Downloading an Object
Function
This API is used to download an object from OBS to a local directory. For more information, see Downloading an Object.
Working with Other Functions
If the object uploaded to the server is encrypted on the server using the encryption key provided by the client, downloading the object requires including the encryption key in the message.
By default, the GET operation returns the current version of an object. If the current version of the object is a delete marker, OBS returns a code meaning that the object does not exist. To obtain an object of a specified version, the versionId parameter can be used to specify the desired version.
Archive or Deep Archive Objects
If the object you want to download is in the Archive or Deep Archive storage class, ensure that this object has been restored before you download it. The response varies depending on the object's restore state. If an object has been restored, the x-obs-restore header (indicating the expiry date of the object) is returned when the object is successfully downloaded. If you send a request to download Archive or Deep Archive objects that have not been restored or are being restored, a 403 Forbidden error will be returned.
Constraints
Authorization
To call this API, you must be the object owner or have the permissions to download an object. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.
- If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
- If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you must have the obs:object:GetObject (versioning disabled) and obs:object:GetObjectVersion (versioning enabled or suspended) permissions. For details, see Creating a Custom IAM Policy.
- If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you must have the obs:object:getObject (versioning disabled) and obs:object:getObjectVersion (versioning enabled or suspended) permissions, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

Calling Method
For details, see Calling APIs. Before calling this API, calculate the API signature and add it to the request.
You can debug this API in API Explorer.
Request Syntax
1 2 3 4 5 6 | GET /ObjectName HTTP/1.1 Host: bucketname.obs.region.myhuaweicloud.com Date: date Authorization: authorization Range:bytes=byte_range <Optional Additional Header> |
The Range field is optional. If it is not specified, the entire object is downloaded.
URI Parameters
In a GET request, you can override values for a set of message headers using the request parameters. Message headers that you can override are Content-Type, Content-Language, Expires, Cache-Control, Content-Disposition, and Content-Encoding. If the target object has multiple versions, use the versionId parameter to specify the version to be downloaded. For details, see Table 1.
OBS does not process Accept-Encoding carried in a request or compress or decompress the uploaded data. The client determines whether to compress or decompress the data. Some HTTP clients may decompress data based on the Content-Encoding returned by the server. The client program needs to determine whether to decompress and how to decompress the data. To decompress the data, it can modify Content-Encoding (the object metadata stored in OBS) or rewrite Content-Encoding the object is downloaded. If an object download request specifies the rewrite header, the standard HTTP message header returned by OBS is subject to the rewrite content specified in the request.

Using SDKs to Call APIs
You are advised to use OBS SDKs to call APIs. SDKs encapsulate APIs to simplify development. You can call SDK API functions to access OBS without manually calculating signatures.
