Nodejs: TypeError: Cannot read property 'rows' of undefined hashing password

Question

我正在尝试在我的注册中散列密码，起初当我没有散列码时，代码可以工作但是当我添加散列码功能时，我收到这个错误，请检查下图，

async function postUser(req, res, next){
    params = req.body;//post
    let validation_rules = {
        email: 'email|required',
        firstname: 'required',
        lastname: 'required',
        middlename: 'required',
        position: 'required',
        departmentid: 'required|integer',
        phonenumber: 'required',
        whatyoudo: 'required',
        password: 'required|confirmed|min:8',
    };

    let validation = new Validator(params, validation_rules);
    console.log("params", params);

    if(validation.passes())
    {
        try
        {   
            params.profilephotourl = "photourlsoon";
            let results = await user.newUser(params);

            res.status(200).json(results.rows);
        }catch(err){
            console.log("-----result data error-----\n", err);
            res.status(500).json(err);
        }
    }else{
        res.status(400).json(validation.errors);
    }
}

//

exports.newUser = async function(data){
    try {
        bcrypt.hash(data.password, saltRounds, function(err, hash) {
        let sql = 'CALL "'+config.DBSchemaAAM+'"."sp_Users_insert"(\''+data.email+'\', \''+data.lastname+'\',\''+data.firstname+'\',\''+data.middlename+'\',\''+data.profilephotourl+'\', \''+data.position+'\', \''+data.whatyoudo+'\',\''+data.phonenumber+'\', '+data.departmentid+', \''+hash+'\')';
        console.log(sql);
        return pool.query(sql,)
        .then((res) => { return res;})
        .catch((err) => { return console.error('---Error executing query---\n', err.stack) });  
    });
    } catch(err) { return console.error(err); } 
}

错误

TypeError: Cannot read property 'rows' of undefined

Answer 1

错误发生是因为您在调用 bcrypt.hash 函数时使用了回调函数，因此您的函数 newUser returns undefined 是预期的。

这里是重写函数的方法。

exports.newUser = async function(data) {
    try {
        return bcrypt.hash(data.password, saltRounds).then((hash) => {
          let sql = 'CALL "'+config.DBSchemaAAM+'"."sp_Users_insert"(\''+data.email+'\', \''+data.lastname+'\',\''+data.firstname+'\',\''+data.middlename+'\',\''+data.profilephotourl+'\', \''+data.position+'\', \''+data.whatyoudo+'\',\''+data.phonenumber+'\', '+data.departmentid+', \''+hash+'\')';
          console.log(sql);

          return pool.query(sql,)
                         .catch((err) => { return console.error('---Error executing query---\n', err.stack) });  
        });
    } catch(err) { return console.error(err); } 
}

也与问题无关，但值得一提的是，你不应该只是将从用户那里收到的数据放入 SQL 查询中，你应该使用准备好的语句，否则你可能会受到 SQL 注射.
