                      Is there a change to return a png file like response.png instead of response.bin

                      Asked 2020-Oct-02 at 14:32

                      The aim of my code is to retrieve an image from a third-party service.

                      I struggled a little for endpoint of download to work and only partially succeeded. When I call the endpoint via postman the answer is a .bin file, but what I need is to have a .png file. The greatest success is being able to get a .png file being able to customize the name as well. But personalization of the is not strictly necessary.

                      The project is built with the initializer and has the following dependencies:

                      • spring-boot-starter-web;
                      • lombok
                      • spring-boot-starter-webflux
                      • reactor-spring

                      Below is the source code of my endpoint:

                      @GetMapping("/retrieve-image")
                      public Mono<byte[]> retrieveImage(ImageRequest request) throws ExecutionException, InterruptedException, IOException {
                          MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();
                          queryParams.add("attribute", request.getAttribute()); // fake for query string setting.
                          Mono<byte[]> image = webClient
                                  .get()
                                  .uri(uriBuilder -> uriBuilder
                                          .path(Endpoint.THIRD_PARTY_SERVICE_URI)
                                          .queryParams(queryParams)
                                          .build())
                                  .accept(MediaType.valueOf(String.valueOf(MediaType.IMAGE_PNG)))
                                  .exchange()
                                  .flatMap(clientResponse -> clientResponse.bodyToMono(byte[].class)
                                          .doOnSuccess(body -> {
                                              if (clientResponse.statusCode().isError()) {
                                                  log.error("HttpStatusCode = {}", clientResponse.statusCode());
                                                  log.error("HttpHeaders = {}", clientResponse.headers().asHttpHeaders());
                                                  log.error("ResponseBody = {}", body);
                                              }
                                          }));
                          return image;
                      }

                      You can also add the mime type of the file to the produces section of the @GetMapping annotation, it should look something like this:

                      @GetMapping(path = "/retrieve-image",
                              produces = "image/png")
                      

                      Additionally, instead of returning a Mono<byte[]>, you can wrap your response in a ResponseEntity<Resource>. This gives you the possibility to add Headers and tell the browser the name of your file. For example:

                      HttpHeaders header = new HttpHeaders();
                      header.add(HttpHeaders.CONTENT_DISPOSITION,
                              "attachment; filename=image.png");
                      header.add("Access-Control-Expose-Headers", "Content-Disposition");
                      
                      return ResponseEntity.ok().
                              .headers(header)
                              .contentLength(Files.size(path))
                              .body(<<YOUR_FILE_HERE>>);
                      

                      One last thought: If you add both spring-boot-starter-web and spring-boot-starter-webflux to your dependencies, the app will work, but it doesn't use Netty from Webflux, instead the usual Tomcat. So you don't benefit from the reactive features.
