* HTTP Bearer authentication utility.
|

|
|
*
|
||
|
|
* This class helps you setup bearer auth. The process is fairly simple:
|
||
|
|
*
|
||
|
|
* 1. Instantiate the class.
|
||
|
|
* 2. Call getToken (this will return null or a token as string)
|
||
|
|
* 3. If you didn't get a valid token, call 'requireLogin'
