python - Heroku EOFError 仅适用于两行 python 代码

Question

这是我第一次尝试将 python 程序部署到 Heroku。

我的Python程序是

name=input("What is your name?: ");
print("Nice to meet you", name)  

和https://shielded-gorge-83102.herokuapp.com/说

Application error 
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail 

执行日志命令时:

我读了这篇文章:App crashing on Heroku Pyphon application

它说你不能在此处使用输入命令。这是因为它是一个网络应用程序并且打印命令无法在浏览器上运行吗？请告诉我如何在不接受输入的情况下运行该程序。

所以，如果我们需要一点 HTML，我也知道如何使用 HTML。所以请帮助我使用 python 运行这个程序。

Answer 1

您仍然可以进行输入，但方式略有不同。看看这个Send data from a textbox into Flask?

一旦您有了一个简单的应用程序，请按照本教程进行部署 https://devcenter.heroku.com/articles/getting-started-with-python

您很可能已经了解大部分步骤。而且并非所有这些都是强制性的。
