login.js 与我的 fetch
const loginFormHandler = async (e) => {
e.preventDefault();
const username = document.getElementById('inputUsername').value.trim();
const userPassword = document.getElementById('inputPassword').value.trim();
if (username && userPassword) {
console.log(username);
console.log(userPassword);
const res = await fetch('/api/users/login', {
method: 'POST',
body: JSON.stringify({ username, userPassword }),
headers: { 'Content-Type': 'application/json' },
})
if (res.ok) {
document.location.replace('/profile');
} else {
console.log(res.statusText);
}
}
};
userRoutes.js 和我的 POST
router.post('/login', async (req, res) => {
try {
const userData = await User.findOne({ where: { username: req.body.username } });
console.log(userData);
if (!userData) {
res
.status(400)
.json({ message: 'Incorrect username or password, please try again' });
return;
}
const validPassword = await userData.checkPassword(req.body.password);
console.log(validPassword);
if (!validPassword) {
res
.status(400)
.json({ message: 'Incorrect username or password, please try again' });
return;
}
req.session.save(() => {
req.session.user_id = userData.id;
req.session.logged_in = true;
res.json({ user: userData, message: 'You are now logged in!' });
});
} catch (err) {
res.status(400).json(err);
}
});
登录.车把
<form class="loginFormHandler">
<label for="inputUsername">Username</label>
<input type="form-input" class="form-control" id="inputUsername" />
<label for="inputPassword">Password</label>
<input type="password" class="form-control" id="inputPassword" />
<small id="passwordHelp" class="form-text text-muted">Never share
your password.</small>
<button id="login-btn" type="submit" class="btn btn-secondary btn-sm">Submit</button>
</p>
</form>
我检查了 html ID、检查了路由路径、更改了路由路径,但似乎没有任何效果。我收到 POST 400(错误请求)@login.js:10,这是获取。它确实正确地输出了我的用户名和密码。
做同样事情的另一种方法可以是...... 更改按钮类型以提交并在按钮的“onClick”上添加您的功能。
<button id="login-btn" type="button" class="btn btn-secondary btn-sm"
onclick="loginFormHandler()">
Submit
</button>
并删除
//e.preventDefault();
