I'm trying to sign up new user, when I'm sending the post request the server register the user well, and I can see them in my data base, but I can't see the success log in my console (I can catch the error and it logs in my console).
Server side code:
var express = require("express");
const { Error } = require("mongoose");
const passport = require("passport");
var router = express.Router();
const User = require("../models/user");
const catchAsync = require("../utils/catchAsync");
router.post(
"/register",
catchAsync(async (req, res) => {
try {
const { email, username, password } = req.body;
const user = new User({ email, username });
await User.register(user, password);
} catch (e) {
throw new Error("Error signing up");
}
})
);
module.exports = router;
Client side code:
const sumbitHandler = async (data) => {
const { username, email, password } = data;
try {
await fetch("http://localhost:9000/users/register", {
method: "POST",
body: JSON.stringify({
username,
email,
password,
}),
headers: {
"Content-Type": "application/json",
},
})
.then((res) => {
if (res && !res.ok) {
throw new Error("ERROR");
}
console.log("Success");
})
.catch((e) => {
console.log(e.message);
});
} catch (e) {
console.log(e.message);
}
};
You are mixing the async/await style and the older .then() Promise-style. Choose one or the other (I strongly recommend async/await)
You are not transforming fetch's response into JSON, leaving it in Promise state.
Your server is never responding to the client! You need to add res.end(), res.send(), res.json() or something.
const sumbitHandler = async (data) => {
const { username, email, password } = data;
try {
const response = await fetch("http://localhost:9000/users/register", {...});
const serverResponse = await response.text(); // or response.json() if your servers sends JSON back
console.log("Success! serverResponse is = ", serverResponse ); // "Done!"
} catch (e) {
console.log(e.message);
}
};
Server :
...
await User.register(user, password);
res.send("Done!"); // or res.json({ status : "ok" }); etc.

This is the error that I get:

here are my codes on server, the statement inside console.log doesnt even show:

the console.log in my client also doesnt show

}
i tried deleting cache and run my app again, recreate a new project on google api (which genereated new ID). they didnt work
i cannot sign in to my app using existing google account. it loads when i clicked and asked me to wait a moment but then nothing happened.
my script.js
function onSignIn(googleUser) {

url: `${baseUrl}/users/googlelogin`,
method: "POST",
data: {
access_token: googleUser.getAuthResponse().id_token,
googleToken: id_token

console.log(response, "ini response dr client")
localStorage.setItem("access_token", response.access_token)
authentication()
})
.fail((err) => {
console.log(err);
swal(
"Oops!", xhr.responseJSON.error[0], "error")
console.log(xhr.responseJSON.error[0])

}
my controller file:

here are the error on console:

Since the verify function is executed asynchronously, the last next() call will be called immediately before the verification is done. Therefore you'll have to call either res.send() or next() inside the callback
function verifyJWT(req, res, next){
const authHeader = req.headers.authorization;
if (!authHeader) {
return res.status(401).send({ message: 'Your access is unauthorized to BookPile' });
}
const token = authHeader.split(' ')[1];
jwt.verify(token, process.env.ACCESS_TOKEN_SECRECT, (err, decoded) => {
if (err) {
return res.status(403).send({ message: 'BookPile authority forbid your access' })
}
console.log('decoded', decoded);
req.decoded = decoded;
next();
})
}
What I am trying to achieve is the following:
I have got a register screen in which the user enters his email and a password. When "register" ist pressed, I want the user to receive an email with a random 6-digit-code which allows him to enter this code on the next page which is the verification screen and with that verify the email.
Everything is set up, but I can only find ways via a generated verification link.
The way I would like to go is:
User enters credentials (email, password)
When pressed on "register" this data is saved to the database under the users collection with an ID and an email with the code is sent.
When this is done, the code can be entered and is somehow compared to the code that is saved somewhere in the database?? Because just sending the generated code to the next screen and store it in a class variable wouldn't be the best approach of achieving this I guess.
After success the users "verified" field is set to true in the database.
I don't really know the best way of programming this.
Please do not bother me for the naming of the routes ;) It's just like that for the moment for simplicity. Because of the same reason I only send response codes of 400 when something went wrong.

Kindly use the NPM Package (two-step-auth)
Use this package in your server index.js and create a route for it, and directly pass in the variables and you can do the rest,
In your app get the data from the form and pass it to your server and then to the package and it will return you an OTP to work with,
Kindly check the full procedures with the example here
Usage
const {Auth} = require('two-step-auth');
async function login(emailId){
const res = await Auth(emailId);
// You can follw the above approach, But we recommend you to follow the one below, as the mails will be treated as important
const res = await Auth(emailId, "Company Name");
console.log(res);
console.log(res.mail);
console.log(res.OTP);
console.log(res.success);
}
const app = express();
app.get('./auth/mailId/CompanyName', async(req, res)=>{
const {emailId} = req.params;
const data = login(emailId);
})
Output
This will help you a lot taking care of the process of verification under the HOOD.
I'm trying to send some data from a React form to my Express back end. To do this I'm using fetch where I'm trying to send some variable data from react. I'm console logging the data before running the fetch to see if it is there, console log can see the data.
My error states
[0] (node:2966) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'message' of undefined
So it seems like my Express back end can't see the variable data.
How I'm sending the data from react
handleSubmit = async e => {
e.preventDefault();
console.log("Submit was pressed!");
if (this.state.email === "") {
}
const { name } = this.state;
const query = this.state.query;
const subject = "kontakt fra nettside";
const message = { name, query };
console.log(message.name, message.text, "data is");
fetch(
"http://localhost:5000/api/email", variabler
{
method: "POST",
cache: "no-cache",
headers: {
"Access-Control-Allow-Origin": "*",
"Access-Control-Allow-Credentials": true,
content_type: "application/json"
},
body: JSON.stringify(message, subject)
}
); //.then(response => response.json());
};
My file for retrieving the data from the front end in Express
const emailConfig = require("./emailConfig")();
const mailgun = require("mailgun-js")(emailConfig);
exports.sendEmail = (recipient, message, attachment) =>
new Promise((resolve, reject) => {
const data = {
from: "Test <test#test.no>", // Real email removed from this post
to: recipient,
subject: message.subject,
text: message.query,
inline: attachment,
html: message.html
};
mailgun.messages().send(data, error => {
if (error) {
return reject(error);
}
return resolve();
});
});
and sendMail.js
const express = require("express");
const sendMail = express.Router();
const emailUtil = require("./emailUtil");
const { sendEmail } = emailUtil;
sendMail.post("/", async (req, res, next) => {
// const { recipient, message } = req.body;
console.log("Request mottatt");
const recipient = "test#test.no";
const message = req.body.message;
try {
await sendEmail(recipient, message);
res.json({ message: "Your query has been sent" });
console.log("Message has been sent");
await next();
} catch (e) {
await next(e);
console.log("nah", e);
}
});
module.exports = sendMail;
I can't figure out where the error is, any ideas? :)
