I need some help with PubSub...
I need to send a message to a topic every time someone accept cookies in my website. This message should contain the encodedURL that contains the services accepted.
I have this script:
const topicName = "myTopic";
const data = JSON.stringify({
encodeConsentURL:""
});
// Imports the Google Cloud client library
const { PubSub } = require("#google-cloud/pubsub");
// Creates a client; cache this for further use
const pubSubClient = new PubSub();
async function publishMessageWithCustomAttributes() {
// Publishes the message as a string, e.g. "Hello, world!" or JSON.stringify(someObject)
const dataBuffer = Buffer.from(data);
// Add two custom attributes, origin and username, to the message
const customAttributes = {};
const messageId = await pubSubClient
.topic(topicName)
.publish(dataBuffer, customAttributes);
console.log(`Message ${messageId} published.`);
console.log(customAttributes);
}
publishMessageWithCustomAttributes().catch(console.error);
This code works, it sends the message, what I'm finding very hard to do is how to set everything right for running this code in my cookie script. In my cookie script I have a function that writes the cookie, in the same function I would like to send the message, is this possible? Thanks in advance!
It is a bit late, but I don't get it, if you already have a working cookie script and a working publish script, isn't it just about putting them together?
If you still need help I'll be happy to help you
Something like
const runEverything = async () => {
try {
await checkCookiesThing()
await publishMessage()
} catch (e) {
console.error(e)
}
}

Newbie here. I am trying to get a slash command to send an embed with the amount of time it took between the initial message and the message response time. I am getting TypeError: Cannot read properties of undefined (reading 'createdTimestamp') and Error [INTERACTION_ALREADY_REPLIED]: The reply to this interaction has already been sent or deferred. I've jumped around looking at others code trying to find a way to make this work but slash command handling still doesn't make a lot of sense to me. My code block is below. I followed along with https://discordjs.guide so if you have any other suggestions with structure feel free to comment them below. Thank you!
const { SlashCommandBuilder } = require('#discordjs/builders');
const { MessageEmbed } = require('discord.js');
module.exports = {
data: new SlashCommandBuilder()
.setName('ping')
.setDescription('Replies with Pong!'),
async execute(interaction) {
await interaction.reply("Pinging bot...").then (async (msg) =>{
const exampleEmbed = new MessageEmbed()
.setColor('0x0000ff')
.setTitle('Pong! :ping_pong:')
.addField("Time taken: ", `${msg.createdTimestamp - message.createdTimestamp}`)
.setThumbnail("https://78.media.tumblr.com/be43242341a7be9d50bb2ff8965abf61/tumblr_o1ximcnp1I1qf84u9o1_500.gif")
interaction.editReply({ embeds: [exampleEmbed] });
})
},
};
first you need to fetch the reply you send, u can use fetchReply to get the interaction reply. instead of replying with "Pinging bot..." you can defer the reply and then use the createdTimestamp. A basic example of a ping command would be
const { SlashCommandBuilder } = require('#discordjs/builders');
module.exports = {
data: new SlashCommandBuilder()
.setName('ping')
.setDescription('Replies with Pong!'),
async execute(interaction) {
const sent = await interaction.reply({ content: 'Pinging...', fetchReply: true });
await interaction.editReply(`:ping_pong: Pong!\n:stopwatch: Uptime: ${Math.round(interaction.client.uptime / 60000)} minutes\n:sparkling_heart: Websocket heartbeat: ${interaction.client.ws.ping}ms.\n:round_pushpin: Rountrip Latency: ${sent.createdTimestamp - interaction.createdTimestamp}ms`);
},
};
You can customize the response into an embed or however you like. The djs guide has a section on ping command here
I'm really new to OAuth2 so could really use some help. I have a site where users register and login via standard means. However, once they register, I want to connect their Google account so they can view/edit/modify their Google calendars. To this end, I installed react-google-login and have a component on the front-end that logs them into their account. That works fine (here's the code). Please note that the jsx is in styled components, which is why it has odd labels.
