使用临时token上传阿里oss，是否可以考虑支持一下，或者有其他什么方案可以使用的？

附Python实现方式

```python
import oss2

access_key_id = '<ACCESS_KEY_ID>'
access_key_secret = '<ACCESS_KEY_SECRET>'
security_token = '<SECURITY_TOKEN>'
endpoint = '<ENDPOINT 不带http://的>'  # 根据你的Bucket所在的区域更改
bucket_name = '<BUCKET_NAME>'
object_name = '<OBJECT_NAME>'
local_file_path = '<LOCAL_FILE_PATH>'


# 使用临时访问凭证中的认证信息初始化StsAuth实例
auth = oss2.StsAuth(access_key_id, access_key_secret, security_token)
bucket = oss2.Bucket(auth=auth, endpoint=endpoint, bucket_name=bucket_name, connect_timeout=30)

with open(local_file_path, 'rb') as f:
    file_steam = f.read()
bucket.put_object(object_name, file_steam, headers={'Content-Type': 'image/jpg'})
print(bucket.sign_url('GET', object_name, 100))
```
