unitywebrequest 上传视频

可以使用UnityWebRequest来上传视频。首先需要使用Unity的VideoPlayer组件来加载视频文件，然后将视频文件转换为字节数组，最后使用UnityWebRequest上传字节数组即可。

以下是一个简单的示例代码：

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Video;

public class VideoUploader : MonoBehaviour
{
    public string uploadUrl;
    public VideoPlayer videoPlayer;

    public void UploadVideo()
    {
        StartCoroutine(Upload());
    }

    private IEnumerator Upload()
    {
        // Load video file
        videoPlayer.Prepare();
        while (!videoPlayer.isPrepared)
        {
            yield return null;
        }
        byte[] videoBytes = System.IO.File.ReadAllBytes(videoPlayer.url);

        // Upload video file
        UnityWebRequest request = UnityWebRequest.Put(uploadUrl, videoBytes);
        yield return request.SendWebRequest();

        if (request.result == UnityWebRequest.Result.Success)
        {
            Debug.Log("Video upload successful!");
        }
        else
        {
            Debug.LogError("Video upload failed: " + request.error);
        }
    }
}

在上面的示例代码中，我们首先使用VideoPlayer组件加载视频文件，然后将视频文件转换为字节数组。接着，我们使用UnityWebRequest来上传字节数组。最后，我们检查上传结果并输出日志信息。
