在almofire swift上传图片multipart

Question

我有以下数据格式上传图片。我在编码字符串数组时遇到问题，而且我还有字典中的bool数据。

发布词典

[“title”：title，“desription”：description，“privacy”：public，“status”：true，“ids”：[“1”，“2”，“3”]]

我的编码：

    Alamofire.upload(multipartFormData: { multipartFormData in

        if let imageData = UIImageJPEGRepresentation(multiPartParams?["image"] as! UIImage , 0.5) {
            multipartFormData.append(imageData, withName: multiPartParams?["parameter"] as! String, fileName: "image.jpg", mimeType:  "image/jpeg")
        }
        if params != nil {
            for (key, value) in params! {
                multipartFormData.append(((value  as AnyObject).data(using: String.Encoding.utf8.rawValue))!, withName: key)
            }}}, to: url, method: .post, headers: DataHandler.sharedInstance.getHeader(contentType: false),
            encodingCompletion: { encodingResult in

                switch encodingResult {

                case .success(let upload, _, _):
                    upload.responseJSON { response in

                        guard response.result.error == nil else { // error for eg : network unavailable
                            completion(nil, response.result.error as NSError?)
                            return;
                        }

                        let reponseObject = response.result.value as? [String:AnyObject?]

                        guard reponseObject != nil else { // reponse is nil
                            let error = NSError(domain: "No Data",
                                                code: 404,
                                                userInfo: [NSLocalizedDescriptionKey : "No Data Returned"])
                            completion(nil, error)

                            return;
                        }


                        if (reponseObject![ResponseKey.success.rawValue] as? [String : AnyObject]) != nil { // Successfully get response
                            debugPrint( reponseObject)

                            completion(reponseObject![ResponseKey.success.rawValue]??[ResponseKey.data.rawValue]! as AnyObject?, nil)

                        } else if (reponseObject![ResponseKey.error.rawValue] as? [String : AnyObject]) != nil { //server  error

                            let responseData = Mapper<Response>().map(JSON: reponseObject![ResponseKey.error.rawValue]  as! [String : AnyObject])

                            let error = NSError(domain: "",
                                                code: (responseData?.code)!,
                                                userInfo: [NSLocalizedDescriptionKey : (responseData?.message?[0])! as String])

                            completion(nil, error)

                        }
                    }
                case .failure(let encodingError):
                    completion(nil, encodingError as NSError?)

                    print("error:\(encodingError)")
                }
    })
