+
+# huaweicloud\_obs\_bucket\_object
+
+Use this data source to get info of special HuaweiCloud obs object.
+
+```hcl
+data "huaweicloud_obs_bucket_object" "object" {
+  bucket = "my-test-bucket"
+  key    = "new-key"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `bucket` - (Required) The name of the bucket to put the file in.
+
+* `key` - (Required) The name of the object once it is in the bucket.
+
+## Attributes Reference
+
+The following attributes are exported
+
+* `id` - the `key` of the resource supplied above.
+* `bucket` -  the name of the bucket to put the file in.
+* `key` - the name of the object once it is in the bucket.
+* `etag` - the ETag generated for the object (an MD5 sum of the object content).
+  When the object is encrypted on the server side, the ETag value is not the MD5 value of the object,
+  but the unique identifier calculated through the server-side encryption.
+* `size` - the size of the object in bytes.
+* `version_id` - a unique version ID value for the object, if bucket versioning is enabled.
+* `storage_class` - specifies the storage class of the object.
+* `content_type` - a standard MIME type describing the format of the object data, e.g. application/octet-stream.
+  All Valid MIME Types are valid for this input.
