Facebook c# sdk 错误 OAuthException - #2

Question

我正尝试在我的 Facebook 页面上发布 post，但收到此错误消息

(OAuthException - #2) An unexpected error has occurred. Please retry your request later.

  FacebookClient app = new FacebookClient(accesstoken);
      
      var result = app.Post("/" + model.pageId + "/feed", messagePost);

Answer 1

dynamic messagePost = new ExpandoObject();
            //messagePost.access_token="accesstoken";
            messagePost.picture = "https://miro.medium.com/max/1200/1*mk16aYaf_Bes1E3Imhc0A.jpeg";
            messagePost.link = "https://exemple.com/";
            //messagePost.name = model.titre;
            //messagePost.caption = "this post was created by my website";
            messagePost.message = "test_message";


FacebookClient app = new FacebookClient(accesstoken);
      
      var result = app.Post("/" + model.pageId + "/feed", messagePost);

问题是我给 facebook 访问令牌 2 次，这让 facebook 很困惑 api 我刚刚删除了 messagePost.access_token，它工作正常
