Nuxt3中使用@sidebase/nuxt-auth的refresh provider时，getToken()无法获取令牌数据问题排查

我在Nuxt3的登录功能上遇到了一些问题，已经安装了@sidebase/nuxt-auth包来处理用户认证，以下是我的相关配置和代码，希望能找到getToken()返回null的原因。

1. nuxt.config.ts中的认证配置 #

auth: {
    globalAppMiddleware: true,
    baseURL: backendUrl,
    provider: {
      type: "refresh",
      endpoints: {
        signIn: { path: "/login/", method: "post" },
        signOut: { path: "/logout/", method: "get" },
        signUp: { path: "/register/", method: "post" },
        refresh: { path: "/refresh/", method: "post" },
        getSession: false,
      },
      pages: {
        login: "/login",
        register: "/register",
      },
      token: {
        signInResponseTokenPointer: "/access",
      },
      refreshToken: { signInResponseRefreshTokenPointer: "/refresh" },
    },

    enableSessionRefreshPeriodically: 5000,
    enableSessionRefreshOnWindowFocus: true,
    globalMiddlewareOptions: {
      allow404WithoutAuth: true, // Defines if the 404 page will be accessible while unauthenticated
      addDefaultCallbackUrl: "/", // Where authenticated user will be redirected to by default
    },
  },

2. 获取令牌的API代码（server/api/auth/token.get.ts） #

import { getToken } from "#auth";
export default eventHandler(async (event) => {
  const token = await getToken({ event, cookieName: "auth" });
  console.log(token);
  return token || "no token present";
});

3. 页面中打印令牌的代码 #

<script setup lang="ts">
definePageMeta({
    auth : false,
})
const headers = useRequestHeaders(['cookie'])
const {data : token} = await useFetch('/api/auth/token', {headers});
</script>
<template>
    <pre>
        {{ token }}
    </pre>
</template>

4. 用户登录逻辑代码 #

<script setup lang="ts">
definePageMeta({
  layout: "front",
  auth: {
    unauthenticatedOnly: true,
    navigateAuthenticatedTo: '/token',
  }
});

const loginWithCredentials = async () => {
    try {
      let res = await signIn(
        { ...formData },
        { callbackUrl: '/token' } // Where the user will be redirected after a successiful login
      )
      console.log(res);
    } catch (error) {
      console.log("error", error);
    } 
}
</script>

额外说明 #

• 我使用自定义后端返回包含JWT令牌的JSON数据，令牌字段为access和refresh。
• 发送POST请求到后端backEndUrl/login/并提供正确凭证时，会得到包含access和refresh字段的JSON响应。
• 我将access令牌放到JWT解析工具中验证，能正常解析出有效载荷数据。

问题 #

我期望getToken()能返回令牌的载荷数据，但实际它返回null，请问可能的问题是什么？
