Demonstrates how to download a file from a Backblaze bucket.

The Chilkat S3 functions in the HTTP class are compatible with the Backblaze service. However, because of some specific issues, Chilkat v9.5.0.89 or later is needed.

Objective-C

#import <CkoHttp.h>
#import <NSString.h>

BOOL success = NO;

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoHttp *http = [[CkoHttp alloc] init];

// keyID = Access Key ID or Access Key
http.AwsAccessKey = @"access-key";

// applicationKey = Secret Access Key or Secret Key
http.AwsSecretKey = @"secret-key";

// Region is the 2nd part of your S3 Endpoint
http.AwsEndpoint = @"s3.us-west-002.backblazeb2.com";

NSString *bucketName = @"chilkat-test";
NSString *objectName = @"seahorse.jpg";
NSString *localFilePath = @"qa_output/seahorse.jpg";

success = [http S3_DownloadFile: bucketName objectName: objectName localFilePath: localFilePath];
if (success != YES) {
