Setting an Object Expiration Time (SDK for Python)

This example sets the object expiration time using a header when uploading a file stream.

import os
import traceback

from obs import ObsClient, PutObjectHeader

# Obtain an AK/SK pair using environment variables (recommended) or import it in other ways. Using hard coding may result in leakage.
# Obtain an AK/SK pair on OBS console by referring to https://support.huaweicloud.com/en-us/usermanual-ca/ca_01_0003.html.
ak = os.getenv("AccessKeyID")
sk = os.getenv("SecretAccessKey")
# Set server to the endpoint corresponding to the bucket. CN North-Beijing4 is used here as an example. Replace it with the one currently in use.
server = "https://your-endpoint"
    # Read a file stream.
    content = open('localfile', 'rb')
    bucket_name = "examplebucket"
    object_key = "objectname"
    header = PutObjectHeader()
    #Set the expiration time.
    header.expires=10
    # Upload the file stream.
    resp = obs_client.putContent(bucket_name, object_key, content,headers=header)
    # If status code 2xx is returned, the API is called successfully. Otherwise, the API call fails.
    if resp.status < 300:
        print('Put Content Succeeded')
        print('requestId:', resp.requestId)
    else:
        print('Put Content Failed')
        print('requestId:', resp.requestId)
        print('errorCode:', resp.errorCode)
        print('errorMessage:', resp.errorMessage)
except Exception:
    print(traceback.format_exc())

This example sets the object expiration time using a user-defined header when uploading a file stream.

# Obtain an AK/SK pair on OBS console by referring to https://support.huaweicloud.com/en-us/usermanual-ca/ca_01_0003.html.
ak = os.getenv("AccessKeyID")
sk = os.getenv("SecretAccessKey")
# Set server to the endpoint corresponding to the bucket. CN North-Beijing4 is used here as an example. Replace it with the one currently in use.
server = "https://your-endpoint"
obs_client = ObsClient(access_key_id=ak, secret_access_key=sk, server=server)
try:
    # Read a file stream.
    content = open('localfile', 'rb')
    bucket_name = "examplebucket"
    object_key = "objectname"
    header = PutObjectHeader()
    # Use a user-defined header to set the expiration time.
    extension_headers = {'x-obs-expires': 30}
    # Upload the file stream.
    resp = obs_client.putContent(bucket_name, object_key, content,extensionHeaders=extension_headers)
    # If status code 2xx is returned, the API is called successfully. Otherwise, the API call fails.
    if resp.status < 300:
        print('Put Content Succeeded')
        print('requestId:', resp.requestId)
    else:
        print('Put Content Failed')
        print('requestId:', resp.requestId)
        print('errorCode:', resp.errorCode)
        print('errorMessage:', resp.errorMessage)
