Creating the Controller

Now that you have configured ScreenSteps Live you need to create a controller and a page in Salesforce.com. We will begin by creating the Controller for the Visualforce page.

Navigate to your Salesforce.com Setup Area

Navigate to Apex Classes Page

From the menu, expand Develop and click on Apex Classes.

Create a New Class

Click on the New button to create a new class.

Paste In ScreenStepsLiveRemoteLoginController Code

In the code field (1) paste the code that appears below. Make sure to replace the string INSERT_REMOTE_AUTH_TOKEN_HERE in the code with the remote authentication token you copied in the previous lesson.

After pasting in the code and inserting your token, click the Save button (2).

public class ScreenStepsLiveRemoteLoginController {
    public string md5String {get;set;}
    private string ssliveToken = 'INSERT_REMOTE_AUTH_TOKEN_HERE';
    
    public ScreenStepsLiveRemoteLoginController () {
        // UserInfo does not expost the email address
        String theUserName = UserInfo.getUserName();
        User activeUser = [Select Email From User where Username = : theUserName limit 1];
        String theEmail = activeUser.Email;
        String theOrgName = ''; //UserInfo.getOrganizationName(); (not available in apex page)

        String theReturnToURL = ApexPages.CurrentPage().getParameters().get('return_to_url');
        String theTimeStamp = ApexPages.CurrentPage().getParameters().get('timestamp');
        
        String theStringToHash = UserInfo.getFirstName() + UserInfo.getLastName() + 
        theEmail + UserInfo.getUserId() + theOrgName + 
        this.ssliveToken + theTimeStamp;
        
        Blob keyblob = Blob.valueof(theStringToHash);
        Blob key = Crypto.generateDigest('MD5',keyblob);
        md5String = encodingUtil.convertToHex(key);
    }

    static testMethod void testTheController() {
        ScreenStepsLiveRemoteLoginController login = new ScreenStepsLiveRemoteLoginController();
    }
}
