bcrypt compareSync returns false even they have same string

I am trying to make login functionality
While I was creating the login function like this
login: (req,res) => {
const body = req.body;
getUserByEmail(body.email,(err,results)=>{
if(err){
console.log(err);
}
if(!results){
return res.json({
sucess: 0,
data: "Invalid email or password 1"
});
}
console.log(body.pw);
console.log(results.pw);
const result = compareSync(body.pw,results.pw);
console.log(result)
if(result){
results.pw = undefined;
const jsontoken = sign({result: results},"1234413",{
expiresIn: "1h"
});
return res.json({
sucess: 1,
message: "login sucessfully",
token: jsontoken
});
}else{
return res.json({
sucess: 0,
data: "Invalid email or password2"
});
}
});
}
Terminal Answer
I console log the body.pw and results.pw but seems like it give me same strings but
I was not sure why it gives me false result even if I have same string for body.pw and results.pw

compareSync compares a password with a hash. You first need to hash the password before comparing it with the plain-text password.
First run
bcrypt.hash(myPlaintextPassword, saltRounds).then(function(hash) {
// Store hash in your password DB.
});
Then you can compare
bcrypt.compare(myPlaintextPassword, hash).then(function(result) {
// result == true
});

Struggling to patch a record in mongodb, unique not working and req.body undefined

I'm learning node.js and it's amazing, especially with mongo, but sometimes I struggle to solve a simple problem, like patching only 1 attribute in my user database.
It's easier to patch something that cannot be unique, but I want to patch an username attribute and I defined it as "unique" in my schema. I don't know why, but MongoDB doesn't care other db entry has the same user, it let me save.
My schema:
/** #format */
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const userSchema = new Schema(
{
username: { type: String, required: true, unique: true },
password: { type: String, required: true },
email: { type: String, required: true, unique: true },
userNumber: { type: Number, required: true },
description: { type: String },
verified: { type: Boolean, default: false },
isAdmin: { type: Boolean, default: false },
isSubscriber: { type: Boolean, default: false },
isDisabled: { type: Boolean, default: false },
acceptedTerms: { type: Number, required: true },
},
{ timestamps: true }
);
module.exports = mongoose.model('User', userSchema);
On my user controllers in node, I want to updateOne({ _id: userId}, { username: myNewUsername} but it always happens, it doesn't take into consideration another db entry can have the username, so I tried a different strategy but it doesn't work:
exports.changeUsername = (req, res, next) => {
// Requirements
const userId = req.params.userId;
const newUsername = req.body.username;
console.log('userId: ' + userId);
console.log('newUsername: ' + req.body.username);
User.findOne({ username: req.body.username })
.then(result => {
console.log(result);
if (result.username) {
const error = new Error('Could not find this sport');
error.code = 'DUPLICATED';
throw error;
}
return;
})
.catch(err => next(err));
// if no username was in use then updateOne
User.updateOne({ _id: userId }, { username: newUsername })
.then(result => {
res.status(200).json({
message: 'username has been updated',
username: result.username,
});
})
.catch(err => next(err));
};
I don't know if I can updateOne at the same time add some find validation. What I am doing wrong? Users cannot have the same username.
On the console, it seems it works, but it throws an extra error I don't understand:
Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
at new NodeError (node:internal/errors:371:5)
at ServerResponse.setHeader (node:_http_outgoing:576:11)
at ServerResponse.header (/Users/username/Sites/pipi-api/node_modules/express/lib/response.js:776:10)
I tried this other approach and it works, but doesn't trigger an error if the record is not unique as I stated in the schema.
// GET ONLY ONE SPORT BY ID
exports.changeUsername = async (req, res, next) => {
// Requirements
const userId = req.params.userId;
const newUsername = req.body.username;
console.log('userId: ' + userId);
console.log('newUsername: ' + req.body.username);
try {
const oldUsername = await User.findOne({ username: newUsername });
if (oldUsername.username) {
throw new Error('Error: its duplicated');
}
const user = await User.findOneAndUpdate(
{ _id: userId },
{ username: newUsername },
{ new: true }
);
console.log('User successfully updated.');
return res.status(200).json({ success: true, user });
} catch (err) {
console.log('ERROR: ', err);
return res.status(400).json({ success: false });
}
};
If I uncomment the code above, it triggers an error if I find a record on the database that matches but it doesn't allow me to continue to my next line of codes I the username is not found on the db.
I get a new error:
userId: 6231bdef334afbde85ed9f43
newUsername: tetete
ERROR: TypeError: Cannot read properties of null (reading 'username')
at exports.changeUsername (/Users/user/Sites/pipi-api/v1/controllers/users/index.js:43:21)

