GAE 命令纪要

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" %}

{% block logo %}

{% endblock %}

 

phrase = singular if count == 1 else plural

 

import game_ajax
import lobby_ajax
import gamemodel

 

players = lobby.lobby_list(50)

return map(lambda obj:obj.player.nickname(), players)

 

active_games = gamemodel.public_game_list()

active_games = filter(lambda gameObj: gameObj.player1 != user and gameObj.player2 != user, active_games)

 

{% include "header.html" %}
