// 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
