Create a New Table in an Azure Storage Account

See more Azure Table Service Examples

Creates a new table using the Azure Table Service REST API. Objective-C

#import <CkoRest.h>
#import <CkoAuthAzureStorage.h>
#import <CkoJsonObject.h>
#import <CkoStringBuilder.h>
#import <NSString.h>

BOOL success = NO;

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

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

// Implements the following CURL command:

// curl -X POST \
//   -H "Content-Type: application/json" \
//   -H "Accept: application/json;odata=fullmetadata" \
//   -H "Prefer: return-content" \
//   -d '{   
//     "TableName":"mytable"  
// }' https://myaccount.table.core.windows.net/Tables

// Use the following online tool to generate REST code from a CURL command
// Convert a cURL Command to REST Source Code

// IMPORTANT: Make sure to change "myaccount" to your actual Azure Storage Account name.
// URL: https://myaccount.table.core.windows.net/Tables

// Provide Azure Cloud credentials for the REST call.
CkoAuthAzureStorage *azAuth = [[CkoAuthAzureStorage alloc] init];

// The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.Account = @"myaccount";
azAuth.Scheme = @"SharedKey";
azAuth.Service = @"Table";

// This causes the "x-ms-version: 2019-07-07" header to be automatically added.
azAuth.XMsVersion = @"2019-07-07";
success = [rest SetAuthAzureStorage: azAuth];

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

// Note: The above code does not need to be repeatedly called for each REST request.
// The rest object can be setup once, and then many requests can be sent.  Chilkat will automatically
// reconnect within a FullRequest* method as needed.  It is only the very first connection that is explicitly
// made via the Connect method.

// Use this online tool to generate code from sample JSON:
// Generate Code to Create JSON

// The following JSON is sent in the request body.

// {
//   "TableName": "mytable"
// }
