我正在使用 Httpretty 来模拟 Web API。

如果我使用httpretty.enable(allow_net_connect=False)（当 allow_net_connect 为 False 时，任何与未注册 uri 的连接都会抛出 httpretty.errors.UnmockedError），我会收到一个错误，因为 pymysql 无法通过套接字连接到本地数据库。

但是，当我使用 时httpretty.enable(allow_net_connect=True)，我从丢失的连接中得到一个错误。

            except (IOError, OSError) as e:
                if e.errno == errno.EINTR:
                    continue
                self._force_close()
                raise err.OperationalError(

../../.virtualenvs/3.6espiga/lib/python3.6/site-packages/pymysql/connections.py:1037: OperationalError

如何让 Httpretty 模拟 Web API 并让数据库连接正常运行？
