得到的request的URL地址，我们就可以根据request的URL地址用GAE动态的生成网页内容。

from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
 
class MainPage(webapp.RequestHandler):
  def get(self):
    header = str(self.request)
    self.response.headers['Content-Type'] = 'text/plain'
    self.response.out.write('Hello, webapp World!\n')
    self.response.out.write(header)
 
application = webapp.WSGIApplication(
                                     [('/.*', MainPage)],
                                     debug=True)
 
def main():
  run_wsgi_app(application)
 
if __name__ == "__main__":
  main()

访问下面的地址时

http://localhost:8080/dfasf

可以得到

Hello, webapp World!
