Download file from website without url

Hello,

How do I download a file from a website without having a url?

More details:

I have the url for the "main" website where the file is located (it's in swedish): https://www.smhi.se/data/meteorologi/ladda-ner-meteorologiska-observationer/#param=precipitation24HourSum,stations=core,stationid=181970

The file that I want to download is the file you download when you click: 'Ladda ner data för de senaste fyra månaderna (.csv)'.

The problem that I have is that I can't seem to find the url for the download, since you need a url for the command 'webread' I am unable to download the file that I want with Matlab.

So I wonder if anyone knows how I can download the file without a url or if anyone is able to find the url for the download or if it's simply impossible without a url.

What you need to do, is use the inspection tools of your browser to track the requests your browser makes when downloading a file.

That allows you to extract the URL:

url='https://opendata-download.smhi.se/stream?type=metobs&parameterIds=5&stationId=181970&period=latest-months';
fn = websave('test.csv',url)

fn = '/users/mss.system.oM9snL/test.csv'

contents = fileread(fn);
disp(contents(1:floor(end/20)))

Stationsnamn;Stationsnummer;Stationsnät;Mäthöjd (meter över marken)
Esrange;181970;SMHIs stationsnät;2.0

Parameternamn;Beskrivning;Enhet
Nederbördsmängd;summa 1 dygn, 1 gång/dygn, kl 06;millimeter

Tidsperiod (fr.o.m);Tidsperiod (t.o.m);Höjd (meter över havet);Latitud (decimalgrader);Longitud (decimalgrader)
1977-10-01 00:00:00;1993-12-31 23:59:59;335.0;67.8947;21.0694
1994-01-01 00:00:00;1999-07-01 23:59:59;330.0;67.8947;21.0694

Note that the website clearly doesn't want you to do this, so you should limit what you do.
