AuthAzureStorage Class Overview.
Authenticate Azure Storage REST requests with account-key Shared Key signing.
Chilkat.AuthAzureStorage is a credential object for Azure
Storage Services authentication. It stores the storage account name, Base64
account access key, Azure Storage service type, authentication scheme, and
x-ms-version API version used when signing REST requests for
Blob, Queue, File, or Table storage.
Azure Storage credentials
Shared Key signing
SharedKey or
SharedKeyLite, depending on the service and request style.
Service targeting
Blob, Queue, File, or
Table.
API version header
x-ms-version value required by the Azure Storage
REST API version being used.
REST integration
Chilkat.Rest so requests are
signed automatically before being sent.
Low-level control
AuthAzureStorage object, set the storage
Account, Base64 AccessKey, Service,
Scheme, and XMsVersion, then attach it to a
Chilkat.Rest request workflow. Use
AuthAzureStorage for Shared Key authorization headers; use
Chilkat.AuthAzureSAS when the request should be authorized with
a SAS query token instead.
Object Creation
use Chilkat2;
my $authAzureStorage = Chilkat2::AuthAzureStorage->new;
# or set properties (and RaiseError) at creation:
# my $authAzureStorage = Chilkat2::AuthAzureStorage->new(VerboseLogging => 1, RaiseError => 1);Creates the object. The optional pairs set writable properties (and RaiseError) in order, as if set one by one; an unknown or read-only name croaks. use Chilkat2; loads every class; the Chilkat2/AuthAzureStorage.pm file holds only this class's documentation (perldoc Chilkat2::AuthAzureStorage).
Perl frees the object when its last reference goes (undef $authAzureStorage, or the variable going out of scope); there is nothing to close. Objects returned by methods are independent and freed the same way. The class may be subclassed (use parent -norequire, 'Chilkat2::AuthAzureStorage';): an object is a blessed hash reference whose hash is free for the subclass's own fields.
When false (the default), a method that fails returns false (or undef), and the reason is in LastErrorText. When true, it dies with a Chilkat2::Error instead, as DBI does with its RaiseError. Objects returned by a method inherit the value of the object that returned them.
Errors
A Chilkat2::Error stringifies to the failed call's full LastErrorText, and has the methods text, class ('Chilkat2::AuthAzureStorage'), method (the method name) and object. Methods that look something up and find nothing return undef without dying (each such method says so), methods that answer a question (HasMember, IsUnlocked, ...) return a plain boolean, and property reads and writes never fail for Chilkat reasons.
Misuse always croaks, with your file and line, whatever RaiseError is: a wrong number of arguments, a reference or undef where a string or number is expected, an object of the wrong class, an out-of-range integer, a string containing a NUL character, a wide character in a byte string, or a write to a read-only property.
Strings are Perl character strings in both directions (length, regexes and :encoding layers see characters); binary data (BinData) is a byte string. Unlocking: call Chilkat2::Global->new->UnlockBundle('...') once at startup.
Properties
AccessKey
my $strVal = $authAzureStorage->AccessKey;
$authAzureStorage->AccessKey($strVal);
Account
my $strVal = $authAzureStorage->Account;
$authAzureStorage->Account($strVal);
The Azure storage account name. (A storage account can contain zero or more containers. A container contains properties, metadata, and zero or more blobs. A blob is any single entity comprised of binary data, properties, and metadata. )
topDebugLogFilePath
my $strVal = $authAzureStorage->DebugLogFilePath;
$authAzureStorage->DebugLogFilePath($strVal);
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastErrorHtml
my $strVal = $authAzureStorage->LastErrorHtml;
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
my $strVal = $authAzureStorage->LastErrorText;
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
my $strVal = $authAzureStorage->LastErrorXml;
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
my $boolVal = $authAzureStorage->LastMethodSuccess;
$authAzureStorage->LastMethodSuccess($boolVal);
Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.
Scheme
my $strVal = $authAzureStorage->Scheme;
$authAzureStorage->Scheme($strVal);
Can be SharedKey or SharedKeyLite. The default value is SharedKey.
Service
my $strVal = $authAzureStorage->Service;
$authAzureStorage->Service($strVal);
Can be Blob, Queue, File, or Table. The default is Blob.
Note: Authentication for the Table service did not work in versions prior to v9.5.0.83.
VerboseLogging
my $boolVal = $authAzureStorage->VerboseLogging;
$authAzureStorage->VerboseLogging($boolVal);
If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version
my $strVal = $authAzureStorage->Version;
XMsVersion
my $strVal = $authAzureStorage->XMsVersion;
$authAzureStorage->XMsVersion($strVal);
If set, automatically adds the x-ms-version HTTP request header to Azure Storage requests. The default value is 2014-02-14.
