Hutool的HttpUtil实现调用POST表单接口上传文件

news 2025/11/9 1:04:12

1、客户端代码

private String uploadWithHutool(InputStream inputStream, String channelCode) {if (inputStream == null) {log.error("文件输入流为空，无法上传");return null;}DateTime date = DateUtil.date();String dateTime = DateUtil.formatDateTime(date);String fileName = "漳潭360" + dateTime + ".png";InputStreamResource inputStreamSource;try {inputStreamSource = new InputStreamResource(inputStream, fileName);} catch (Exception e) {log.error("文件输入流转换为InputStreamResource失败", e);return null;}try (HttpResponse response = HttpUtil.createPost(pictureSaveUrl).header("Content-Type", "multipart/form-data")// 设置表单参数（文件），第一个参数为接口接收的参数名（如"file"）.form("file", inputStreamSource)// 可选：添加其他表单参数（如果接口需要）.form("channelCode", channelCode)// 执行请求.execute()) {// 获取响应体（根据接口返回格式调整，如JSON/文本）return response.body();} catch (Exception e) {log.error("截图文件上传失败", e);return null;}}

2、服务端接口代码

    @PostMapping("/add")@ApiOperation("视频截图保存接口")public Result<String> add(@Valid @RequestBody VideoPictureAddPO po) throws IOException {String pictureId = videoDevicePictureService.addVideoPicture(po);return Result.success(pictureId);}

@Data
public class VideoPictureAddPO {/*** 视频通道code，d_video_device*/@NotBlank(message = "视频通道code不能为空")private String channelCode;/*** 截图附件*/@NotNull(message = "截图附件不能为空")private MultipartFile file;}

@Overridepublic String addVideoPicture(VideoPictureAddPO addPO) {log.info("addVideoPicture addPO:{}", addPO);String channelCode = addPO.getChannelCode();MultipartFile file = addPO.getFile();LambdaQueryWrapper<DVideoDeviceDO> lambdaQueryWrapper = Wrappers.lambdaQuery();lambdaQueryWrapper.eq(DVideoDeviceDO::getChannelCode, channelCode);DVideoDeviceDO deviceDO = videoDeviceMapper.selectOne(lambdaQueryWrapper);Assert.notNull(deviceDO, buildBaseException(ARGUMENT_NOT_VALID, "摄像头不存在"));DateTime date = DateUtil.date();String dateTime = DateUtil.formatDateTime(date);String fileName = deviceDO.getStationName() + dateTime + ".png";Tuple tuple = attachmentService.uploadAttachmentWithoutAuthInfo("env-water-ecological", fileName, file);DVideoDevicePictureDO pictureDO = new DVideoDevicePictureDO();pictureDO.setId(IdUtil.getSnowflakeNextIdStr());pictureDO.setEnterpriseCode(deviceDO.getEnterpriseCode());pictureDO.setStationCode(deviceDO.getStationCode());pictureDO.setStationName(deviceDO.getStationName());pictureDO.setChannelCode(deviceDO.getChannelCode());pictureDO.setAttachmentId(tuple.get(0));pictureDO.setAttachmentName(fileName);pictureDO.setDataTime(date);this.save(pictureDO);return pictureDO.getId();}
