Я строю социальную сеть, чтобы изучать nodejs и реагировать. В настоящее время при создании серверной части в отладке /signin
с почтальоном, я даже не могу запустить сервер узла, cmd выдает следующую ошибку:
\node_react\2\nodeapi\controllers\auth.js:40
const {_id, name, email} = user;
^
SyntaxError: Identifier 'email' has already been declared
Фрагмент кода, который выдает ошибку, следующий:
//generate a token with user id and secret
const token = jwt.sign({_id: user._id}, process.env.JWT_SECRET);
//persist the token as 't' in cookie with expiry date
res.cookie("t", token, {expire: new Date() + 9999});
//return response with user and token to frontend client
const {_id, name, email} = user;
return res.json({token, user:{_id, email, name}});
Полный код auth.js следующий:
const jwt = require("jsonwebtoken");
require ('dotenv').config();
const User = require("../models/user");
exports.signup = async (req, res) => {
const userExists = await User.findOne({email: req.body.email});
if(userExists)
return res.status(403).json({
error: "Email is taken!"
});
const user = await new User(req.body);
await user.save();
res.status(200).json({ message: "Signup success! Please login:)" });
};
exports.signin = (req,res) => {
//find the user based on email
const { email, password } = req.body
User.findOne({email}, (err, user) => {
//if error or no user
if (err || !user) {
return res.status(401).json({
error: "User with that email does not exists. Please signin."
});
}
//if user is found make sure the email and password match
// create authenticate method in model and use here
if (!user.authenticate(password))
return res.status(401).json({
error: "Email and password do not match."
});
})
//generate a token with user id and secret
const token = jwt.sign({_id: user._id}, process.env.JWT_SECRET);
//persist the token as 't' in cookie with expiry date
res.cookie("t", token, {expire: new Date() + "9999"});
//return response with user and token to frontend client
const {_id, name, email} = user;
return res.json({token, user:{_id, email, name}});
}
