next.js - Next Auth 自定义提供商 OIDC 随机数检查

Question

我正在使用需要随机数的 IDP 我的 nextauth 是这样的(请注意，我在授权步骤中通过了我的随机数):

import NextAuth, { NextAuthOptions } from 'next-auth'

const randomString = (length: number) => {
    let text = ''
    let possible =
        'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'
    for (let i = 0; i < length; i++) {
        text += possible.charAt(Math.floor(Math.random() * possible.length))
    }
    return text
}
const nonce = `nonce${randomString(32)}`
const authOptions: NextAuthOptions = {
    providers: [
        {
            issuer: 'https://fcp.integ01.dev-franceconnect.fr',
            id: 'franceconnect',
            clientSecret: process.env.FRANCE_CONNECT_SECRET || 'undefined',
            clientId: process.env.FRANCE_CONNECT_ID || 'undefined',
            name: 'FranceConnect',
            type: 'oauth',
            idToken: true,
            client: {
                authorization_signed_response_alg: 'HS256',
                id_token_signed_response_alg: 'HS256'
            },
            authorization: {
                url: 'https://fcp.integ01.dev-franceconnect.fr/api/v1/authorize',
                params: {
                    scope: 'openid given_name gender',
                    nonce,
                    redirect_uri: `http://localhost:3000/api/auth/callback/franceconnect`,
                },
            },
            token:`https://fcp.integ01.dev-franceconnect.fr/api/v1/token`,                    
            userinfo:
                'https://fcp.integ01.dev-franceconnect.fr/api/v1/userinfo',
            profile(profile) {
                console.log(profile)
                return profile
            },
        },
    ],
    debug: true,
    secret: 'hdh-secret',
    callbacks: {
        async jwt({ token, account }) {
            return token
        },
        async session({ session, token, user }) {
            return session
        },
    },
}

export default NextAuth(authOptions)

我遇到了这个错误:

[next-auth][error][CALLBACK_OAUTH_ERROR]

}

如果我删除 nonce，我会从 IDP 收到此错误:{"status":"fail","message":"以下字段丢失或为空:nonce"} 我该如何告诉下一个身份验证使用随机数？

我设法通过自己执行 token 和用户信息请求(感谢请求方法)来使其工作。 这是最终的代码:

providers: [
    {
        issuer: 'https://fcp.integ01.dev-franceconnect.fr',
        id: 'franceconnect',
        clientSecret: process.env.FRANCE_CONNECT_SECRET || 'undefined',
        clientId: process.env.FRANCE_CONNECT_ID || 'undefined',
        name: 'FranceConnect',
        type: 'oauth',
        authorization: {
            url: 'https://fcp.integ01.dev-franceconnect.fr/api/v1/authorize',
            params: {
                scope: 'openid profile email',
                nonce,
                redirect_uri: `${process.env.NEXTAUTH_URL}/api/auth/callback/franceconnect`,
            },
        },
        token: {
            async request(context) {
                const body = {
                    grant_type: 'authorization_code',
                    redirect_uri: `${process.env.NEXTAUTH_URL}/api/auth/callback/franceconnect`,
                    client_id: process.env.FRANCE_CONNECT_ID || 'undefined',
                    client_secret:

                    code: context.params.code || 'undefined',
                }
                const data = new URLSearchParams(body).toString()
                try {
                    const r = await axios({
                        method: 'POST',
                        headers: {

                                'application/x-www-form-urlencoded',
                        },
                        data,
                        url: `https://fcp.integ01.dev-franceconnect.fr/api/v1/token`,
                    })
                    return { tokens: r.data }
                } catch (err: any) {
                    console.error(err)
                    throw new Error(err)
                }
            },
        },
        userinfo: {
            url: 'https://fcp.integ01.dev-franceconnect.fr/api/v1/userinfo',
            params: { schema: 'openid' },
            async request(context) {
                const r = await axios({

                    url: 'https://fcp.integ01.dev-franceconnect.fr/api/v1/userinfo?schema=openid',
                    headers: {
                        Authorization: `Bearer ${context.tokens.access_token}`,
                    },
                })
                return r.data
            },
        },
        profile(profile) {
            return {
                ...profile,
