Gmail OpenID用戶不識別

Question

我在我的MVC3應用程序中設置了OpenID，我使用的是Gmail登錄。看到我的身份驗證表格。我正在實施代碼http://weblogs.asp.net/haithamkhedre/archive/2011/03/13/openid-authentication-with-asp-net-mvc3-dotnetopenauth-and-openid-selector.aspx

當使用IIS express在本地運行時，一切正常，我可以看到else語句和buttonGreen代碼。一旦我將它部署到網絡上，它會跳轉到「if（String.IsNullOrEmpty（Model.UserName））」，然後我將以「新用戶，註冊」代碼結束。顯示model.OpenID。 該代碼與MyOpenId（我已放棄，由於其他問題）聯機工作。

成員資格數據庫已經卷入主數據庫，用戶通過OpenID登錄本地創建，分配給角色，然後將數據庫推送到網絡。我在兩週前使用了最新的DotANetOpenAuth。我使用DotANetOpenAuth.Core，DotANetOpenAuth.OpenId和DotANetOpenAuth.OpenId.RelyParty。

<form action="Authenticate?ReturnUrl=@HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"])" method="post" id="openid_form"> 
<input type="hidden" name="action" value="verify" /> 
<div> 
    <fieldset> 
     <legend>Login using OpenID</legend> 
     <div class="openid_choice"> 
      <p> Please click your account provider:</p> 
      <div id="openid_btns"></div> 
     </div> 
     <div id="openid_input_area"> 
      @Html.TextBox("openid_identifier") 
      <input type="submit" value="Log On" /> 
     </div>

       OpenID is service that allows you to log-on to many different websites using a single 
       indentity. Find out <a href="http://openid.net/what/">more about OpenID</a> and

     </noscript> 
     <div> 
      @if (Model != null) 
      { 
       if (String.IsNullOrEmpty(Model.UserName)) 
       { 
        <div class="editor-label"> 
         @Html.LabelFor(model => model.OpenID) 
        </div> 
        <div class="editor-field"> 
         @Html.DisplayFor(model => model.OpenID) 
        </div> 
        <p class="button"> 
         @Html.ActionLink("New User, Register", "Register", new { OpenID = Model.OpenID }) 
        </p> 
       } 
       else 
       { 
       //user exist 
        <p class="buttonGreen"> 
        <a href="@Url.Action("Index", "TalPro")">Welcome @Model.UserName, Continue... </a> 
        </p> 
       } 
      } 
     </div>

爲什麼會在本地工作，但無法在網絡上？

謝謝。

若要進一步優化問題。在IIS Express Model.UserName本地託管時設置正確，登錄成功。在Web上託管時（DiscountASP IIS 7.0），Model.UserName未設置並且登錄失敗。問題是爲什麼？這是否與IIS有關？它與Cookie有關嗎？我將如何解決它？

Google向不同的OpenID領域發佈不同的OpenID聲明標識符。當您在本地登錄時，您的領域可能是'localhost'，但在生產中它明顯不同，因此Google會發布不同的OpenID，導致您無法識別用戶。谷歌在這方面相當獨特。

我建議您從您的生產領域獲得您的索賠ID。
