azure - 使用 Flask 应用程序处理 Azure 中的端口

问题描述

我对 Web 开发非常陌生，目前正在尝试在 Microsoft Azure 上部署 Flask 应用程序。部署成功，但网站加载很长时间然后崩溃......我在应用程序日志中得到的错误如下：

我错过了什么？

在我的 main.py 文件中，我设置了 app.run(debug=True); 所以没有指定端口和主机，可以吗？在我设置的 Cloud Shell 中：

az webapp config appsettings set --resource-group <resource-group-name> --name <app-name> --settings WEBSITES_PORT=8000

有谁知道问题出在哪里？

一切顺利，

解决方案

在 Azure App Service (Web App) 上托管您的 webapp，您只能使用端口 80 和 443。如果您需要自定义端口，则需要使用 Azure 虚拟机来托管您的应用程序
