春云假装不上传视频文件

Question

    @Override
    public Response<String> uploadFile(final Object object, final MultipartFile multipartFile) {
        final Map<String, Object> s3Url = videoServiceFeign.uploadFile(multipartFile,
                object.getId().toString(), object.getIdIds().toString(), object.getName());
        object.setS3Url(s3Url.get("object").toString());
        return generateSuccessResponse();
    }

    @Override
    public Response<String> uploadFile(final Stream stream, final File file) throws IOException {
        final InputStream inputStream = Files.newInputStream(file.toPath());
        final MultipartFile multipartFile = new MockMultipartFile(file.getName(), file.getName(),
                ContentType.MULTIPART_FORM_DATA.toString(), IOUtils.toByteArray(inputStream));
        return this.uploadFile(stream, multipartFile);
    }

@FeignClient(name = "video-service", url = "${video-service.ribbon.listOfServers}")
public interface VideoServiceFeign {

    @PostMapping(path = "/api/v1/video/upload", consumes = {"multipart/form-data"})
    Map<String, Object> uploadFile(@RequestPart("file") MultipartFile multipartFile,
                                   @RequestParam("id") String id,
                                   @RequestParam("ids") String ids,
                                   @RequestParam("name") String name);

}

    @ApiOperation("Upload new video file")
    @ApiResponses({
            @ApiResponse(code = 200, message = "File uploaded successfully"),
            @ApiResponse(code = 403, message = "Access Denied"),

    }

Answer 1

经过几天的研究，我发现了我所忽略的问题，即该方法的问题:public response uploadFile（final Stream Stream，final File File）抛出IOException

在行中：

final MultipartFile multipartFile = new MockMultipartFile(file.getName(), file.getName(), ContentType.MULTIPART_FORM_DATA.toString(), IOUtils.toByteArray(inputStream));

我有两个问题，首先是内容类型，我使用video/mp4而不是contenttype.multipart_form_data。第二个参数是mockmultipartfile构造函数中的第一个参数。我使用file.getname()，但这是不正确的，因为文档说这是多部分请求中的一个字段名。那应该是“文件”。
