Simple urlDecode() example

Shows how it takes an input of: %21 and returns: !

urlDecode("%21")

Expected Result: !

Basic urlDecode() usage

In this example we demonstrate taking a URL encoded message passed on the request context and displaying it decoded.

if( len( rc.msg ) ) {
	writeOutput( encodeForHTML( urlDecode( rc.msg ) ) );
}

urlDecode() in obfuscation

In this example we demonstrate url encoding a password before it is encrypted, and then decoding it after it is decrypted.

pwd = urlEncodedFormat( '$18$f^$XlTe41' );
writeOutput( pwd & ' : ' );
pwd = encrypt( pwd, '7Z8of/gKWpqsx/v6O5yHRKanrXsp93B4xIHV97zf88Q=', 'BLOWFISH/CBC/PKCS5Padding', 'HEX' );
writeOutput( pwd & ' : ' );
decpwd = decrypt( pwd, '7Z8of/gKWpqsx/v6O5yHRKanrXsp93B4xIHV97zf88Q=', 'BLOWFISH/CBC/PKCS5Padding', 'HEX' );
writeOutput( decpwd & ' : ' );
decpwd = urlDecode( decpwd );
writeOutput( decpwd );

Expected Result: %2418%24f%5E%24XlTe41 : : %2418%24f%5E%24XlTe41 : $18$f^$XlTe41

urlDecode() usage as a member function

In this example we demonstrate taking a URL encoded message passed on the request context and displaying it decoded using the urlDecode() member function.

if( len( rc.msg ) ) {
	writeOutput( encodeForHTML( rc.msg.urlDecode() ) );
}
