now I'm using Alamofire to connecting my iOS app to server with apis.
Our server guy made post request that upload images and some information of this.
And this data send to server with POST method and multipart.
private let files = UIImage(named: "testImg")!.pngData()!
private let payload : [String : [String : String]] = [
"postInfo" : [
"title" : "iOS Test",
"price" : "1000",
"description" : "iOS Test",
"category" : "iOS Test",
"camps" : "[1,2]"
]
]
this is my parameters. And,
func upload() {
AF.upload(multipartFormData: { [weak self] (multipartFormData) in
guard let self = self else { return }
// image
multipartFormData.append(self.files, withName: "files", fileName : "testImg.png", mimeType: "image/png")
// postInfo <- **this part I have in trouble**
for (key, value) in self.payload {
multipartFormData.append("\(value)".data(using: .utf8)!, withName: key, mimeType: "application/json")
}
...
I think nested parameter 'postInfo' does not send well to api.
So how can I send this nested json parameter 'postInfo' with multipart form data?

Guys I need to send parameters described in the image value where content type is multipart/form-data. Im having difficulty in sending only package_json parameter.
The problem is I don't know how do I send multiple package_json values as parameter? I can send one value like this:
let param = [
"outletId : "1",
"vehicleId" : "1",
"instructions" : tvInstructions.text,
"package_json" : "[{\"packageId\":\"1\"}]",
"addressId" : "1"
]
Above i'm able to send package_json = [{"packageId": 1}] as String as my function below sends parameters as [String : String] and images of Data type as [String : Any]. Im having problem sending multiple values in package_json. For eg. something like this: [{"packageId": 1}, {"packageId": 2}, {"packageId": 3}] and so on. Here's the function that i'm using to send parameters:
func postrequest(_ request: String, onPath imagesData:[Data]?,_ imageName : String, andParameter parameters: [String:String]?, withCompletion response: #escaping serviceCompletion) {
let headers: HTTPHeaders
headers = ["Content-type": "multipart/form-data"]
AF.upload(multipartFormData: { multiPart in
if let allParams = parameters {
for (key, value) in allParams {
multiPart.append(value.data(using: .utf8)!, withName: key)
}
}
for imageData in imagesData ?? [] {
multiPart.append(imageData, withName: "\(imageName)", fileName: "file.jpg", mimeType: "image/jpg")
}
}, to: request, usingThreshold: UInt64.init(),
method: .post,
headers: headers).response { (res) in
if((res.error == nil)){
do {
response(res.data,res.error)
}
}
else{
// hideHud()
response(res.data,res.error)
}
}
}
I tried to convert function to send [String: Any] data but found out we can only send as [String : String] along with images as [String : Any].
I just want to know if there is any way to modify "package_json" : "[{\"packageId\":\"1\"}]" so I can send [{"packageId": 1}, {"packageId": 2}, {"packageId": 3}]?
Just in case, this is how im calling above function and sending parameters:
func sendData() {
let param = [
"outletId" : "1",
"vehicleId" : "1",
"instructions" : tvInstructions.text,
"package_json" : "[{\"packageId\":\"1\"}]",
"addressId" : "1"
]
ApiNetworkManager.shared.postrequest(Api.completeUrl, onPath: [], "", andParameter: param) { (response, err) in
ApiNetworkManager.shared.hideHud()
debugPrint(param)
let json = JSON.init(response!)
debugPrint(json)
if err == nil {
if err == nil && response != nil {
if json.dictionaryValue["success"]?.stringValue == "1" {
//Add your code here
}
else{
let message = json.dictionaryValue["message"]?.stringValue
self.showAlert(Message: message ?? "Error")
}
} else {
// hideHud()
print(err?.localizedDescription as Any)
let message = json.dictionaryValue["message"]?.stringValue
self.showAlert(Message: message ?? "Error")
}
}
else{
ApiNetworkManager.shared.hideHud()
let message = err?.localizedDescription
self.showAlert(Message: message ?? "Error")
}
}
}
I have been trying to upload multiple images(3) with parameters using alamofire but i cant seem to do it.(My lack of knowledge). Could someone kindly help me out with this?
