Regrettably, the solution provided in this answer does not resolve my issue. It seems that the request parameter file is missing from my POST request for some unknown reason.
I am attempting to upload any type of file, be it binary or text, using a POST request. The REST controller implementation looks like this:
@PostMapping(WordEmbeddingApiPaths.UPLOAD_MODEL)
@RequestMapping(method=RequestMethod.POST, headers={"Content-Type=multipart/form-data"})
public ResponseEntity<WordVectorListDto> uploadModel(
@RequestParam("file") MultipartFile file,
RedirectAttributes redirectAttributes) {
LOGGER.debug("POST uploadModel");
return new ResponseEntity<WordVectorListDto>((WordVectorListDto)null, HttpStatus.OK);
}
On the client side, I have the following code running:
var uploader = $scope.uploader = new FileUploader({
url: 'http://localhost:8080/rest-api/dl4j/we/uploadModel'
});
uploader.onAfterAddingFile = function($modelFile) {
console.info('onAfterAddingFile', $modelFile);
var fd = new FormData();
fd.append('file', $modelFile.file);
$http.post($modelFile.url, fd, {
headers: {
'Content-Type': 'multipart/form-data'
},
params: {'file' : $modelFile.file}
})
.then(
function (data) {
alert("upload success");
},
function (data, status) {
alert("upload error");
}
);
};
Despite this, I am receiving a 400 Bad Request response from the server.
Any insights on what might be causing this problem?
Update:
An internal exception was thrown on the server side, indicating:
: Required request part 'file' is not presentorg.springframework.web.multipart.support.MissingServletRequestPartException
It appears that I am already setting this - how can I rectify this situation?
