I am calling createUserData api.i want response in resonse_data variable but i am getting
undefined value after console in resonse_data variable
async createUserData(req, res) {
var resonse_data = await verifyOtp(req.body);
console.log(resonse_data); // undefined
}
function verifyOtp(data) {
var mobile = data.mobile_no;
var otpval = data.otp_val;
models.mi_otp_details.findOne({
where: {
mi_mobile_no: mobile,
mi_otp_value:otpval
}
}).then(function (otpdetails) {
if (otpdetails.mi_otp_used_status == '1')
{
var response = ['400', 'OTP Used'];
return response;
}
}).catch(function (err) {
var response = ['400', 'OTP or Mobile No Invalid'];
return response;
});
}
Try this code
async createUserData(req, res) {
var resonse_data = await verifyOtp(req.body);
console.log(resonse_data); // undefined
}
function verifyOtp(data) {
var mobile = data.mobile_no;
var otpval = data.otp_val;
return models.mi_otp_details.findOne({ // <----- HERE!!!
where: {
mi_mobile_no: mobile,
mi_otp_value:otpval
}
}).then(function (otpdetails) {
if (otpdetails.mi_otp_used_status == '1')
{
var response = ['400', 'OTP Used'];
return response;
}
}).catch(function (err) {
var response = ['400', 'OTP or Mobile No Invalid'];
return response;
});
}

I want to catch the error from "revokeToken" function and return it as json response in the api.post . But I'm not getting how this to be done. Can anyone help me out with this? Is there any better way of wring it?
app.post('/api/logout', (req, res)=>{
var request = new Request(req);
var response = new Response(res);
var tokenArray = request.headers.authorization.split(" ");
var token = tokenArray[1];
var tokenObj = {
accessToken : token
}
let errmsg = '';
revokeToken(tokenObj, (obj)=>{
errmsg = obj;
});
res.json({
data: null,
result:{
isError: false,
status: 200,
errorMsg: errmsg
}
});
});
var revokeToken = function(token, callback) {
tokenModel.deleteOne({
accessToken: token.accessToken
}).exec((function(callback, err, results) {
var deleteSuccess = results && results.deletedCount === 1;
let result = '';
if (!deleteSuccess) {
return err;
}
else{
return err;
}
}).bind(null, callback));
callback("Token Deleted!")
};
You should be able to retrieve the error object by passing the msg property as parameter to the callback function.
Also, rename the exec function callback to something other than callback:
var revokeToken = function (token, callback) {
tokenModel
.deleteOne({
accessToken: token.accessToken,
})
.exec(
function (done, err, results) {
var deleteSuccess = results && results.deletedCount === 1;
let result = '';
if (!deleteSuccess) {
callback(err.msg);
return;
}
callback('Token Deleted!');
}.bind(null, callback)
);
};
I'm new to Node.js and I'm creating a simple pagination page. The REST API works fine, but consuming it has left me in limbo.
Here is the REST API (other parts have been taken out for brevity)
const data = req.query.pageNo;
const pageNo =
(typeof data === 'undefined' || data < 1) ? 1 : parseInt(req.query.pageNo);
let query = {};
const total = 10;
query.skip = (total * pageNo) - total;
query.limit = total;
try {
const totalCount = await Users.countDocuments();
const pageTotal = Math.ceil(totalCount / total);
const users = await Users.find({}, {}, query);
return res.status(200).json(users);
} catch (error) {
console.log('Error ', error);
return res.status(400).send(error)
};
};
When I return the json with just the 'users' object, like so return res.status(200).json(users); the page renders correctly, but when I pass in other objects like what I have in the code, it fails. This is how I'm consuming the API:
const renderHomepage = (req, res, responseBody) => {
let message = null;
if (!(responseBody instanceof Array)) {
message = 'API lookup error';
responseBody = [];
} else {
if (!responseBody.length) {
message = 'No users found nearby';
}
}
res.render('users-list', {
title: 'Home Page',
users: responseBody,
message: message
});
}
const homelist = (req, res) => {
const path = '/api/users';
const requestOptions = {
url: `${apiOptions.server}${path}`,
method: 'GET',
json: true,
};
request(
requestOptions,
(err, {statusCode}, body) => {
if (err) {
console.log('Ther was an error ', err);
} else if (statusCode === 200 && body.length) {
renderHomepage(req, res, body);
} else if (statusCode !== 200 && !body.length) {
console.log('error ',statusCode);
}
}
);
}
I've searched extensively on both here and other resources but none of the solutions quite answers my question. I hope someone could be of help
I managed to get the access_token via the oauth2 API,
But then when I try to retrieve access to the events I get the following error:
statusCode: 400, code: "BadRequest", message: "Current authenticated context is not valid for thi…OAuth 2.0 implicit flow for single-page web apps."
