Restoring an Archived Object

Feature description

This API is used to retrieve an archived object for access.

Sample code

Objective-C

objective-c
QCloudPostObjectRestoreRequest *req = [QCloudPostObjectRestoreRequest new];
// Bucket name in the format: `BucketName-APPID`
req.bucket = @"examplebucket-1250000000";
// Object key, i.e. the full path of a COS object. If the object is in a directory, the path should be "video/xxx/movie.mp4"
req.object = @"exampleobject";
// Set the expiration time of the temporary copy
req.restoreRequest.days  = 10;
// Configuration of the restoration type
req.restoreRequest.CASJobParameters.tier =QCloudCASTierStandard;
[req setFinishBlock:^(id outputObject, NSError *error) {

   // `outputObject` contains all the HTTP response headers
   NSDictionary* info = (NSDictionary *) outputObject;

}];
[[QCloudCOSXMLService defaultCOSXML] PostObjectRestore:req];

Swift

swift
let restore = QCloudPostObjectRestoreRequest.init();
// Bucket name in the format: `BucketName-APPID`
restore.bucket = "examplebucket-1250000000";
// Object key, i.e. the full path of a COS object. If the object is in a directory, the path should be "video/xxx/movie.mp4"
restore.object = "exampleobject";
// Set the expiration time of the temporary copy
restore.restoreRequest.days = 10;
// Configuration of the restoration type
restore.restoreRequest.casJobParameters.tier = .standard;
restore.finishBlock = {(result,error)in
   if let result = result {
       // "result" contains response headers
   } else {
       print(error!);
   }
}
QCloudCOSXMLService.defaultCOSXML().postObjectRestore(restore);
