为什么我的应用名称Heroku网站无法使用？应用错误]

Question

我在Udacity课程中使用git将文件从电脑推送到heroku，捆绑应用发布到网络上。

当我使用 https:/git.heroku.commmishal001.git。 根据我的git bash输出 - 它给我的是 Method not allowed

在做研究的时候，有一个堆栈的答案，要使用 https:/mmishal001.herokuapp.com 但它给我一个 Application Error

如何才能成功查看我的网站？

这里是日志。

这是端口信息从 .py 文件。

Answer 1

Heroku会自动给你的heroku应用分配一个端口，所以当你不能把端口设置成一个固定的数字时。Heroku会把端口添加到env中，所以你可以从那里拉它。把你的listen换成这个。

.listen(process.env.PORT || 5000)

这样你在本地测试的时候，它还是会监听5000端口 但在Heroku上也能正常工作。
