Re: issue with SWH ratelimit (authorization via HTTP header)

[zimoun]

Hi,

Thanks to Ricardo on #guix-hpc, the issue is:

    `((authorization . (Bearer ,token))))

and not ’bearer’.  Maybe the process can help.

It is misleading because the documentation [1] says to use:

--8<---------------cut here---------------start------------->8---
Enter `,help' for help.
scheme@(guix-user)> ,use(web http)
scheme@(guix-user)> (parse-header 'authorization "Bearer eyJh…")
$1 = (bearer eyJh…)
--8<---------------cut here---------------end--------------->8---

But it is not what

    (http-request URL #:method 'POST #:headers `((authorization . (bearer 
,token))))

returns.

Let open a terminal and run ’emacs-simple-httpd’ as server.  The buffer
*httpd* lists what is happening.  In another terminal, let run the
request above.  Tadam!

--8<---------------cut here---------------start------------->8---
(request
 (date "Thu, 14 Oct 2021 18:41:51 GMT")
 (address "127.0.0.1")
 (get "/")
 (headers
  ("POST" "/" "HTTP/1.1")
  ("Host" "localhost:8080")
  ("Connection" "close")
  ("Authorization" "Bearer eyJh…$
  ("Content" ""))
--8<---------------cut here---------------end--------------->8---

Now, with the correct header, it works:

--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> ,use(web client)
scheme@(guix-user)> (http-request 
"https://archive.softwareheritage.org/api/1/stat/counters/"; #:method 'POST 
#:headers `((authorization . (Bearer ,token))))
$2 = #<<response> version: (1 . 1) code: 405 reason-phrase: "Method Not 
Allowed" headers: ((date . #<date nanosecond: 0 second: 2 minute: 59 hour: 18 
day: 14 month: 10 year: 2021 zone-offset: 0>) (server . "gunicorn/19.9.0") 
(content-type application/json) (vary accept cookie) (allow GET OPTIONS HEAD 
OPTIONS) (x-ratelimit-limit . "1200") (x-ratelimit-remaining . "137") 
(x-ratelimit-reset . "1634237954") (x-frame-options . "SAMEORIGIN") 
(content-length . 72) (via "1.1 archive.softwareheritage.org") (x-varnish .

(strict-transport-security . "max-age=15768000;") (connection close)) port: 
#<closed: file 7f624e3f51c0>>
$4 = #vu8(123 34 101 120 99 101 112 116 105 111 110 34 58 34 77 101 116 104 111

108 111 119 101 100 46 34 125)
--8<---------------cut here---------------end--------------->8---
