azure应用程序服务容器（容器名称）未响应端口8080上的HTTP pings

Question

我创建了一个非常简单的Discord机器人，并试图将其托管在Azure上。当我在本地运行它时，它工作正常。当我部署它时，它可以正常工作一段时间，然后崩溃并重新启动。

我得到

我没有设置docker，所以我猜azure正在为我做这件事。

我的包裹看起来像这样

{
  "name": "my-bot",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "start": "node stonksbot.js"
  },
  "dependencies": {
    "discord.js": "^11.6.3"
  },
  "devDependencies": {}
}

我的代码如下所示。

const Discord = require('discord.js');
const client = new Discord.Client();


client.login(my token);

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('message', msg => {

  // do something
});

有人知道解决方案吗？

您需要让您的应用在指定的端口上响应来自Azure App Service的ping。

此处为示例：https://github.com/Azure-Samples/nodejs-docs-hello-world/blob/master/index.js

您还需要将环境变量WEBSITES_PORT设置为端口的值。

如果不响应ping，Azure会认为该应用程序已关闭并尝试重新启动它。
