AuthAzureSAS Delphi DLL Reference Documentation

AuthAzureSAS

Provides general functionality for Azure Shared Access Signature (SAS) Authorization.

This class is introduced in Chilkat v9.5.0.65.

Create/Dispose

function CkAuthAzureSAS_Create: HCkAuthAzureSAS; stdcall;

Creates an instance of the HCkAuthAzureSAS object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkAuthAzureSAS_Dispose(handle: HCkAuthAzureSAS); stdcall;

Objects created by calling CkAuthAzureSAS_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

procedure CkAuthAzureSAS_getAccessKey(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;
procedure CkAuthAzureSAS_putAccessKey(objHandle: HCkAuthAzureSAS; newPropVal: PWideChar); stdcall;

function CkAuthAzureSAS__accessKey(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Introduced in version 9.5.0.65

This is the signing key (access key) that must be kept private. It is a base64 string such as "abdTvCZFFoWUyre6erlNN+IOb9qhXgDsyhrxmZvpmxqFDwpl9oD0X9Fy0hIQa6L5UohznRLmkCtUYySO4Y2eaw=="

procedure CkAuthAzureSAS_getDebugLogFilePath(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;
procedure CkAuthAzureSAS_putDebugLogFilePath(objHandle: HCkAuthAzureSAS; newPropVal: PWideChar); stdcall;

function CkAuthAzureSAS__debugLogFilePath(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

procedure CkAuthAzureSAS_getLastErrorHtml(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;

function CkAuthAzureSAS__lastErrorHtml(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

procedure CkAuthAzureSAS_getLastErrorText(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;

function CkAuthAzureSAS__lastErrorText(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

Concept of LastErrorText

LastErrorText Standard Information

procedure CkAuthAzureSAS_getLastErrorXml(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;

function CkAuthAzureSAS__lastErrorXml(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

function CkAuthAzureSAS_getLastMethodSuccess(objHandle: HCkAuthAzureSAS): wordbool; stdcall;
procedure CkAuthAzureSAS_putLastMethodSuccess(objHandle: HCkAuthAzureSAS; newPropVal: wordbool); stdcall;

Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = True and failure = False.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

procedure CkAuthAzureSAS_getStringToSign(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;
procedure CkAuthAzureSAS_putStringToSign(objHandle: HCkAuthAzureSAS; newPropVal: PWideChar); stdcall;

function CkAuthAzureSAS__stringToSign(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Introduced in version 9.5.0.65

Defines the format of the string to sign.

The format is specified as a comma-separated list of names. For example:

signedpermissions,signedstart,signedexpiry,canonicalizedresource,signedidentifier,signedIP,signedProtocol,signedversion,rscc,rscd,rsce,rscl,rsct
This will result in an actual string-to-sign that is composed of the values for each name separated by newline (LF) chars. For example:
signedpermissions + "\n" +  
signedstart + "\n" +  
signedexpiry + "\n" +  
canonicalizedresource + "\n" +  
signedidentifier + "\n" +  
signedIP + "\n" +  
signedProtocol + "\n" +  
signedversion + "\n" +  
rscc + "\n" +  
rscd + "\n" +  
rsce + "\n" +  
rscl + "\n" +  
rsct

function CkAuthAzureSAS_getVerboseLogging(objHandle: HCkAuthAzureSAS): wordbool; stdcall;
procedure CkAuthAzureSAS_putVerboseLogging(objHandle: HCkAuthAzureSAS; newPropVal: wordbool); stdcall;

If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

procedure CkAuthAzureSAS_getVersion(objHandle: HCkAuthAzureSAS; outPropVal: HCkString); stdcall;

function CkAuthAzureSAS__version(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Version of the component/library, such as "9.5.0.63"

function CkAuthAzureSAS__generateToken(objHandle: HCkAuthAzureSAS): PWideChar; stdcall;

Introduced in version 9.5.0.65

function CkAuthAzureSAS_SaveLastError(objHandle: HCkAuthAzureSAS;
    path: PWideChar): wordbool; stdcall;

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns True for success, False for failure.

function CkAuthAzureSAS_SetNonTokenParam(objHandle: HCkAuthAzureSAS;
    name: PWideChar;
    value: PWideChar): wordbool; stdcall;

Returns True for success, False for failure.

    name: PWideChar;
    authParamName: PWideChar;
    value: PWideChar): wordbool; stdcall;

Adds a token parameter name/value. This is a value that is included in the string to sign, and is also included as a parameter in the Authorization header.

Returns True for success, False for failure.