I've created a Vue Component and this is the function that returns the token :
getToken: function() {
var self = this;
var params = new URLSearchParams();
params.append('client_id', self.client_id);
params.append('client_secret', self.client_secret);
params.append('grant_type', self.tokenSettings.grant_type);
params.append('resource', self.tokenSettings.resource);
var url = self.tokenSettings.url;
axios.post(url,
params, {
withCredentials: false
})
.then(function(response) {
self.access_token = response.data.access_token;
self.token_type = response.data.token_type;
self.expires_in = response.data.expires_in * 1000;
self.isAuthenticated = true;
self.getEvents();
window.setInterval(function() {
self.getToken();
}.bind(self), response.data.expires_in * 1000);
})
.catch(function(error) {
self.isAuthenticated = false;
});
}
And below is the function I am tryig to get the events with but the returns the error above:
getEvents: function() {
var self = this;
var apiUrl = '/me/events';
if (self.access_token) {
// Create a Graph client
var client = MicrosoftGraph.Client.init({
authProvider: (done) => {
// Just return the token
done(null, self.access_token);
}
});
client
.api(apiUrl)
.select('*')
.orderby('createdDateTime DESC')
.get((err, res) => {
console.log('res', res);
if (err) {
console.log('error:', err);
self.isAuthenticated = false;
} else {
self.events = res.value;
}
});
} else {
self.isAuthenticated = false;
}
}
I am trying to complete a few loops over firebase objects using .forEach and I am also using promises. This isn't working out how I had planned it. My basic problem is that the loops inside of my promises complete well after the promise chain itself completes. Here is my function:
var queue = new Queue(productUpdateQueue, function(data, progress, resolve, reject) {
var incomingUpdateData = data;
var receiptID = incomingUpdateData.receiptID;
var userID = incomingUpdateData.userID;
var oldProductID = incomingUpdateData.oldProductID;
var newProductID = incomingUpdateData.newProductID;
var newReceipt = incomingUpdateData.newReceipt;
var postID = "";
var updateObject = {};
updateObject['usersPrivate/'+userID+'/receipts/'+receiptID+'/items/'+oldProductID] = null;
updateObject['usersPrivate/'+userID+'/receipts/'+receiptID+'/items/'+newProductID] = newReceipt;
clicks.child('VigLink').orderByChild('item').equalTo(oldProductID).once('value', function(cuidSnapshot) {
return cuidSnapshot.forEach(function(cuidSnapshot) {
var cuid = cuidSnapshot.key;
updateObject['clicks/VigLink/'+cuid+'/item'] = newProductID;
console.log('one');
progress(20);
});
}).then(function() {
return userReceiptMetrics.child(userID).child('receipts').child(receiptID).child('items').child(oldProductID).once('value', function(oldSnapshot) {
var data = oldSnapshot.val()
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/items/'+oldProductID] = null
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/items/'+newProductID] = data
if (data != null) {
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/itemIDs/'+newProductID] = now
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/itemIDs/'+oldProductID] = null
};
console.log('two');
progress(40);
});
}).then(function() {
return userReceiptMetrics.child(userID).child('shops').child(oldProductID).once('value', function(oldSnapshot) {
var data = oldSnapshot.val()
updateObject['userReceiptMetrics/'+userID+'/shops/'+oldProductID] = null;
updateObject['userReceiptMetrics/'+userID+'/shops/'+newProductID] = data;
if (data != null) {
updateObject['userReceiptMetrics/'+userID+'/shopIDs/'+newProductID] = now;
updateObject['userReceiptMetrics/'+userID+'/shopIDs/'+oldProductID] = null;
};
console.log('three');
progress(60);
});
}).then(function() {
posts.once('value', function(postSnapshot) {
// use Promise.all and Array#map to wait for all these queries to finish
var allPosts = postSnapshot.val()
var postKeys = Object.keys(allPosts)
return Promise.all(postKeys.map(function(postKey) {
var postID = postKey;
return posts.child(postID).child('items').child(oldProductID).once('value', function(itemSnapshot) {
return itemSnapshot.forEach(function(itemSnapshot) {
var itemData = itemSnapshot.val()
console.log('post snapshot'+ itemData);
updateObject['posts/'+postID+'/items/'+oldProductID] = null
updateObject['posts/'+postID+'/items/'+newProductID] = itemData
});
});
}));
});
}).then(function() {
// Move to next item
return console.log('hey look here'+updateObject['posts/'+postID+'/items/'+newProductID]);
return firebaseRoot.update(updateObject, function(error) {
if (error) {
console.log("Error updating data:", error);
reject()
} else {
progress(100);
// resolve();
console.log('four');
}
});
}).then(function() {
// Move to next item
return console.log('second one'+updateObject['posts/'+postID+'/items/'+newProductID]);
return firebaseRoot.update(updateObject, function(error) {
if (error) {
console.log("Error updating data:", error);
reject()
} else {
progress(100);
// resolve();
console.log('four');
}
});
});
// Finish the task asynchronously
setTimeout(function() {
reject();
}, 10000);
});
And here is the output:

I think I might be using promises incorrectly but I don't know.
