基础：
dev_appserver.py，开发网络服务器
appcfg.py，用于将您的应用程序上传到 App Engine
app.yaml
一个 webapp 应用程序包含三部分：
一个或多个 RequestHandler 类，用于处理请求和构建响应
一个 WSGIApplication 实例，按照网址将收到的请求发送给处理程序
一个主要例行程序，用于使用 CGI 适配器运行 WSGIApplication
import cgi
import os
from google.appengine.ext import db
from google.appengine.ext import webapp
from google.appengine.ext.webapp import template
from google.appengine.ext.webapp.util import run_wsgi_app
class Greeting(db.Model):
class MainPage(webapp.RequestHandler):
def get(self):
class Guestbook(webapp.RequestHandler):
def post(self):
application = webapp.WSGIApplication(
[('/', MainPage),
('/sign', Guestbook)],
debug=True)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
进阶：
import urllib
def get(self, user):
unescaped_user = urllib.unquote(user)
greeting_user_object = users.User(unescaped_user)
('/edituser/([^/]+)', EditUserProfileHandler)
greetings_query = Greeting.all().order('date')
greetings = greetings_query.fetch(1000)
class BaseRequestHandler(webapp.RequestHandler):
class MainRequestHandler(BaseRequestHandler):
class ChatsRequestHandler(BaseRequestHandler):
directory = os.path.dirname(__file__)
path = os.path.join(directory, 'templates', template_name)
self.response.out.write(template.render(path, values, debug=_DEBUG))
next：
{% extends "base.html" %}
