Question

我收到此错误，很不幸，我尝试使用web.py创建一个简单的Web项目，当我尝试注册用户时遇到了错误，并且我已经尝试过更改属性，但无法解决问题< / p>

Date

我已经检查了文件（Main.py，RegistrationModel.py和Register.HTML），但没有找到错误。

File "C:\Users\Pippo\Anaconda3\lib\site-packages\web\utils.py", line 75, in   __getattr__
    return self[key]
KeyError: 'name'

During handling of the above exception, another exception occurred:

127.0.0.1:55572 - - [15/Aug/2019 20:54:31] "HTTP/1.1 POST /postregistration" - 500 Internal Server Error

任何想法为何会出现此错误？

感谢您的帮助！

Answer 1

您似乎没有在POST请求的有效载荷中传递name。

您可以使用forms模块来验证输入。

http://webpy.org/cookbook/forms

或者如果web.input是可选输入，则将默认值指定为name。

data = web.input(name="default-name")

如何修复500 Internal Server Error / web.py
