InetGet with unknown file name

Recommended Posts

i want to download the latest version of firefox msi installer using an url like

https://download.mozilla.org/?product=firefox-msi-latest-ssl&os=win64&lang=de

in this case the filename is unknown before download and i also do not want to use a static name like 'firefox-latest' or similar. a web browser is able to read the correct filename before downloading it so maybe autoit is able to do that too so i can set a variable before the actual download starts?

Hmm, you don't want this "latest" expression however it is present everywhere  :huh2:
If you want to know the version number of this latest one you are downloading, just Inetread the page and get it

$s = BinaryToString(InetRead("https://www.mozilla.org/de/firefox/"))
$version = StringRegExpReplace($s, '(?s).*?data-latest-firefox="([^"]+).*', "$1") ; latest
$file = "Firefox Setup " & $version & ".msi"
$url = "https://download-installer.cdn.mozilla.net/pub/firefox/releases/" & $version & "/win64/de/" & $file
InetGet($url, @scriptdir & "\" & $file)

thank you. nice solution!

theoretically the filename must come together with the download. if you put an url like

https://download.mozilla.org/?product=firefox-msi-latest-ssl&os=win64&lang=de

into your browser the next thing that happens is that you are asked if/where you want to save a file named

Firefox Setup 68.0.msi

on your computer. thats why i thought this filename (sent by the site as a result of the query string) could be read out somehow.

[for downloading the url

https://ftp.mozilla.org/pub/firefox/releases/68.0/win64/de/

might be a good choice too]

Yes it does. The location of the download (which contains the filename) is returned in the response headers of the page, along with the content-type, the file size, etc. To make the script have the same behaviour than the browser there are 2 actions to perform
