Answer 1

Here's another hybrid solution using JScript. (Still save it with a .bat extension.)

@if (@CodeSection == @Batch) @then

@echo off
setlocal

set "JSONfile=test.json"

for /f "delims=" %%I in ('cscript /nologo /e:JScript "%~f0" "%JSONfile%"') do set "%%~I"

setlocal enabledelayedexpansion
echo URL: !url!
echo App: !app!
endlocal

goto :EOF

@end // end batch / begin JScript chimera

var fso = WSH.CreateObject('scripting.filesystemobject'),
    JSONfile = fso.OpenTextFile(WSH.Arguments(0), 1);

eval('obj = {' + JSONfile.ReadAll() + '}');
JSONfile.Close();

function walk(tree) {
    for (var i in tree) {
        if (typeof tree[i] === 'object') walk(tree[i]);
        else WSH.Echo(i + '=' + tree[i]);
    }
}

walk(obj);

Output:

URL: ad.ifwcash.com/www/delivery/afr.php?zoneid=127&cb=2015738640
App: 61

Delayed expansion was used to prevent the & in the URL from being evaluated.

See this big fat warning if you don't control the generation of the JSON.
