好吧，我对这一切都很陌生，所以如果没有发现“明显”的问题，我很抱歉。我试图使用postman发布数据，但我不断得到这个错误。有人知道问题出在哪里吗？

{

    "error": {
        "code": "ER_PARSE_ERROR",
        "errno": 1064,
        "sqlMessage": "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'itemData.GPU\", \"itemData.storage\", \"itemData.size\", \"itemData.price\")' at line 1",

        "index": 0,
        "sql": "INSERT INTO orderdetails (userID, title, device, type, CPU, RAM, GPU, storage, size, price) VALUES (\"itemdata.userID\", \"itemData.title\", \"itemData.device\", \"itemData.type\", \"itemData.CPU\", \"itemData.RAM, \"itemData.GPU\", \"itemData.storage\", \"itemData.size\", \"itemData.price\");"
    }
}

我试图发布的数据：

{
    "userID":1,
    "title":"Nitro 5 Spin Laptop | NP515-51 | Black",
    "device":"laptop",
    "type":"Convertible",
    "CPU":"i5-8250U",
    "RAM":"8 GB",
    "GPU":"GTX 1050",
    "storage":"SSD",
    "size":"256 GB",
    "price":1099
}

.

module.exports.add = function(conData, itemData, callback){
        db.connect(conData, function(err, conn){

            if (err) {
                callback(err);
                return;
            }

            conn.query("INSERT INTO orderdetails (userID, title, device, type, CPU, RAM, GPU, storage, size, price) VALUES (\"itemdata.userID\", \"itemData.title\", \"itemData.device\", \"itemData.type\", \"itemData.CPU\", \"itemData.RAM, \"itemData.GPU\", \"itemData.storage\", \"itemData.size\", \"itemData.price\");", itemData, function(err,result){

                callback(err, result);
            });
        });
