as3-facebook-api（用于flash）的Facebook.init方法允许使用可选的accessstoken参数。
但.init（...）方法的重点是，初始化一切...... accessstokens是init阶段的副产品。
那么如何才能在第一时间进行访问。
（请不要回答一个修辞的答案......我正在寻找一个应用实用的答案......谢谢）。

访问令牌在特定时间内有效，因此从技术上讲，您可以重复使用它。那，或者你可以使用另一种语言连接到Facebook，并从中获得一个令牌（比你想象的更常见）

好的，在运行一些测试并查看Facebook AS3中的代码之后，这就是我所拥有的：
Object status = false init()，因此Facebook.init( APP_ID, this._onInit, {status:false}, myAccessToken);来电变为getLoginStatus() ）init()外部事件，所以你节省了几个电话，你的程序启动得更快 - 就我所知，这就是它。 ?access_token=[myToken]，只需在调用{{{{}}时将api()附加到您的网址末尾1}}（例如Facebook.api( "/me?access_token=" + myAccessToken, this._onInfo );） - 或完全跳过lib，只需向网址发出URLLoader个请求显示所有这些的简单示例。正常创建您的应用，替换您的应用ID，并正常连接。它会找出你的uid和访问令牌。复制令牌，再次启动应用程序，然后将令牌粘贴到输入区域。现在，当您再次init()时，它会使用此功能。
