(JavaScript) Azure Storage: Get Blob Service Properties

Azure Storage Blob Service REST API: Sample code to get a blob's service properties.

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: Get Blob Service Properties

// 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.

var responseStr = rest.FullRequestNoBody("GET","/?restype=service&comp=properties");
if (rest.LastMethodSuccess !== true) {
    console.log(rest.LastErrorText);
    return;
}

// When successful, the Azure Storage service will respond with a 200 response code,
// with an XML body.  
if (rest.ResponseStatusCode !== 200) {
    // 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;
}

// Load the XML response for parsing.
// An example of the response XML is shown below.
var xml = new CkXml();
success = xml.LoadXml(responseStr);

console.log(xml.GetXml());

// Use the ChilkatPath method to get various pieces of information out
// of the XML.  For example:

console.log("Logging retention policy #days = " + xml.ChilkatPath("Logging|RetentionPolicy|Days|*"));
console.log("Hour metrics include APIs = " + xml.ChilkatPath("HourMetrics|IncludeAPIs|*"));
