Tweetinvi块上传，用于大型上传

Question

我正在尝试使用tweetinvi.file上传图像上传的上传，但相同的代码对视频不起作用(大型视频超过20 MB(

我在这里问，但是现在答案

tweetinvi大型视频上传失败，null参考

所以我寻找另一个解决方案。我对此进行了编码，但是它不起作用，它没有错误，但它不起作用

  if (file.ContentType.Contains("video"))//video
                        {
                            var video1 = System.IO.File.ReadAllBytes(path);
                            var chunk = Upload.CreateChunkedUploader(); //Create an instance of the ChunkedUploader class (I believe this is the only way to get this object)
                            using (FileStream fs = System.IO.File.OpenRead(path))
                            {
                                chunk.Init("video/mp4", (int)fs.Length); //Important! When initialized correctly, your "chunk" object will now have a type long "MediaId"
                                byte[] buffer = new byte[video1.Length]; //Your chunk MUST be 5MB or less or else the Append function will fail silently.
                                int bytesRead = 0;
                                while ((bytesRead = fs.Read(buffer, 0, buffer.Length)) > 0)
                                {
                                    byte[] copy = new byte[bytesRead];
                                    Buffer.BlockCopy(buffer, 0, copy, 0, bytesRead);
                                    TimeSpan s = new TimeSpan();
                                    chunk.Append(copy, chunk.NextSegmentIndex.ToString()); //The library says the NextSegment Parameter is optional, however I wasn't able to get it to work if I left it out. 
                                }
                            }
                            var video = chunk.Complete(); //This tells the API that we are done uploading.
                            listMedia.Add(video); 

                        }

我想说，在处理您的错误后，我能够确定您遇到的问题。

问题是您没有指定上传的media_category。

除此之外，您还需要等待Twitter处理媒体。

在Tweetinvi 2.1中，应该使该过程更容易。请使用以下代码：

var binary = File.ReadAllBytes(@"video_path");
var media = Upload.UploadVideo(binary);
// The upload is completed but it does not mean it succeeded!
if (!media.HasBeenUploaded)
{
    // Something went wrong during the upload. 
    // Please retry or check the video type/settings.
    return;
}
// Just wait for Twitter to have processed the upload (RECOMMENDED)
Upload.WaitForMediaProcessingToGetAllMetadata(media);
// Now the media is ready to be used in a Tweet
var tweet = Tweet.PublishTweet("hello", new PublishTweetOptionalParameters
{
    Medias = { media }
});

您可以在更新的文档中阅读有关上传的更多信息：https：//github.com/linvi/tweetinvi/wiki/wiki/upload#upload-status-video

最后，请注意，计划2.2和2.3的上传进一步改进。

祝您有美好的一天，感谢您报告此问题，
