* This class is used to make proxied service requests via the HTTP GET method.

|
34 |
*
|
|
|
35 |
* try {

|
36 |
* $service = phpCAS::getProxiedService(PHPCAS_PROXIED_SERVICE_HTTP_GET);

|
|
|
39 |
* if ($service->getResponseStatusCode() == 200)

|
|
40 |
* return $service->getResponseBody();
|
|
|
41 |
* else

|
|

|
|
|
47 |
* return "Your login has timed out. You need to log in again.";
|
|
|
48 |
* else
|
|
|
49 |
* // Other proxy ticket errors are from bad request format
|
|
|
50 |
* // (shouldn't happen) or CAS server failure (unlikely)
|
|
|
51 |
* // so lets just stop if we hit those.

* throw $e;

|
54 |
* // Something prevented the service request from being sent or received.
|
|
|
55 |
* // We didn't even get a valid error response (404, 500, etc), so this
|
|
|
56 |
* // might be caused by a network error or a DNS resolution failure.
