I have this route on my backend:
const { id } = req.params
if (!id) return res.status(500).send({ message: 'Invalid request' })
const videoPath = `videos/${id}.mp4`
const videoStat = fs.statSync(videoPath)
const fileSize = videoStat.size
const videoRange = req.headers.range
if (videoRange) {
const parts = videoRange.replace(/bytes=/, "").split("-");
const start = parseInt(parts[0], 10);
const end = parts[1]
? parseInt(parts[1], 10)
: fileSize - 1;
const chunksize = (end - start) + 1;
const file = fs.createReadStream(videoPath, { start, end });
const header = {
'Content-Range': `bytes ${start}-${end}/${fileSize}`,
'Accept-Ranges': 'bytes',
'Content-Length': chunksize,
'Content-Type': 'video/mp4',
};
res.writeHead(206, header);
file.pipe(res);
} else {
const head = {
'Content-Length': fileSize,
'Content-Type': 'video/mp4',
};
res.writeHead(200, head);
fs.createReadStream(videoPath).pipe(res)
}
I already have a middleware to detect if the user is authenticated or not. It works fine, but I don't really know how to implement it on the front-end. I was trying something like this:
<video crossOrigin="anonymous" id="videoPlayer" controls>
<source src={process.env.NEXT_PUBLIC_BACKEND_URL + '/v1/video/get/' + props.videoId} type="video/mp4" />
</video>
But it doesn't really work, since the request is going without the token. What could I do to make the front-end request authenticated using the token from cookies?
Solved by using crossOrigin="use-credentials" and then on the backend, instead of reading the token from the headers in this specific case, im getting the token from the cookies.

I am trying to download a HLS video once I am loggedon (cookies)
HLS videos are made of .m3u8 file and squeces of 00001.ts, 00002.ts ... files
I tried 2 methods
I download the files using the downloader
const client = await page.target().createCDPSession();
await client.send('Page.setDownloadBehavior', {
behavior: 'allow',
downloadPath: '/',
});
await page.evaluate((link) => {
location.href = link;
}, link);
This works for the .m3u8 file, however, it does not work for 00001.ts : because the browser opens these files and does not download them.
I have no idea how to force the downloading of .ts files and not opening them
I tried another way (from https://help.apify.com/en/articles/1929322-handling-file-download-with-puppeteer)
But this did not work either
await page.setRequestInterception(true);
await page.goto('https://eedols.com/m3u8/20221205130402-SiBOhsUsJbTdZLP-DfqGGLn5cF-6-l.m3u8');
const xRequest = await new Promise(resolve => {
page.on('request', interceptedRequest => {
interceptedRequest.abort(); //stop intercepting requests
resolve(interceptedRequest);
});
});
const options = {
encoding: null,
method: xRequest._method,
uri: xRequest._url,
body: xRequest._postData,
headers: xRequest._headers
}
/* add the cookies */
const cookies = await page.cookies();
options.headers.Cookie = cookies.map(ck => ck.name + '=' + ck.value).join(';');
/* resend the request */
const response = await request(options);
It is stuck.
Any idea on that ?
I am trying to send email using dialogflow intents from my gmail. But it throws the same error every time and I am unable to understand the issue behind this. The same thing stand alone from my code is able to send emaail to various email addresses. So i guess the code works just fine . Please have a look at my code .
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const nodemailer = require("nodemailer");
const admin = require("firebase-admin");
const axios = require("axios");
admin.initializeApp({
credential:admin.credential.applicationDefault(),
databaseUrl:'ws://***************/'
});
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
function welcome(agent) {
agent.add(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
function emailSend(){
const email= agent.parameters.email;
const name= agent.parameters.name;
const subject= agent.parameters.subject;
const message = agent.parameters.message;
}
const nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: '*****#gmail.com',
pass: '***********'
}
});
var mailOptions = {
from: 'Mamuni',
to: 'email' ,
subject: 'subject' ,
text: 'message'
};
transporter.sendMail(mailOptions, function(error, info){
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
let intentMap = new Map();
intentMap.set('emailSend',emailSend);
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
agent.handleRequest(intentMap);
});
The error probably is indicative that your code is not reachable or probably not being served via a HTTPS endpoint. I suggest the following:
Is the code available over a publicly accessible endpoint?
If the above is yes, is it being served over a secure channel i.e. HTTPS?
I have the following function working from an Angular component (in an Electron application) using HttpClient:
var auth = "Bearer" + "abdedede";
let header = new HttpHeaders({ "Content-Type": 'application/json', "Authorization": auth});
const requestOptions = {headers: header};
const url = 'https://reqres.in/api/users?page=1';
this.http.get<any>(url, requestOptions).toPromise()
.then(response=> {
//...
alert(JSON.stringify(response));
});
}
Now, here is a call from the electron side which calls the same endpoint but without the Authorization and Content-Type in the header:
let buffers:any = [];
const { net } = require('electron')
const request = net.request({
method: 'GET',
url: 'https://reqres.in/api/users?page=1'})
request.on('response', (response) => {
console.log(`HEADERS: ${JSON.stringify(response.headers)}`)
response.on('data', (chunk) => {
buffers.push(chunk);
})
response.on('end', () => {
let responseBodyBuffer = Buffer.concat(buffers);
let responseBodyJSON = responseBodyBuffer.toString();
responseBodyJSON = responseBodyJSON;
})
})
request.end()
(This latter function is thanks to a poster replying here: In an Electron Application I am successfully making an HTTP GET request from an Angular component. How can I do the same thing from the Electron side?)
My question is, could anybody please advise\show me how to add in the Authorization and Content-Type Header info to this call so that it replicates what the Angular version does - i.e. by passing the requestOptions data in the GET call?
Thanks.
