Question

我当前的查询如下所示：

router.get('/search?', function(req, res, next) {
    var title = req.query.title;
    var sql = "SELECT * from users WHERE title = ?"; 
    connection.query(sql, [title], function (error, results, fields) {
        res.json({"status": 200, "error": null, "response": results});
    });
});

如果我输入：

localhost:4001/api/v1/users/search?title=mr

但是如何用OR搜索多个值...像这样：

localhost:4001/api/v1/users/search?title=mr,mrs,dr

基本上，

如果查询参数中有多个逗号分隔值，则可以按,拆分它们并使用sql IN clause。

如果您有一个参数值，那么您的方法已经正常工作。

router.get('/search?', function(req, res, next) {
    var title = req.query.title;
    var sql;
    if (title.includes(",")) {
        var params = title.split(",");
        sql = "SELECT * from users WHERE title IN " + params;      
    } else {
        sql = "SELECT * from users WHERE title = " + title;      
    }
    connection.query(sql, function (error, results, fields) {
        res.json({"status": 200, "error": null, "response": results});
    });
});
