优化以下代码exportsgetSelectBlogs = req res = const info = reqbody; const sqlStr = select from blogs_info where title LIKE ; dbquerysqlStr infotitle err results = if err return rescce

exports.getSelectBlogs = (req, res) => { const info = req.body; const title = %${info.title}%;

const sqlStr = `select * from blogs_info where title LIKE ?`;
db.query(sqlStr, title, (err, results) => {
    if (err) return res.cc(err);
    if (results.length === 0) return res.cc("查询文章失败,该文章不存在");
    res.send({
        status: 0,
        message: "查询成功",
        data: results
    });
