flask-restful异常的问题

Question

谁用过flask-restful?
按照它提供的案例写测试正常。加到自己项目里，如果引发错误，一律无法捕捉，只有以下提示：

File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1701, in __call__
    return self.wsgi_app(environ, start_response)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1689, in wsgi_app
    response = self.make_response(self.handle_exception(e))
  File "/usr/local/lib/python2.7/dist-packages/flask_restful/__init__.py", line 271, in error_router
    return original_handler(e)
  File "/usr/local/lib/python2.7/dist-packages/flask_restful/__init__.py", line 268, in error_router
    return self.handle_error(e)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1687, in wsgi_app
    response = self.full_dispatch_request()
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1360, in full_dispatch_request
    rv = self.handle_user_exception(e)
  File "/usr/local/lib/python2.7/dist-packages/flask_restful/__init__.py", line 271, in error_router
    return original_handler(e)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1246, in handle_user_exception
    assert exc_value is e
AssertionError

建议到Flask源代码里面去调试一下，改一下flask源代码，看看assert语句中 exc_value 和 e 分别是什么，如果纯粹是捕捉错误的话：

except (AssertionError) as e:
    pass
