无法更改Python Web.py应用程序Linode示例

Question

I am following this web.py Hello World example:

https://library.linode.com/web-servers/nginx/python-uwsgi/ubuntu-12.04-precise-pangolin#sph_more-information

Now I get the "Hello World!" example from above page perfectly to run in my Browser, but when I want to change the application to my need, eg make a fully AJAX app out of it like this:

urls = ('/(.*)', 'Index')

application = web.application(urls, globals())

web.config.debug = True

class Index:
def POST(self):
    content = web.input(_method='post')
    return 'Ajax Test Data'

if __name__ == '__main__':application.run()

I get the following error (even if I make minor changes to the "application" function from Linode)

uWSGI Error

Python application not found

How can I get this to work with my own code?

---

I uninstalled the Debian packages and installed the pip package with build-in Python. I also had to clean up / unify my .ini and -xml configuration files.

I then started my app with

uwsgi -s /tmp/uwsgi.sock -w app

The biggest help came from this document

However, I encountered a web module not found error , so I rolled back to the Linode example and am currently fiddling around with it, still trying to get my app called from inside the application wrapper.

Hi Look at this stackoverflow post: uwsgi error python application not found

You need to kill the old uWSGI process, which is searching for the old instance of the app, which no longer exists because you changed it.

Answer 2

Instead of running the app with if __name__ == '__main__':application.run() , you need to "export" WSGI application to uWSGI. By default uWSGI looks for a WSGI callable named application , but the application you have is not a WSGI callable. So remove if __name__ == '__main__':application.run() and replace application = web.application(urls, globals()) with application = web.application(urls, globals()).wsgifunc() .
