(Mono C#) Yahoo Mail Refresh OAuth2 Access TokenSee more Yahoo Mail ExamplesDemonstrates how to refresh an OAuth2 Yahoo Mail access token. For more information, see https://developer.yahoo.com/oauth2/guide/
// 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 Yahoo Mail OAuth2 Access Token Chilkat.JsonObject jsonToken = new Chilkat.JsonObject(); bool success = jsonToken.LoadFile("qa_data/tokens/yahooMail.json"); if (success != true) { Debug.WriteLine("Failed to load googleSheets.json"); return; } // The access token JSON looks like this: // { // "access_token": "kCVQdnOdul...LHucA--", // "refresh_token": "AIenVWETSo0jklFBVkPS8vVm8E.Dj9ToRG.xDbDYmZ55WIs5t6CZhDkD", // "expires_in": 3600, // "token_type": "bearer", // "xoauth_yahoo_guid": "HGDQCVF6JB4YDOWHITPJFBHCWA" // } Chilkat.OAuth2 oauth2 = new Chilkat.OAuth2(); // See Step 5 at https://developer.yahoo.com/oauth2/guide/flows_authcode/ oauth2.TokenEndpoint = "https://api.login.yahoo.com/oauth2/get_token"; // Replace these with actual values. oauth2.ClientId = "CLIENT_ID"; oauth2.ClientSecret = "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 != true) { Debug.WriteLine(oauth2.LastErrorText); return; } // 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. Chilkat.StringBuilder sbJson = new Chilkat.StringBuilder(); jsonToken.EmitCompact = false; jsonToken.EmitSb(sbJson); sbJson.WriteFile("qa_data/tokens/yahooMail.json","utf-8",false); Debug.WriteLine("OAuth2 authorization granted!"); Debug.WriteLine("New Access Token = " + oauth2.AccessToken); |
