如何使用 Facebook 图形 API 将多个视频和照片附加到状态帖子

Question

我正在尝试通过 Facebook Graph API 发布包含多个附加视频和照片的帖子。我首先使用批处理请求上传了视频和照片，并成功获取了上传媒体的 ID。然后我使用 attach_media 将媒体 ID 与发布数据一起传递。单张或多张照片都可以正常工作。但不适用于单个视频或多个视频。我收到此错误：“图表返回错误：(#10) 应用程序没有执行此操作的权限”，只要视频的 id 包含在 attach_media 中。

我知道，作为用户，您可以将多个视频和照片附加到 Facebook 帖子中。 Facebook Graph API 是否完全不支持多个视频？

我正在使用 C# 和 Unity

这是上传视频然后发送带有附加结果视频ID的帖子的功能：

private IEnumerator UploadMediaWithStatus(string message, string[] mediaUrls)
{
    FacebookPostStatusUpdatedEvent.Invoke("Submitting FB post ... ");

    var curPage = m_UserPages[FacebookFeedsList.GetInstance().ActiveFeed] as IDictionary<string, object>;
    var fbClient = new FacebookClient(curPage["access_token"].ToString());

    List<string> mediaIDs = new List<string> ();
    foreach (string mediaUrl in mediaUrls) 
    {
        WWW _media = new WWW("file://" + mediaUrl);
        yield return _media;            

        if (!System.String.IsNullOrEmpty(_media.error))
        {
            FacebookPostStatusUpdatedEvent.Invoke("FB post failed: error loading media " + mediaUrl);
            //TruLogger.LogError("cant load Image : " + _image.error);
            yield break;
        }

        byte[] mediaData = null;
        FacebookMediaObject medObj = new FacebookMediaObject();
        JsonObject p = new JsonObject();

        mediaData = _media.bytes;
        medObj.SetValue(mediaData);
        medObj.FileName = "InteractiveConsole.mp4";
        medObj.ContentType = "multipart/form-data";
        p.Add("description", message);
        p.Add("source", medObj);

        uploadedImgID = "";

        fbClient.PostCompleted +=  OnPostImageUploadComplete;
        fbClient.PostAsync("/me/videos", p);


        //wait for image upload status and hopefully it returned a media ID on successful image upload
        while (uploadedImgID == "") 
        {
            //if image updload failed because of rate limit failure we can just abort rest  of this
            if (rateLimitErrorOccurred) 
            {
                rateLimitErrorOccurred = false;
                yield break;
            }
            yield return true;
        }

        //if video uploaded succesfully
        if (uploadedImgID != null) 
        {
            mediaIDs.Add (uploadedImgID);

            var response = (JsonObject)fbClient.Get("/" + uploadedImgID + "?fields=status,published");
            TruLogger.LogError("Video Status Details: " + response.ToString());
            string vidStatus = (response["status"] as IDictionary<string, object>)["video_status"] as string;
            while( vidStatus != "ready")
            {
                yield return new WaitForSeconds(5.0f);
                response = (JsonObject)fbClient.Get("/" + uploadedImgID + "?fields=status,published");
                TruLogger.LogError("Video Status Details: " + response.ToString());
                vidStatus = (response["status"] as IDictionary<string, object>)["video_status"] as string;          
            }
            TruLogger.LogError("Video ready");
            yield return new WaitForSeconds(5.0f);
        }
    }

    if (mediaIDs.Count > 0) 
    {
        curPage = m_UserPages[FacebookFeedsList.GetInstance().ActiveFeed] as IDictionary<string, object>;
        fbClient = new FacebookClient(curPage["access_token"].ToString());
        JsonObject p = new JsonObject();
        p.Add("message", message);

        for (int i = 0; i < mediaIDs.Count; i++) 
        {
            p.Add ("attached_media["+ i + "]", "{\"media_fbid\":\"" + mediaIDs[i] + "\"}");
        }

        fbClient.PostCompleted += OnPostUploadComplete;
        fbClient.PostAsync("/me/feed", p);          
    }

Facebook 不允许在业务页面上直接上传多个视频或带有视频的照片。但是，可以在个人页面上作为替代解决方案，您可以在个人页面上创建帖子并在企业页面上分享。
