alamofire 使用 json 参数上传图片

Question

我是swift的新手我想上传 images（从 1 到 4 - 取决于用户）和 video 文件（如果用户愿意）到我的服务器并发送上传时的其他参数（如文本等）在 android 中，我正在使用改造，这允许我使用 @partmap 来上传我嵌套的 Json 对象。现在 iOS 我正在使用 Alamofire 但我不能找到使用 multipart 发送 json 的功能我该怎么做？我不想要 base 64 图片我已经试过了我的文本内容是嵌套的明明我要在上传数据时发送json参数例如：

image 1 = image
post->content = "some text"

正如我在评论中提到的，您需要一个多部分请求。

// Image file which you want to upload.
guard let image = UIImage(named: "YourImage") else { return }


                let imgRep : NSBitmapImageRep = image.representations.first as! NSBitmapImageRep

                let imgData : Data = imgRep.representation(using: .PNG, properties: [:])!


                let cameraFileName    = "some_random_name_img.png"

                let fileUrl = URL(fileURLWithPath: cameraFileName, isDirectory: true)
                do {

                    try imgData.write(to: fileUrl, options: NSData.WritingOptions.atomic)

                    DispatchQueue.main.async {
                        // Stop Camera Session if you are capturing image from camera
                        self.cameraSession.stopRunning()

                        let someParam   = ""
                        let someParam2  = ""


                        let date = Date()
                        let dateString = "\(date)"



                        Alamofire.upload(multipartFormData: { (multipartFormData) in

                        // Add parameters in request 

         multipartFormData.append(cameraFileName.data(using: .utf8)!, withName: "name")

         multipartFormData.append(dateString.data(using: .utf8)!, withName: "startDatetime")

         multipartFormData.append(someParam.data(using: .utf8)!, withName: "userId")

         multipartFormData.append(someParam2.data(using: .utf8)!, withName: "phoneServiceId")

         multipartFormData.append(fileUrl, withName: "file")

                        }, to:"Your_Api_Url.com") // POST Url
                        { (result) in
                            switch result {
                            case .success(let upload, _ , _):

                                upload.uploadProgress(closure: { (progress) in

                                    print("uploding")
                                })

                                upload.responseJSON { response in
                                    print(response)
                                    print("done")






                                }

                            case .failure(let encodingError):
                                print("failed")
                                print(encodingError)

                            }
                        }

                    }

                }
                catch let error as NSError {
                    print("Ooops! Something went wrong: \(error)")
                }
