我用dotnetOpenAuth。我想向用戶的gamil請求授權。想用dotnetOpenAuth請求gmail授權

我需要先使用openId嗎?

找不到像樣的tutorail。誰能幫忙?

嘗試此代碼unsuccesfully。反正我不似乎要求在身份驗證請求Gmail的範圍,所以我很困惑

public void PrepareAuthorizationRequest(Uri authCallbakUrl) 
{ 
    var consumer = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 

    // request access 
    consumer.Channel.Send(consumer.PrepareRequestUserAuthorization(authCallbakUrl, null, null)); 

    throw new NoRedirectToAuthPageException(); 
} 

public ProcessAuthorizationRequestResponse ProcessAuthorizationRequest() 
{ 
    ProcessAuthorizationRequestResponse response; 
    // Process result from the service provider 
    var consumer = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 
    var accessTokenResponse = consumer.ProcessUserAuthorization(); 

    // If we didn't have an access token response, this wasn't called by the service provider 
    if (accessTokenResponse == null) 
     response = new ProcessAuthorizationRequestResponse 
         { 
          IsAuthorized = false 
         }; 
    else 
    { 
     // Extract the access token 
     string accessToken = accessTokenResponse.AccessToken; 
     response = new ProcessAuthorizationRequestResponse 
     { 
      IsAuthorized = true, 
      Token = accessToken, 
      Secret = mConsumerTokenManager.GetTokenSecret(accessToken) 
     }; 
    } 
    return response; 
} 

private string Test2() 
{ 
    // Process result from linked in 
    var google = new WebConsumer(GoogleConsumerConsts.ServiceDescription, mConsumerTokenManager); 
    // var accessToken = GetAccessTokenForUser(); 
    var accessToken = String.Empty; 

    // Retrieve the user's profile information 
    var endpoint = GoogleConsumerConsts.GetGmailFeedsEndpoint;// new MessageReceivingEndpoint("http://api.linkedin.com/v1/people/~", HttpDeliveryMethods.GetRequest); 
    var request = google.PrepareAuthorizedRequest(endpoint, accessToken); 
    var response = request.GetResponse(); 
    return (new StreamReader(response.GetResponseStream())).ReadToEnd(); 
}

不,你並不需要使用OpenID的,如果你只是想訪問用戶的Gmail。 OpenID適用於您想要驗證用戶的情況。 OAuth用於訪問用戶數據。

您需要在您的授權請求中包含scope參數,如此問題所述:Adding scopes to OAuth 1.0 authorization request with DotNetOpenAuth

如果我不使用openAuth,我應該在數據庫中保存什麼,以便下次識別用戶? requestToken是永久且唯一的嗎?第二次使用者的流量是多少? – 2012-03-04 22:26:06

請求令牌或訪問令牌不是持久的。如果您希望能夠在下次識別用戶時,可以使用OpenID *(除了OAuth之外還可以實際閱讀他們的Gmail)。在這種情況下,您應該查看'openidrelyingpartywebforms/loginplusoauth.aspx'示例,這些示例使用Google *登錄用戶,以及*訪問其Gmail地址簿。 – 2012-03-05 01:06:57

它會導致用戶雙重重定向?一次用於身份驗證,一次用於授權? – 2012-03-05 19:00:15
