我仍然遇到webapp2错误，并且很茫然，这里可能是问题所在。

请注意，我正在使用GAE的最新SDK版本（1.6.0）。
我的代码如下所示：
app.yaml
application: test-app
version: 1
runtime: python27
api_version: 1
threadsafe: true
handlers:
- url: /favicon\.ico
static_files: static/images/favicon.ico
upload: static/images/favicon\.ico
- url: .*
script: main.site_app
login: required
libraries:
- name: django
version: "1.2"
main.py
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
import webapp2
import urls
site_app = webapp2.WSGIApplication(urls.SITE_URLS, debug=True)
urls.py
import webapp2
import handler
SITE_URLS = [
webapp2.Route(r'/', handler.TestHome),
webapp2.Route(r'/test/<test_key:\w+>', handler.TestPage)
]
basehandler.py
import os
import webapp2
from django import template
class BaseHandler(webapp2.RequestHandler):
def __init__(self, *args, **kwargs):
self.tdict = {}
def render(self, template_file):
template_path = os.path.join(os.path.dirname(__file__),
'templates',
template_file)
t = template.Template(file(template_path,'rb').read())
self.response.write(t.render(template.Context(self.tdict)))
handler.py
import os
from basehandler import BaseHandler
class TestHome(BaseHandler):
def get(self):
def get(self):
self.render('browse.html')
class TestPage(BaseHandler):
def get(self, test_key):
self.tdict['test_key'] = test_key
self.render('browse.html')
templates / browse.html
<html>
<head>
<title>Success!</title>
</head>
<body>
Success!
{% if test_key %}- {{ test_key }}{% endif %}
</body>
</html>
我究竟做错了什么？任何帮助/建议都将不胜感激！
最佳答案
我认为这是因为您没有调用webapp2.RequestHandler.__init__()。这是webapp2.py的代码片段：
class RequestHandler(object):
# ...
def __init__(self, request=None, response=None):
self.initialize(request, response)
如您所见，
RequestHandler用request和response初始化。因此，您必须在代码中做同样的事情：class BaseHandler(webapp2.RequestHandler):
def __init__(self, request, response):
self.tdict = {}
self.initialize(request, response)
关于python - AttributeError:'NoneType'对象没有属性'route'和webapp2，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/8488482/
