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。
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。
无高级联网 | 灵活端口出口 | 专用出口IP地址 | 虚拟专用网络 |
---|---|---|---|
✘ | ✘ | ✔ | ✔ |
此代码示例仅用于 专用出口IP地址 和 VPN. 有一个相似但不同的代码示例可用于 非标准端口上的HTTP/HTTPS连接,用于灵活端口出口.
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。
建议使用 Java™ 11 HTTP API 用于从AEM进行HTTP/HTTPS调用。
