App crash when i try to start it

[mathisbdkr]

Hey,

I try to run the app to synchronise my epitech events in my google agenda.

But when I try to run the app this append:

I think i correctly fill the config.json so i don't know why this append
Someone can help me ?

Hello, looks like same as #4

It looks like the first character of the request fetching the login fails because the first character is <, this is probably due to a cookie problem, did you copy the right cookie? What does it look like? (Hides the majority of the cookie if you copy it here).

[mathisbdkr]

Hey, this i my config file

this looks normal to me and i don't see any bad character in the file and i copy the right cookie

[skyf0l]

It looks good, I'll try to dig it before the end of the month.

(And add more information when it crashes, yes the API result is not a valid JSON but why ???????????? gimme more info plz)

[mathisbdkr]

what more information do you need ?

[skyf0l]

Like the raw api response before parsing it as JSON, because it fails as it can't be parsed as JSON

[mathisbdkr]

the raw response before the parsing is "<Response [503]>"

and i get the same response from the function get_all_epitech_events in epitech_calendar.py

[skyf0l]

503 Service Unavailable, I don't understand how this is possible

[mathisbdkr]

maybe it's due to the anti ddos ​​which is on the intranet

[mathisbdkr]

I tried to run the app on epitech wifi and it works. so i think the problem come from the anti ddos ​​on the Epitech intranet

with my own wifi :

with the epitech wifi :

Well done, may we can try to bypass it using a random user agent or by adding more headers?

[mathisbdkr]

I tried to change the user agent and added more headers but it didn't work

[skyf0l]

Thanks for trying this, it's possible that the API/or some intranet routes are behind a strong anti ddos, so there is nothing we can do to bypass it ...

[mathisbdkr]

I think i managed to bypass the anti ddos ​​using selenium, i made a fork if you want to check what i did

[skyf0l]

I just saw that:

# initialize the connection with Epitech intra and wait for the end of the anti-ddos check
def bypass_anti_ddos():
    url = 'https://intra.epitech.eu/'
    driver.get(url)
    sleep(10)

Can we just do this with request (without using selenium) and reinject generated cookies by the https://intra.epitech.eu page in following requests? I would like to avoid integrating selenium to keep this little app simple and light.

Also, I confess that since I'm no longer at epitech, I don't have access to the intra anymore, so I'm less interested in maintaining it. But I'm still open to improvements.

[mathisbdkr]

I used selenium because it open a real google window, and the anti ddos check takes a few seconds before allowing access to the intra. Requests cannot wait for the anti ddos check to finish. So, i don't see how to proceed without Selenium.

[skyf0l]

Oh nooooo, I just saw the new anti-ddos check....
OK, I agree, selenium will be a potential solution, I will approve that

[skyf0l]

HAHAHA I'm thinking the anti-ddos check is easy to bypass, I'll dig that soon 👀
It looks like they are using https://github.com/C0nw0nk/Nginx-Lua-Anti-DDoS

[mathisbdkr]

Ok, i'm gonna look that too
