问题描述
我正在尝试开发一个模块,以通过Python的MinIO API上传视频文件。
该文件可以上传到MinIO,但是无法通过url进行查看,例如:http:// localhost:9000 / lms-videos / video / output.mp4。另外,通过MinIO上传的文件应为19.39Mb,通过API上传的文件应为25 + MB,不知道是什么原因.....
以下是我的代码的一部分:
# minio client
@api.model
def _get_minio_client(self):
host = '192.168.1.102:9000'
access_key = 'minioadmin'
secret_key = 'minioadmin'
if not all((host,access_key,secret_key)):
raise exceptions.UserError('Incorrect configuration of MinIO')
return Minio(
host,access_key = access_key,secret_key = secret_key,secure = False
)
# upload
@api.model
def _store_file_write(self):
client = self._get_minio_client()
bin_data = self.datas_minio
fname = "output_test"
#client.put_object('lms-videos','videos/'+ fname + '.mp4',io.BytesIO(self.datas_minio),len(bin_data),'video/mp4')
with io.BytesIO(self.datas_minio) as bin_data_io:
client.put_object('lms-videos',bin_data_io,'video/mp4')
@api.depends('document_id','slide_type','mime_type','external_url')
def _compute_embed_code(self):
res = super(Slide,self)._compute_embed_code()
for record in self:
if record.slide_type == 'miniovideo':
self._store_file_write()
content_url = 'http://localhost:9000/lms-videos/videos/' + record.name + '.mp4'
record.embed_code = '<video class="miniovideo" controls controlsList="nodownload"><source src="' + content_url + '" type=MPEG-4/></video>'
@api.onchange('datas_minio')
def _on_change_datas(self):
res = super(Slide,self)._on_change_datas()
if self.datas_minio:
#fname = self.datas_minio.decode("utf-8")
#bin_data = self.datas_minio
self._store_file_write()
#self._get_minio_client().put_object('lms-videos','/videos/'+ fname + '.mp4',io.BytesIO(bin_data),'video/mp4')
return res
解决方法
通过添加b64decode解决的问题
@api.model
def _store_file_write(self):
client = self._get_minio_client()
bin_data = base64.b64decode(self.datas_minio)
fsize = len(bin_data)
fname = "output_test"
with io.BytesIO(bin_data) as bin_data_io:
client.put_object('lms-videos',#'videos/'+ fname + '.mp4','videos/output_test.mp4',bin_data_io,fsize,'video/mp4')
