webapp2

问题 I am trying to run webapp2 under Python with Apache and mod_wsgi - specifically: Wampserver for Windows 7 with Apache 2.2.22. So far, I have failed miserably. :-( I used the following example from https://developers.google.com/appengine/docs/python/gettingstartedpython27/usingwebapp: import webapp2 class MainPage(webapp2.RequestHandler): def get(self): self.response.headers['Content-Type'] = 'text/plain' self.response.out.write('Hello, webapp World!') app = webapp2.WSGIApplication([('/',

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.

问题 I know about this question. But you can’t write to filesystem in app engine (shutil or zipfile require creating files) . So basically I need to archive something like /base/nacl using zip or tar, and write the output to the web browser asking the page (the output will never exceed 32 Mb) . 回答1: It just happened that I had to solve the exact same problem tonight :) This worked for me: import StringIO import tarfile fd = StringIO.StringIO() with tarfile.open(mode="w:gz", fileobj=fd) as tgz: tgz

问题 friends! I'm fairly new to web app world and I have a question regarding Google AppEngine functions. I've installed the Launcher on my machine and signed up for the online platform (Python). I've added my project folder in the Launcher and hit "deploy" to have it online. However, when I edit/update my "main.py" file to move forward in the development the edits are not reflected online. In other words: I don't see any change, when I go to the link: [NAME].appspot.com and in fact, checking at

问题 I make my first MLM software and I think I managed to code how to get the points from the downline even though it is a recursive problem I didn't use recursion and I might refactor to a recursive version if that seems better. With our system, the level of a distributor is measured i number of silvers and for each product that gets sold the promotion/bonus/score/points works upline so if Bob is the sponsor of Alice and Alice makes a purchase then Bob will get points measured in number of
