I have this api which works fine when running locally. But, once it is deployed to Heroku i get a error 503 which is because it tries to target localhost on Heroku's server and not the user's localhost. Is there a way to make this target the user's localhost instead?
The frontend is React. Here's the code in React that fetches this api every 5sec.
axiosFunc = () => {
const { user } = this.props.auth;
console.log(user);
axios.get(`api/avaya/${user.id}`).then((res) => console.log(res));
};
timer = (time) => {
const date = new Date(time);
return `${date.getHours()}:${date.getMinutes()}:${date.getSeconds()}`;
};
componentDidMount() {
this.axiosFunc();
this.interval = setInterval(this.axiosFunc, 5000);
}
componentWillUnmount() {
clearInterval(this.interval);
}
and this is the API on the backend with express
const router = require("express").Router();
const xml2js = require("xml2js");
const Avaya = require("../../models/Avaya");
const User = require("../../models/User");
router.route("/:id").get(async (req, res) => {

EDIT: I was able to fix thanks to #Molda
using fetch instead of axios doesn't result in cors error.

I really don't get the part of (requesting with Axios in API)
Is this a third party API ?
But I suggest you to use (.env) which is a file in your root folder contains the development config like base URLs, expire tokens, API keys ... etc
and when you upload to Heroku you have to make a (.env) in Heroku app and but your config
Let's take an example
in my development mode, my .env looks like
app_url = localhost:4000
port = 4000
db = development_api
db_username = root
db_password =
db_engine = mysql2
in my production mode, my .env looks like
app_url = http://appsomething.heroku.com
port = 80
db = production_api
db_username = root
db_password = 3210LDWAK#AALKQ
db_engine = mysql2
and read more about how to use .ENV

First of all, I apologize for my poor English.
When you press the Write button on the main page, you want to go to the writeBoard page.
Go to writeBoard.ejs only if you are logged in and validate jwt in auth_login.js.
However, res.render does not work after jwt authentication.
What's the problem?
main.js
app.get('/writeBoard', authMWRouter, (req, res) => {
res.render('./basicBoard/writeBoard');
})
auth_login(authMWRouter)
const jwt = require('jsonwebtoken');
const { Account } = require('../models');
module.exports = (req, res, next) => {
console.log(3)
const { authorization } = req.headers;
const [tokenType, tokenValue] = authorization.split(' ');
if (tokenType != 'Bearer') {
res.status(400).send({
result: "fail",
modal_title: "로그인 필요",
modal_body: "로그인을 해주세요."
});
return;
}
try {
const { nickname } = jwt.verify(tokenValue, 'DongGyunKey');
Account.findByPk(nickname).then((account) => {
res.locals.account = account;
next();
});
console.log(1)
} catch (err) {
res.status(400).send({
result: "fail",
modal_title: "로그인 필요",
modal_body: "로그인을 해주세요."
});
return;
}
}
basicBoard.ejs (my main page)
function move_writeBoard() {
const write_ajax = new XMLHttpRequest();
var myModal = new bootstrap.Modal(document.getElementById("noticeModal"), {});
write_ajax.onload = () => {
if (write_ajax.status == 400 || write_ajax.status == 401) {
responseTxt = JSON.parse(write_ajax.responseText);
const modalTitle = document.querySelector('#msgTitle');
var mtTxt = document.createTextNode(responseTxt['modal_title']);
modalTitle.appendChild(mtTxt);
const modalBody = document.querySelector('#msgbody');
var mbTxt = document.createTextNode(responseTxt['modal_body']);
modalBody.appendChild(mbTxt);
document.getElementById('exitButton').setAttribute('onclick', 'window.location.href="/login"');
document.getElementById('correctButton').setAttribute('onclick', 'window.location.href="/login"');
myModal.show();
}
}
write_ajax.onerror = () => {
console.error(write_ajax.responseText);
}
write_ajax.open('GET', '/writeBoard');
write_ajax.setRequestHeader('authorization', 'Bearer ' + localStorage.getItem("token"));
write_ajax.setRequestHeader('Content-Type', 'application/json');
write_ajax.send();

