300
|
|
|
* This function verifies that all of the various OIDC parameters are |
|
301
|
|
|
* set in the PHP session. First, the function checks if an OIDC |
|
302
|
|
|
* client has passed appropriate parameters to the authorization |
|
303
|
|
|
* endpoint. If so, we call the 'real' OA4MP OIDC authorization |
|
304
|
|
|
* endpoint and let it verify the client parameters. Upon successful |
|
305
|
|
|
* return, we call the getClient() function of the dbService to get |
|
306
|
|
|
* the OIDC client name and homepage for display to the user. All |
|
307
|
|
|
* client parameters (including the ones passed in) are saved to the |
|
308
|
|
|
* 'clientparams' PHP session variable, which is encoded as a JSON |
|
309
|
|
|
* token to preserve arrays. If there are any errors, false is returned |
|
310
|
|
|
* and an email is sent. In some cases the session variable |
|
311
|
|
|
* 'client_error_msg' is set so it can be displayed by the |
|
312
|
|
|
* printOIDCErrorPage() function. |
|
313
|
|
|
* |
|
314
|
|
|
* @return bool True if the various parameters related to the OIDC |
|
315
