Python HTML POST with requests

Question

I would like to download some weather information with python from: http://idojarasbudapest.hu/archivalt-idojaras, but I can not see the necessary informations until I don't press the submit button "Mehet". There is two information which I have to submit: Year ('ev'), and month ('ho').

As I understand, I have to POST a request with two parameters: 'ev' and 'ho', then the website should "send me" the requested informations.

The following code which I wrote, prints the original website's html code, not the requested one.

import requests
data= {'ev': '2016','ho': 'Január'}
r = requests.post('http://idojarasbudapest.hu/archivalt-idojaras', data=data)
print (r.text)

The html form looks like this:

The html form

Any idea, how to fix this? Thanks for any answer or suggestion.

Answer 1

From inspecting the post request sent by the browser when the "Mehet" button is pressed, I see that the arguments sent in the POST request have a different form than the ones you are posting via requests.

So perhaps change your code to something like this:

import requests
data= {'ev': '2016','ho': '01', 'button': 'Mehet'}
r = requests.post('http://idojarasbudapest.hu/archivalt-idojaras', data=data)
print (r.text)

Answer 2

To your payload, add 'button': 'Mehet'.

data= {'ev': '2016', 'ho': '01', 'button': 'Mehet'}

• ajlaj25: I have tried this, but that did not solve the problem. What Odysseas mentioned is working. Thanks!
• Luke: @ajlaj25 Oh yeah, I didn't realise, sorry. You have to submit the value of the option, which would be 01 for January. Will edit accordingly.
