exports.uploadImage=function(req, res){

let storage = multer.diskStorage({
destination: function(req, file, cb) {
cb(null, './uploads/');
},
filename: function(req, file, cb) {

cb(null, Date.now() + "_" + file.originalname)
}

});
let upload = multer({
storage: storage
}).single('image');
upload(req, res, function(err, result) {

if (err) {
 return res.status(422).send({
 status: false,
 message: "Something got wrong:Invalid Id",
 statusCode: 422,
 data: null
 });
} else {
return res.status(200).send({
 status: true,
