我正在尝试弄清楚如何在 create_engine() 中设置连接超时，到目前为止我已经尝试过:
create_engine(url, timeout=10)
TypeError: Invalid argument(s) 'timeout' sent to create_engine(), using configuration PGDialect_psycopg2/QueuePool/Engine. Please check that the keyword arguments are appropriate for this combination of components.
create_engine(url, connection_timeout=10)
TypeError: Invalid argument(s) 'connection_timeout' sent to create_engine(), using configuration PGDialect_psycopg2/QueuePool/Engine. Please check that the keyword arguments are appropriate for this combination of components.
create_engine(db_url, connect_args={'timeout': 10})
(psycopg2.OperationalError) invalid connection option "timeout"
create_engine(db_url, connect_args={'connection_timeout': 10})
(psycopg2.OperationalError) invalid connection option "connection_timeout"
create_engine(url, pool_timeout=10)
我该怎么办？
最佳答案
正确的方式是这个(connect_timeout而不是connection_timeout):
create_engine(db_url, connect_args={'connect_timeout': 10})
...它适用于 Postgres 和 MySQL
ps:(超时以秒为单位)
