我无法找到与mysql代码的错误

我是新手。我无法从前端插入数据到MySQL数据库。我在插入时遇到问题。我无法找到与mysql代码的错误

我index.js代码

我存放在变量形式的细节，试图将其插入到数据库

router.post('/signup',function(req,res,next) { 
    var item = req.body; 
    connection.connect(function(err){ 
     var sql = "INSERT INTO details VALUES ? "; 
     connection.query(sql,[item]); 
    }); 
    res.render('data' ,{items:item}); 
});

错误消息

     throw err; // Rethrow non-MySQL errors 
     ^

什么_exactly_是'req.body'的内容？ “SHOW CREATE TABLE details”的MySQL输出是什么？ – hunteke

这不是有效的SQL语法。您不能使用一堆这样的值的占位符，则必须分别突破出来：

connection.query(
    "INSERT INTO details (name, pwd) VALUES (?,?)", 
    [ "Name", "Pwd" ] 
);

一次性将所有这些条件作为一个占位符有将它们封装一个字符串，它打破了内部的影响句法。

重要信息：始终对您的密码进行哈希处理，切勿使用纯文本进行存储。在绝对至少use Bcrypt这是专门用于密码，而不是一些像SHA1一样的高速散列或像MD5一样的受损散列。

如果您使用的是节点，您可能希望至少考虑使用Passport，它可以为您做很多繁重的工作，并且可以与其他Node组件搭配使用。
