How to pass $scope variable data into node.js backend server file? - angularjs

Question

I have json data in $scope variable and i want to use that $scope variable inside my backend app.js node file.
This is my backend file app.js:
app.post('/upload', upload.single('file'), function(req, res) {
var XLSX = require('xlsx');
var workbook = XLSX.readFile('./uploads/' + req.file.filename);
var sheet_name_list = workbook.SheetNames;
var data = XLSX.utils.sheet_to_json(workbook.Sheets[sheet_name_list[0]]);
//var values = [];
console.log(data);
return res.status(200).send(data);
});
app.post('/api/uploadlast',api.addNewContact, function(req,res){
Contact.bulkCreate(excels).then(function(users) {
return res.status(200).send(users);
}).catch(Sequelize.ValidationError, function(err) {
return res.status(422).send(err.errors[0].message);
}).catch(function(err) {
return res.status(400).send(err.message);
});
})
This is my controller file:
$scope.uploadFile = function() {
var file = $scope.myFile;
var uploadUrl = "/upload";
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {
'Content-Type': undefined
}
})
.then(function(response) {
//$state.reload();
$scope.excels = response.data;
console.log("success!!");
})
.catch(function() {
console.log("error!!");
});
}
$scope.uploadLast = function() {
$http.post('/api/uploadlast').then(function(response) {
$state.reload();
});
}
})
I want to get $scope.excels data into my backend to bulkcreate into databases.

You can pass any data with a post request as the second parameter of $http.post(). So you can do something like:
$scope.uploadLast = function() {
var data = {
excels: $scope.excels
};
$http.post('/api/uploadlast', data).then(function(response) {
$state.reload();
});
}
And in your backend, you can access it like:
app.post('/api/uploadlast',api.addNewContact, function(req, res){
var data = req.body.excels;
Contact.bulkCreate(data).then(function(users) {
return res.status(200).send(users);
}).catch(Sequelize.ValidationError, function(err) {
return res.status(422).send(err.errors[0].message);
}).catch(function(err) {
return res.status(400).send(err.message);
});
});
