我正在尝试使用 Google App Engine 构建一个(新手)应用程序，但是当我运行它时，我发现了这个我不理解的(日志)错误:
File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1479, in __init__
self.router = self.router_class(routes)
File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1129, in __init__
self.add(route)
File "C:\Program Files (x86)\Google\google_appengine\lib\webapp2\webapp2.py", line 1142, in add
for r in route.get_match_routes():
AttributeError: 'str' object has no attribute 'get_match_routes'
INFO 2012-04-29 14:42:34,056 dev_appserver.py:2891] "GET / HTTP/1.1" 500 -
完整代码如下。有人能找出这个错误的原因以及我该如何解决吗？ 在此先感谢您的帮助!

app = webapp2.WSGIApplication([('/', MainHandler), '/welcome', WelcomeHandler],

最佳答案
修复你的路由定义:
app = webapp2.WSGIApplication([(r'/', MainHandler),
(r'/welcome', WelcomeHandler)],
debug=True)
同时检查 webapp2 routing extended对于更高级的东西。
关于python - 为什么这段代码会得到 this 'str' object has no attribute 'get_match_routes' 错误？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10373309/
