|
|
260 | |
|
|
261 | Sends a generic request of type C<$type> to the server. When the server |
|
|
262 | responds, the API object and the response arguments (without the success |
|
|
263 | status) are passed to the callback, which is the last argument to this |
|
|
264 | method. |
|
|
265 | |
|
|
266 | If the request fails, then a fatal error will be raised. If you want to |
|
|
267 | handle failures gracefully, you need to use C<< ->req_failok >> instead. |
|
|
268 | |
|
|
269 | The available requests are documented in the Porttracker API |
|
|
270 | documentation (a copy of which is included in this module as |
|
|
271 | L<AnyEvent::Porttracker::protocol>. |
|
|
272 | |
|
|
273 | It is permissible to call this (or any other request function) at any |
|
|
274 | time, even before the connection has been established - the API object |
|
|
275 | always waits until after login before it actually sends the requests, and |
|
|
276 | queues them until then. |
|
|
277 | |
|
|
278 | Example: ping the porttracker server. |
|
|
279 | |
|
|
280 | $api->req ("ping", sub { |
|
|
281 | my ($api, $ok, $timestamp, $pid) = @_; |
|
|
282 | ... |
|
|
283 | }); |
|
|
284 | |
|
|
285 | Example: determine the product ID. |
|
|
286 | |
|
|
287 | $api->req (product_id => sub { |
|
|
288 | my ($api, $ok, $branding, $product_id) = @_; |
|
|
289 | ... |
|
|
290 | }); |
|
|
291 | |
|
|
292 | Example: set a new license. |
|
|
293 | |
|
|
294 | $api->req (set_license => $LICENSE_STRING, sub { |
|
|
295 | my ($api, $ok) = @_; |
