I can not upload the file to the server

I can’t upload a file to the server via a form, using AngularJS and RESTFul NodeJS, as well as widgets from kendo Code on Angular:

saveBook: function (data, method) { var url = ""; if (method.toUpperCase() === 'PUT') { url = constantService.SERVER_URL + 'books/' + data._id; } else { url = constantService.SERVER_URL + 'books'; } return $http({ method: method, url: url, data: data, headers: {'Content-Type': 'application/json'} }); } 

Code on NodeJS:

 var express = require('express'), router = express.Router(), Category = require('../models/Category'), multer = require('multer'), upload = multer({dest: './uploads/'}).any(), Book = require('../models/Book'); .post(function (req, res) { upload(req, res, function (err) { if (err) { console.log(err); return; } console.log(req.file); console.log(req.files); console.log(req.body.title); console.log(JSON.stringify(req.headers)); }); 

});

console.log(req.file) and console.log(req.files) display undefined

enctype="multipart/form-data" - the form has

BookController controller:

 $scope.save = function () { bookService.saveBook($scope.model, method).success(function (data, status) { $scope.booksWindow.close(); errorService.processError(data.message, status); $scope.refreshBooksTable(); }).error(function (data, status) { errorService.processError(data.errmsg, status); }) } <div class="row"> <div class="col-md-6"> <div class="form-group"> <label for="img">Выберите обложку</label> <input id="img" type="file" kendo-upload="img" name="img" class="form-control" ng-model="model.img" style="width: 100%"/> </div> </div> </div>
