nodejs中怎么判断oracledb连接是否断开

Answer 1

尝试获取数据，如果报错，特别是报连接断开的错误，则表明已经断开
router.get('/', function (req, res, next) { var oracledb = require('oracledb');
oracledb.getConnection(
{
user: 'username',
password: 'password',
connectString: '192.168.20.10:1521/ORCL'
}, function (err, connection) { if (err) {
console.error(err.message); return;
}
connection.execute( "SELECT * from CMS_FIlE where content_id=:id",
[1072], // bind value for :id
function (err, result) { if (err) {
console.error(err.message); return;
}
res.render('index', {title: '查询信息：' + JSON.stringify(result.rows)});
});
});

});
