Question is how to get the Static Resource's URL in Apex, so below is the function which will return the relative URL (also supports namespace-resources)
Use this in debug logs to verify :
*Please change the "StaticResourceName" with your Static resource name in above line
public class StaticResourceURL
{
//Pass the resource name
public static String GetResourceURL(String resourceName)
{
//Fetching the resource
List resourceList = [SELECT Name, NamespacePrefix, SystemModStamp FROM StaticResource WHERE Name = :resourceName];
//Checking if the result is returned or not
if(resourceList.size() == 1)
{
//Getting namespace
String namespace = resourceList[0].NamespacePrefix;
//Resource URL
return '/resource/' + resourceList[0].SystemModStamp.getTime() + '/' + (namespace != null && namespace != '' ? namespace + '__' : '') + resourceName;
}
else return '';
}
}
Use this in debug logs to verify :
System.debug(':::: ' + StaticResourceURL.GetResourceURL('StaticResourceName')) ;
*Please change the "StaticResourceName" with your Static resource name in above line
Good post Ankit!!!

ReplyDeleteGood stuff. "List resourceList" should be "List <StaticResource> resourceList" though..
ReplyDeleteHi Ankit,
ReplyDeleteReally a great post! Kinda exactly what I was looking for. However, I am stuck with one strange thing and was hoping you or someone else had some solutions.
Here is my code which is invoking the GetResourceURL(), where $1 represents the resource_name in the following code.
{!URLFOR($Resource.resource_name,'images/image_name.jpg')}
CODE
-----
String body1 = body.replaceAll('\\{!URLFOR\\(\\$Resource\\.(.+?),\\\'(.+?)\\\'\\)\\}',GetResourceURL('$1') + '/$2');
If I print the value for $1 within GetResourceURL it prints it, but the SOQL query doesn't return any records :( whereas if instead of $1 if I pass the same hard coded string value it returns the correct result set ...
Any idea on what I should try?
Complete Code
-------------
public String getBody() {
String body = xec.Content__c;
// THIS DOESN'T WORK
String body1 = body.replaceAll('\\{!URLFOR\\(\\$Resource\\.(.+?),\\\'(.+?)\\\'\\)\\}',GetResourceURL('$1') + '/$2');
// THIS WORKS
String body1 = body.replaceAll('\\{!URLFOR\\(\\$Resource\\.(.+?),\\\'(.+?)\\\'\\)\\}',GetResourceURL('resource_name') + '/$2');
return body1;
}
public String GetResourceURL(String rn)
{
//Fetching the resource
List resourceList = [SELECT Name, NamespacePrefix, SystemModStamp FROM StaticResource WHERE Name = :rn];
//Checking if the result is returned or not
if(resourceList.size() == 1)
{
//Getting namespace
String namespace = resourceList[0].NamespacePrefix;
//Resource URL
return '/resource/' + resourceList[0].SystemModStamp.getTime() + '/' + (namespace != null && namespace != '' ? namespace + '__' : '') + rn;
}
else return '';
}
Excellent Work. This is really an amazing website. I like that
