¿Cómo escribir un AppleScript que descargue el estado de la red Wi-Fi desde la interfaz web del enrutador?

Sobre la base de las discusiones, esto debería manejar el alcance original de la pregunta.

Nota: Este es un ejemplo de código y no contiene mucho, si lo hay, manejo de errores. Te lo dejaré ya que esto es solo una parte del guión general, una vez que hayas juntado todas las demás piezas.

--  # 
--  #   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;"

                    tell current application

                        --  #   Process the 'rawWiFi24HTML' and 'rawWiFi5HTML' variables.
                        --  #   Setup some temporary files to handle the processing.

                        set rawHTML to "/tmp/rawHTML.tmp"
                        set rawIP to "/tmp/rawIP.tmp"

                        --  #   Combine the value of  the'rawWiFi24HTML' and 'rawWiFi5HTML' variables into the 'rawHTML' temporary file.

                        do shell script "echo " & quoted form of rawWiFi24HTML & " > " & rawHTML & "; echo " & quoted form of rawWiFi5HTML & " >> " & rawHTML

                        --  # Process the 'rawHTML' into the 'rawIP' and 'rawDBM' temporary files.
                        --  # These files will contain comma delimited content of the targeted info.

                        do shell script "grep 'IP:' " & rawHTML & " | sed -e 's:</span>.*$::g' -e 's:^.*>::g' | tr '\12' ',' > " & rawIP & "; grep 'device.parsedSignalStrength' " & rawHTML & " | sed -e 's: dBM.*$::g' -e 's:^.*\"::g' | tr '\12' ',' > " & rawDBM

                        -- 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
    end if
end tell

--  # Handler used to create a list from a CSV file.

on makeListFromCSVFile(thisFile)
    set thisFilesContents to (read thisFile)
    set AppleScript's text item delimiters to {","}
    set thisList to items 1 thru -2 of text items of thisFilesContents as list

Tengo que decir que, en general, se supone que uno no debe analizar HTML con herramientas como grep y sed , sin embargo, para ciertas páginas, como en este caso de uso, es bastante seguro hacerlo. Aunque, si se rompe, no es difícil de arreglar.

1. Vaya a la página web en el navegador Chrome.
2. Abra el navegador de JavaScript de las herramientas de desarrollo.
3. Pega esto en la consola y pulsa enter:

$('script').each(function(){
    console.log($(this).html())
});