This is what i have tried
{
let headers: HTTPHeaders = [
xyz
]
let param : [String: Any] = [
"emp_Id" : "",
"device_Identifier" : "",
"timestamp" : "",
"description" : "",
"handoverStatus" : ""
]
AF.upload(
multipartFormData: { multipartFormData in
multipartFormData.append(imgData0, withName: "media1" , fileName: "file0.jpeg", mimeType: "image/jpeg")
multipartFormData.append(imgData1, withName: "media2",fileName: "file1.jpg", mimeType: "image/jpg")
multipartFormData.append(imgData2, withName: "media3",fileName: "file1.jpg", mimeType: "image/jpg")
// I think im supposed to add the last part here but i dunno how to do that
},
to: "http://ip.here.--.--/new.php", method: .post , headers: headers)
.response { resp in
print(resp)
}
}
This is what the server expects
[{"key":"media1","description":"","type":"file","value":["/C:/Users/x/x/Saved Pictures/x.jpg"]},
[{"key":"media2","description":"","type":"file","value":["/C:/Users/x/x/Saved Pictures/x.jpg"]},
[{"key":"media3","description":"","type":"file","value":["/C:/Users/x/x/x.jpg"]},
{"key":"model","value":"{\"emp_Id\": \"6\",\"device_Identifier\":\"Device 01\",\"timestamp\":\"\123\,
”\description\”:\”description\",”handoverStatus”:”false”}","type":"text"}]
I dunno how to add the last part to the multipart form data, could some point me in the right direction ?
Thanks
Try this method to upload multiple images
class func uploadImageWithURL(endPath : String, dictImage : [String:[UIImage]], parameter : [String : Any], header : HTTPHeaders? = nil, success : #escaping ( Any? )->Void, failure : #escaping (Error) -> Void){
let baseUrl = "your base URL"
let fullUrl = baseUrl + endPath
var headers = ["Content-type" : "multipart/form-data"]
if let header = header{
headers = header
}
let url = (try? URLRequest(url: fullUrl, method: .post, headers: headers))!
upload(multipartFormData: { (multipartData) in
for imagesData in dictImage {
for arrimage in imagesData.value{
multipartData.append(arrimage.jpegData(compressionQuality: 0.50)!, withName: imagesData.key, fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "image/jpeg")
}
}
for (key, value) in parameter {
multipartData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
}, with: url) { (resultData) in
switch resultData{
case .success(let upload, let streamingFromDisk, let fileURL):
print("File URL : \(String(describing: fileURL))")
print("Streaming From Disk : \(streamingFromDisk)")
upload.uploadProgress(closure: { (progress) in
print("Progress : \(progress.fractionCompleted)")
})
upload.responseJSON(queue: nil, options: .allowFragments, completionHandler: { (response) in
if let value = response.result.value
{
success(value)
}
})
case .failure(let error):
failure(error)
print(error)
}
}
}
I'm having difficulty with a parameter which contains a Json array using Alamofire
Here is a string of my Json:
"[{\"id\":546836102,\"count\":1},{\"id\":216479424,\"count\":1}]"
Here is my code where I make the request:
let data = (params["cart"] as! String).data(using: .utf8)!
do {
if let jsonArray = try JSONSerialization.jsonObject(with: data, options : .fragmentsAllowed) as? [Dictionary<String, Int>] {
let parameters: Parameters = [
"address_id": params["address_id"] as! Int,
"delivery_day": params["delivery_day"] as! String,
"delivery_hour": params["delivery_hour"] as! Int,
"cart": jsonArray,
"via": params["via"] as! String
]
Alamofire.request(Global.baseURL + "orders/finish", method: .post, parameters: parameters, encoding: URLEncoding.default, headers: header)
.responseSwiftyJSON {
Printing out my parameters
["cart": [["id": 546836102, "count": 1], ["count": 1, "id": 216479424]], "address_id": 641589205, "delivery_day": "1399-01-20", "delivery_hour": 21, "via": "ios"]
Backend must receive the cart as below:
[
{
"id": 123456,
"count": 2
},
{
"id": 654321,
"count": 3
}
]
But instead it gets the data like this:
{
"delivery_hour" : "21",
"delivery_day" : "1399-01-20",
"cart" : [
{
"count" : "1"
},
{
"id" : "546836102"
},
{
"count" : "1"
},
{
"id" : "216479424"
}
],
"via" : "ios",
"address_id" : "641589205"
}
I have tried JSONEncoding and URLEncoding options by Alamofire but nothing seems to work and this is the closest I've gotten to the API template so far.
What am I doing so wrong here?
