diff changeset
83 C<$ENV{PATH_INFO}> используется как путь к нужному ресурсу у которого будет вызван метод указанный в запросе.

87 =head2 Resource model
sergey
parents: 212
diff changeset
88
sergey
parents: 212
diff changeset
89 Ресурсы имеют иерархическую структуру, аналогичную файлам и каталогам, которая описывается контрактом, также
sergey
parents: 212
diff changeset
90 контрак описывает то, как должны обрабатываться методы C<HTTP> запроса, такие как C<GET> и C<POST>.
sergey
parents: 212
diff changeset
91
sergey
parents: 212
diff changeset
92 За корректность реализации данных методов отвечает разработчик.
sergey
parents: 212
diff changeset
93
sergey
parents: 212
diff changeset
94 Каждый ресурс представляет собой коллкецию вложенных ресурсов, путь указанный в C<HTTP> запросе разбивается на
sergey
parents: 212
diff changeset
95 части, затем каждый сегмент последовательно используется для поиска дочернего ресурса. При обработки
sergey
parents: 212
diff changeset
96 первого сегмента используется корневой ресурс. Корневой ресурс должен существовать всегда.
