问题 Consider the following code in my WebApp2 application in Google App Engine: count = 0 class MyHandler(webapp2.RequestHandler): def get(self): global count count = count + 1 print count With each refresh of the page, the count increments higher. I'm coming from the PHP world where every request was a new global environment. What I understand to be happening here is, because I'm using the wsgi configuration for WebApp2, Python does not kick off a new process on each request. If I was using a

问题 Could you supply a real-life example of WSGI start_response function? (Web-server provides that function to wsgi application) I can't understand the purpose of introducing the start_response . (I've read like 10 identical texts about the WSGI standard. They all say "WSGI standard is..." None of them says "WSGI is designed this way in order to ..." :() 回答1: Could you supply a real-life example of WSGI start_response() function? Well, the start_response() function for mod_wsgi is defined on

问题 I have a folder called python2.7 inside of lib in the virtual environment. After reading half a dozen tutorials, I can't figure out exactly what I'm suppose to point the WSGIPythonPath to. I've seen some pointing to site-packages but some have been a colon : separated list. Syntax error on line 1019 of /etc/httpd/conf/httpd.conf: WSGIPythonPath cannot occur within <VirtualHost> section Where should WSGIPythonPath point in my virtualenv? 回答1: You are getting the error because WSGIPythonPath

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . To help further my understanding of WSGI I'm looking for a diagram which explains the flow of an application, from webserver (eg. apache) through a number of middlewares to "code" (as in, the print "hello world" bit). I've read various articles regarding WSGI from wsgi.org, but it's still not "clicking" for me

问题 I have read the official Flask documentation on Blueprints and even one or two blog posts on using them. I've even used them in my web app, but I don't completely understand what they are or how they fit into my app as a whole. How is it similar to an instance of my app but not quite? The documentation is comprehensive but I seek a layman explanation or an enlightening analogy to spark it for me. I was sufficiently perplexed when a colleague asked me to explain a Flask blueprint to them that

问题 I have seen plenty of previous messages related to my problem, but no answer could get rid of my "500 Server internal Error" so I try to post my conf to get help.

问题 I have WSGI middleware that needs to capture the HTTP status (e.g. 200 OK ) that inner layers of middleware return by calling start_response . Currently I'm doing the following, but abusing a list doesn't seem to be the “right” solution to me: class TransactionalMiddlewareInterface(object): def __init__(self, application, **config): self.application = application self.config = config def __call__(self, environ, start_response): status = [] def local_start(stat_str, headers=[]): status.append

问题 I'm using CherryPy in order to serve a python application through WSGI. I tried benchmarking it, but it seems as if CherryPy can only handle exactly 10 req/sec. No matter what I do. Built a simple app with a 3 second pause, in order to accurately determine what is going on... and I can confirm that the 10 req/sec has nothing to do with the resources used by the python script. __ Any ideas? 回答1: By default, CherryPy's builtin HTTP server will use a thread pool with 10 threads. If you are still

问题 Does anyone know how to make a mod_wsgi automatically reload a Flask app when any of the modules changes? I've tried WSGIScriptReloading On , but no luck. The official documentation is kind of a bear ... I guess I'll give it a stab if no one knows. Thanks in advance! Also, if it could not permanently crash on syntax errors (like the the Flask reloader), that'd be awesome. 回答1: With mod_wsgi , WSGIScriptReloading looks for changes to the .wsgi config file, rather than the code. My workflow is