That error is not related to Mongo. It means that you are trying to send a response and the response is already sent.
The issue is because you called both User.findOne and User.updateOne and both of them has .then handler. So the first one of these that finishes will send the actual response. In the moment the second one finished, the response is already send and the error is thrown because you are trying to send response again.
Mongo will throw the error if you try to change username property that some other user already have. You should check if the req.params.userId and req.body.username sent correctly to the backend. Try to console.log() them and check if they are maybe null.
Consider refactoring your handler to use async/await instead of then/catch. You can do it like this:
exports.changeUsername = async (req, res, next) => {
try {
const userId = req.params.userId;
const newUsername = req.body.username;
const user = await User.findOneAndUpdate({ _id: userId }, { username: newUsername }, { new: true });
console.log('User successfully updated.');
return res.status(200).json({ success: true, user });
} catch (error) {
console.log('ERROR: ', error);
return res.status(400).json({ success: false });
}
}

How to fix "Error: Can't set headers after they are sent" in Express

I have recently been developing a MERN application and I have recently came into the trouble that express is saying that I am setting headers after they are sent.
I am using mongo db and trying to update a user profile.
I have tried to comment out my res.send points to find the issue but I have failed to do so.
Here is my post method for updating the user profile:
app.post("/api/account/update", (req, res) => {
const { body } = req;
// Validating and Checking Email
if (body.email) {
var email = body.email;
email = email.toLowerCase();
email = email.trim();
body.email = email;
User.find(
{
email: body.email
},
(err, previousUsers) => {
if (previousUsers.length > 0) {
return res.send({
success: false,
message:
"Error: There is already another account with that email address"
});
} else {
}
}
);
}
// Validating Names Function
function checkName(name) {
var alphaExp = /^[a-zA-Z]+$/;
if (!name.match(alphaExp)) {
return res.send({
success: false,
message: "Error: Names cannot contain special characters or numbers"
});
}
}
checkName(body.firstName);
checkName(body.lastName);
// Making sure that all fields cannot be empty
if (!body.email && !body.firstName && !body.lastName) {
return res.send({
success: false,
message: "Error: You cannot submit nothing"
});
}
// Getting User ID from the current session
UserSession.findById(body.tokenID, function(err, userData) {
// Finding User ID using the current users session token
if (userData.isDeleted) {
return res.send({
success: false,
message:
"Error: Session token is no longer valid, please login to recieve a new one"
});
}
// Deleting the token ID from the body object as user table entry doesnt store tokens
delete body.tokenID;
// Finding the user profile and updating fields that are present
User.findByIdAndUpdate(userData.userId, body, function(err, userInfo) {
if (!err) {
return res.send({
success: true,
message: "Success: User was updated successfully"
});
}
});
});
});
This is the call that I am doing to the backend of the site:
onUpdateProfile: function(fieldsObj) {
return new Promise(function(resolve, reject) {
// Get Session Token
const obj = getFromStorage("the_main_app");
// Defining what fields are getting updated
fieldsObj.tokenID = obj.token;
// Post request to backend
fetch("/api/account/update", {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify(fieldsObj)
})
.then(res => {
console.log("Verify Token - Res");
return res.json();
})
.then(json => {
console.log("Verify Token JSON", json);
if (json.success) {
window.location.href = `/manage-account?success=${json.success}`;
} else {
window.location.href = `/manage-account?success=${json.success}`;
}
});
});
}
Here is my error message that I am getting:
Error: Can't set headers after they are sent.

