通过dns连接时，Nginx无法正确返回html模板

时间：2016-01-05 22:48:04

标签： python ubuntu nginx flask uwsgi

您好我为我的组织制作了一个网络应用程序，我目前正在部署到ubuntu服务器上。 Web应用程序是用python构建的，带有烧瓶和其他一些扩展，它在dev中工作得很好，但是当我部署它时，我得到一些奇怪的错误，我无法看到它的目的。

  • 用烧瓶进行施用
  • ＆＃34;前端＆＃34;是nginx

  • uwsgi正在处理nginx的python

  • 服务器在WM上运行最新的ubuntu服务器

  • 我可以通过我的浏览器中的ip-adress从我的局域网中的另一台计算机到达应用程序，工作正常并分配到nginx中的端口80，所以我不要必须自己键入任何端口。 （烧瓶本身被设置为localhost：8080用于测试追求）。

  • 我不能让我的服务器回复除502和404之外的任何错误，当我尝试通过我的dns指向我的传出ip连接，也不能直接连接到传出的IP。但是我可以在其中一个错误日志中看到，似乎服务器处理我的请求，但是其中一个烧瓶出现了一个奇怪的错误＆＃34; current_user＆＃34;模块。我将转储下面的所有日志。

包含python错误的

感谢我能得到的所有帮助！

True

Flase将返回()或{% if current_user.is_authenticated %} ，但您调用它，它是一个布尔值。

解决方案很简单，你应该使用它，而不是double threshold = 0.7; Math.round(x - threshold + 0.5); ：
