    // This example does the following:

    // curl -X GET https://yourInstance.salesforce.com/services/oauth2/userinfo \
    //      -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

    // Use the following online tool to generate HTTP code from a CURL command
    // Convert a cURL Command to HTTP Source Code

    // This example assumes the OAuth2 access token was previously fetched 
    // and saved to a file.  See Get SalesForce OAuth2 Access Token via Authorization Flow
