solved URL decoding via JavaScript in Alfred

[AGBear]

Hi everyone,

 

I have to work with Office 365 Advanced Threat Protection 'safelinks' all day long: these are URLs checked for phishing and other cybersecurity issues, then converted into a unique format.

 

https://aus01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.google.com%2F&data=04|lots of parameters and personally identifiable information that isn't important for this purpose|

 

 

There are many tools available to decode these URLs - like https://o365atp.com/ .

 

Rather than pasting URLs into that website every time, I want to use Alfred to process the Office URLs and return the 'real' URL to the clipboard.

 

Digging into the source of that website, the underlying Javascript is pretty straightforward. However my knowledge of scripting is limited to basic bash (and some Perl ten years ago) so I don't know how to convert that link variable into a query passed from Alfred. Can anyone help with this? Thanks in advance!

 

function decode_url()
{
    setTimeout("generate_decode_url()", 20);
}

function generate_decode_url()
{
    var link = document.getElementById("safelink").value;
    var url_parts = link.split("?")[1];
    var params = url_parts.split("&");
    var target_url = "Error:  couldn't find target URL.";
    for(n=0;n<params.length;n++)
    {
        namval = params[n].split("=");
        if(namval[0]=="url") target_url = namval[1];
    }
    
    decode_url = decodeURIComponent(target_url);
    document.getElementById("target_url").value = decode_url;
    
}

function clear()
{
    location.reload();
}

clarified URL format

If I’m understanding correctly, what you want is a Run Script Action with language /usr/bin/osascript (JavaScript) and code:

function run(argv) {
  return decodeURIComponent(argv[0].split("?url=")[1].split('&')[0])
}

That will take whatever argument you passed early (e.g. from a Keyword Input), transform it, and output it to the next Alfred object.

Wow, that works perfectly! Thanks so much for your help!
