Object Storage Service:Restore objects

Usage notes

• Before you run the sample code in this topic, you must create an OSSClient instance by using methods such as using a custom domain name or Security Token Service (STS). For more information, see Initialization.

Sample code

The following code provides an example on how to restore an object named exampleobject.txt in a bucket named examplebucket. The storage class of the exampleobject.txt object is Archive, Cold Archive, or Deep Cold Archive.

OSSRestoreObjectRequest *request = [OSSRestoreObjectRequest new];
// Specify the name of the bucket. Example: examplebucket. 
request.bucketName = @"examplebucket";
// Specify the full path of the object. Do not include the bucket name in the full path. Example: exampleobject.txt. 
request.objectKey = @"exampleobject.txt";

OSSTask *restoreObjectTask = [client restoreObject:request];
[restoreObjectTask continueWithBlock:^id _Nullable(OSSTask * _Nonnull task) {
    if (!task.error) {
        NSLog(@"restore object success");
    } else {
        NSLog(@"restore object failed, error: %@", task.error);
    }
    return nil;
}];
// Implement synchronous blocking to wait for the task to complete. 
// [restoreObjectTask waitUntilFinished];
