Minio支持分片上传大文件,这可以提高上传速度和可靠性。分片上传的基本原理是将大文件分割成多个小块,每个小块上传到Minio服务器,最后在服务器端将这些小块组合成完整的文件。
下面是使用Minio SDK进行分片上传的基本步骤:
1. 初始化Minio客户端
```python
from minio import Minio
minio_client = Minio(endpoint="your-minio-endpoint", access_key="your-access-key", secret_key="your-secret-key", secure=False)
```
2. 开始分片上传
```python
from minio import PostPolicy
from datetime import timedelta
object_name = "your-object-name"
file_path = "path-to-your-file"
chunk_size = 1024 * 1024 * 5 # 5MB per chunk
# 初始化一个PostPolicy对象
post_policy = PostPolicy()
post_policy.set_bucket("your-bucket-name")
post_policy.set_key(object_name)
post_policy.set_content_type("application/octet-stream")
post_policy.set_content_length(os.path.getsize(file_path))
post_policy.set_expires(timedelta(days=10))
# 初始化一个新的分片上传任务
upload_id = minio_client._new_multipart_upload("your-bucket-name", object_name)
# 分片上传
with open(file_path, 'rb') as file_data:
while True:
data = file_data.read(chunk_size)
if not data:
break
part_number = minio_client._upload_part("your-bucket-name", object_name, upload_id, len(parts), data)
parts.append(part_number)
# 完成上传
minio_client._complete_multipart_upload("your-bucket-name", object_name, upload_id, parts)
```
3. 取消分片上传
如果在分片上传过程中出现错误或者需要中止上传任务,可以使用以下代码取消上传:
```python
minio_client._remove_incomplete_upload("your-bucket-name", object_name, upload_id)
```
注意:以上代码仅为示例代码,实际使用时需要根据自己的需求进行修改。
