专用出口IP地址和VPN的HTTP/HTTPS连接

HTTP/HTTPS连接会自动用专用出口IP地址或VPN从AEMas a Cloud Service代理，并且它们不需要任何特殊的 portForwards 规则。

高级联网支持

以下高级联网选项支持以下代码示例。

确保 专用出口IP地址或VPN 在执行本教程之前，已设置高级联网配置。

代码示例

此Java™代码示例是一个可在AEMas a Cloud Service中运行的OSGi服务，该服务与8080上的外部Web服务器建立HTTP连接。 HTTPS（或HTTP）连接会自动通过AEMas a Cloud Service进行代理，而无需特殊开发。
