Question

我正在使用python webapp2（在GAE中使用）。我在日志记录中看到了此异常。

<bound method PythonBreakpoint._ActivateBreakpoint of <google.devtools.cdbg.debuglets.python.python_breakpoint.PythonBreakpoint object at 0x2ab09434da10>>

KeyError: <bound method PythonBreakpoint._ActivateBreakpoint of <google.devtools.cdbg.debuglets.python.python_breakpoint.PythonBreakpoint object at 0x2ab09434da10>>

这是我的代码。

import webapp2
ROUTES = [
    webapp2.Route('/sample', handler='sample_package.SampleClass', methods=['POST']),
...
]

APPLICATION = webapp2.WSGIApplication(
    ROUTES,
    config=config)

此异常并非每次都发生。

这是什么意思，我该如何删除？有问题吗？

您是否在调用不带（）的函数？

a = b.func()或a = b.func？

如果不包含括号，则可能是返回对函数的引用，而不是函数的输出。

“绑定方法PythonBreakpoint._ActivateBreakpoint”是什么意思？
