你好，祝你有美好的一天。
我有个问题。我可以注册一个用户，但是当我登录该用户时，它会永远加载并显示：“UnhandledPromiseRejectionWarning: ReferenceError: Invalid left-hand side in assignment”
所以这是我的用户表的内容。
用户表的结构
UnhandledPromiseRejection 错误
基本上，它说我的控制器/auth.js 有问题，在第 30 行。
这是我在 auth.js 上的完整代码。
exports.signin = (req, res) => {
try {
const {email, password} = req.body;
if(!email || !password) {
return res.send("<script> alert('Provide an email and/or Password'); window.location='/signin'; </script>");
}
con.query('SELECT * FROM users WHERE email = ?', [email], async (error, results) => {
console.log(results);
if(!results || !(await bcrypt.compare(password, results[0].password))) {
return res.send("<script> alert('Email or Password is incorrect'); window.location='/signin'; </script>");
}
else {
const id = results[0].id;
const token = jwt.sign({ id }, process.env.JWT_SECRET, {
expiresIn: process.env.JWT_EXPIRES_IN
});
console.log("The token is: " + token);
const cookieOptions = {
expires: new Date(
Date.now() = process.env.JWT_COOKIE_EXPIRES * 24 * 60 * 60 * 1000
),
httpOnly: true
}
res.cookie('jwt', token, cookieOptions);
res.status(200).redirect("/profile");
}
});
}
catch(error) {
console.log(error);
}
}
exports.signup = (req, res) => {
console.log(req.body);
const {name, email, password, passwordConfirm} = req.body;
con.query('SELECT email FROM users WHERE email = ?', [email], async (error, results) => {
if(error) {
console.log(error);
}
if(results.length > 0) {
return res.send("<script> alert('This email is already in use or invalid.'); window.location='/signup'; </script>");
}
else if(password !== passwordConfirm) {
return res.send("<script> alert('Passwords do not match.'); window.location='/signup'; </script>");
}
let hashedPassword = await bcrypt.hash(password, 8);
console.log(hashedPassword);
con.query('INSERT INTO users SET ?', {name: name, email: email, password: hashedPassword}, (error, results) => {
if(error) {
console.log(error);
}
else {
console.log(results);
return res.send("<script> alert('USER IS REGISTERED! You are redirected to Sign-in Page.'); window.location='/signin'; </script>");
}
});
});
}
