有什么不对劲？我已经编辑了app_config.py文件，以便有我的凭据。{a2}链接无法工作，我得到以下消息： 内部服务器错误 服务器遇到内部错误，无法完成您的请求。服务器过载或应用程序中存在错误

Answer 1

问题是您缺少了一个模板，正如错误描述的jinja2.exceptions.TemplateNotFound: login.html，login.html文件丢失了，因此如果您遵循提供的示例，您应该注意到根目录下有一个templates目录，其中有HTML模板和您需要的login.html>https://github.com/Azure-Samples/ms-identity-python-webapp/tree/master/templates
