独角兽工人超时

我在Nginx后面的Gunicorn中运行了一个Django应用程序.一切正常，针对一件奇怪的事情进行说明:我有一个下载"视图和一个RESTful json API.调用下载视图时，我使用urllib2访问json API以获取信息.确切地说，当我尝试向json api执行此http get请求时，该请求超时并显示错误HTTP错误504:网关超时.

I have a Django application running in Gunicorn behind Nginx. Everything works fine, exect for one strange thing: I have a "download" view and a RESTful json API. When call the download view I use urllib2 to access the json API to get information. And excactly when I try to do this http get request to the json api, the request times out with an error HTTP Error 504: Gateway Time-out.

当我使用./manage.py runserver运行代码时，一切正常.到json api的http get请求也只需几毫秒，因此没有发生超时的危险.

When I run the code with ./manage.py runserver everything works fine. The http get request to the json api also only takes a few miliseconds, so no danger of running into a timeout.

以下是伪代码中的情况:

Here the Situation in Pseudo code:

myproject/views.py:(可通过以下方式访问: http://myproject.com/download )

myproject/views.py: (accessible as: http://myproject.com/download)

1   def download(request, *args, **kwargs):
2       import urllib2
3       opener = urllib2.build_opener()
4       opener.open('http://myproject.com/api/get_project_stats')

在Gunicorn中运行时，第四行中的opener.open()调用会超时，当与./manage.py runserver一起运行时，一切正常(并且api调用只需要几毫秒.

The opener.open() call in line four runs into a timeout when running in Gunicorn, when running with ./manage.py runservereverytihng works fine (and the api call only takes a few miliseconds.

有人遇到过同样的问题吗?更重要的是:您是如何解决的?
