Question

我有一个聚合物应用程序，我正在部署到Google App Engine。它是the beginner polymer tutorial的第2步。我一直在为某些资源获取404和500错误，特别是这些错误：

GET http://polymer-test-nik.appspot.com/images/avatar-07.svg 404 (Not Found) polymer-test-nik.appspot.com/:66
GET http://polymer-test-nik.appspot.com/components/core-header-panel/core-header-panel.html 500 (Internal Server Error) polymer-test-nik.appspot.com/:10
GET http://polymer-test-nik.appspot.com/images/avatar-07.svg 404 (Not Found) polymer-test-nik.appspot.com/:66
GET http://polymer-test-nik.appspot.com/components/core-selector/core-selector.html 500 (Internal Server Error) polymer-test-nik.appspot.com/:78

目录结构与教程相同。

我使用简单的main.py来提供应用

import random
import os
from google.appengine.ext import webapp
from google.appengine.ext.webapp import util
from google.appengine.ext.webapp import template

class MainHandler(webapp.RequestHandler):
  def get (self, q):
    if q is None:
        i = random.randint(1,11)
        q = 'step-2/index.html'
    path = os.path.join (os.path.dirname (__file__), q)
    self.response.headers ['Content-Type'] = 'text/html'
    self.response.out.write (template.render (path, {}))

class GuideHandler(webapp.RequestHandler):
  def get (self, q):
    q = 'icgt-registration-guide.pdf'
    path = os.path.join (os.path.dirname (__file__), q)
    self.response.headers ['Content-Type'] = 'application/pdf'
    self.response.out.write (template.render (path, {}))

def main ():
  application = webapp.WSGIApplication ([('/(.*html)?', MainHandler)], debug=True)
  util.run_wsgi_app (application)

if __name__ == '__main__':
  main ()

将以下内容添加到app.yaml：

handlers:
- url: /components
  static_dir: components
- url: /images
  static_dir: images

值得注意的是，这些处理程序应该在 url: .*声明之后添加，否则它将捕获所有并且永远不会进一步下降，所以在这个简单的示例中，完整声明将如下所示：

handlers: - url: /components static_dir: components - url: /images static_dir: images - url: .* script: main.py

我还建议您使用webapp2 framework代替它，建议新的应用程序以及更好的方式！
