need to get desired data from string using batch

问题

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=2015738640", "app":61}

final result like

variable_1 : ad.ifwcash.com/www/delivery/afr.php?zoneid=127&cb=2015738640

variable_2 : 61

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.

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

   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>
