Swift form-data using Alamofire 5 with parameters - swift

Question

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:

Answer 1

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 {
}
}
