164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
The object of this class behaves as PSGI application (subroutine reference). |
166
|
|
|
|
|
|
|
This is for OAuth 2.0 token-endpoint. |
167
|
|
|
|
|
|
|
|
168
|
|
|
|
|
|
|
At first you have to make your custom class inheriting L, |
169
|
|
|
|
|
|
|
and setup PSGI file with it. |
