AuthGoogle Tcl Reference Documentation

AuthGoogle

Current Version: 10.1.2

Provides functionality for authenticating calls to the Google Cloud Platform API and Google Apps API using a service account.

Object Creation

set myAuthGoogle [new CkAuthGoogle]

Properties

AccessToken
string
# ckStr is a CkString
CkAuthGoogle_get_AccessToken $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_accessToken $myAuthGoogle]
CkAuthGoogle_put_AccessToken $myAuthGoogle $strVal
Introduced in version 9.5.0.58

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.

DebugLogFilePath
string
# ckStr is a CkString
CkAuthGoogle_get_DebugLogFilePath $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_debugLogFilePath $myAuthGoogle]
CkAuthGoogle_put_DebugLogFilePath $myAuthGoogle $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.

EmailAddress
string
# ckStr is a CkString
CkAuthGoogle_get_EmailAddress $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_emailAddress $myAuthGoogle]
CkAuthGoogle_put_EmailAddress $myAuthGoogle $strVal
Introduced in version 9.5.0.58

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.

top
ExpireNumSeconds
integer
set intVal [CkAuthGoogle_get_ExpireNumSeconds $myAuthGoogle]
CkAuthGoogle_put_ExpireNumSeconds $myAuthGoogle $intVal
Introduced in version 9.5.0.58

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
Iat
integer
set intVal [CkAuthGoogle_get_Iat $myAuthGoogle]
CkAuthGoogle_put_Iat $myAuthGoogle $intVal
Introduced in version 9.5.0.77

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
JsonKey
string
# ckStr is a CkString
CkAuthGoogle_get_JsonKey $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_jsonKey $myAuthGoogle]
CkAuthGoogle_put_JsonKey $myAuthGoogle $strVal
Introduced in version 9.5.0.58

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

top
LastErrorHtml
string
# ckStr is a CkString
CkAuthGoogle_get_LastErrorHtml $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_lastErrorHtml $myAuthGoogle]

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.

top
LastErrorText
string
# ckStr is a CkString
CkAuthGoogle_get_LastErrorText $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_lastErrorText $myAuthGoogle]

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.

top
LastErrorXml
string
# ckStr is a CkString
CkAuthGoogle_get_LastErrorXml $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_lastErrorXml $myAuthGoogle]

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.

top
LastMethodSuccess
boolean 1/0
set boolVal [CkAuthGoogle_get_LastMethodSuccess $myAuthGoogle]
CkAuthGoogle_put_LastMethodSuccess $myAuthGoogle $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.

top
NumSecondsRemaining
integer
set intVal [CkAuthGoogle_get_NumSecondsRemaining $myAuthGoogle]
Introduced in version 9.5.0.58

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
Scope
string
# ckStr is a CkString
CkAuthGoogle_get_Scope $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_scope $myAuthGoogle]
CkAuthGoogle_put_Scope $myAuthGoogle $strVal
Introduced in version 9.5.0.58

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

top

CkAuthGoogle_put_SubEmailAddress $myAuthGoogle $strVal
Introduced in version 9.5.0.58

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

top
Utf8
boolean 1/0
set boolVal [CkAuthGoogle_get_Utf8 $myAuthGoogle]
CkAuthGoogle_put_Utf8 $myAuthGoogle $boolVal

When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.

top
Valid
boolean 1/0
set boolVal [CkAuthGoogle_get_Valid $myAuthGoogle]
Introduced in version 9.5.0.58

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

top
VerboseLogging
boolean 1/0
set boolVal [CkAuthGoogle_get_VerboseLogging $myAuthGoogle]
CkAuthGoogle_put_VerboseLogging $myAuthGoogle $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.

top
Version
string
# ckStr is a CkString
CkAuthGoogle_get_Version $myAuthGoogle $ckStr
set strVal [CkAuthGoogle_get_version $myAuthGoogle]

Check your iat and exp values and use a clock with skew to account for clock differences between systems.".
