurl/"
let image = UIImage(named: "image.png")
Alamofire.upload(.POST, URL, multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(image, 0.6) {
multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
}, encodingCompletion: {
encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
print("s")
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)")
}
}
case .Failure(let encodingError):
print(encodingError)
}
})
}
SWIFT 2 AlamoFire Simple Image Upload (REST API)
#amit gupta It seems answer contains big overhead. AlamoFire contain load of simplified solution. Alamofire.request method contains several simplified overload which can use to upload in simple manner. By using Alamofire.request( method developer can get rid of encoding overhead.
HTTP Status 415 gives because of not specifying the correct media type.
Please check my solution below.

To use encoding Parameters, make a ParameterEncoding variable, assign it a encoding type (case of the enum which include .JSON, .URL) and then use the encode function with your NSURLRequest and the parameters. This function returns a tuple of two element, the first being the resulting NSURLRequest and the second being the resulting possible NSError.
Here's how I used it for a custom header I needed in a project
var parameterEncoding:ParameterEncoding!
switch method {
case .POST, .PUT :
parameterEncoding = ParameterEncoding.JSON
default :
parameterEncoding = ParameterEncoding.URL
}
var alamoRequest = Alamofire.Manager.sharedInstance.request(parameterEncoding.encode(mutableURLRequest, parameters: parameters).0)
