【问题描述】：

我无法使用库 alamofire 将图像文件发送到服务器。我在动态发送图像文件时遇到问题。文件名显示在服务器中，但图像为空白。如何解决？

图片代码

 let parameters = [
                "name": name_txt.text! as String,
                "address": address_txt.text! as String,
                "district": website_txt!.text! as String,
                "country": establishment_txt.text! as String,

            ]

            Alamofire.upload(multipartFormData:  multipartFormData in
                if let imageData = UIImageJPEGRepresentation(self.logo_holder.image!, 1) 
                    multipartFormData.append(imageData, withName: "logo", fileName: "file.png", mimeType: "image/png")
                

                for (key, value) in parameters 
                    multipartFormData.append((value.data(using: .utf8))!, withName: key)
                , to: "http://www.myeducationhunt.com/api/v1/schools", method: .post, headers: ["Authorization": "auth_token"],
                    encodingCompletion:  encodingResult in
                        switch encodingResult 
                        case .success(let upload, _, _):
                            upload.response  [weak self] response in
                                guard self != nil else 
                                    return
                                
                                debugPrint(response)
                            
                        case .failure(let encodingError):
                            print("errorss:\(encodingError)")
                        
            )

我能够接收图像文件名，但图像变成空白。这怎么能 解决了吗？

你可以试试这个

let parameters = [

               "name": name_txt.text! as String,

               "address": address_txt.text! as String,

               "district": website_txt!.text! as String,

               "country": establishment_txt.text! as String



           ]





        Alamofire.upload(multipartFormData:  multipartFormData in

               if let imageData = UIImageJPEGRepresentation(self.logo_holder.image!, 0.5) 

                   multipartFormData.append(imageData, withName: "image", fileName: "image.jpeg", mimeType: "file/jpeg")

                   print("imgdatas",imageData)

               



               for (key, value) in parameters 

                   multipartFormData.append((value.data(using: .utf8))!, withName: key)

               , to: "http://www.myeducationhunt.com/api/v1/schools", method: .post, headers: ["Authorization": "auth_token"],

                   encodingCompletion:  encodingResult in

                       switch encodingResult 

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

                           upload.response  [weak self] response in

                               guard self != nil else 

                                   return

                               

                               debugPrint(response)

                           

                       case .failure(let encodingError):

                           print("errorss:\(encodingError)")

                       

           )
