node.js - 将 Express 应用程序部署到 Azure 应用程序服务未响应端口 : 8080 上的 HTTP ping

Question

我尝试将我的 NestJs 应用程序(使用快速适配器)部署到 Azure 应用服务。在 docker 日志中我收到此错误:

我用这一行绑定(bind)了express服务器

 const port = Number(process.env.PORT) || 8080;

我用谷歌搜索了一段时间来寻找解决方案，但没有任何帮助。以下是我现在尝试使用的步骤。

• 将 WEBSITES_CONTAINER_START_TIME_LIMIT 增加到 1800
• 将 WEBSITES_PORT 和 PORT 设置为 80
• 重新创建并重新部署应用

有人知道为什么这个问题仍然出现吗？我的应用程序列在正确的端口上，并在 / 下返回 200 Http 状态，并且还实现了 400 错误处理程序(我了解到此云也是一个问题)。

你可能使用Sentry吗？我们遇到了类似的问题，并且能够将其追溯到 Sentry。在没有 Sentry 和默认配置的情况下尝试一下。
