在接下来的js中,auth with react查询
告诉我,我想制作中间件来保护管理员页面,我可以通过该项目的会议授权。该项目本身在下一步。我想使用React查询来保护页面,但是我会发现错误:发生了错误:意外的令牌<在位置0中的JSON中,React查询
API:
import type { NextApiRequest, NextApiResponse } from 'next'
import { route } from 'next/dist/server/router'
import { useRouter } from 'next/router'
import checkSession from '../../src/services/checkCookie'
export async function middleware(req: NextApiRequest,res:NextApiResponse) {
if (req.method === 'GET') {
try {
const router= useRouter()
const sid = req.cookies['sid']
const admin = await checkSession(sid)
console.log(router.pathname)
// if (router.pathname === '/admin/login' || router.pathname === '/admin/regAdmin' || admin) {
// return res.next()
// }
res.send(admin)
const host = process.env.NODE_ENV === 'production' ? process.env.HOST : 'http://localhost:3000'
// return res.redirect(host + '/admin/login')
return res.send({ redirectUrl: '/admin/login' })
}catch (error) {
console.error(error)
res.status(500).send({ message: "Server error" })
}
}else{
res.status(404).send({ message: "adress error" })
}
}
API中的服务(checkSessin):
export default async function checkSession (token: string) {
// const token = req.cookies['sid']
if (typeof window === 'undefined' && token) {
const unsign = (await import('./signature')).unsign
const sessionToken = unsign(token, process.env.SECRET!)
if (sessionToken && typeof sessionToken === 'string') {
const db = (await import('../../prisma')).default
const session = db.session.findUnique({ where: { sessionToken },
include: { admin: true } })
if (session) {
return { admin: session.admin }
}
}
}
}
页面管理员:
import { NextPage } from "next"
import AdminLayout from "../../src/component/admin/AdminLayout"
import { SalesAdminComponent } from "../../src/component/admin/SalesAdmin"
import { useQuery } from 'react-query'
const AdminTable: NextPage = () => {
const { isLoading, error, data,isSuccess} = useQuery('sid', () =>
fetch('api/checkSession',{
method:'GET',
headers: {
"Content-Type": "application/json"
}
}).then(res =>res.json())
)
if (isLoading) return 'Loading...'
if (error) return 'An error has occurred: ' + error.message
return (
<>
{isSuccess &&
<AdminLayout title="OPEL Admin">
<SalesAdminComponent />
</AdminLayout>
}
{isLoading && <p>Loading..</p>}
{error && <p>Error occurred!</p>}
</>
)
}
export default AdminTable
Tell me I want to make middleware to protect the administrator pages, I have authorization through sessions on the project. The project itself is on next js . I want to use React Query to protect pages, but I get the error: An error has occurred: Unexpected token < in JSON at position 0 react query

这里发生了很多事情。响应可能是无法解释为JSON的HTML页面。请在服务器和浏览器中包括日志。
另外,您为什么使用服务器上的客户端路由器?
Lots of things are going on here. The response is probably an HTML page that cannot be parsed to JSON. Please include logs both from the server and the browser.
Also, why are you using the client router on the server?
