Decorators for WSGI without start_response and write
Project description
wsgistraw (WSGI without STart_Response And Write) is a tiny Python library that simplifies coding WSGI applications and middleware by removing start_response and write from signatures of functions. This leads to a signature like:
def app(environ):
return "200 OK", [("Content-Type", "text/plain")], ["Hello World!"]
That is, return a three-tuple of (status, headers, response).
start_response and write are very annoying in WSGI middleware. wsgistraw makes your middleware code cleaner. This is an example of a “lowercase” middleware factory:
@wsgistraw.mid_factory
def lowercase(app):
def mid(environ):
status, headers, response = app(environ)
return status, headers, (s.lower() for s in response)
return mid
What’s New
Added app_proxy, fixed a couple of inconsistencies with PEP 333.
(+) Added public app_proxy class (former _app_proxy, thanks to Ian Bicking)
(-) If an app uses write() then app_proxy invokes response.close() after iterating over it
(-) If an app hasn’t invoked start_resposnse() before returning then app_proxy forces this invocation by calling response.next()
