为什么Heroku网站无法使用我的应用名称？ [应用程序错误]

Question

我已经使用git将文件从计算机推送到heroku，该捆绑了该应用，以便在Udacity课程期间在网络上发布。

当我根据git bash输出使用https://git.heroku.com/mmishal001.git时-它给了我Method not allowed

在进行研究时，有一个使用https://mmishal001.herokuapp.com/的答案，但是它给了我Application Error

如何成功查看我的网站？

这是.py文件中的端口信息，

Answer 1

Heroku自动为您的heroku应用程序分配一个端口，因此当您无法将端口设置为固定编号时。 Heroku将端口添加到环境中，因此您可以从那里拉出它。切换至此：

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

这样，当您在本地测试时，它仍然会监听端口5000，但它也可以在Heroku上运行。
