如何使用 Django 在 Amazon S3 中存储图像文件，在 Vimeo 中存储视频

Question

我想在我的 django 项目中将图像文件存储在 S3 中，将视频文件存储在 Vimeo 中。我是 Django-storage 的 S3Boto3Storage 作为存储后端。由于 Vimeo 负责视频文件的压缩和内容交付，而且与 S3 相比它便宜，我想将它用于视频文件。

我想过使用django模型FileField中的upload_to属性将文件上传到Vimeo，但是我无法获取视频文件的绝对路径方法。

这里是我对upload_to方法的实现，

import vimeo


def vimeo_client():
    client = vimeo.VimeoClient(
        token=settings.VIMEO_ACCESS_TOKEN,
        key=settings.VIMEO_CLIENT_ID,
        secret=settings.VIMEO_CLIENT_SECRET
    )
    return client

def get_media_path(instance, filename):
    new_filename = '{}.{}'.format(uuid.uuid4(), filename.split('.')[-1])
    if instance.type == 'image':
        file_path = 'posts/media/images/{filename}'.format(
            filename=new_filename)
    else:
        client = vimeo_client()
        file_path = client.upload(
            filename,
            data={
                'name': instance.title,
                'description': instance.description
            }
        )
    logger.info("File uploaded to: [{}]".format(file_path))
    return file_path

但是它给我这个错误

OSError: [Errno 2] No such file or directory: 'videoplayback.mp4'

或者我可以根据自己的目的自定义 S3Boto3Storage。我想知道什么是更好的解决方案。

编辑这是完整的堆栈跟踪

Vimeo API 支持讨论的 3 种视频上传策略 here。 tus 方法假设视频文件在本地系统中。要从浏览器上传视频，需要使用 form-based uploads 方法，这对仅 API 的服务器没有用。有两种选择可以解决这个问题，

Upload the video from the client-side to the API server using your own API endpoint and then use vimeo.py to upload it to the Vimeo and delete the actual video file from the server.

Use vimeo.js to upload the video file from the client side and then store the returned video_uri in the backend.