Can anyone help me with this?
EDIT
I have changed my code, this seems to now work however I feel like its a little messy when put together. Any refactoring tips?
Code:
app.post("/api/account/update", (req, res) => {
// Preform checks on data that is passed through
const { body } = req;
var messages = {
ExistedUser:
"Error: There is already another account with that email address",
NameFormat: "Error: Names cannot contain special characters or numbers",
BlankInputs: "Error: You cannot submit nothing",
accountLoggedOut:
"Error: Session token is no longer valid, please login to recieve a new one",
successfullyUpdated: "Success: User was updated successfully"
};
var usersFound;
if (body.email) {
var email = body.email;
email = email.toLowerCase();
email = email.trim();
body.email = email;
User.find(
{
email: body.email
},
(err, UserCount) => {
usersFound = UserCount;
}
);
}
function capitalize(text) {
return text.replace(/\b\w/g, function(m) {
return m.toUpperCase();
});
}
if (body.firstName) {
body.firstName = capitalize(body.firstName);
}
if (body.lastName) {
body.lastName = capitalize(body.lastName);
}
//Making sure that all fields cannot be empty
if (!body.email && !body.firstName && !body.lastName) {
return res.send({
success: false,
message: messages.BlankInputs
});
}
// Getting User ID from the current session
UserSession.findById(body.tokenID, function(err, userData) {
// Finding User ID using the current users session token
if (userData.isDeleted) {
return res.end({
success: false,
message: messages.accountLoggedOut
});
}
if (userData) {
// Deleting the token ID from the body object as user table entry doesnt store tokens
delete body.tokenID;
// Finding the user profile and updating fields that are present
User.findByIdAndUpdate(userData.userId, body, function(err, userInfo) {
if (userInfo) {
if (!usersFound.length > 0) {
return res.send({
success: true,
message: messages.successfullyUpdated
});
} else {
return res.send({
success: false,
message: messages.ExistedUser
});
}
}
});
}
});
});

You're calling res.send() twice. res.send() ends the process. You ought to refactor such that you call res.write() and only call res.send() when you're done.
This StackOverflow link describes the difference in more detail. What is the difference between res.send and res.write in express?

I believe this is happening, as you're trying to send a response after the first / initial response has already been sent to the browser. For example:
checkName(body.firstName);
checkName(body.lastName);
Running this function twice is going to try and yield 2 different "response" messages.
The product of a single route, should ultimately be a single response.

Thanks for all your help on this issue.
Here is my final code that allowed it to work.
I have also tried to "refactor" it too. Let me know if you'd do something else.
app.post("/api/account/update", (req, res) => {
const { body } = req;
console.log(body, "Logged body");
// Defining objects to be used at the end of request
var updateUserInfo = {
userInfo: {},
sessionToken: body.tokenID
};
var hasErrors = {
errors: {}
};
// Checking that there is at least one value to update
if (!body.email && !body.firstName && !body.lastName) {
var blankError = {
success: false,
message: "Error: You cannot change your details to nothing"
};
hasErrors.errors = { ...hasErrors.errors, ...blankError };
} else {
console.log("Normal Body", body);
clean(body);
console.log("Cleaned Body", body);
updateUserInfo.userInfo = body;
delete updateUserInfo.userInfo.tokenID;
}
// Function to check if object is empty
function isEmpty(obj) {
if (Object.keys(obj).length === 0) {
return true;
} else {
return false;
}
}
// Function to remove objects from body if blank
function clean(obj) {
for (var propName in obj) {
if (obj[propName] === "" || obj[propName] === null) {
delete obj[propName];
}
}
}
// Checking and Formatting Names Given
function capitalize(text) {
return text.replace(/\b\w/g, function(m) {
return m.toUpperCase();
});
}
if (body.firstName) {
body.firstName = capitalize(body.firstName);
}
if (body.lastName) {
body.lastName = capitalize(body.lastName);
}
// Checking and formatting email
if (body.email) {
body.email = body.email.toLowerCase();
body.email = body.email.trim();
// Checking for email in database
User.find({ email: body.email }, (err, EmailsFound) => {
if (EmailsFound.length > 0) {
var EmailsFoundErr = {
success: false,
message: "There is already an account with that email address"
};
hasErrors.errors = { ...hasErrors.errors, ...EmailsFoundErr };
}
});
}
// Getting User Session Token
UserSession.findById(updateUserInfo.sessionToken, function(err, userData) {
// Finding User ID using the current users session token
if (userData.isDeleted) {
var userDeletedError = {
success: false,
message:
"Your account is currently logged out, you must login to change account details"
};
hasErrors.errors = { ...hasErrors.errors, ...userDeletedError };
} else {

