从我得到的错误发生在 ServerUtils.internalPostRequest(ServerUtils.java:77) 和 ServerUtils.saveFile(ServerUtils.java:266) 因为 MediaPlayerCtrl.save(MediaPlayerCtrl.java:117) 只是调用 saveFile( ） 方法。我认为这会导致服务器上的 FileController，但我不知道是什么导致了错误。我将在下面保留我之前引用的方法。
private <T> T internalPostRequest(String path, Entity send, GenericType<T> retType) {
return ClientBuilder.newClient(new ClientConfig())
.target(getServer()).path(path)
.request(APPLICATION_JSON)
.accept(APPLICATION_JSON)
.post(send, retType);
}
public void saveFile(File file){
internalPostRequest("secure/" + store.accessStore().getUsername() + "/file/add",
Entity.entity(file, APPLICATION_JSON), new GenericType<>(){});
}
@SpringBootApplication
@RestController
@RequestMapping(value = {"/secure/{username}/{password}/file", "/secure/{username}/file"})
public class FileController {
@Autowired
private StorageService service;
@PostMapping("/add")
public ResponseEntity<?> uploadFile(@RequestParam("file") MultipartFile file) throws IOException {
String uploadFile = service.uploadFile(file);
return ResponseEntity.status(HttpStatus.OK)
.body(uploadFile);
}
@Service
public class StorageService {
@Autowired
private StorageRepository repository;
public String uploadFile(MultipartFile file) throws IOException {
FileData fileData = repository.save(new FileData(file.getOriginalFilename(),
file.getContentType(), compressFile(file.getBytes())));
return "File uploaded succesfully: "+ file.getOriginalFilename();
}
public static byte[] compressFile(byte[] data) {
Deflater deflater = new Deflater();
deflater.setLevel(Deflater.BEST_COMPRESSION);
deflater.setInput(data);
deflater.finish();
ByteArrayOutputStream outputStream = new ByteArrayOutputStream(data.length);
byte[] tmp = new byte[4*1024];
while (!deflater.finished()) {
int size = deflater.deflate(tmp);
outputStream.write(tmp, 0, size);
}
try {
outputStream.close();
} catch (Exception ignored) {
}
return outputStream.toByteArray();
}
public String getType(String fileName){
Optional<FileData> dbFileData = repository.findByName(fileName);
if (dbFileData.isPresent()) {
return dbFileData.get().getType();
} else {
return "File not found: " + fileName;
}
}
我试着尽可能深入地钻进兔子洞，但我并没有真正注意到任何问题。对于上下文：这应该处理媒体文件——照片（jpg、png）和视频（mp3、mp4、wav 等）
