(PHP ActiveX) Refresh Cloud Storage OAuth2 Access Token (Authorization Code Flow)See more Google Cloud Storage ExamplesDemonstrates how to refresh an expired or soon-to-expire Cloud Storage OAuth2 access token obtained by the Authorization Code Flow (i.e. NOT for a Service Account).
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject') $jsonToken = new COM("Chilkat.JsonObject"); $success = $jsonToken->LoadFile('qa_data/tokens/googleCloudStorage.json'); if ($success != 1) { print 'Failed to load googleCloudStorage.json' . "\n"; exit; } // The access token JSON looks like this: // { // "access_token": "ya29.a0Ad52N3_4eOd5_T7....", // "token_type": "Bearer", // "expires_in": 3600, // "refresh_token": "1/lEe5abcdNJ77eOSDBabcdkQGVmDalkwabcdR2Hatbo" // } // // 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/googleCloudStorage.json','utf-8',0); print 'OAuth2 authorization granted!' .
