Giriş için POST kullanıyorum, aşağıdaki LOGIN yöntemi kodum Nodejs'i Express ve Mongoose ile kullandım
your router.js
const express = require("express");
const router = express.Router();
router.post("/login", login);
your controller.js
export.login = async(req, res) => {
//find the user based on email
const {email, password} = req.body;
try{
const user = awaitUser.findOne({email});
if(user==null)
return res.status(400).json({err : "User with
email doesnot exists.Please signup"});
}
catch(error){
return res.status(500).json({err :
error.message});
}
//IF EVERYTHING GOES FINE, ASSIGN YOUR TOKEN
make sure you have JWT installed
const token = jwt.sign({_id: user._id}, YOUR_SECRET_KEY);
res.cookie('t');
const {_id, name, email} = user;
return res.json({token, user : {_id, email, name}});
}
