need to get desired data from string using batch

Question

i need to extract only URL and app id in the given string and saved in variables

url:{ \"url\":\"ad.ifwcash.com/www/delivery/afr.php?zoneid=127&cb=201

Answer 1

this works if there's an url.txt file in same directory with content: {"url":{ "url":"ad.ifwcash.com/www/delivery/afr.php?zoneid=127&cb=2015738640", "app":61}} Eventually you'll need to change name/location of the file on the third line (save the file bellow with .bat extension):

@echo off

setlocal enableDelayedExpansion

set "jsonFile=.\url.txt"
set counter=1



for /f %%# in ('echo %jsonFile%^|mshta.exe "%~f0"') do (
  set "variable_!counter!=%%#"
  set /a counter=counter+1
)

set variable_

echo #############################
echo ###  more batch code here ###
echo #############################


exit /b

<HTA:Application
   ShowInTaskbar = no
   WindowsState=Minimize
   SysMenu=No
   ShowInTaskbar=No
   Caption=No
   Border=Thin
>
<meta http-equiv="x-ua-compatible" content="ie=edge" />
<script language="javascript" type="text/javascript">
    window.visible=false;
    window.resizeTo(1,1);

   var fso= new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(1);
   var fso2= new ActiveXObject('Scripting.FileSystemObject').GetStandardStream(0);
   var json=fso2.ReadLine();

   var fso3=new ActiveXObject("Scripting.FileSystemObject");

   var file = fso3.OpenTextFile(json, 1);

    var strText = file.ReadAll();
    file.Close();

   var obj = JSON.parse(strText)

   fso.Write(obj.url.url + "\r\n" + obj.url.app + "\r\n");
   window.close();
</script>

Answer 2

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.