I have found it. I needed to add:
request.setHeader("content-type", "application/json"); request.setHeader("Authorization", auth);
before I call:
request.on('response', (response) => {
At the end of the waterfall-dialog in "summary" (i.e., the last if statement) i want to automatically make a post request without making an API call in Postman, is eventListener the way? How to include it?
async summaryStep(step) {
if (step.result) {
// Get the current profile object from user state.
const userProfile = await this.userProfile.get(step.context, new UserProfile());
userProfile.name = step.values.name;
//the same for other step values(email, doctor, date)
let msg = `you want a date with dr. ${userProfile.doctor} , and your name is ${userProfile.name}.`;
if (userProfile.date !== -1) {
msg += `you have an appointment the: ${userProfile.date}.`;
}
await step.context.sendActivity(msg);
let msg1 = `"${userProfile.date}"`;
if (msg1) {
let z = JSON.stringify(userProfile.name);
//and also the other rows to go in the database(email, doctor, date)
var name = JSON.parse(z);
//and also the other rows to go in the database(email, doctor, date)
//this actually works but only if i use postman
var urlencoded = bodyparser.urlencoded({ extended: false });
app.post('/id', urlencoded, (req, res) => {
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
mysqlConnection.query("INSERT INTO users(name, email, doctor, date) VALUES('" + userProfile.name + "','" + userProfile.password + "','" + userProfile.doctor + "','" + userProfile.date + "')", function (err, result, rows) {
if (err) throw err;
console.log("Yeah! record inserted");
console.log(name);
res.send(result);
});
});
const port = process.env.PORT || 8080;
app.listen(port, () => console.log(`Listening on port ${port}..`));
}
} else {
await step.context.sendActivity('Thanks. Your profile will not be kept. Push enter to return Menu');
}
return await step.prompt(CONFIRM_PROMPT3, `is that true? ${step.result}`, ['yes', 'no']);
// this if statement should "fire" the post request...
if (step.result == 'yes') {
return await step.context.sendActivity(`we will contact you soon ${userProfile.password}.`);
}
return await step.endDialog();
}
Per my understanding , you want to know how to call an POST API from Azure bot async function. Pls try the code below in your async summaryStep function to send the post request based on your requirement.
var rp = require('request-promise');
var options = {
method: 'POST',
uri: 'http://localhost:8080/id',
body: {
fieldCount:0,
affectedRows:1,
//your other body content here...
},
json: true,
headers: {
'content-type': 'application/json' //you can append other headers here
}
};
await rp(options)
.then(function (body) {
console.log(body)
})
.catch(function (err) {
console.log(err)
});
}
Hope it helps .
A
nd if there is any further concerns or misunderstand , pls feel free to let me know.
The answer is to move your app.post API endpoint to your index.js file where your bot is already running on a server. Simply spin up a new "server" and "port" making the endpoint available. Then, in your summaryStep (axiosStep in my example), make your API call using Axios, request-promise, or what have you, to post your data. When the API is hit, the data will be passed in and processed.
In the code below, when the API is hit the passed in data is used in a sendActivity posted back to the bot. In your case, your passed in data would be used for the database call in which you could use the returned response in the sendActivity.
Your code would look something like the following. Please note, the post actions are simplified for the sake of the example. You would need to update the post actions to make your mySql queries. This sample also makes use of restify for the server (standard for Bot Framework bots) and uses the same port as the bot, but this can easily be updated to use Express and/or another port.
Hope of help!

I am trying to download an OBJ file generated from SVF file, using the Autodesk.Forge .NET API method GetDerivativeManifest (C#). The OBJ file has been created successfully. However, the method does not provide a Stream that I can use to retrieve the file and save it locally.
How can I get the OBJ file?
I don't have a C# sample ready to give you, but I hit the same issue with the Node.js SDK. I worked around by implementing the REST call myself:
download (token, urn, derivativeURN, opts = {}) {
// TODO SDK KO
//this._APIAuth.accessToken = token
//
//return this._derivativesAPI.getDerivativeManifest(
// urn,
// derivativeURN,
// opts)
return new Promise((resolve, reject) => {
const url =
`${DerivativeSvc.SERVICE_BASE_URL}/designdata/` +
`${encodeURIComponent(urn)}/manifest/` +
`${encodeURIComponent(derivativeURN)}`
request({
url: url,
method: 'GET',
headers: {
'Authorization': 'Bearer ' + token.access_token
},
encoding: null
}, function(err, response, body) {
try {
if (err) {
return reject(err)
}
if (response && [200, 201, 202].indexOf(
response.statusCode) < 0) {
return reject(response.statusMessage)
}
if (opts.base64) {
resolve(bufferToBase64(body))
} else {
resolve(body)
}
} catch(ex) {
console.log(ex)
reject(ex)
}
})
})
}
Here is how I invoke that method within my endpoint:
/////////////////////////////////////////////////////////
// GET /download
// Download derivative resource
//
/////////////////////////////////////////////////////////
router.get('/download', async (req, res) => {
try {
const filename = req.query.filename || 'download'
const derivativeUrn = req.query.derivativeUrn
// return base64 encoded for thumbnails
const base64 = req.query.base64
const urn = req.query.urn
const forgeSvc = ServiceManager.getService(
'ForgeSvc')
const token = await forgeSvc.get2LeggedToken()
const derivativesSvc = ServiceManager.getService(
'DerivativesSvc')
const response = await derivativesSvc.download(
token, urn, derivativeUrn, {
base64: base64
})
res.set('Content-Type', 'application/octet-stream')
res.set('Content-Disposition',
`attachment filename="${filename}"`)
res.end(response)
} catch (ex) {
res.status(ex.statusCode || 500)
res.json(ex)
}
})
Hope that helps
