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

CkoRest *rest = [[CkoRest alloc] init];

// Connect to the Azure Storage Blob Service
BOOL bTls = YES;
int port = 443;
BOOL bAutoReconnect = YES;
// In this example, the storage account name is "chilkat".
BOOL success = [rest Connect: @"chilkat.blob.core.windows.net" port: [NSNumber numberWithInt: port] tls: bTls autoReconnect: bAutoReconnect];
if (success != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;
}

// Provide Azure Cloud credentials for the REST call.
CkoAuthAzureStorage *azAuth = [[CkoAuthAzureStorage alloc] init];
azAuth.AccessKey = @"AZURE_ACCESS_KEY";
// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = @"chilkat";
azAuth.Scheme = @"SharedKey";
azAuth.Service = @"Blob";
// This causes the "x-ms-version: 2020-08-04" header to be automatically added.
azAuth.XMsVersion = @"2020-08-04";
success = [rest SetAuthAzureStorage: azAuth];

// Note: The application does not need to explicitly set the following
// headers: x-ms-date, Authorization.  These headers
// are automatically set by Chilkat.

// To call Delete Container on a container that has an active lease, specify the lease ID in this header. 
// If this header is not specified when there is an active lease, Delete Container will return 409 (Conflict). 
// If you specify the wrong lease ID, or a lease ID on a container that does not have an active lease, 
// Delete Container will return 412 (Precondition failed).

// IMPORTANT: Delete this line, or insert a valid lease ID, otherwise the request
// will fail with a 400 status code..
success = [rest AddHeader: @"x-ms-lease-id" value: @"SOME_LEASE_ID"];

// The expected success response is a 202 response status code with no response body.
// In this example, the container to be deleted is named "mycontainer".
NSString *responseStr = [rest FullRequestNoBody: @"DELETE" uriPath: @"/mycontainer?restype=container"];
if (rest.LastMethodSuccess != YES) {
    NSLog(@"%@",rest.LastErrorText);

// When successful, the Azure Storage service will respond with a 202 response code,
// with no response body.

// If the container with the same name already exists, then the operation will fail.

    // Examine the request/response to see what happened.
