    Restoring an Archived Object


    This API (POST Object restore) is used to restore an archived object for access.

    Sample code

    // Bucket name in the format of BucketName-APPID (APPID is required), which can be viewed in the COS console at https://console.tencentcloud.com/cos5/bucket
    String bucket = "examplebucket-1250000000";
    String cosPath = "exampleobject"; // The location identifier of the object in the bucket, i.e., the object key
    RestoreRequest restoreRequest = new RestoreRequest(bucket, cosPath);
    restoreRequest.setExpireDays(5); // Retain for 5 days
    restoreRequest.setTier(RestoreConfigure.Tier.Standard); // Standard restoration mode
    cosXmlService.restoreObjectAsync(restoreRequest, new CosXmlResultListener() {
       public void onSuccess(CosXmlRequest request, CosXmlResult result) {
           RestoreResult restoreResult = (RestoreResult) result;
        // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
       // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
       public void onFail(CosXmlRequest cosXmlRequest,
                          @Nullable CosXmlClientException clientException,
                          @Nullable CosXmlServiceException serviceException) {
           if (clientException != null) {
           } else {
