Get Site URL from apex

Question

Is there a way to get the URL of a salesforce site from apex

I need this to send the url in an email message, so the apex is run outside of the site context. I basically want to expose a link to my salesforce site in an email message. But so far I haven't found a way to do that

I would prefer not hard coding the url in apex

Answer 1

This used to work. I didn't tested it recently, try it out.

Site s = [SELECT s.Subdomain FROM Site s LIMIT 1 ];
String urlCode = String.valueof(URL.getSalesforceBaseUrl().toExternalForm());
String [] cuts = urlCode.split('[.]');
urlCode = '';
for(Integer i = 1; i < cuts.size(); i++){
    if(!cuts[i].contains('visual')){
        urlCode += cuts[i] + '.';
    }
}     
urlCode = urlCode.substring(0, urlCode.length()-1);  
urlCode = 'https://'+s.Subdomain+'.'+urlCode+'/yourpage;

If you are looking to associate to a single record, you will need to use the PageReference class. Specifically:

ApexPages.currentPage().getHeaders().get('Host');

and

ApexPages.currentPage().getHeaders().getUrl();

To piece that together you would use the following:

String url = 'https://' + ApexPages.currentPage().getHeaders().get('Host') + ApexPages.currentPage().getHeaders().getUrl();

If you are looking to link to a specific object, you just need the host and the ID of that object. Say you want to link to an account for instance and the account you have is referenced by the acc variable:

String url = 'https://' + ApexPages.currentPage().getHeaders().get('Host') + '/' + acc.Id;

Please refer the below link:

http://boards.developerforce.com/t5/Apex-Code-Development/Get-Current-Page-URL-in-Apex-Class-Full-amp-Exact-URL/td-p/134623

seems you might need to make use of

apexpages.currentpage().getURL() and apexpages.currentpages().getHeaders().get('HOST')

This doesn't seem to be possible from apex, I ended up trying the different ways described above, and decided to go with a Custom Setting. I added the Custom Setting Site URL which needs to be filled in every time when the app gets configured.
