Upload images to the server using Alamofire - swift

Question

The following problem arose, the fact is that sometimes images are not uploaded to the server. All the data is correct, the image is present, the variables are arranged in the correct order, the function reports a successful upload, but sometimes the images still do not reach the server. There are no such problems with the Retorfit library, but with Alamofire it often arises. I can not figure out yet why.
class func write_photo(params:[String:String],image:UIImage, in_position:String, completion:_ js:String, _ success:Bool -> Void, failure:_ errorMessage:String,_ failure:Bool -> Void) {
let url = BaseURL + "xdb_items.write_photo"
let URL = try! URLRequest(url: url, method: .post)
let in_idclient = params["in_idclient"]
let in_iditem = params["in_iditem"]
let imgData = UIImageJPEGRepresentation(image, 0.5)!
sessionManagerImage.upload(multipartFormData: { multipartFormData in
multipartFormData.append((in_idclient?.data(using: String.Encoding.utf8)!)!, withName: "in_idclient")
multipartFormData.append((in_iditem?.data(using: String.Encoding.utf8)!)!, withName: "in_iditem")
multipartFormData.append(imgData, withName: "in_filename", fileName: "photo", mimeType: "image/png")
multipartFormData.append((in_position.data(using: String.Encoding.utf8)!), withName: "in_position")
}, with: URL, encodingCompletion: {
encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.response { response in
completion("", true)
}
case .failure(let encodingError):
print("ERROR RESPONSE: \(encodingError)")
}
})
}
my friends, when I did the application rollout, the Xcode issued such a warning on the id_item variable: could not execute support code to read Objective-C class data in the process. at real iPhone device maybe this is the problem
found an error, status code 500, because of what it can occur?
Postman work great! Screenshot Postman:

Code that Postman offers, but I need Alamofire:
import Foundation
let headers = [
"content-type": "multipart/form-data; boundary=----WeXXXXXXXXXXXXXXXXXXrZu0gW",
"Authorization": "Basic dXXXXXXXXXXXX=",
"cache-control": "no-cache",
"Postman-Token": "2c1bXXXXXXXXXXXXXXXXX4e"
]
let parameters = [
[
"name": "in_filename",
"fileName": "/home/iv/Рабочий стол/Скрины/Скрин6.png"
],
[
"name": "in_idclient",
"value": "516"
],
[
"name": "in_iditem",
"value": "1232"
],
[
"name": "in_position",
"value": "5"
]
]
let boundary = "----WeXXXXXXXXXXXXXXXXXXrZu0gW"
var body = ""
var error: NSError? = nil
for param in parameters {
let paramName = param["name"]!
body += "--\(boundary)\r\n"
body += "Content-Disposition:form-data; name=\"\(paramName)\""
if let filename = param["fileName"] {
let contentType = param["content-type"]!
let fileContent = String(contentsOfFile: filename, encoding: String.Encoding.utf8)
if (error != nil) {
print(error)
}
body += "; filename=\"\(filename)\"\r\n"
body += "Content-Type: \(contentType)\r\n\r\n"
body += fileContent
} else if let paramValue = param["value"] {
body += "\r\n\r\n\(paramValue)"
}
}
let request = NSMutableURLRequest(url: NSURL(string: "http://XXXXXXXXXX:XXXX/XX/xdb_items.write_photo")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
}
})
dataTask.resume()

Answer 1

try instead of this
multipartFormData.append(imgData, withName: "in_filename", fileName: "photo", mimeType: "image/png")
to
multipartFormData.append(imgData, withName: "profile_photo")
may be this will helpful for you

Answer 2

let imageData : Data! = (UIImage converted to Data)
Alamofire.upload(multipartFormData: { (multipartFormData) in
multipartFormData.append(imageData, withName: "image", fileName: "file.jpeg", mimeType: "image/jpeg")
}, to: NSURL(string: "http://URL you want to upload it to")! as URL)
{ (result) in
switch result {
case .success(let upload, _, _):
//Success
case .failure(let encodingError):
//Failure
}
}
