使用bcrypt散列密码

如何解决使用bcrypt散列密码

在插入数据库之前，我需要对密码进行哈希处理，我具有bcrypt的功能，但是我不知道如何将其转换为const并用于将其插入MysqL。

我正在使用bcrypt，那么我应该遵循什么方法来对密码进行哈希处理？

  async postCompletedetails(req,res) {
    const company = req.params.company;
    const name = req.params.name;
    const password = req.params.password;
bcrypt.hash(password,saltRounds,(err,hash) => {
});



if (
  company !== undefined &&
  name !== undefined &&
  password !== undefined
) {
    
const { token } = req.headers;
const decoded = jwt.verify(token,process.env.JWT_ACCOUNT_ACTIVATION);
const id = decoded.id;

  const update = await pool.query(
    `UPDATE user SET Name_user= '${name}',password= '${password}' WHERE ID_user = ${id}`
  );
  const incompany = await pool.query(
    `INSERT INTO company (Name_company) VALUES ('${company}') `
  );

  const inrelcompany = await pool.query(
    `INSERT INTO rel_company_user (ID_company,ID_user) VALUES (LAST_INSERT_ID(),${id})`
  );

  return res.json({
    code: 200,message: "todo bien... todo correcto y yo que me alegro",password,});
} else {
  return res.json({
    code: 400,message: "bro hiciste algo mal",});
}

}

解决方法

 async postCompletedetails(req,res) {
    const company = req.params.company;
    const name = req.params.name;
    const password = req.params.password;
    const saltRounds = 10;

if (
  company !== undefined &&
  name !== undefined &&
  password !== undefined
) { 

const hashPass = bcrypt.hash(password,saltRounds,(err,hash) => {
   if (err) 
{
return err; 
}

return hash;
});

hashPass // this will be what you insert into the database.

}

好的，我知道了，但是问题是我无法获取哈希密码，hassPass具有未定义的值，我应该更改什么？

 const hashPass = await bcrypt.genSalt(saltRounds,function (err,salt) {
      if (err) {
        throw err
      } else {
        bcrypt.hash(password,salt,function(err,hash) {
          if (err) {
            throw err
          } else {
            console.log(hash)
          }
        })
      }
    })

密码被散列，现在我输入控制台密码。
