Inspired by this Youtube Video from Tom Scott.

Write a program or function that prints the current amount of views this question has.

That's it.

Your program may only access the stack exchange api, any other websites are disallowed.

Output

An integer with the exact amount of views this question has at the moment. Outputs with the k for thousand are disallowed.

05AB1E, 46 42 36 bytes

Reading from the question-URL: 36 bytes

’ƒËŠˆ.‚‹º.ŒŒ/q/’žYì•3X&•«.w'Ž‡¡1èþ¨

-6 bytes thanks to @CommandMaster, by reading from this question's URL instead of the API

No direct TIO, since the .w builtin (to access a website) is disabled on TIO. But:

’ƒËŠˆ.‚‹º.ŒŒ/q/’žYì•3X&•«

Try this part online to see the generation of the URL.

'Ž‡¡1èþ¨

Try this part online to see the extraction of the amount of views from the HTML content. (Input doesn't contain the entire HTML content, because the TIO URL would extend 65k+ characters and be too big to post, haha.. xD)

Reading from the API: 46 42 bytes

•3X&•’¸¸.‚‹º.ŒŒ/…é/ÿ?€¼=ƒËŠˆ’žYì.w'š‹¡Åsþ

No direct TIO, since the .w builtin (to access a website) is disabled on TIO. But:

•3X&•’¸¸.‚‹º.ŒŒ/…é/ÿ?€¼=ƒËŠˆ’žYì

Try this part online to see the generation of the API-URL.

'š‹¡Åsþ

Try this part online to see the extraction of the amount of views from the JSON.

Explanation:

’ƒËŠˆ.‚‹º.ŒŒ/q/’
              # Push dictionary string "codegolf.stackexchange.com/q/"
 žY           # Push builtin "https://"
   ì          # And prepend it in front of the url
    •3X&•     # Push compressed integer 203590 (the id of this question)
         «    # Append it to the url
          .w  # Access this URL and read its contents
'Ž‡          '# Push dictionary string "wed"
   ¡          # Split the HTML on this word
    1è        # Get the second item (at index 1)
              #  (i.e. ` 119 times">\n                    <span class="fc-light mr2">Vie`)
      þ       # Only leave the digits (i.e. 1992)
       ¨      # And remove the last digit (2), that was part of the class
              # (after which it is output implicitly as result)

•3X&•         # Push compressed integer 203590 (the id of this question)
 ’¸¸.‚‹º.ŒŒ/…é/ÿ?€¼=ƒËŠˆ’
              # Push dictionary string "api.stackexchange.com/questions/ÿ?site=codegolf",
              # where the `ÿ` is automatically filled with this integer
  žY          # Push builtin "https://"
    ì         # And prepend it in front of the url
     .w       # Access this URL and read its contents
'š‹          '# Push dictionary string "count"
   ¡          # Split the JSON on this word:
              #  (i.e. `...,"view_count":14,"answer_count":2,...` will be split to
              #   [`...,"view_`, `":14,"answer_`, `":2,...`])
    Ås        # Pop and only leave the middle item (i.e. `":14,"answer_`)
      þ       # Pop and only leave its digits (i.e. 14)
              # (after which it is output implicitly as result)

See this 05AB1E tip of mine (sections How to use the dictionary? and How to compress large integers?) to understand why ’ƒËŠˆ.‚‹º.ŒŒ/q/’ is "codegolf.stackexchange.com/q/"; •3X&• is 203590; 'Ž‡ is "wed"; ’¸¸.‚‹º.ŒŒ/…é/ÿ?€¼=ƒËŠˆ’ is "api.stackexchange.com/questions/ÿ?site=codegolf"; and 'š‹ is "count".

  • \$\begingroup\$ @ExpiredData I think it indeed does need it, although I'm not sure. I've only installed 05AB1E locally for the first time a month ago when TIO was having issues for 2 days straight. Without the https:// it doesn't return anything, but it seems it also doesn't seem to work with for some reason.. :/ If I access a website like google (i.e. "www.google.com".w) it reads it HTML-contents just fine, but if I use "https://api.stackexchange.com/questions/203590?site=codegolf"=.w, it seems there is some kind of encoding issue.. :S Here is the output. \$\endgroup\$

  • \$\begingroup\$ Unfortunately I only ever programmed once in Elixir, so I'm not entirely sure why normal HTML websites are read fine, but that JSON api url is having encoding issues.. In the get_url method it uses HTTPoison.get!(url).body to get the website contents (and the url is already casted to a string earlier). \$\endgroup\$

Google Sheets, 99 95 bytes

=Mid(Index(ImportData("https://api.stackexchange.com/questions/203590?site=codegolf"),10),12,99

Sheets will add the trailing parentheses automatically.

ImportData will treat the result as a CSV and split the text into columns.
Index(~,10) pulls the 10th entry from that split result.
Mid(~,12,99) starts at the 12th character and pulls up to the next 99.

So long as the view count doesn't get to 10^99, this will work fine.

Here's a screenshot showing the three steps:

sh, 96 bytes

wget -qO- http://codegolf.stackexchange.com/questions/203590|sed -n 's/.*\(V.*mes\).*/\1/p;540q'

This assumes the presence of wget and sed. We can save 5 bytes (the ;540q part) if we can assume there's no more match of V.*mes on the page -- as of this writing, there isn't, but that may not be true after more submissions. This also assumes the first part of the page is fairly static, and the Viewed XXX times sentence appears uniquely before line 540 (which it currently does).

sh, 101 bytes

wget -qO- http://codegolf.stackexchange.com/questions/203590|sed -n 's/.*\(V.*mes\).*/\1/p;/V.*mes/q

Similar to the above, but this variation does not depend on which line the Viewed XXX times appears -- it terminates after the finding the first one.
