Javascript b crypt/Mongoose更改用户密码

Javascript b crypt/Mongoose更改用户密码,javascript,node.js,mongodb,mongoose,bcrypt,Javascript,Node.js,Mongodb,Mongoose,Bcrypt,我正在尝试将更改密码选项添加到我构建的仪表板中。我的表单有三个输入:currentPassword、newPassword、confirmNewPassword。这是您的标准对照数据库检查当前密码,如果它匹配,则使用新密码更新它 无论我做什么,我都无法在匹配成功的地方运行代码(bcrypt.compare之后的代码)。我知道我使用的是正确的密码。我不知道我做错了什么。谢谢你的帮助 router.post("/changepassword", ensureAuthenticat

我正在尝试将更改密码选项添加到我构建的仪表板中。我的表单有三个输入:currentPassword、newPassword、confirmNewPassword。这是您的标准对照数据库检查当前密码,如果它匹配,则使用新密码更新它

无论我做什么,我都无法在匹配成功的地方运行代码(bcrypt.compare之后的代码)。我知道我使用的是正确的密码。我不知道我做错了什么。谢谢你的帮助

    const userID = req.user.userID;
    let errors = [];

    //Check required fields
    if (!currentPassword || !newPassword || !confirmNewPassword) {
        errors.push({ msg: "Please fill in all fields." });
    }

    //Check passwords match

                    bcrypt.genSalt(10, (err, salt) =>
                        bcrypt.hash(newPassword, salt, (err, hash) => {

尝试使用异步等待语法

router.post("/changepassword", ensureAuthenticated, async (req, res) => {
  const { currentPassword, newPassword, confirmNewPassword } = req.body;
  const userID = req.user.userID;
  let errors = [];

  //Check required fields
  if (!currentPassword || !newPassword || !confirmNewPassword) {
    errors.push({ msg: "Please fill in all fields." });
  }

  //Check passwords match
  if (newPassword !== confirmNewPassword) {
    errors.push({ msg: "New passwords do not match." });
  }

  //Check password length
  if (newPassword.length < 6 || confirmNewPassword.length < 6) {
    errors.push({ msg: "Password should be at least six characters." });
  }

  if (errors.length > 0) {
    res.render("changepassword", {
      errors,
      name: req.user.name,
    });
  } else {
    //VALIDATION PASSED
    //Ensure current password submitted matches

    User.findOne({ userID: userID }).then(async (user) => {
      //encrypt newly submitted password
      // async-await syntax
      const isMatch = await bcrypt.compare(currentPassword, user.password);

      if (isMatch) {
        console.log(user.password);
        //Update password for user with new password
        bcrypt.genSalt(10, (err, salt) =>
          bcrypt.hash(newPassword, salt, (err, hash) => {
            if (err) throw err;
            user.password = hash;
            user.save();
          })
        );
        req.flash("success_msg", "Password successfully updated!");
        res.redirect("/dashboard");
      } else {
        //Password does not match
        errors.push({ msg: "Current password is not a match." });
        res.render("changepassword", {
          errors,
          name: req.user.name,
        });
      }
    });
  }
});
router.post(“/changepassword”),确保重新验证,异步(req,res)=>{

我弄明白了那是什么。const userID应设置为等于req.user.id。然后,在我的MongooseFind中,我应该使用_id作为查询

router.post("/changepassword", ensureAuthenticated, (req, res) => {
const { currentPassword, newPassword, confirmNewPassword } = req.body;
const userID = req.user.id;
let errors = [];
//Check required fields
if (!currentPassword || !newPassword || !confirmNewPassword) {
    errors.push({ msg: "Please fill in all fields." });
}

//Check passwords match
if (newPassword !== confirmNewPassword) {
    errors.push({ msg: "New passwords do not match." });
}

//Check password length
if (newPassword.length < 6 || confirmNewPassword.length < 6) {
    errors.push({ msg: "Password should be at least six characters." });
}

if (errors.length > 0) {
    res.render("changepassword", {
        errors,
        name: req.user.name,
    });
} else {
    //VALIDATION PASSED
    //Ensure current password submitted matches
    User.findOne({ _id: userID }).then(user => {
        //encrypt newly submitted password
        bcrypt.compare(currentPassword, user.password, (err, isMatch) => {
            if (err) throw err;
            if (isMatch) {
                //Update password for user with new password
                bcrypt.genSalt(10, (err, salt) =>
                    bcrypt.hash(newPassword, salt, (err, hash) => {
                        if (err) throw err;
                        user.password = hash;
                        user.save();
                    })
                );
                req.flash("success_msg", "Password successfully updated!");
                res.redirect("/dashboard");
            } else {
                //Password does not match
                errors.push({ msg: "Current password is not a match." });
                res.render("changepassword", {
                    errors,
                    name: req.user.name,

            }
        });
