我无法捕获似乎是ConnectionError的错误。这不起作用:
except ConnectionError:
return {
'error_status_code': 500,
'error_message': "Activity Stream connection failed",
}
但这确实可行:
except Exception as e:
if(e.__class__.__name__ == 'ConnectionError'):
return {
'error_status_code': 500,
'error_message': "Activity Stream connection failed",
}
else:
raise e
使用pdb.set_trace()打印e时,我得到:
ConnectionError(MaxRetryError("HTTPConnectionPool(host='localhost', port=8080): Max retries exceeded with url: /v1/ (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x10f00e278>: Failed to establish a new connection: [Errno 61] Connection refused',))",),)
建议它是一个ConnectionError。我也尝试捕获MaxRetryError和NewConnectionError无效。
谢谢
