In Summer 17 Release (v.40) Salesforce provided a way to retrieve URL for item inside Static Resource within Apex which was very required feature and which was asked many times (like in this question).

I have a question, is there any viable way to get URL in Apex for standard salesforce SLDS asset?

In Visualforce it is possible to use something like {!URLFOR($Asset.SLDS, 'assets/images/profile_avatar_96.png')} but I haven't found any way to do this in Apex.

It is not possible to query that object since this is not Asset or ContentAsset object instance.

If only I knew the URL I could use it to fetch the content like new PageReference(url_file_ref).getContent().toString();

I could achieve this if I download SLDS as resource and upload it as static resource but since it is provided like some kind of assets I would like to avoid this.

  • Have you tried /sfsites/c/file-asset/{name}? In Communities I used {communityName}/s/sfsites/c/file-asset/{name} Commented Dec 18, 2019 at 14:14
  • @ytiq I am using PageReference sprite = new PageReference('/_slds/icons/standard-sprite/svg/symbols.svg'); - however, this might be fragile if Salesforce moves those files Commented Dec 18, 2019 at 14:15
  • then try uploading it asset and then using PageReference sprite = new PageReference('/sfsites/c/file-asset/symbols'); Commented Dec 18, 2019 at 14:23
  • I don't want to upload anything since it is already available in Visualforce Commented Dec 18, 2019 at 14:59

I have found the following way to achieve this. I have created a Visualforce page Urlfor

<apex:page controller="UrlforController" showHeader="false" sidebar="false" standardStylesheets="false"> <apex:form > <apex:dynamicComponent componentValue="{!c}"/> </apex:form> </apex:page>

and a class UrlforController

public inherited sharing class UrlforController { private static final String START = 'UrlforStart('; private static final String FINISH = ')UrlforFinish'; public UrlforController() { text = ApexPages.currentPage().getParameters().get('text'); System.debug(LoggingLevel.ERROR, 'text ' + text); } public String text { get; set; } public Component.Apex.OutputText getC() { Component.Apex.OutputText outputText = new Component.Apex.OutputText(); System.debug(LoggingLevel.ERROR, 'text ' + text); outputText.expressions.value = START + text + FINISH; System.debug(LoggingLevel.ERROR, 'outputText.value ' + outputText.value); return outputText; } public static String get(String expression) { PageReference r = Page.Urlfor; r.getParameters().put('text', expression); System.debug(LoggingLevel.ERROR, 'r.getContent().toString() ' + r.getContent().toString().substringBetween(START, FINISH)); } }

Then I use UrlforController.get('{!URLFOR($Asset.SLDS,\'/assets/icons/utility-sprite/svg/symbols.svg#announcement\')}') to get the actual URL /_slds/icons/utility-sprite/svg/symbols.svg#announcement