Unable to add array to specific part of mongodb

In my database i have the following setup for testdata:
test1 [
[0] { test: Array, comments: Array },
[1] { test: Array, comments: Array }
]
I've since before added the test Array using
var testet1 = { test: newTest1.split(" "), comments: Array };
user.test1.push(testet1);
But I'm for some reason unable to add an array to comments using:
user.test1[0].comments.push(newTest1);
Below is how i define the userSchema, it contains more but i think they are irrelevant in this scenario.
var UserSchema = new Schema({
test1: { type: Array, required: false },
test2: { type: Array, required: false },
test3: { type: Array, required: false }
});
Below is a part of the code that saves the data to the database. The "newTest1" is an array of comments. I've been trying to add a comment to the object but have been unable to.
No error is displayed, the array I'm trying to get into the object is just not added. It's really hard to find the why it's not working when no error is shown.
html:
<form name="edit.test1" ng-submit="ctrl.updateTest1(newComment1, newComment2, ctrl.artikel)">
<div class="form-group">
<label>Kommentarer:</label>
<input class="form-control" type="text" name="test1" placeholder="Comment on first value" ng-model="newComment1" autocomplete="off">
<br>
<input class="form-control" type="text" name="test1" placeholder="Comment on second value" ng-model="newComment2" autocomplete="off">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
Controller:
app.updateTest1 = function(newComment1, newComment2, index) {
app.errorMsg = false; // Clear any error message
app.disabled = true; // Lock form while processing
// Check if username submitted is valid
var userObject = {}; // Create the user object to pass to function
userObject._id = app.currentUser; // Pass current user _id in order to edit
userObject.test1 = [$scope.newComment1, $scope.newComment2, index]; // Set the new username provided
// Runs function to update the user's username
User.editUser(userObject).then(function(data) {
// Behöver jag lägga till något här??
});
};
Userfactory:
userFactory.editUser = function(id) {
return $http.put('/api/edit', id);
};
Creating a new user when a user registers:
router.post('/users', function(req, res) {

user.name = req.body.name; // Save name from request to User object
user.temporarytoken = jwt.sign({ username: user.username, email: user.email }, secret, { expiresIn: '24h' }); // Create a token for activating account through e-mail
// Check if request is valid and not empty or null
if (req.body.username === null || req.body.username === '' || req.body.password === null || req.body.password === '' || req.body.email === null || req.body.email === '' || req.body.name === null || req.body.name === '') {
res.json({ success: false, message: 'Ensure username, email, and password were provided' });
} else {

Why is this? How can i add an array to comments in my db?

how to access variables inside app.get

How can I access a variable or set of variables inside app.get and make it accessible to the whole project? I am trying to capture the information sent from the SMS text, organized into the "messageData" variable, then sent to the "MessageSchema," where it is then sent and stored in the Mongo Database. My issue is that I believe none of the variables(message, number, answer) are truly being found. How can I fix that?
app.js
app.get('/smssent', function(req, res, callback) {
var message = req.query.Body;
var number = req.query.From;
var twilioNumber = req.query.To;
var context = null;
var index = 0;
var contextIndex = 0;
contexts.forEach(function(value)
{
console.log(value.from);
if (value.from == number)
{
context = value.context;
contextIndex = index;
}
index = index + 1;
});
console.log('Recieved message from ' + number + ' saying \'' + message + '\'');
var conversation = new ConversationV1({
username: '',
password: '',
version_date: ConversationV1.VERSION_DATE_2016_09_20

(ABOVE)This is what retrieves the SMS text, and conducts Twilio, Node, and IBM Bluemix.
index.js
router.post('/app', function(req, res, next) {
if (req.body.number &&
req.body.message &&
req.body.answer
) {
// create object with form input
var messageData = {
number: req.body.number,
message: req.body.message,
answer: req.body.answer
};
// use schema's `create` method to insert document into Mongo
Message.create(messageData, function (error, message) {
if (error) {
return next(error);
} else {
return res.redirect('/');
}
});
} else {
var err = new Error('All fields required.');
err.status = 400;
return next(err);
}
});
(ABOVE)This is the code to organize and prepare everything for the "MessageSchema."
message.js
var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');
var MessageSchema = new mongoose.Schema({
number: {
type: String,
required: true,
trim: true
},
message: {
type: String,
required: true,
trim: true
},
answer: {
type: String,
required: true,
trim: true
}
});
var Message = mongoose.model('Message', MessageSchema);
module.exports = Message;
Finally, this is what sends all the info to the DB.
If anyone finds anything or has any tips to improve this code, please let me know, I am open for all the input you can give me!
THANKS!

var messageData = {
number: req.body.number,
message: req.body.message,
answer: req.body.answer
};
This is OK. However, keep in mind that these variables are sent through POST body, not queries like the other one.
queries: ?param = ...
body: (like POST form; hidden from the URL)
If you unsure whether you are passing them alright, you can test that easily by console.info(...) on a certain point; and using Postman to easily test POST behavior.
