public static String getATFromParameter(javax.servlet.http.HttpServletRequest request)
```
    This gets the tokens from the authorization header. There are several types and it is possible to have several values passed in, so this returns an array of string rather than a single value. A downside with passing along several values this way is there is no way to disambiguate them, e.g. a client id from a client secret. If there is no authorization header or there are no tokens of the stated type, the returned value is an empty list.
    
    Parameters:
    
    request -
    
    Returns:
  - getIDFromParameters
```