I have found this code on one of the tutorials to catch SMS from Twilio and pass it to ur webdriver test. I need help to catch the sms using Cypress. I need help using async-await instead of browser.call with Cypress.
const accountSid = 'YOUR_SID';
const authToken = 'YOUR_TOKEN';
const client = require('twilio')(accountSid, authToken);
describe('OTP', () => {
it('Login with OTP', () => {
const username = $('#login_field');
const pass = $('#password');
const signInBtn = $('input[type="submit"]');
const otpField = $('#otp');
const verifyBtn = $(
'form[action="/sessions/two-factor"] button[type="submit"]'
);
browser.url('https://github.com/login');
username.setValue('your_email#mail.com');
pass.setValue('your_pass123');
signInBtn.click();
// Get OTP ...
const otp = browser.call(() => {
return new Promise((resolve, reject) => {
try {
client.messages.list({ limit: 1 }).then((messages) =>
messages.forEach((m) => {
// console.log(m.body.match(/\d+/)[0]);
resolve(m.body.match(/\d+/)[0]);
})
);
} catch (error) {
reject(error);
}
});
});
otpField.setValue(otp);
verifyBtn.click();
expect(browser).toHaveUrl('https://github.com/');
});
});
Manzeel Uprety you can try my solution:
const accountSid = 'AC793683c4982a14f01714321bd3f90ca7';
const authToken = '819068e54369ac58bb8aad976fa517bc';
const githubEmail = 'your_github_email'
const githubPassword = 'your_github_password'
describe('Login with github credentials', () => {
beforeEach(()=>{
cy.visit('https://github.com/login');
cy.get('#login_field').type(githubEmail);
cy.get('#password').type(githubPassword);
cy.get('input[type="submit"]').click()
})
it('Get SMS and apply it in 2FA form', () => {
cy.request({
method: 'GET',
url: `https://api.twilio.com/2010-04-01/Accounts/${accountSid}/Messages.json`,
auth: {
username: accountSid,
password: authToken,
AuthMethod: 'BasicAuth',
}
})
.its('body').then((res) => {
cy.wait(1500) //wait for SMS
const otpcode = res.messages[0].body.substring(0, 6)
cy.get('#otp').type(otpcode);
cy.url().should('eq', 'https://github.com/');
})
});
});
Path 1 - Match_Creator/cricket/matchList;
Path 2 - Match_Creator/cricket/completedMatchList;
I have a collection called matchList (Path 1) In which i am having a doc called c434108.
Now I want to move this doc(c434108) to Path 2;
/* eslint-disable promise/catch-or-return */
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const { db } = require("./db/index");
const createCompletedMatchListDoc = (request, response) => {
completedMatchDocsData();
};
function completedMatchDocsData() {
createNewCompletedMatchDocs()
}
function getOldCompletedMatchDocs(){
var completedMatchesRef = db
.collection("Match_Creator")
.doc("cricket")
.collection("matchList");
var completedMatchDocData;
var completedMatchDataArr = [];
return new Promise(resolve => {
let query = completedMatchesRef
.where("status", "==", "live")
.get()
.then(snapshot => {
// eslint-disable-next-line promise/always-return
if (snapshot.empty) {
console.log("No matching documents.");
return;
}
snapshot.forEach(doc => {
completedMatchDocData = doc.data();
completedMatchDataArr.push(completedMatchDocData);
resolve(completedMatchDataArr);
});
console.log("sarang", completedMatchDataArr[2]);
})
.catch(err => {
console.log("Error getting documents", err);
});
});
}
const createNewCompletedMatchDocs = (async(change, context) => {
let completedMatchData = await getOldCompletedMatchDocs();
console.log('aman', completedMatchData[1]);
const newValue = change.after.data();
const previousValue = change.before.data();
const st1 =newValue.status;
const st2 = previousValue.status;
console.log('I am a log entry' + st1 + ' ' + st2);
var data = completedMatchData[0];
return db.collection('Match_Creator').doc('cricket').collection('completedMatchList').add(data)
.catch(error => {
console.log('Error writting document: ' + error);
return false;
});
})
module.exports = createCompletedMatchListDoc;
And After copy this doc(c434108) i want to delete this doc(c434108) from path 1.
And My index.js file is:
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const storeMatchData = require("./liveScoring");
const createCompletedMatchListDoc = require("./completedMatchList");
var http = require("https");
