Properties
AccessToken
Procedure Set ComAccessToken String value
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.
topDebugLogFilePath
Procedure Set ComDebugLogFilePath String value
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.
EmailAddress
Procedure Set ComEmailAddress String value
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.
ExpireNumSeconds
Procedure Set ComExpireNumSeconds Integer value
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.
topIat
Procedure Set ComIat Integer value
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.
topJsonKey
Procedure Set ComJsonKey String value
The JSON key for obtaining an access token. An application must set either the P12 or JSON private key, but not both.
LastBinaryResult
This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to True. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.
topLastErrorHtml
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
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
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
Procedure Set ComLastMethodSuccess Boolean value
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.
topLastStringResult
In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topNumSecondsRemaining
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.
topScope
Procedure Set ComScope String value
A space-delimited list of the permissions that the application requests.
topSubEmailAddress
Procedure Set ComSubEmailAddress String value
The email address of the user for which the application is requesting delegated access.
topValid
True if the AccessToken property contains a valid non-expired access token obtained via the call to ObtainAccessToken.
topVerboseLogging
Procedure Set ComVerboseLogging Boolean value
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.
topVersion
Methods
AddClaims
Adds additional custom claims to the JWT claims set.
Returns True for success, False for failure.
GetP12
Returns the private key in a PFX (P12) object. This is only possible if the private key was previously set by calling SetP12.
Returns null on failure
topLoadTaskCaller
ObtainAccessToken
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.
ObtainAccessTokenAsync (1)
Creates an asynchronous task to call the ObtainAccessToken method with the arguments provided.
Returns null on failure
topSetP12
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.
