我正在尝试将身份验证与next-auth
应用程序中的库集成。我一直在关注这里给出的官方教程https://github.com/nextauthjs/next-auth-example/。给定示例的问题是,我需要检查每个页面上是否存在需要像这样进行身份验证的会话。
import { useState, useEffect } from 'react';
import { useSession } from 'next-auth/client'
export default function Page () {
const [ session, loading ] = useSession()
// Fetch content from protected route
useEffect(()=>{
const fetchData = async () => {
const res = await fetch('/api/examples/protected')
const json = await res.json()
}
fetchData()
},[session])
// When rendering client side don't display anything until loading is complete
if (typeof window !== 'undefined' && loading) return null
// If no session exists, display access denied message
if (!session) { return <Layout><AccessDenied/></Layout> }
// If session exists, display content
return (
<Layout>
<h1>Protected Page</h1>
<p><strong>{content || "\u00a0"}</strong></p>
</Layout>
)
}
或者像这样用于服务器端检查
import { useSession, getSession } from 'next-auth/client'
import Layout from '../components/layout'
export default function Page () {
// As this page uses Server Side Rendering, the `session` will be already
// populated on render without needing to go through a loading stage.
// This is possible because of the shared context configured in `_app.js` that
// is used by `useSession()`.
const [ session, loading ] = useSession()
return (
<Layout>
<h1>Server Side Rendering</h1>
<p>
This page uses the universal <strong>getSession()</strong> method in <strong>getServerSideProps()</strong>.
</p>
<p>
Using <strong>getSession()</strong> in <strong>getServerSideProps()</strong> is the recommended approach if you need to
support Server Side Rendering with authentication.
</p>
<p>
The advantage of Server Side Rendering is this page does not require client side JavaScript.
</p>
<p>
The disadvantage of Server Side Rendering is that this page is slower to render.
</p>
</Layout>
)
}
// Export the `session` prop to use sessions with Server Side Rendering
export async function getServerSideProps(context) {
return {
props: {
session: await getSession(context)
}
}
}
这很让人头疼,因为我们需要在每个需要身份验证的页面上手动正确,有没有办法全局检查给定的路由是否是受保护的路由,如果没有登录则重定向,而不是在每个页面上都写这个?
