facebook - "authResponse"参数在 FB.init() 中有什么作用？

Question

FB.init() 文档说明你可以通过一些神秘的 authResponse它的参数是 Object also retrievable by getAuthResponse .它具体有什么作用？

Answer 1

好问题。尽管 FB 在这方面的文档很少，a blog post解释了正在发生的事情。在 FB.init 中启用 oauth 后，FB.login 将使用包含 authResponse 的响应对象进行响应，该对象显然可以由应用程序存储并在后续应用程序访问 FB.init 时安装。

具体来说，我引用了 same post :

As with sessions, an authorization record can be installed when FB.init is called by including an authResponse parameter and attaching it to a valid authorization response for the logged in user. Whereas many developers would store sessions in a database, you might now store authorization responses instead.
