Comment écrire un AppleScript qui télécharge le statut du réseau Wi-Fi à partir de l'interface web du routeur ?

Sur la base des discussions qui ont eu lieu, cela devrait répondre à la portée initiale de la question.

Note : Ceci est un exemple code et ne contient pas beaucoup, voire pas du tout, de gestion des erreurs. Je vous laisse faire puisque ce n'est qu'une partie du script global, une fois que vous avez assemblé tous les autres morceaux.

--  # 
--  #   Get the target information from theTargetURL in Google Chrome.
--  #   
--  #   Do this in the background, so get the 'tab id' and 'window id' of
--  #   the target URL ('theTargetURL') if it exists, and process accordingly. 

set theTargetURL to "http://192.168.1.1/0.1/gui/#/"

tell application "Google Chrome"
    if running then
        set theWindowList to every window
        repeat with thisWindow in theWindowList
            set theTabList to every tab of thisWindow
            repeat with thisTab in theTabList
                if theTargetURL is equal to (URL of thisTab as string) then

                    --  #   Get the targeted content of the web page which contains the information.
                    --  #   Note that document.getElementById(elementID) can only query one
                    --  #   element at a time, therefore call it twice, once with each elementID.

                    set rawWiFi24HTML to thisTab execute javascript "document.getElementById('wifi-24').innerHTML;"
                    set rawWiFi5HTML to thisTab execute javascript "document.getElementById('wifi-5').innerHTML;"

                        --  # These files will contain comma delimited content of the targeted info.

                        -- Process 'rawIP' and 'rawDBM' temporary files into 'theIPAddressList' and 'theSignalStrengthList' lists.

                        set theIPAddressList to my makeListFromCSVFile(rawIP)
                        set theSignalStrengthList to my makeListFromCSVFile(rawDBM)

                        --  #   Clean up, remove temporary files.

                        do shell script "rm /tmp/raw*.tmp"

                    end tell

                end if
            end repeat
        end repeat

Je dois dire qu'en général, on n'est pas censé analyser le HTML avec des outils tels que grep y sed Cependant, pour certaines pages, comme dans ce cas d'utilisation, il est assez sûr de le faire. En revanche, s'il se casse, il n'est pas difficile à réparer.
