Sample code to list the file shares in an Azure storage account.

Note: This example requires Chilkat v11.0.0 or greater.

* Azure File Service Example: List all the file shares in a storage account.
* See also: https://docs.microsoft.com/en-us/rest/api/storageservices/list-shares

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

loRest = CreateObject('Chilkat.Rest')

* Connect to the Azure Storage Blob Service
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
* In this example, the storage account name is "chilkat".
lnSuccess = loRest.Connect("chilkat.file.core.windows.net",lnPort,lnBTls,lnBAutoReconnect)
IF (lnSuccess = 0) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

* Provide Azure Cloud credentials for the REST call.
loAzAuth = CreateObject('Chilkat.AuthAzureStorage')
loAzAuth.AccessKey = "AZURE_ACCESS_KEY"
* The account name used here should match the 1st part of the domain passed in the call to Connect (above).
loAzAuth.Account = "chilkat"
loAzAuth.Scheme = "SharedKey"
loAzAuth.Service = "File"
* This causes the "x-ms-version: 2021-08-06" header to be automatically added.
loAzAuth.XMsVersion = "2021-08-06"
lnSuccess = loRest.SetAuthAzureStorage(loAzAuth)

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

* Send the GET request to list the shares.
lcResponseStr = loRest.FullRequestNoBody("GET","/?comp=list")
IF (loRest.LastMethodSuccess = 0) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

* When successful, the Azure Storage service will respond with a 200 response status code,
* with an XML response body.

IF (loRest.ResponseStatusCode <> 200) THEN
    * Examine the request/response to see what happened.
    ? "response status code = " + STR(loRest.ResponseStatusCode)
    ? "response status text = " + loRest.ResponseStatusText
    ? "response header: " + loRest.ResponseHeader
    ? "response body (if any): " + lcResponseStr
    ? "---"
    ? "LastRequestStartLine: " + loRest.LastRequestStartLine
    ? "LastRequestHeader: " + loRest.LastRequestHeader
    RELEASE loRest
    RELEASE loAzAuth
    CANCEL
ENDIF

* Load the XML response for parsing.
* An example of the response XML is shown below.
loXml = CreateObject('Chilkat.Xml')
lnSuccess = loXml.LoadXml(lcResponseStr)

? loXml.GetXml()

* Here's a sample response:

* <?xml version="1.0" encoding="utf-8" ?>
* <EnumerationResults ServiceEndpoint="https://chilkat.file.core.windows.net/">
*     <Shares>
*         <Share>
*             <Name>beardie</Name>
*             <Properties>
*                 <Last-Modified>Mon, 26 Jun 2017 21:24:57 GMT</Last-Modified>
*                 <Etag>"0x8D4BCD9CBD872E5"</Etag>
*                 <Quota>5120</Quota>
*             </Properties>
*         </Share>
*         <Share>
*             <Name>pip</Name>
*             <Properties>
*                 <Last-Modified>Mon, 26 Jun 2017 21:24:44 GMT</Last-Modified>
*                 <Etag>"0x8D4BCD9C3D823D1"</Etag>
*                 <Quota>5120</Quota>
*             </Properties>
*         </Share>
*     </Shares>
*     <NextMarker />
* </EnumerationResults>

* Let's iterate over the file shares
loLastMod = CreateObject('Chilkat.CkDateTime')

lnNumShares = loXml.NumChildrenAt("Shares")
i = 0
loDt = CreateObject('Chilkat.DtObj')
DO WHILE i < lnNumShares
    ? "---- Share " + STR(i) + " ----"
    loXml.I = i
    ? "Name: " + loXml.GetChildContent("Shares|Share[i]|Name")
    loLastMod.SetFromRfc822(loXml.GetChildContent("Shares|Share[i]|Properties|Last-Modified"))
    loLastMod.ToDtObj(1,loDt)

    ? "Last-Modified YMD: " + STR(loDt.Year) + "," + STR(loDt.Month) + "," + STR(loDt.Day)
    i = i + 1
ENDDO

* Output for the above loop:

* ---- Share 0 ----
* Name: beardie
* Last-Modified YMD: 2017,6,26
* ---- Share 1 ----
* Name: pip
* Last-Modified YMD: 2017,6,26
* 

? "Success."
