(PHP ActiveX) Google People API Refresh Access TokenDemonstrates how to refresh a Google Access Token for the Google People API.
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // It is assumed we previously obtained an OAuth2 access token. // This example loads the JSON access token file // saved by this example: Get Google People API OAuth2 Access Token // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject') $jsonToken = new COM("Chilkat.JsonObject"); $success = $jsonToken->LoadFile('qa_data/tokens/googlePeople.json'); if ($success != 1) { print 'Failed to load googlePeople.json' . "\n"; exit; } // The access token JSON looks like this: // { // "access_token": "ya29.a0AfH6S ... LAZYFUkf0", // "expires_in": 3599, // "refresh_token": "1//0fL_Ov ... ee0", // "scope": "https://www.googleapis.com/auth/contacts", // "token_type": "Bearer" // } // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.OAuth2') $oauth2 = new COM("Chilkat.OAuth2"); $oauth2->TokenEndpoint = 'https://www.googleapis.com/oauth2/v4/token'; // Replace these with actual values. $oauth2->ClientId = 'GOOGLE-CLIENT-ID'; $oauth2->ClientSecret = 'GOOGLE-CLIENT-SECRET'; // Get the "refresh_token" $oauth2->RefreshToken = $jsonToken->stringOf('refresh_token'); // Send the HTTP POST to refresh the access token.. $success = $oauth2->RefreshAccessToken(); if ($success != 1) { print $oauth2->LastErrorText . "\n"; exit; } // The response contains a new access token, but we must keep // our existing refresh token for when we need to refresh again in the future. $jsonToken->UpdateString('access_token',$oauth2->AccessToken); // Save the new JSON access token response to a file. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder') $sbJson = new COM("Chilkat.StringBuilder"); $jsonToken->EmitCompact = 0; $jsonToken->EmitSb($sbJson); $sbJson->WriteFile('qa_data/tokens/googlePeople.json','utf-8',0); print 'OAuth2 authorization granted!' .
