经过大量搜索从桌面应用程序使用 facebook 登录后，我使用 DJ Native swing 浏览器创建了自己。

但我仍然有一个问题需要更改。

我正在使用 Enabled Browser Swing 使用 facebook 登录。当我登录 Facebook 时，我得到一个权限框，它正在请求用户权限。但我不想显示那个框。是否可以在 Facebook 中自动授予权限。

我只想删除此警告对话框并自动授予权限，那么我该怎么做呢？

欢迎任何建议。

最佳答案

好吧，我只是通过删除一些参数来解决它，比如我制作 URL

 public static String firstRequest = "https://graph.facebook.com/oauth/authorize?"
            + "client_id="
            + API_KEY
            + "&redirect_uri=http://www.facebook.com/connect/login_success.html&"
            + "scope=email,offline_access";

它只是按我的意愿只询问一次 :)

这里是相同的示例。
