问题描述
上传视频 (.mp4) 文件后,S3 元数据设置其Content-Type : binary/octet-stream 当我的浏览器强制下载文件而不是播放为了让它在浏览器中播放我需要改变那个内容类型以编程方式转换为 django
中的“video/mp4”解决方法
在花了很多时间之后,我找到了解决方案: {
def presign_post_S3_url(self,key=None,is_public=False):
acl = 'private'
if is_public:
acl = 'public-read'
fields = {"acl": acl,"Content-Type": "video/mp4"}
conditions = [
{"acl": acl},["starts-with","$Content-Type",""]
]
if key is None:
return ""
##s3_client is boto3.client object
s3_client = self.get_s3_client()
if s3_client is None:
return ""
data = s3_client.generate_presigned_post(
Bucket=self.bucket,Key=key,Fields=fields,Conditions=conditions
)
return data
