我正在尝试使用everyauth 示例登录facebook。我打印了显示身份验证已成功执行的everyauth 调试消息。但是，everyauth.loggedIn 变量未设置。我不确定为什么。我实际上有这样的代码
我有一个页面，其中有 auth/facebook 的链接。当用户单击该链接时，将发送用户进行 facebook 身份验证，一切都完成了。但是，当我检查everyauth.loggedIn 它总是未定义
if(everyauth.loggedIn) {
console.log('The user has logged in');
}
以上是我在'/' url 有请求时尝试检查的内容。这是在执行 facebook 身份验证之后。但是，它总是未定义。可能是因为局部，全局变量问题。我将everyauth 变量传递给几个模块。任何建议将不胜感激