return (
<GoogleContainer>
<Logo src={GoogleLogo} />
<GoogleLogin
clientId = {process.env.REACT_APP_CLIENT_ID}
render={(renderProps) => (
<GoogleBtn
onClick={renderProps.onClick}
disabled={renderProps.disabled}
style={styleObj}
>
Connect to Google
</GoogleBtn>
)}
// buttonText='Sign in to Google Calendar'
onSuccess={responseGoogle}
isSignedIn={true}
onFailure={responseError}
cookiePolicy={"single_host_origin"}
responseType='code'
accessType='offline'
scope='openid email profile https://www.googleapis.com/auth/calendar '
/>{" "}
</GoogleContainer>
);
On the backend, I have code that grabs the refresh_token, stores it in a database and then I make a token object that I can send back to the frontend. Here is the code for that -
//This next fx will be used in the CreateTokens fx called by Google Login to identify user by the email captured in scope
const fetchInfo = async (accessToken) => {
const request = await axios.get(
`https://www.googleapis.com/oauth2/v2/userinfo?access_token=${accessToken}`
);
let response = await request;
let email = "";
if (response) {
email = response.data.email;
}
return email;
};
//Get authorization tokens from google calendar when signing into Google
const createTokens = async (req, res, next) => {
try {
const { code } = req.body;
const { tokens } = await oauth2Client.getToken(code);
accessToken = await tokens.access_token;
expiryDate = await tokens.expiry_date;
id_token = await tokens.id_token;
//Make an object with accessToken and expiry data and send to front end
const tokenObj = {
accessToken,
expiryDate,
id_token,
};
//Refresh Token goes to the database
const refreshToken = await tokens.refresh_token;
//We find user by using the scope variable from Google Login (frontend) - fx above
let email = await fetchInfo(accessToken);
if (refreshToken) {
//Parameters to update record by putting refreshToken in database
const filter = { email: email };
const update = { refreshToken: refreshToken };
let user = await User.findOneAndUpdate(filter, update, {
new: true,
});
}
res.send({ tokenObj });
} catch (error) {
next(error);
}
};
That also works fine as I get the refresh_token and store it in the database by user and the tokenObject with the access token gets sent back to the frontend. Here's where I'm confused and can use some help - first of all, I thought I needed to send the token to the frontend to store it but pretty much every time I refresh my page now, the frontend is sending a boatload of information to the console (with tons of information from Google - like the profile, tokens, etc). I don't know what code I wrote that is causing this or if it's a good thing or not. If it's automatically generated, do I even need to have backend code to get the token? Also, I'm getting another message that says " react_devtools_backend.js:3973 Your client application uses libraries for user authentication or authorization that will soon be deprecated. See the Migration Guide for more information." I thought this was up-to-date and not sure what part is deprecated. Ugh - sorry I'm so new to this and very confused. Any help would be much, much appreciated!!
Blockquote
im new using mongo and when i save a new object in my db i use the save method, but when using it and then printing the result, if it was successful i get the object, not someting that i can use to handle any error in the front end
router.post("/post_recipe", async (request, response) => {
const {title, content, author} = request.body;
const new_post = new Posts({title, content, author});
new_post.save(sdfs).then((response) => {
response.json(response);
}).catch(error => response.json(error));
});
doing this on purpose i get the error in the console but its not sending it to the front end to handle it and tell the user that there was a problem
Posts its a scheme, dont know if it has something to do with
Problem is you are using same variable name for your router response and save method response.
Solution
router.post("/post_recipe", async (req, res) => {
const {title, content, author} = req.body;
const new_post = new Posts({title, content, author});
// Getting rid of .then and .catch method
new_post.save((err, savedPost) => {
// Your custom error message
if (err) return res.status(400).json('post not saved due to some problem! Please try again');
// Post that you just saved in db
return res.json(savedPost);
});
This happen due to scope of variable.

So I have this command that shows the riches users in a server this command worked yesterday however recently it has stopped working.
const { MessageEmbed } = require("discord.js");
const { stripIndents } = require("common-tags");
const { prefix } = require("../../botconfig.json");
const db = require('quick.db')
let bal = require('../../database/balance');
let rep = require('../../database/rep');
let work = require('../../database/works');
module.exports = {
config:{
name: "rich",
aliases: ["r"],
category: "currency",
description: "Tells who is rich",
usage: ""
},
run: async (client, message, args) => {
// Get all members of the server before doing anything
message.guild.members.fetch().then(guildMembers => {
let board = [];
for (let key of Object.keys(bal)) {
// Checks if the collection of GuildMembers contains the key.
if (guildMembers.has(key)) {
let value = Object.assign({user: guildMembers.get(key).user}, bal[key]);
board.push(value);
}
}
const emojis = [':first_place:', ':second_place:', ':third_place:', ':small_blue_diamond:', ':small_blue_diamond:']
board = board.sort((a,b) => b.balance-a.balance).splice(0, 5);
let top = board.map((x, i) => `${emojis[i]} **${x.balance.toLocaleString()}** - ${x.user.tag}`).join('\n');
let embed = new MessageEmbed()
.setColor("RANDOM")
.addField(`Richest users in **${message.guild.name}**`, `${top}`)
.setFooter('Switch Version 1.1');
return message.channel.send(embed);
}).catch(console.error)
}
}
The error code when the !rich command is used is as follows:
Guild_Members_Timeout: Members didn't arrive in time
I don't know if this is an issue within the bot or if it is an issue with discord.
