Azure Storage Blob Service REST API: Sample code to set a blob's service properties. B4X

Dim success As Boolean = False

'  Azure Blob Service Example: Set Blob Service Properties
'  See also: https://msdn.microsoft.com/en-us/library/azure/hh452235.aspx

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

Dim rest As ChilkatRest
rest.Initialize("rest")

'  Connect to the Azure Storage Blob Service
Dim bTls As Boolean = True
Dim port As Int = 443
Dim bAutoReconnect As Boolean = True
'  In this example, the storage account name is "chilkat".
success = rest.Connect("chilkat.blob.core.windows.net", port, bTls, bAutoReconnect)
If success <> True Then
    Log(rest.LastErrorText)
    Return
End If


'  Provide Azure Cloud credentials for the REST call.
Dim azAuth As ChilkatAuthAzureStorage
azAuth.Initialize
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.

'  This example will set logging properties.  The XML body of the request
'  will look like this:

'  <?xml version="1.0" encoding="utf-8"?>
'  <StorageServiceProperties>
'      <Logging>
'          <Version>version-number</Version>
'          <Delete>true|false</Delete>
'          <Read>true|false</Read>
'          <Write>true|false</Write>
'          <RetentionPolicy>
'              <Enabled>true|false</Enabled>
'              <Days>number-of-days</Days>
'          </RetentionPolicy>
'      </Logging>

'  Build the request:
Dim xml As ChilkatXml
xml.Initialize
xml.Tag = "StorageServiceProperties"
Dim xLogging As ChilkatXml = xml.NewChild("Logging", "")
xLogging.NewChild2("Version", "1.0")
xLogging.NewChild2("Delete", "true")
xLogging.NewChild2("Read", "true")
xLogging.NewChild2("Write", "true")
Dim xRetension As ChilkatXml = xLogging.NewChild("RetentionPolicy", "")

xRetension.NewChild2("Days", "7")



'  The expected response is a 202 response status code with no response body.
Dim responseStr As String = rest.FullRequestString("PUT", "/?restype=service&comp=properties", xml.GetXml)
If rest.LastMethodSuccess <> True Then

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