Bild auf Server mit Alamofire hochladen

Question

Dies ist mein Code, den ich Bild auf Server mit Alamofire hochladen möchte, es ist kein Fehler, aber es kann nicht Bild zum Server schieben. was soll ich machen ? Danke im Voraus.

let url = URL(string: urlString)! 
    var urlRequest = URLRequest(url: url) 
    urlRequest.httpMethod = "POST" 

    let parameters = ["name": rname] 

    do { 
     urlRequest.httpBody = try JSONSerialization.data(withJSONObject: parameters, options: []) 
    } catch { 
     print(error) 
    } 

    urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type") 
     let image = UIImage.init(named: "myImage") 
     let imgData = UIImageJPEGRepresentation(image!, 0.2)! 


    Alamofire.upload(multipartFormData: { MultipartFormData in 

      MultipartFormData.append(imgData, withName: "fileset", fileName: "name", mimeType: "image/jpg") 


     },with: urlRequest,encodingCompletion: { encodingResult in 

      switch encodingResult { 

      case .success(let upload, _, _): 

       upload.responseJSON { response in 

        if let info = response.result.value as? Dictionary<String, AnyObject> { 

         if let links = info["links"] as? Dictionary<String, AnyObject> { 

          if let imgLink = links["image_link"] as? String { 
           print("LINK: \(imgLink)") 
          } 
         } 
        } 

       } case .failure(let error): 
        print(error) 
      } 
     })

Try Code unten

let image = UIImage.init(named: "myImage") 
let imgData = UIImageJPEGRepresentation(image!, 0.2)! 

let parameters = ["name": rname] 

Alamofire.upload(multipartFormData: { multipartFormData in 
     multipartFormData.append(imgData, withName: "fileset",fileName: "file.jpg", mimeType: "image/jpg") 
     for (key, value) in parameters { 
       multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key) 
      } 
    }, 
to:"mysite/upload.php") 
{ (result) in 
    switch result { 
    case .success(let upload, _, _): 

     upload.uploadProgress(closure: { (progress) in 
      print("Upload Progress: \(progress.fractionCompleted)") 
     }) 

     upload.responseJSON { response in 
      print(response.result.value) 
     } 

    case .failure(let encodingError): 
     print(encodingError) 
    } 
}

let params: Parameters = ["name": "abcd" "gender": "Male"] 
Alamofire.upload(multipartFormData: 
    { 
     (multipartFormData) in 
     multipartFormData.append(UIImageJPEGRepresentation(self.yourimageView.image!, 0.1)!, withName: "image", fileName: "file.jpeg", mimeType: "image/jpeg") 
     for (key, value) in params 
     { 
      multipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key) 
     } 
}, to:yourUrl,headers:nil) 
{ (result) in 
    switch result { 
    case .success(let upload,_,_): 
     upload.uploadProgress(closure: { (progress) in 
      //Print progress 
     }) 
     upload.responseJSON 
      { response in 
       //print response.result 
       if response.result.value != nil 
       { 
        let dict :NSDictionary = response.result.value! as! NSDictionary 
        let status = dict.value(forKey: "status")as! String 
        if status=="1" 
        { 
         print("DATA UPLOAD SUCCESSFULLY") 
        } 
       } 
     }     
    case .failure(let encodingError): 
     break 
    } 
}

benötigen name, fileName, mimeType angeben, diese sind wichtig für viele Server

func upload(image: UIImage, completion: (URL?) -> Void) { 
    guard let data = UIImageJPEGRepresentation(image, 0.9) else { 
     return 
    } 

    Alamofire.upload(multipartFormData: { (form) in 
     form.append(data, withName: "file", fileName: "file.jpg", mimeType: "image/jpg") 
    }, to: "https://yourawesomebackend.com", encodingCompletion: { result in 
     switch result { 
     case .success(let upload, _, _): 
     upload.responseString { response in 
      print(response.value) 
     } 
     case .failure(let encodingError): 
     print(encodingError) 
     } 
    }) 
    }
