  //MultipartFile类型转换成File
        File file = null;
        try { 
   
            String originalFilename = image_data.getOriginalFilename();
            String[] filename = originalFilename.split("\\.");
            file=File.createTempFile(filename[0], filename[1]);
            image_data.transferTo(file);
            file.deleteOnExit();
        } catch (IOException e) { 
   
            e.printStackTrace();
        }
        //图片鉴黄
        String s = checkImgUrl(file);
        JSONObject jsonObject = JSONObject.parseObject(s);
        String errcode = jsonObject.get("errcode").toString();
        if(errcode == "" || !errcode.equals("0")){ 
   
            return resultMap(Type.error, "图片不合格!", "", null, "", "501");
        }

  String url = "https://api.weixin.qq.com/wxa/img_sec_check?access_token=" +getAccessToken();
        RequestBody builder = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("media",file.getName(), RequestBody.create(file, MediaType.parse("*/*")))
                .build();
        Request request = new Request.Builder()
                .url(url)
                .post(builder)
                .build();

        try (Response response = client.newCall(request).execute()) { 
   
            return Objects.requireNonNull(response.body()).string();
        } catch (Exception e) { 
   
            e.printStackTrace();
        }
        return "";
