所以我的问题是,当我验证用户凭据时,login()的承诺还没有解决。因此,loginResult将为Promise {}。我知道我需要以某种方式等待结果,但是无论如何我还是可以想到的。
任何提示都值得赞赏。这是用于学校项目的,所以请不要对这有多不安全感指责我。
var express = require('express');
var router = express.Router();
var login = require('../controller/authenticate/login');
/* GET users listing. */
router.get('/', function (req, res, next) {
res.send('respond with a resource');
});
/* Login user */
router.post('/login', function (req, res, next) {
const username = req.body.username;
// This is a async return so its not working right. Currently only reading Promise{<pending>}
let loginResult = login(username, req.body.password);
console.log(loginResult)
if (loginResult === true) {
res.render('users', {username: username});
}
else {
res.render('index', {error: true});
}
});
module.exports = router;
答案 0 :(得分:1)
喜欢吗?
在函数前添加async
,然后await
:
router.post('/login', async function (req, res, next) {
const username = req.body.username;
const loginResult = await login(username, req.body.password);
console.log(loginResult)
if (loginResult === true) {
res.render('users', {username: username});
} else {
res.render('index', {error: true});
}
});
或使用Promises和then
:
router.post('/login', function (req, res, next) {
const username = req.body.username;
login(username, req.body.password)
.then(resp => {
console.log(resp)
if (resp === true) {
res.render('users', {username: username});
} else {
res.render('index', {error: true});
}
});
});
