Facebook 如何访问uid+；FB.Event.subscribe之外的accesstoken？
我成功地运行了FB.Event.subscribe，并且可以从该函数中输出Facebook 如何访问uid+；FB.Event.subscribe之外的accesstoken？,facebook,facebook-graph-api,facebook-javascript-sdk,Facebook,Facebook Graph Api,Facebook Javascript Sdk,我成功地运行了FB.Event.subscribe，并且可以从该函数中输出uid和accesstoken——但是我想知道如何从基本上任何地方访问uid和accesstoken 我最初的想法是，我需要在函数之外声明一个全局uid和accesstoken变量，但是到目前为止我还没有这样做，当我试图输出全局变量时，我只得到了未定义的 我的代码就在启动标记之后： <body> <div id="fb-root"></div> <script> //Decl

您还可以通过FB.getUserID（）检索uid，这是因为JS SDK是异步工作的–当您尝试访问它时，数据尚未到达。一旦回调函数将值分配给变量，您就可以“从任何地方”访问它们，但之前不能。嗨，cbroe，非常感谢您的评论。您是否有任何机会对一种方法有任何建议，以便在我尝试在我发布的代码范围内访问它之前，能够等待它被设置？
