專用輸出IP位址和VPN的HTTP/HTTPS連線

HTTP/HTTPS連線會自動使用專用輸出IP位址或VPN從AEM as a Cloud Service代理出去,而且不需要任何特殊的portForwards規則。

進階網路支援

下列進階網路選項支援下列程式碼範例。

在執行本教學課程之前,請確定已設定專用輸出IP位址或VPN進階網路設定。

CAUTION
此程式碼範例僅適用於專用輸出IP位址VPN。 針對彈性連線埠輸出🔗的非標準連線埠上的HTTP/HTTPS連線,有類似但不同的程式碼範例可用。

程式碼範例

此Java™程式碼範例屬於OSGi服務,可在AEM as a Cloud Service中執行,與8080上的外部網頁伺服器建立HTTP連線。 HTTPS (或HTTP)連線會自動以代理方式從AEM as a Cloud Service出去,不需要特別開發。

NOTE
建議使用Java™ 11 HTTP API進行來自AEM的HTTP/HTTPS呼叫。
