AuthGoogle

The access token to be used in Google API requests. This property is set on a successful call to ObtainAccessToken.

Important: This class is used for authenticating calls to the Google Cloud Platform API and Google Apps API using a service account.. For 3-legged OAuth2, where a browser must be used to interactively get permission from the Google account owner, use the Chilkat OAuth2 class/object.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

The client email address of the service account. If a JSON key is used, then the client_email should already be specified within the JSON key, and this property is unused. This property must be set if using a P12 key.

See the notes about PWideChar memory ownership and validity.

The expiration time, in seconds, of the access token to be requested. The maximum value is 1 hour (3600 seconds). The default value is 3600.

This property can be set to override the default current date/time value for the iat claim of the JWT. It can be set to a value indicating the number of seconds from 1970-01-01T00:00:00Z UTC.

The default value is 0, which indicates to use the iat value for the current system date/time. Unless explicitly needed, always leave this property at the default value.

The JSON key for obtaining an access token. An application must set either the P12 or JSON private key, but not both.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

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.

See the notes about PWideChar memory ownership and validity.

Indicates the success or failure of the most recent method call: True means success, False 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.

If the access token is valid, contains the number of seconds remaining until it expires. A value of 0 indicates an invalid or expired access token.

A space-delimited list of the permissions that the application requests.

See the notes about PWideChar memory ownership and validity.

The email address of the user for which the application is requesting delegated access.

See the notes about PWideChar memory ownership and validity.

True if the AccessToken property contains a valid non-expired access token obtained via the call to ObtainAccessToken.

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.

Version of the component/library, such as "10.1.0"

See the notes about PWideChar memory ownership and validity.

Adds additional custom claims to the JWT claims set.

Returns True for success, False for failure.

Returns the private key in a PFX (P12) object. This is only possible if the private key was previously set by calling SetP12.

Returns nil on failure

Loads the caller of the task's async method.

Returns True for success, False for failure.

Sends the HTTP request to fetch the access token. When this method completes successfully, the access token is available in the AccessToken property. The connection is an existing connection to www.googleapis.com.

Important: Make sure your computer's date/time is accurately set to the current date/time, otherwise you'll get a 400 response status code with this error: Invalid JWT: Token must be a short-lived token (60 minutes) and in a reasonable timeframe. Check your iat and exp values and use a clock with skew to account for clock differences between systems..

Returns True for success, False for failure.

Creates an asynchronous task to call the ObtainAccessToken method with the arguments provided.

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Returns nil on failure

Sets the P12 private key to be used for obtaining an access token. An application must set either the P12 or JSON private key, but not both.

Returns True for success, False for failure.

Enables a method call to be aborted by triggering the AbortCheck event at intervals defined by the HeartbeatMs property. If HeartbeatMs is set to its default value of 0, no events will occur. For instance, set HeartbeatMs to 200 to trigger 5 AbortCheck events per second. Return True to abort; return False to continue (not abort)

This provides the percentage completion for any method involving network communications or time-consuming processing, assuming the progress can be measured as a percentage. This event is triggered only when it's possible and logical to express the operation's progress as a percentage. The pctDone argument will range from 1 to 100. For methods that finish quickly, the number of PercentDone callbacks may vary, but the final callback will have pctDone equal to 100. For longer operations, callbacks will not exceed one per percentage point (e.g., 1, 2, 3, ..., 98, 99, 100).

The PercentDone callback also acts as an AbortCheck event. For fast methods where PercentDone fires, an AbortCheck event may not trigger since the PercentDone callback already provides an opportunity to abort. For longer operations, where time between PercentDone callbacks is extended, AbortCheck callbacks enable more responsive operation termination.

Return True to abort; return False to continue (not abort)

This event callback provides tag name/value pairs that detail what occurs during a method call. To discover existing tag names, create code to handle the event, emit the pairs, and review them. Most tag names are self-explanatory.

Called from the background thread when an asynchronous task completes.
