所以我试图将我的python flask应用程序部署到ubuntu AWS EC2实例。我已经设置了mod_wsgi，为虚拟主机设置了virtualenv并为服务器创建了静态文件的别名。出于某种原因，我无法获取我的api路由的自定义URL以返回正确的信息。我已经尝试了我到处搜索的所有内容，这是我的最后一个选择。

这是我的访问日志，它正在创建wsgi实例，所以我必须做正确的事。

感谢任何帮助。
这是从我的个人计算机到主机的卷曲请求
djove:.ssh djowinz$ curl http://**.*.**.139/api/v1/getTable
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>
以下是根据请求使用localhost从主机运行到主机的curl请求。

原来这是我如何实例化uwsgi的问题。我从头开始删除所有内容，并使用uwsgi浏览烧瓶安装说明，并且能够使一切工作正常。