I figured out that I should be using Promise.all() in order to wait for my forEach loops to complete. Here is the code I used to solve my problem, enjoy:
var queue = new Queue(productUpdateQueue, function(data, progress, resolve, reject) {
var incomingUpdateData = data;
var receiptID = incomingUpdateData.receiptID;
var userID = incomingUpdateData.userID;
var oldProductID = incomingUpdateData.oldProductID;
var newProductID = incomingUpdateData.newProductID;
var newReceipt = incomingUpdateData.newReceipt;
var postID = "-KZOO0UII67uOmYo6DJh";
var postKeys = [];
var updateObject = {};
updateObject['usersPrivate/'+userID+'/receipts/'+receiptID+'/items/'+oldProductID] = null;
updateObject['usersPrivate/'+userID+'/receipts/'+receiptID+'/items/'+newProductID] = newReceipt;
return clicks.child('VigLink').orderByChild('item').equalTo(oldProductID).once('value', function(cuidSnapshot) {
return cuidSnapshot.forEach(function(cuidSnapshot) {
var cuid = cuidSnapshot.key;
updateObject['clicks/VigLink/'+cuid+'/item'] = newProductID;
progress(10);
});
}).then(function() {
return userReceiptMetrics.child(userID).child('receipts').child(receiptID).child('items').child(oldProductID).once('value', function(oldSnapshot) {
var data = oldSnapshot.val()
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/items/'+oldProductID] = null
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/items/'+newProductID] = data
if (data != null) {
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/itemIDs/'+newProductID] = now
updateObject['userReceiptMetrics/'+userID+'/receipts/'+receiptID+'/itemIDs/'+oldProductID] = null
};
progress(25);
});
}).then(function() {
return userReceiptMetrics.child(userID).child('shops').child(oldProductID).once('value', function(oldSnapshot) {
var data = oldSnapshot.val()
updateObject['userReceiptMetrics/'+userID+'/shops/'+oldProductID] = null;
updateObject['userReceiptMetrics/'+userID+'/shops/'+newProductID] = data;
if (data != null) {
updateObject['userReceiptMetrics/'+userID+'/shopIDs/'+newProductID] = now;
updateObject['userReceiptMetrics/'+userID+'/shopIDs/'+oldProductID] = null;
};
progress(40);
});
}).then(function() {
progress(55);
return posts.orderByChild('receipt').equalTo(receiptID).once('value');
}).then(function(postSnapshot) {
return postSnapshot.forEach(function(post) {
progress(70);
postKeys.push(post.key)
});
}).then(function() {
return Promise.all(postKeys.map(function(postKey) {
return posts.child(postKey).child('items').child(oldProductID).once('value', function(itemSnapshot) {
var itemData = itemSnapshot.val()
updateObject['posts/'+postKey+'/items/'+oldProductID] = null;
updateObject['posts/'+postKey+'/items/'+newProductID] = itemData;
});
})).then(function(results) {
progress(85);
return results;
});
}).then(function() {
return firebaseRoot.update(updateObject, function(error) {
if (error) {
console.log("Error updating data:", error);
reject()
} else {
progress(100);
resolve();
}
});
});
// Finish the task asynchronously

I am writing my first apps with wit.ai using a node.js backend. I found some posts here similar to my question, but not really the answer :
I use a socket.io to communicate with my node script.
The two relevant parts of my node are :
io.sockets.on('connection', function (socket) {
socket.on('message',
function(data) {
var json = JSON.parse(data);
var sid = json['sessionid'];
console.log("Received on sid " + sid);
if (_sessions[sid] == undefined) {
_sessions[sid] = {};
_sessions[sid].context = {};
}
_sessions[sid].socket = socket;
client.runActions(sid, json['text'], _sessions[sid].context, 30)
.then((context) => {
_sessions[sid].context = context;
}
)
.catch((err) =>
{
console.error('Oops! Got an error from Wit: ', err.stack || err);
}
);
}
);
}
);
========
const actions = {
send(request, response) {
const {sessionId, context, entities} = request;
const {text, quickreplies} = response;
return new Promise(function(resolve, reject) {
var session = _sessions[sessionId];
console.log("-------------------------------");
console.dir(context);
console.log("-------------------------------");
session.socket.emit("message", JSON.stringify(response));
return resolve();
});
},
gettaxi ({sessionid, context, text, entities}) {
return new Promise(function(resolve, reject) {
console.log(`Session ${sessionid} received ${text}`);
var quand = firstEntityValue(entities, "quand");
if (!quand && context['quand'] != undefined) quand = context['quand'];
var depart = firstEntityValue(entities, "depart");
var arrivee = firstEntityValue(entities, "arrivee");
if (depart) {
console.log("Found depart");
context.depart = depart;
delete context.missing_depart;
}
else {
context.missing_depart = true;
}
if (arrivee) {
console.log("Found arrivee");
context.arrivee = arrivee;
delete context.missing_arrivee;
}
else {
context.missing_arrivee = true;
}
console.dir(context);
if (quand) {
console.log("Found quand");
context.quand = quand;
delete context.missing_quand;
}
else {
context.missing_quand = true;
}
return resolve(context);
}
);
},
};
All is working rather good, except than my gettaxi receives a undefined sessionid.
It's not the case for the send function that receives the correct sessionid.
What am I doing wrong ?
