Encoding Your Data
You can encode and decode URLs and convert strings to hexadecimal
format by using the methods provided by the EncodingUtil class.
This example shows how to URL encode a timestamp value in UTF-8 by calling urlEncode.
DateTime d = System.now();
String timestamp = ''+ d.year() + '-' +
d.month() + '-' +
d.day() + '\'T\'' +
d.hour() + ':' +
d.minute() + ':' +
d.second() + '.' +
d.millisecond() + '\'Z\'';
System.debug(timestamp);
String urlEncodedTimestamp = EncodingUtil.urlEncode(timestamp, 'UTF-8');
System.debug(urlEncodedTimestamp);
This next example shows how to use convertToHex to compute a client response for HTTP Digest Authentication (RFC2617).
@isTest
private class SampleTest {
static testmethod void testConvertToHex() {
String myData = 'A Test String';
Blob hash = Crypto.generateDigest('SHA1',Blob.valueOf(myData));
String hexDigest = EncodingUtil.convertToHex(hash);
System.debug(hexDigest);
}
}