Okay I have found the answer to my own problem it seems I needed to add intents to my discord bot to fetch the members.
All I did was add this line of code and it worked.
const intents = new Intents([
Intents.NON_PRIVILEGED, // include all non-privileged intents, would be better to specify which ones you actually need
"GUILD_MEMBERS", // lets you request guild members (i.e. fixes the issue)
]);
const client = new Client({ ws: { intents } });
None of my discord.js guildmember events are emitting, my user caches are basically empty, and my functions are timing out? . In this post it is explained in great detail and that helped me out a lot.TLDR:go to discord developer portal on your particular application ,go to bot , on bot permissions tick whatever is needed and copy the number.Then use this number as a constructor parameter for new Discord.Intents('insert the number here').This worked for me.
I'm trying to use Google Cloud Print(GCP) API, but I can't make it works.
Maybe I've understood bad the workflow because is the first time I'm using the google api, please help me to understand how to make it works.
Initial considerations:
I'm trying to implement it in reactJS, but It is indifferent because the logic to make GCP works is independent of the technology. Then you also can help me understand the workflow.
What exactly I want:
To make my first test, I am looking to get all information about my printer.
What I did:
I created a project in: https://console.developers.google.com
Inside the project created, I created a credential:
create credentials -> OAuth client ID
And I chose Application type: Web, and also configure the restrictions to source and redirection to my localhost.
Manually in https://www.google.com/cloudprint, I added my printer, I made a test printing a PDF and was OK.
I created a project in reactJS to get the information of my printer I've added.
Component:
Explanation:
I'm using a component react-google-login to obtain easily the user accessToken: https://github.com/anthonyjgrove/react-google-login
This component only obtains the access token and save it in localStorage, in a variable called googleToken and it draws a button to call a function to obtain the information about the printer.
code:
import React, { Component } from 'react'
import GoogleLogin from 'react-google-login';
import { connect } from 'react-redux'
import { getPrinters } from '../actions/settings'
class Setting extends Component {
responseGoogle(response) {
const accessToken = response.accessToken
localStorage.setItem('googleToken', accessToken)
}
render() {
return (
<div>
<GoogleLogin
clientId="CLIENT_ID_REMOVED_INTENTIONALLY.apps.googleusercontent.com"
buttonText="Login"
onSuccess={this.responseGoogle}
onFailure={this.responseGoogle}
/>
<button
onClick = {() => {
this.props.getPrinters()
}}
>test printer</button>
</div>
)
}
}
const mapStateToProps = state => {
return {
state: state
}
}
const mapDispatchToProps = dispatch => {
return {
getPrinters() {
dispatch(getPrinters())
}
}
}
export default connect(
mapStateToProps,
mapDispatchToProps
)(Setting)
Action or Function to get information printer:
Explanation:
I'm passing the parameter printerid to get information about that printer.
In authorization, I'm using OAuth ... because in the documentation says that(second paragraph).: https://developers.google.com/cloud-print/docs/appInterfaces
The next two headers I wrote it because I tried solutions as:
Google Cloud Print API: User credentials required
Google Cloud Print User credentials required
code:
import axios from 'axios'
axios.defaults.headers.common['Authorization'] = 'OAuth ' + localStorage.getItem('googleToken')
axios.defaults.headers.common['scope'] = 'https://www.googleapis.com/auth/cloudprint'
axios.defaults.headers.common['X-CloudPrint-Proxy'] = 'printingTest'
const getPrinters = () => {
return () => {
return axios.get('https://www.google.com/cloudprint/printer'
, {
params: {
printeid: 'PRINTER_ID_REMOVED_INTENTIONALLY'
}
}
)
.then(response => {
console.log('response of google cloud print')
console.log(response)
})
}
}
export { getPrinters }
Error:
After all explained before, I got the next error:
User credentials required
Error 403
Note:
I'm using CORS plugin by recommendation of:
Chrome extensions for silent print?
because initially, I had cors error.
Any suggestion or recommendation would be very useful, thanks.
I've resolved my problem, my main problem about User Credential required were because I was using the incorrect access token and It was because I was getting the access token incorrectly.
I'm going to explain my whole solution because there are few examples of codes with this API.
Solutions:
The steps described were Ok until the fourth step where I used the external component react-google-login to trying to get the access token, instead I used googleapis module: Link Github googleapis
Also to avoid CORS problem(and not use CORS chrome plugin) I wrote the requests to Google API in server side.(NODEJS)
I had also a problem in the frontend when I tried to generate a popup to give permission for printer(problems about CORS), my solution was to use this very simple module for authentication: Link Github oauth-open
General scheme:
Explanation:
Knowing I have all data described in my question post(until the third step).
