(JavaScript) Azure Storage: Delete Blob

Demonstrates the Azure Delete Blob operation, which marks the specified blob for deletion. The blob is later deleted during garbage collection.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// Azure Blob Service Example: Delete a particular blob in a specified container.
// See also: https://docs.microsoft.com/en-us/rest/api/storageservices/delete-blob

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

var rest = new CkRest();

// Connect to the Azure Storage Blob Service
var bTls = true;
var port = 443;
var bAutoReconnect = true;
// In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect);
if (success !== true) {
    console.log(rest.LastErrorText);
    return;
}

// Provide Azure Cloud credentials for the REST call.
var azAuth = new CkAuthAzureStorage();
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: 2021-08-06" header to be automatically added.
azAuth.XMsVersion = "2021-08-06";
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.

// A successful operation returns status code 202 (Accepted) with no response body.
// This example deletes the blob named "helloWorld.txt" located in "mycontainer"
var responseStr = rest.FullRequestNoBody("DELETE","/mycontainer/helloWorld.txt");
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

if (rest.ResponseStatusCode !== 202) {
    // Examine the request/response to see what happened.
    console.log("response status code = " + rest.ResponseStatusCode);
    console.log("response status text = " + rest.ResponseStatusText);
    console.log("response header: " + rest.ResponseHeader);
    console.log("response body (if any): " + responseStr);
    console.log("---");
    console.log("LastRequestStartLine: " + rest.LastRequestStartLine);
    console.log("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

console.log("Successfully deleted the blob!");
