使用nuxt跟eggjs做的服务端渲染，目前遇到问题了，在about页面刷新，eggjs的中间件拿不到用户的session了，哪位大佬帮看看，不知道是nuxt这边的问题还是eggjs这边的问题

实例地址

中间件定义

const { Nuxt, Builder } = require("nuxt");
let config = require("../../nuxt.config");
module.exports = (options, app) => {
  const nuxtRender = new Nuxt(config);
  let isDev = process.env.NODE_ENV !== "production";
  if (isDev) {
    new Builder(nuxtRender).build();
  }
  return async function(ctx, next) {
    let flag = false;
    let routerArr = [];
    if (!flag) {
      routerArr = app.router.stack.map(el => el.path);
      flag = true;
    }
    if (routerArr.some(el => el === ctx.path)) {
      return await next();
    }
    ctx.status = 200;
    ctx.req.session = ctx.session;
    const { res, req } = ctx;
    return new Promise((resolve, reject) => {
      ctx.res.on("close", resolve);
      ctx.res.on("finish", resolve);
      nuxtRender.render(req, res, promise => {
        promise.then(resolve).catch(reject);
      });
    });
  };
};

about页面请求

export default {
  asyncData({ params }) {
    return axios.get("http://127.0.0.1:7001/api/info").then(res => {
      return { info: res.data };
    });
  }
};

nuxtServerInit定义

export const state = () => ({
  user: null
});

export const mutations = {
  setUser(state, data) {
    state.user = data;
  }
};
export const actions = {
  nuxtServerInit({ commit }, { req }) {
    if (req.session.user) {
      console.log("client", req.session.user);
      commit("setUser", req.session.user);
    }
  }
};
