xamarin.forms - Xamarin 表单 - Xamarin.Social

Question

我目前在 xamarin 表单中使用 Xamarin.Social 组件，当我尝试发布到 Facebook 时，它给我一个错误说明：共享错误：远程服务器返回错误：（403）禁止“，任何人都知道我为什么会得到这个错误以及如何解决它？Twitter 发布也非常好，所以它只是 Facebook。

谢谢你

some Troubleshooting for your issue:

1. You probably already have your ClientID correctly set up. Check it again on https://developers.facebook.com/apps

2. It took me a while to figure out what to enter as for the RedirectURL. At the moment i am using https://apps.facebook.com/yourappname/. If this is not working for you, go to your App on Facebook Developers Page > Settings > Add Platform > Facebook Canvas > And enter this url as for the "Canvas Page". Authentication should work fine now, and the 403 error should no longer occur.

My working example, for creating the Facebook service:

    public static FacebookService Facebook
    {
        get
        {
            if (mFacebook == null)
            {
                mFacebook = new FacebookService() {
                    ClientId = "<Your App ID from https://developers.facebook.com/apps>",
                    RedirectUrl = new Uri ("https://apps.facebook.com/yourappname/")
                };
            }

            return mFacebook;
        }
    }

For which Platform are you developing? The rest of the share process is just like in the Xamarin.Social IOS Unified sample. Don‘t hesitate to ask for clarification.
