如何找出heroku有什么問題？

Question

我創建了一個非常簡單的 nodejs 應用程序，鏈接在這里https://bitbucket.org/danclaudiu95/mongo-nodejs-0.git

我只有一個 index.js 文件

router.get('/', (req, res) => {
    res.send('Hello World')
})

並提交並推送更改到heroku，該應用程序在此處https://git.heroku.com/nodejs-mongo-cc.git ，它告訴我“不允許使用方法”，此處為https://nodejs-mongo-cc。 herokuapp.com/是tels應用程序錯誤 我在運行 heroku logs 時收到此日志 --tail 我有此日志

任何人都可以幫助我嗎？

Answer 1

確保遵循 Heroku 網站中的 node.js 指南。 您可以在此處找到 - 使用 Node.js 開始使用 Heroku 。 確保在項目中添加一個名為 Procfile 的文件並輸入 - web: node index.js 。 並且不要忘記在你的 js 文件中有一個監聽器 - app.listen(process.env.PORT); . 將文件從 git 推送到 Heroku 后，轉到 Heroku 網站，登錄，您將看到已發布的應用程序（可能需要一段時間來構建）。
