When pserve starts by default it runs the pyramid application in http://0.0.0.0:6543 however how can I changed it to http://0.0.0.0:6543/myapp
In the settings I can change the port but I haven't found elsewhere where to change the root path
回答1:
In any WSGI application the environ['SCRIPT_NAME'] is very important here. It defines the root path for all urls in the app. The full path is environ['SCRIPT_NAME'] + environ['PATH_INFO']. Assuming you have done things properly in your app (for example request.route_url(..) will generate urls using this information) then you can simply remount your application elsewhere (the default SCRIPT_NAME is '') by instructing it that it should be something else.
There are a couple things you can do based on how you're deploying your application (if it's behind a proxy then things are slightly more complex). Let's assume you're just using a simple pyramid app hosted with waitress. You can move your app using the rutter[1] package which will match the /myapp/* path and send all requests to your app with the appropriate SCRIPT_NAME (myapp) and PATH_INFO.
The declarative config is the simplest for a pyramid app. Just install rutter and then update your INI file to mount your application at /myapp prefix:
[app:foo]
use = egg:myapp#main
[composite:main]
use = egg:rutter#urlmap
/myapp = foo
Note I renamed the app:main to app:foo because you can only have one wsgi component named main and we want it to be the composite.
