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.
<b>Important:</b> This class is used for authenticating calls to the Google Cloud Platform API and Google Apps API using a <b>service account.</b>. 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.top
Procedure Set ComDebugLogFilePath String value
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:
- a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
- the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
- there is an internal problem (bug) in the Chilkat code that causes the hang.
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.
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.top
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.top
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.
The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to True. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).top
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.top
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.top
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.top
Procedure Set ComLastMethodSuccess Boolean value
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.top
The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to True. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).
The length, in characters, of the string contained in the LastStringResult property.top
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.top
Procedure Set ComScope String value
A space-delimited list of the permissions that the application requests.top
Procedure Set ComSubEmailAddress String value
The email address of the user for which the application is requesting delegated access.top
True if the AccessToken property contains a valid non-expired access token obtained via the call to ObtainAccessToken.top
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.top
Version of the component/library, such as "220.127.116.11"top
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 failuretop
Loads the caller of the task's async method.
Returns True for success, False for failure.top
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. (Async methods are available starting in Chilkat v18.104.22.168.)
Returns null on failuretop
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.
