--description--
无论是否登录,或者哪怕用户试图访问其他页面,目前都会跳转到 /profile
。为了解决这个问题,我们需要在 profile 页面渲染之前进行用户验证,创建中间件就可以实现这个功能。
这个挑战的目标是创建ensureAuthenticated(req, res, next)
中间件方法,通过在 request 上调用 passports 的isAuthenticated
方法,我们可以检查 req.user 是否定义,从而确定用户是否通过认证。如果用户已通过验证,就会调用 next(),否则我们应重定向到主页并让用户登录。该中间件的实现如下:
function ensureAuthenticated(req, res, next) {
if (req.isAuthenticated()) {
return next();
}
res.redirect('/');
};
然后,我们需要把 ensureAuthenticated 中间件添加到处理请求的回调之前:
app
.route('/profile')
.get(ensureAuthenticated, (req,res) => {
res.render(process.cwd() + '/views/pug/profile');
});
完成上述要求后,你可以在下方提交你的页面链接。如果你遇到了问题,可以参考 这里 的答案。
--hints--
ensureAuthenticated
中间件应添加到 /profile
路由中。
(getUserInput) =>
$.get(getUserInput('url') + '/_api/server.js').then(
(data) => {
assert.match(
data,
/ensureAuthenticated[^]*req.isAuthenticated/gi,
'Your ensureAuthenticated middleware should be defined and utilize the req.isAuthenticated function'
);
assert.match(
data,
/profile[^]*get[^]*ensureAuthenticated/gi,
'Your ensureAuthenticated middleware should be attached to the /profile route'
);
},
(xhr) => {
throw new Error(xhr.statusText);
}
);
如果没有通过验证,对 /profile 的 GET 请求应重定向到 /
(getUserInput) =>
$.get(getUserInput('url') + '/profile').then(
(data) => {
assert.match(
data,
/Home page/gi,
'An attempt to go to the profile at this point should redirect to the homepage since we are not logged in'
);
},
(xhr) => {
throw new Error(xhr.statusText);
}
);
