“表示会话的未定义的resave选项；提供resave选项node_modules/admin-bro-expressjs/plugin.js:138:14”

Question

在我的管理中使用admin，它可以正常工作，直到我尝试使用它的身份验证，当我尝试使用admin登录表单仪表板登录到管理员时，它只是一直加载没有响应，我的终端说。

会话取消推荐的未定义的resave选项；提供resave选项node_modules/admin-bro-expressjs/plugin.js:138:14

快捷会话不建议使用未定义的saveUninitialized选项；提供saveUninitialized选项node_modules/AdminBro/plugin.js :138:14 AdminBro: bundle就绪，我们连接到了！

AdminBro.registerAdapter(AdminBroMongoose);

const adminBro = new AdminBro({

  rootPath: '/admin',
});

const ADMIN = {
  email: process.env.ADMIN_EMAIL || 'admin@example.com',
  password: process.env.ADMIN_PASSWORD || 'lovejs',
}

const router = AdminBroExpress.buildAuthenticatedRouter(adminBro, {
    cookieName: process.env.ADMIN_COOKIE_NAME || 'admin-bro',
    cookiePassword: process.env.ADMIN_COOKIE_PASS || 'some-super-sensitive-password',
    authenticate: async (email, password) => {
    if (ADMIN.password === password && ADMIN.email === email) {
      return ADMIN
    }
    return null

    }
});

module.exports = router;

如能提供任何帮助，将不胜感激。

Answer 1

把你的app.use('/admin', adminRouter);放在app.use(express.json());之前

这就是我如何解决这个问题的原因，因为admin与解析器或内置的解析器有一个问题。

Answer 2

删除app.use(express.urlencoded({ extended: true }));
