Python 返回500个错误

因此，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，将虚拟主机设置配置为virtualenv，并创建了别名来为静态文件提供服务器。由于某些原因，我无法获取api路由的自定义url以返回正确的信息。我已经尝试了所有我搜索过的地方这是我最后的选择

这是WSGI文件oakapp.WSGI

from app import app as application

这是虚拟主机环境

感谢您的帮助

下面是从我的个人计算机运行到主机的curl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>

下面是根据请求使用localhost从主机运行到主机的curl请求

    root@ip-172-31-24-66:/var/www/oakapp# curl http://localhost/api/v1/getTable
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">

    <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>

事实证明，这是我如何实例化uwsgi的一个问题。我从头开始删除了所有内容，并使用uwsgi浏览了烧瓶安装说明，使所有内容都能正常工作。

可以使用curl output？@kracekumar本地或远程显示请求和响应，例如从服务器或我的个人机器？它没有提供足够的关于/api/v1/getTable的信息。这看起来不像是配置问题。查看/var/www/oakapp/logs/oakapp_error.log中的内容。这可能会给你一些线索。@kracekumar[Tue Apr 28 05:03:56.050981 2015][：error][pid 3574:tid 140512686647040][remote 72.219.180.235:10929]TypeError:“module”对象不可调用问题是你使用的函数/方法是module。我认为你应该很容易从这里开始。
