当我想要上传图片时，出现了错误Required request part 'file' is not present。 我想上传视频和图片。 视频上传正常工作，但图片无法上传。
以下是我的代码：
Spring-boot
@ApiOperation(value = "Post new file")
@RequestMapping(value = "/", method = RequestMethod.POST)
public String handleFileUpload(@RequestParam("file") MultipartFile file,
@RequestParam (value = "accesstoken", required = true) String accessToken,
RedirectAttributes redirectAttributes) throws Exception{
tokenService.verifyAdmin(accessToken);
storageService.store(file);
return "You successfully uploaded " + file.getOriginalFilename() + "!";
}
StorageService.store
@Override
public void store(MultipartFile file) {
try {
if (file.isEmpty()) {
throw new StorageException("Failed to store empty file " + file.getOriginalFilename());
}
Files.copy(file.getInputStream(), this.rootLocation.resolve(file.getOriginalFilename()));
} catch (IOException e) {
throw new StorageException("Failed to store file " + file.getOriginalFilename(), e);
}
}

<div class="controls">
<button class="btn-primary" name="file" ngf-pattern="'image/*'" ngf-accept="'image/*'" ngf-max-size="2MB" ngf-select="ctrl.uploadCoverImageFile($file)">Upload</button>
