(Mono C#) Google Drive Refresh Access TokenDemonstrates how to automatically refresh the access token when it expires.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. bool success = true; // This example uses a previously obtained access token having permission for the // Google Drive scope. // The access token (and refresh token) was previously saved to a JSON file with this format: // See Get Google Drive OAuth2 Access Token // { // "access_token": "ya29.Gls-BsdxTWuenChv ... yzVIrXikkLxu5T6dy4I6GjADFardoz4Lruw", // "expires_in": 3600, // "refresh_token": "1/tMBJ ... 27D-Hk6rpQYBA", // "scope": "https://www.googleapis.com/auth/drive", // "token_type": "Bearer" // } Chilkat.JsonObject json = new Chilkat.JsonObject(); string tokenFilePath = "qa_data/tokens/googleDrive.json"; json.LoadFile(tokenFilePath); Chilkat.OAuth2 oauth2 = new Chilkat.OAuth2(); oauth2.AccessToken = json.StringOf("access_token"); oauth2.RefreshToken = json.StringOf("refresh_token"); oauth2.AuthorizationEndpoint = "https://accounts.google.com/o/oauth2/v2/auth"; oauth2.TokenEndpoint = "https://www.googleapis.com/oauth2/v4/token"; // Replace these with actual values. oauth2.ClientId = "GOOGLE-CLIENT-ID"; oauth2.ClientSecret = "GOOGLE-CLIENT-SECRET"; oauth2.Scope = "https://www.googleapis.com/auth/drive"; // Use OAuth2 to refresh the access token. success = oauth2.RefreshAccessToken(); if (success != true) { Debug.WriteLine(oauth2.LastErrorText); return; } Debug.WriteLine(oauth2.AccessTokenResponse); // Save the new access token to our JSON file (so we can refresh it again when needed). json.UpdateString("access_token",oauth2.AccessToken); Chilkat.FileAccess fac = new Chilkat.FileAccess(); fac.WriteEntireTextFile(tokenFilePath,json.Emit(),"utf-8",false); Debug.WriteLine("Access Token Refreshed!"); |
