Question

尝试部署节点应用程序时，我收到以下Heroku日志。我无法找出原因。我猜想这与我的index.html文件中的收藏夹链接有关吗？

一次分配给您的IP地址都会经常更改。不要特别地绑定它们。

相反，绑定到所有可用的 IP地址，该地址通常由0.0.0.0表示或根本不提供IP地址。确保还使用Heroku通过PORT环境变量指定的端口。

假设您正在使用Express，something like this should work：

const express = require('express')
const PORT = process.env.PORT || 5000  # Fall back to port 5000 if process.env.PORT is not set

express()
  .listen(PORT, () => console.log(`Listening on ${ PORT }`))
