OpenID：試圖從谷歌獲得電子郵件地址OP

Question

我正在使用dotnetopenauth 3.2來實現Openid，但無法弄清楚如何讓Google在索賠響應中傳遞電子郵件地址。我知道Google不支持簡單的註冊，但我無法確定他們的支持。

買者對這個問題是我剛開始學習的OpenID，我知道我沒有關於這一點我認爲是導致我的困惑規範紮實掌握。

任何幫助，將不勝感激！

Answer 1

好吧，算了一下。我發佈了一個關於Goolge's Federated Log API group的問題，並被告知使用Attribute exchange。

以下是DotNetOpenAuth的代碼。

請不要在生產中使用此代碼。這僅用於說明目的！

的請求：

using (OpenIdRelyingParty openid = new OpenIdRelyingParty()) 
{ 
    IAuthenticationRequest request = openid.CreateRequest(openidurl); 

    var fetch = new FetchRequest(); 
    fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email); 
    request.AddExtension(fetch); 

    // Send your visitor to their Provider for authentication. 
    request.RedirectToProvider(); 
} 

的迴應：

OpenIdRelyingParty openid = new OpenIdRelyingParty(); 
var response = openid.GetResponse(); 
if (response != null) 
{ 
    switch (response.Status) 
    { 
     case AuthenticationStatus.Authenticated: 
     { 
      var fetch = response.GetExtension<FetchResponse>(); 
      string email = string.Empty(); 
      if (fetch != null) 
      { 
       email = fetch.GetAttributeValue(
        WellKnownAttributes.Contact.Email); 
      } 

      FormsAuthentication.RedirectFromLoginPage(
       response.ClaimedIdentifier, false); 
      break; 
     } 
     ... 
    } 
} 

Answer 2

當我試圖讓全名的響應爲空，請提供一個解決方案，以獲得全名， 這帖子真的有幫助 謝謝。 我的示例代碼是這樣的。

var fetch = new FetchRequest(); 
      fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email); 
      fetch.Attributes.AddRequired(WellKnownAttributes.Name.FullName); 
      fetch.Attributes.AddRequired(WellKnownAttributes.Company.CompanyName); 
      //fetch.Attributes.AddRequired(WellKnownAttributes.Contact.Email); 

      request.AddExtension(fetch); 

而

if (fetch != null) 
     { 
      email = fetch.GetAttributeValue(WellKnownAttributes.Contact.Email); 
      name = fetch.GetAttributeValue(WellKnownAttributes.Name.FullName); 
      company = fetch.GetAttributeValue(WellKnownAttributes.Company.CompanyName); 
     }