module.exports = {
liveScoring: functions.https.onRequest(storeMatchData),
createCompletedMatchListDoc: functions.https.onRequest(
createCompletedMatchListDoc
)
};
I am able to solve my problem.
This is my completeMatchList.js file
/* eslint-disable promise/catch-or-return */
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const { db } = require("./db/index");
const createCompletedMatchListDoc = (request, response) => {
completedMatchDocsData();
};
function completedMatchDocsData() {
setNewCompletedMatchDocs()
}
function getOldCompletedMatchDocs(){
var completedMatchesRef = db
.collection("Match_Creator")
.doc("cricket")
.collection("matchList");
var completedMatchDocData;
var completedMatchDataArr = [];
return new Promise(resolve => {
let query = completedMatchesRef
.where("status", "==", "live")
.get()
.then(snapshot => {
// eslint-disable-next-line promise/always-return
if (snapshot.empty) {
console.log("No matching documents.");
return;
}
snapshot.forEach(doc => {
// completedMatchDocData = doc.data();
completedMatchDocData = {
docId: "",
docData: ""
}
completedMatchDocData.docId = doc.id;
completedMatchDocData.docData = doc.data();
completedMatchDataArr.push(completedMatchDocData);
resolve(completedMatchDataArr); // Here i am getting the data and pushing it in array
});
console.log("sarang", completedMatchDataArr);
})
.catch(err => {
console.log("Error getting documents", err);
});
});
}
const setNewCompletedMatchDocs = (async () => {
let getCompletedMatchData = await getOldCompletedMatchDocs();
// console.log("balram", getCompletedMatchData[0].docId);
let newCompletedMatchDocRef = db.collection("Match_Creator").doc("cricket").collection("completedMatchList").doc(getCompletedMatchData[0].docId);
return newCompletedMatchDocRef.set(getCompletedMatchData[0].docData); //set/copy the data to new path.
})
This is my main index.js file
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const storeMatchData = require("./liveScoring");
const createCompletedMatchListDoc = require("./completedMatchList");
const { db } = require("./db/index");
var http = require("https");
module.exports = {
liveScoring: functions.https.onRequest(storeMatchData),
createCompletedMatchListDoc: functions.https.onRequest(
createCompletedMatchListDoc
)
};
Now after copy document data to a new path i will delete the previous document. For deleting the document i have not written the function.
I'm not seeing anything that would allow you to move a document between collections(someone correct me if I'm wrong). You have to copy from the old collection to the new one and then remove the old one.
This is another post on StackOverflow that is running into this same issue and someone provided Java code on how to implement it.
EDIT: Updated link.
Hope this helps.
I am working on solutions using which i can send desktop push notification to subscribed clients.
I have created basic solution in where whenever user click on button i ask user for whether they want to allow notifications for my app or not!
I am getting an error of "Registration failed - permission denied" whenever i click on button for first time.

I can think of three reasons that the permission is denied
1) your site is not on https (including localhost that is not on https), the default behaviour from chrome as far as i know is to block notifications on http sites. If that's the case, click on the info icon near the url, then click on site settings, then change notifications to ask
2) if you are on Safari, then safari is using the deprecated interface of the Request permission, that is to say the value is not returned through the promise but through a callback so instead of
Notification.requestPermission().then(res => console.log(res))
it is
Notification.requestPermission(res => console.log(res))
3) Your browser settings are blocking the notifications request globally, to ensure that this is not your problem run the following code in the console (on a secured https site)
Notification.requestPermission().then(res => console.log(res))
if you receive the alert box then the problem is something else, if you don't then make sure that the browser is not blocking notifications requests
