我试图通过Facebook Graph API发布包含多个附加视频和照片的帖子。我首先使用批量请求上传视频和照片，并成功获取上传媒体的ID。然后我使用attached_media传递媒体ID和帖子数据。单张或多张照片的效果很好。但不适用于单个视频或多个视频。我收到此错误：＆＃34; Graph返回错误：（＃10）应用程序没有此操作的权限＆＃34;只要视频的ID包含在attached_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。对于多个视频，Facebook Graph API是否不支持此功能？
我正在使用C＃和Unity
以下是上传视频然后发送附有结果视频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>;

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;

{
yield return new WaitForSeconds(5.0f);

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，您可以在个人页面上创建帖子，作为替代解决方案，您可以在个人页面上创建帖子并在业务页面上共享。
