我正在开发Azure边缘模块，在那里我创建了一个自定义模块，该模块实际上在边缘运行时内接收到了来自另一个模块的消息。
我的要求是通过HTTPpost方法将数据发送到外部网关(例如thingsboard(。在docker文件中，暴露80端口并与本地机器80端口绑定。
问题是，每当我试图使用HTTP-post方法将消息从自定义模块发送到外部网关(thingsboard(时，都会得到HTTP500的错误。
如果我直接运行容器(而不是在边缘运行时下(，工作正常。
由于我在容器中的代码想要通过互联网向外部世界(外部设备或网关(发送消息。我正在向thingsboard发送消息(http://demo.thingsboard.io/api/v1/camera/telemetry)。

我应该如何解决这个问题？如何将消息发送到外部网关
谢谢。
默认情况下，您在Azure IoT Edge中的模块将能够访问互联网，除非配置发生了更改，或者有防火墙限制您访问事物。io要验证您的模块是否可以访问该URL，您可以尝试以下操作：
docker run -i --rm -p 80:80 --network="azure-iot-edge" alpine ping thingsboard.io
这将在与模块相同的Docker网络上运行一个容器，并查看您是否可以解析URL。
您提到了HTTP状态代码500，它表示服务器(来自Thingsboard(对您的请求有问题。因为你提到，如果你只是手动运行容器，这是有效的，这可能是因为当你在Azure IoT Edge运行时运行模块时，你的负载不同。一个简单的方法是使用日志记录来检查在每个场景中发送给Thingsboard的内容。
注意：在你的问题中，你说
在docker文件中，暴露80端口并与本地机器80端口绑定
只有当您希望模块通过端口80接受传入的请求时，才需要这样做。对于传出请求(例如发送到Thingsboard的消息(，不需要这样做。
