Demande multipart avec ios10

Question

Je travaille sur une requête multipart avec swift, iOS10.

L'image enregistrée sur le serveur avec le code ci-dessous. Et juste recevoir l'erreur 404 lorsque vous ouvrez l'image avec l'URL.

Je ne peux pas trouver ce qui ne va pas dans mon code bien renvoyé à la page Web - https://newfivefour.com/swift-form-data-multipart-upload-URLRequest.html

S'il vous plaît aider.

func connectToServerWithImage(urlString: String, param: Any, image: UIImage, target: NSObject, action: Selector) { 

    let url = URL(string: urlString)! 
    var request = URLRequest(url: url) 

    // set request configuration 
    let boundary = "Boundary-\(UUID().uuidString)" 
    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type") 
    request.httpMethod = "POST" 

    // set body 
    let body = NSMutableData() 
    let paramDic = param as! Dictionary<String, String> 

    // set param to body 
    for (key, value) in paramDic { 
     body.append("--\(boundary)\r\n".data(using: .utf8, allowLossyConversion: false)!) 
     body.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n".data(using: .utf8)!) 
     body.append("\(value)\r\n".data(using: .utf8)!) 
    } 

    // set image to body 
    let filename = paramDic["\(paramDic["TYPE"]!)_MST_NO"]! + ".jpg" 
    body.append("--\(boundary)\r\n".data(using: .utf8, allowLossyConversion: false)!) 
    body.append("Content-Disposition: form-data; name=\"file\"; filename=\"\(filename)\"\r\n\r\n".data(using: .utf8, allowLossyConversion: false)!) 
    body.append("Content-Type: image/jpg\r\n\r\n".data(using: .utf8, allowLossyConversion: false)!) 
    body.append(UIImageJPEGRepresentation(image, 1)!) 
    body.append("\r\n".data(using: .utf8, allowLossyConversion: false)!) 
    body.append("--\(boundary)--\r\n".data(using: .utf8, allowLossyConversion: false)!) 

    request.httpBody = body as Data 

    // url configuration 
    let urlConfig = URLSessionConfiguration.ephemeral 
    urlConfig.timeoutIntervalForRequest = 5 
    urlConfig.timeoutIntervalForResource = 5 

    let session = URLSession(configuration: urlConfig) 

    let dataTask = session.dataTask(with: request) { (data, response, error) in 
     session.finishTasksAndInvalidate() 
     DispatchQueue.main.async { 
      if error == nil { 

       if let httpUrlResponse = response as? HTTPURLResponse { 
        if httpUrlResponse.statusCode == 200 { 
         do { 
          let jsonObject: Dictionary<String, Any> = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers) as! Dictionary<String, Any> 

          if jsonObject.isEmpty { 
           target.perform(action, with: ["RES_CODE:": "NULL"]) 
          } 
         } catch let _ {} 
        } 
       } 
      } 
     } 
    } 
    dataTask.resume() 
}

Exemple de code pour l'API dans iOS 10 Multipart:

func Api_MultiPart() 
{  
    var url_request = URLRequest(url: URL(string: EmployerRegApi())!) 
    url_request.httpShouldHandleCookies = false 
    url_request.timeoutInterval = 60 
    url_request.httpMethod = "POST" 

    let boundary = "-----------Sample------------" 
    let form_data = "multipart/form-data; boundary=\(boundary)" 
    url_request.setValue(form_data, forHTTPHeaderField: "Content-Type") 

    let body = NSMutableData() 

    /*----------------- Company -----------------*/ 
    body.appendString("--\(boundary)\r\n") 
    body.appendString("Content-Disposition: form-data; name=\"\(str_company_name_key)\r\n\r\n") 
    body.appendString("\(str_company_name_val)\r\n") 

    /*--------------- Address ID ---------------*/ 
    body.appendString("--\(boundary)\r\n") 
    body.appendString("Content-Disposition: form-data; name=\"\(str_address2_key)\r\n\r\n") 
    body.appendString("\(str_address_val)\r\n") 

    /*--------------- State Code ---------------*/ 
    body.appendString("--\(boundary)\r\n") 
    body.appendString("Content-Disposition: form-data; name=\"\(str_country_key)\r\n\r\n") 
    body.appendString("\(str_country_val)\r\n") 

    /*------------- Profile Image --------------*/ 
    if (str_photo_val != nil) 
    { 
     body.appendString("--\(boundary)\r\n") 
     let mimetype = "image/jpg" 
     let defFileName = generate_Image_Name_Multipart() //yourImageName.jpg 
     let imageData = UIImageJPEGRepresentation(str_photo_val!, 1) 

     body.appendString("Content-Disposition: form-data; name=\"\(str_photo_key)\"; filename=\"\(defFileName)\"\r\n") 
     body.appendString("Content-Type: \(mimetype)\r\n\r\n") 
     body.append(imageData!) 
     body.appendString("\r\n") 
    } 
    body.appendString("--\(boundary)\r\n") 

    url_request.httpBody = body as Data 
    let postLength: String = "\(UInt(body.length))" 
    url_request.setValue(postLength, forHTTPHeaderField: "Content-Length") 

    let task = URLSession.shared.dataTask(with: url_request, completionHandler: { (data, response, error) in 
     if error != nil{ 
      print("Error -> \(String(describing: error))") 
      DispatchQueue.main.async { 
       hideLoadingHUD(for_view: self.view) 
      } 
      return 
     } 
     do { 
      let result = try JSONSerialization.jsonObject(with: data!, options: []) as? [String:AnyObject] 
      print("Result -> \(String(describing: result))") 
      DispatchQueue.main.async { 
       hideLoadingHUD(for_view: self.view) 
      } 

     } catch { 
      print("Error -> \(error)") 
      DispatchQueue.main.async { 
       hideLoadingHUD(for_view: self.view) 
      } 
     } 
    }) 
    task.resume() 
} 


func generate_Image_Name_Multipart() -> String { 
    let min: Int = 1 
    let max: Int = 999 
    let randNum: Int = (Int(arc4random_uniform(3)) % Int((max - min) + min)) 
    print("Random Number: \(randNum)") 
    let dateformate = DateFormatter() 
    dateformate.dateFormat = "ddMMyyyyHHmmss"
