使用Django和python將視頻上傳到Amazon S3

Question

我正在嘗試的只是將視頻上傳到Amazon s3，而不是像Django那樣定期保存在媒體中。 因此創建了一個下面的模型

def upload_to_amazon_s3(instance, filename):
    aws_access_key_id = settings.AWS_ACCESS_KEY_ID
    aws_secret_access_key = settings.AWS_SECRET_ACCESS_KEY

    file_name = 'videos/{0}_{1}/{2}'.format(instance.user.id, instance.user.username, filename)

    conn = boto.connect_s3(aws_access_key_id, aws_secret_access_key)
    try:
        bucket = conn.get_bucket("ipitch_videos", validate=True)
    except S3ResponseError:
        bucket = conn.create_bucket('ipitch_videos')

    #Get the Key object of the bucket
    k = Key(bucket)
    #Crete a new key with id as the name of the file
    k.key=file_name

    #Upload the file
    result = k.set_contents_from_file(instance.video_file)

    # we need to make it public so it can be accessed publicly
    # using a URL like http://s3.amazonaws.com/bucket_name/key
    k.make_public()

    get_s3_obj = Key(bucket,file_name)
    endpoint_url = get_s3_obj.generate_url(expires_in=0, query_auth=False)
    return endpoint_url

class Video(DateTimeModel):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    name = models.CharField(max_length=255)
    video_file = models.FileField(upload_to=upload_to_amazon_s3)

我正在從Amazon s3 Url獲取endpoint_url值，例如https://ipitch_videos.s3.amazonaws.com/videos/1_username/super.mpg

因此，當我從前端表單或具有所有字段user, name, video_file的API上傳視頻時，一條記錄已成功創建到數據庫中，但是會發生以下三個問題

1. 視頻記錄實例正在保存，但在來自亞馬遜的endpoint_url https：//之后分割/ ，並且僅使用https:/而不是https:// ，如下所示

2. 隨着亞馬遜的上傳過程，一個視頻文件也在本地創建，其路徑來自endpoint_url，例如，如果終點URL為https://ipitch_videos.s3.amazonaws.com/videos/1_username/super.mpg django正在如下媒體下創建以下文件夾

那么如何避免django也在本地創建視頻文件呢？

Answer 1

您可以使用S3BotoStorage。

$ pip install django-storages boto將'storages'添加到INSTALLED_APPS：

INSTALLED_APPS = (
      ...,
      'storages',
 )

添加另一個存儲類：

class MediaStorage(S3BotoStorage):
    location = settings.MEDIAFILES_LOCATION

並在settings.py中：

MEDIAFILES_LOCATION = 'media'
MEDIA_URL = "https://%s/%s/" % (AWS_S3_CUSTOM_DOMAIN, MEDIAFILES_LOCATION)
DEFAULT_FILE_STORAGE = 'custom_storages.MediaStorage'
