My school has a website for homework called pronote (no problem if you don't know it). After logging in on parisclassenumerique.fr (works with selenium but I cant get requests to work), I want to read one of the packets that is sent: All the info about my day, my homework, etc. are in there and it is the perfect file: header request response stack trace

The file's download address looks random. The login works only for a limited period of time in the same browser.

Any ideas for using that tool of Firefox or same of Chrome?

Thanks!

Most likely, what you're looking at is going to require some sort of
login token, a cookie or equivalent. It's not going to be easy to
replicate that in Python without actually providing your login
credentials.

I'd say the easiest approach is going to be a hybrid of Python to do
your processing, with some JavaScript to collect the request
information. But it all depends on how much you want to automate this,
and how much effort you're willing to put in. For instance, you could
write a Chrome extension that is aware of the traffic, or perhaps it'd
be sufficient to just paste some JavaScript code into the Dev Tools
console before you send the request.

Hello,
Thanks for you answer!
Actually my goal is not to automatically get the file once I open the page, but more to periodically check the site and get a notification when there's new homework or, at the morning, know when an hour is cancelled, so I don't want to have to open the browser every time.
I have pretty good javascript knowledge so if you could better explain that idea, it would be a great help.

Ahh, now I better understand your purpose. Hmm.

First and by far the best option would be to see if there's any sort
of (documented or undocumented) API. See if you can figure out how the
requests are being done, and try to find a pre-request request that is
hinting at the download address. (You might have to do some
exploration here.)

Secondly, it may be possible to do an occasional manual check, but
then keep your login cookie alive by periodic queries by your
automated script. No idea how well that would work.

Third, your worst case might be to do most of the work in JavaScript,
maybe as a Chrome extension, but then have it call a Python script
(via an HTTP request, since that's how JavaScript in a browser can
best notify anything) to do whatever extra work you need Python for.
Not sure how well that would work.

Unfortunately it depends a LOT on the homework server you're working
with, so it's hard to be specific. On the plus side, though, you're
going to learn all kinds of things along the way! Or maybe that's
another downside, depending on how Daily WTF-worthy the site is....

Hello,

I'm not 100% sure but I think that I understand what you are trying to
do. I faced the same problem a few months ago.

I wanted to know when a particular blog posted a new article.

My plan was to query the blog every day running a python script, get the
list of articles it has and comparing them with the list of the previous
day.

I used Selenium (https://selenium-python.readthedocs.io/) and on top of
that I implemented a thin layer to manipulate the web page called
"selectq" (https://github.com/SelectQuery/sQ)

You could write a similar script.

Using Selenium or selectq will open a web browser but given that it is
fully automated, it should not be a problem (well, yes, it may run a
little slow however).

The good side is that both can inject javascript if you have to.

Would this work for you or am I saying nonsense?

Thanks!
Martin.

It seems there's a smartphone app that does what you want, so this wheel
may already have been invented (in a manner of speaking).

Maybe you are already aware of this and are looking for a way to improve
your hacking skills, or perhaps you don't have a
smartphone--unlikely!--or want your notifications on your computer
rather than your phone, etc.

Notifications

Afin de rester informé en temps réel de tous les événements qui vous
concernent (actualités, messages, blogs, espace documentaire…), il est
nécessaire d’activer sur votre mobile les notifications pour
l’application (par défaut, à votre arrivée sur l’application, toutes
les notifications sont activées).

Hi,
Seems like that could be a method of doing things. Just one clarification: the website has unselectable text, looks like it's an image strangely generated, so if I can get the packet with it, it would be perfect. As I said (I think), logging in with Selenium was already possible, and I could get a screenshot of the page after logging in.
If you got this working like a packet listener in browser capable of seeing packet data, I'd gladly accept the code.
I've tried to do this for 3 years now (since I came into that school basically), looks like it's coming to an end!
Thanks!

@Curt: That is notifications for the ENT app, I want the notifications for the app named ProNote. ENT is for e-mails and Pronote for homework, quotes, etc.

Notifications dans PRONOTE 
Paramétrer les notifications
Vous êtes notifié lorsque vous recevez un message, une information, un
sondage ou un document.

1. Rendez-vous dans le menu Mes préférences > communication >
Messagerie.

2. Cochez le ou les modes de notification souhaités.

....

Notification via l'application (parents / élèves / professeurs)
Dès la rentrée, un système de notifications sur mobile permettra aux
parents, élèves et professeurs d'avoir une notification sur leur
téléphone à l'arrivée d'un nouveau message ou d'une nouvelle
information.

Already tried this, only works for messages and not for homework etc.

Notifications pour Pronote vous permet de recevoir des notifications
push lorsqu'une nouvelle note ou un nouveau *devoir* est ajouté sur
Pronote ! Soyez informés en direct et évitez de vous connecter 50 fois
par semaine pour voir si le prof d'histoire géo a enfin mis les notes du
contrôle 😄

Et voilà l'appli qui fait tout !

"unselectable text" not necessary means that it is an image. There is
a CSS property that you can change to make a text
selectable/unselectable.

And if it is an image, it very likely that it comes from the server as
such, so "intercepting" the packet coming from there will be for
nothing: you will have the same image.

About the "packet listener", you could setup a proxy between your
browser and the server and use the proxy to see the messages. "Burp" is
the classical tool for this.

But I have the feeling that the solution is easier.

Try the following: do it manually but take note of the steps you do.

Example:

1) Go to page https://www.parisclassenumerique.fr
2) Click in the upper-right menu button and choose "Tutoriels". Now the
URL is
https://www.parisclassenumerique.fr/lutece/jsp/site/Portal.jsp?page_id=9
3) Then click in "Comment démarrer sur PCN ?", on the left panel

.... and so on.

Basically you can then translate those steps to Selenium/selectq and
automate them. It's here where I could help you but I cannot do much
without more info because I don't know which page you are looking and in
which link you are trying to click and stuff like that.

Ok,
So here's a screenshot:
https://ibb.co/2dtGr3c
1 is the website's scrollbar and 2 is Firefox's scrollbar.
Seems like it uses a strange embed thing.
The packet follows:
https://pastebin.com/2qEkhZMN
@Martin Di Paola: I sent you the pastebin password per email so that you're the only one who can access it, I just don't want anyone who passes by to be able to see my quotes...
What is that CSS tag? I could try to disable it in the inspector.

Found this:
https://pastebin.com/fvLkSJRp
with use-select tags.
I'll try to use selenium and select the page.
But using the JSON packet that's sent will still be more practical.
