# 以下代码展示了如何获取对象元数据的用法

# 首先初始化AccessKeyId、AccessKeySecret、Endpoint等信息。
# 通过环境变量获取，或者把诸如“<你的AccessKeyId>”替换成真实的AccessKeyId等。
access_key_id = os.getenv('OSS_TEST_ACCESS_KEY_ID', '<你的AccessKeyId>')
access_key_secret = os.getenv('OSS_TEST_ACCESS_KEY_SECRET', '<你的AccessKeySecret>')
bucket_name = os.getenv('OSS_TEST_BUCKET', '<你的Bucket>')
endpoint = os.getenv('OSS_TEST_ENDPOINT', '<你的访问域名>')

# 确认上面的参数都填写正确了
for param in (access_key_id, access_key_secret, bucket_name, endpoint):
assert '<' not in param, '请设置参数：' + param

# 创建Bucket对象，所有Object相关的接口都可以通过Bucket对象来进行
bucket = oss2.Bucket(oss2.Auth(access_key_id, access_key_secret), endpoint, bucket_name)

object_meta = bucket.get_object_meta('你的对象名')

# 查看对象元数据信息
print(object_meta.headers['Last-Modified'])
print(object_meta.headers['Date'])
print(object_meta.headers['ETag'])