// MARK: - Update
So I updated to the latest version of Alamofire and still no good results :(
Here is the code:
let payload = MyParameters(address_id: 641589205, delivery_day: "1399-01-21", delivery_hour: 21, cart: items, via: "ios")
AF.request(url, method: .post, parameters: payload, encoder: JSONParameterEncoder.default, headers: .init(header), interceptor: nil).response { dataResponse in
switch dataResponse.result {
case .success(let value):
if dataResponse.response?.statusCode == 200 {
let json = JSON(value!)
completionHandler(json, nil)
} else {
print(dataResponse.response?.statusCode ?? -1)
}
case .failure(let error):
print(error)
completionHandler(nil, error.localizedDescription)
}
}
My payload looks exactly what I want it to be
{
"cart" : [
{
"count" : 1,
"id" : 546836102
},
{
"count" : 1,
"id" : 216479424
}
],
"via" : "ios",
"address_id" : 641589205,
"delivery_day" : "1399-01-21",
"delivery_hour" : 21
}
But then again the endpoint receives this:
{
"{\"delivery_day\":\"1399-01-21\",\"address_id\":641589205,\"delivery_hour\":21,\"cart\":" : {
"{\"id\":546836102,\"count\":1},{\"id\":216479424,\"count\":1}" : null
}
}
Using Alamofire 4, you can't send arrays using the method you've shown, as the Parameters type is [String: Any]. You're also not using the correct ParameterEncoding. If you want to send a JSON body, you need to use the JSONEncoding. What you can do is manually serialize the array into a URLRequest and make that request using Alamofire.
Additionally, if you update to Alamofire 5, Encodable parameters are now supported, so you if you can define your parameters as an Encodable type, sending them would be as easy as passing an array.
AF.request(..., parameters: [some, encodable, values], encoder: JSONEncoder.default)...
I need to do this in my project:
multiple values in multiple array common key for parameter
Some links that have the same question but no exact answers, I always see posts that have answers like use a custom encoding and that's it.
https://github.com/Alamofire/Alamofire/issues/570
i have 4 array :
var imagesArray: [UIImage] = [], var DayOpreation: [String] = [],varDayOffStart: [String] = [], var DayOffEnd: [String] = []
and this my code :
let parameters : Parameters = [
"about": self.descriptionLabel.text!,
"address" : addressLabel.text!,
"country" : "1",
"state": "1",
"city" : "1",
"postcode" : self.postalCode.text!,
"policies": self.policiesLabel.text,
"longitude" : "",
"latitude" : "",
"available_24hours": "0",
"open_hour" : "09:00",
"closed_hour" : "18:00",
"operating_days[0]": "Senin",
"days_off[0][start]" : "2019-10-10",
"days_off[0][end]" : "2019-10-15",
]
let token = UserDefaults.standard.string(forKey: UserDefaultConstant.ACCESS_TOKEN)
let headers = ["key": "\(token!)"
]
let ImageData = UIImageView()
ImageData.image = UIImage(named: "rectangle-1")
let imgData = UIImagePNGRepresentation(ImageData.image!)!
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(imgData, withName: "photo_profile[0]",fileName: "file.jpg", mimeType: "image/jpg")
for (key, value) in parameters {
multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
},
to:"\(Endpoints.BASE)\(Endpoints.UPDATE_VENDOR)",
method: .post,
headers: headers,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
if let data = response.data {
guard let json = try? JSON(data: data) else { return }
let messageRoom = json["message"].string
print("listOfficialRoom== ",json)
}
}
case .failure(let encodingError):
print(encodingError)
}
})
Use Paramaters in Alamofire, something like this
let daysOff = [String: Any]() // array of dictionaries for days off
for (i, day) in days.enumerated() {
let dayOff: Parameters = [
"start": day.start,
"end": day.end
]
daysOff["\(i)"] = dayOff
}
let parameters: Parameters = [
"open_hour": "...",
"closed_hour": "...",
"days_off": daysOff
]
upload(.POST, isEdit == true ? mainURL+URLS.UpdateLicense.rawValue : mainURL+URLS.AddLicense.rawValue, multipartFormData: {
multipartFormData in
if let imageData = UIImageJPEGRepresentation(self.selectdImage, 1) {
multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "image.jpeg", mimeType: "image/jpeg")
I want to append body part in the string and I can't find any method by that I can append a string with this body part. It's required only data.But my parameter is a string and I have to pass it as a string not in data.
Try this:
Swift 2.0
multipartFormData.appendBodyPart(data: imageData.dataUsingEncoding(NSUTF8StringEncoding)!, name: "image")
Swift 3.0
multipartFormData.append(imageData(using: String.Encoding.utf8)!, withName: "image")
This is my code in my project. I Hope it can help you
var parameters: [String: String] = [
"Tag" : tagName,
"Title" : title,
"Content" : content,
"TypePost" : "0",
"CreatedAt" : "\(Date())"
]
for (key, value) in parameters {
multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
}
You want to upload UIImage with other parameters, so here how you can achieve that!
if let imageData = UIImageJPEGRepresentation(image, 1) {
multipartFormData.appendBodyPart(data: imageData, name: "file", fileName: "file.png", mimeType: "image/png")
}
for (key, value) in parameters {
multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
}
You need to differentiate both the things UIImage and other String parameters.
Let me know, if you still face problem.