Authentication:
The next step in getting a URL and use it to the user can authenticate.
As I said before I used the module oauth-open in the frontend to generate the popup and only this module need the URL. To get the URL in the backend I used the endpoint /googleurl, where here I used the method generateAuthUrl of the module googleapis to generate the URL.
After that In the frontend, I got the authentication_code(that returned the module oauth-open), I send It to my endpoint /googletoken and here I process the authentication_code to generate access token, refresh token and expiration date with the method getToken of the module googleapis. Finally, these data are stored in the database.
Print:
For print, since the frontend, I send what data I need send to the printer. I used my endpoint /print
In the backend endpoint, my logic was the next:
Recover tokens and expiration date from database, with the expiration date check if the token has expired, and if It has already expired then gets another token and replace the old access token with the new one, replacing also with the new expiration date, to obtain this new data only is necessary call to method refreshAccessToken of module googleapis.Note: the refresh token never expires.
After having the access token updated, use it to send data to the printer with Google route(.../submit)
Code:
All the next codes are in only 1 file
Some data as validation, static variables, error handler, etc, has been removed to better understanding.
Route get URL authentication.
const express = require('express');
const google = require('googleapis');
const router = express.Router();
var OAuth2 = google.auth.OAuth2;
const redirect_url = 'http://localhost:3001/setting'; //Your redirect URL
var oauth2Client = new OAuth2(
'CLIENT ID', //Replace it with your client id
'CLIEND SECRET', //Replace it with your client secret
redirect_url
);
var url = oauth2Client.generateAuthUrl({
access_type: 'offline',
scope: 'https://www.googleapis.com/auth/cloudprint'
});
router.get('/googleurl', (req, res) => {
return res.status(200).send({
result: { googleURLToken: url }
});
});
To get tokens using the authentication code and save these in the database.
const Setting = require('../models/setting'); // My model(Mongoose)
router.post('/googletoken', (req, res) => {
oauth2Client.getToken(req.body.code, function (err, tokens) {
oauth2Client.credentials = tokens;
// If refresh token exits save it
// because the refresh token it returned only 1 time! IMPORTANT
if (tokens.hasOwnProperty('refresh_token')) {
let setting = new Setting();
setting.refreshTokenGoogle = tokens.refresh_token;
setting.expirationTokenGoogle = tokens.expiry_date;
setting.tokenGoogle = tokens.access_token;
setting.save()
.then((settingCreated) => {
return res.status(200).send({
message: 'OK'
});
})
}
});
});
To print
const axios = require('axios');
const moment = require('moment');
router.post('/print',async (req, res) => {
const tickeProperties = {
'version': '1.0',
'print': {
'vendor_ticket_item': [],
'color': { 'type': 'STANDARD_MONOCHROME' },
'copies': { 'copies': 1 }
}
};
const accessToken = await getTokenGoogleUpdated();
axios.get(
'https://www.google.com/cloudprint/submit',
{
params: {
printerid : printerID, // Replace by your printer ID
title: 'title printer',
ticket: tickeProperties,
content : 'print this text of example!!!',
contentType: 'text/plain'
},
headers: {
'Authorization': 'Bearer ' + accessToken
}
}
)
.then(response => {
return res.status(200).send({
result: response.data
});
})
}
);
async function getTokenGoogleUpdated() {
return await Setting.find({})
.then(async setting => {
const refreshTokenGoogle = setting[0].refreshTokenGoogle;
const expirationTokenGoogle = setting[0].expirationTokenGoogle;
const tokenGoogle = setting[0].tokenGoogle;
const dateToday = new Date();
// 1 minute forward to avoid exact time
const dateTodayPlus1Minute = moment(dateToday).add(1, 'm').toDate();
const dateExpiration = new Date(expirationTokenGoogle);
// Case date expiration, get new token
if (dateExpiration < dateTodayPlus1Minute) {
console.log('Updating access token');
oauth2Client.credentials['refresh_token'] = refreshTokenGoogle;
return await oauth2Client.refreshAccessToken( async function(err, tokens) {
// Save new token and new expiration
setting[0].expirationTokenGoogle = tokens.expiry_date;
setting[0].tokenGoogle = tokens.access_token;
await setting[0].save();
return tokens.access_token;
});
} else {
console.log('Using old access token');
return tokenGoogle;
}
})
.catch(err => {
console.log(err);
});
}
I hope It helps you if you want to use Google Cloud Print to not waste a lot of time as I did.
The important part there is a scope https://www.googleapis.com/auth/cloudprint which is not obvious and took one day for me to figure out.
