Question

第一次使用Heroko。按照步骤，我的构建成功，但当我转到URL时，我收到了一个应用程序错误。我查看了日志，但我不确定发生了什么，下面是我的日志列表

Answer 1

您在Procfile中定义了什么？现在，它似乎是这样的：

web: node server.js

Procfile告诉Heroku如何运行您的应用程序。您显示的日志表明您尝试在端口8088上运行节点服务器 - 这可能是问题所在。

Heroku不允许您在所需的任何端口上运行服务器 - 相反，它会动态地告诉您在应用程序启动时运行服务器的端口。它通过使用名为PORT的环境变量来实现这一点。

您需要做的是修改server.js代码，以便在process.env.PORT上启动服务器。

这是一个例子（在express.js中）：

var express = require('express');

var app = express();

app.listen(process.env.PORT);

这将通过自动绑定到正确的端口成功启动Heroku上的节点服务器。

希望有所帮助！
