mysql - json 到 mysql 使用 node.js

Question

我试图将在 node.js 中创建的 json 插入到 mysql 中， 但是语法有错误，我无法纠正错误， 任何帮助将不胜感激

我的代码

flowController.on('2', function (_selfid,_participantId,_groupid,_allMemberContent) 
        {
    var allMemberDetailSQL= "SELECT spFunAllMemberNotificationDetails("+ _selfid + "," + _participantId +") as groupparticipants";
    console.log("allMemberDetailSQL"+allMemberDetailSQL);

client.query(allMemberDetailSQL,function(detailERROR,detailResult)
        {
            if (detailERROR)
                console.log("detailERROR "+ detailERROR);
            else 
            {

                var detailstr='';
                detailstr = JSON.stringify(detailResult);
                console.log('detailResult :'+ detailstr);
                console.log("detailResult "+detailResult[0].groupparticipants);
                var otherArray = [detailResult[0].groupparticipants];


                var _allMemberDetail = JSON.stringify({
                    selfid: _selfid,
                    groupid: _groupid, 
                    anArray: otherArray
                  });

                console.log("_allMemberDetail " +_allMemberDetail);

                var allMemberDetail = "'"+_allMemberDetail+"'";
                console.log("allMemberDetail "+allMemberDetail);
                client.query("INSERT INTO cmNotification (notificationSenderId, notificationReceiverId)"+"VALUES('"+_selfid+"','"+ _allMemberDetail+ "');", function(err, rows)
                         {
                            console.log("error insert "+err);
                            console.log("rows insert"+rows);
                            //connection.release();

                          });
            }

        });

});

控制台输出

allMemberDetailSQLSELECT spFunAllMemberNotificationDetails(20,16) as groupparticipants
detailResult :[{"groupparticipants":"userid:'15',firstname:'pitu15',lastname:'',isfriend:'1',profilepicurl:''"}]

使用内置 parameters escaping防止sql注入(inject)攻击。 “插入……设置？”也让生活更轻松:

client.query("INSERT INTO cmNotification SET ?",  {notificationSenderId: _selfid, notificationReceiverId: _allMemberDetail}, function(err, rows) {
  // ...
});
