讓 ClaimsResponse 與 DotNetOpenId 一起工作的秘訣是什麼？
讓 ClaimsResponse 與DotNetOpenId一起工作的秘訣是什麼？
例如，在這段程式碼（來自Scott Hanselman 的部落格）中，ClaimsResponse 對象應該有很多不錯的小東西，例如“暱稱”和“電子郵件地址”，但 ClaimsResponse 對象本身是“null”：
OpenIdRelyingParty openid = new OpenIdRelyingParty(); if (openid.Response != null) { // Stage 3: OpenID Provider sending assertion response switch (openid.Response.Status) { case AuthenticationStatus.Authenticated: ClaimsResponse fetch = openid.Response.GetExtension(typeof(ClaimsResponse)) as ClaimsResponse; string nick = fetch.Nickname; string homepage = openid.Response.ClaimedIdentifier; string email = fetch.Email; string comment = Session["pendingComment"] as string; string entryId = Session["pendingEntryId"] as string; if (String.IsNullOrEmpty(comment) == false && String.IsNullOrEmpty(entryId) == false) { AddNewComment(nick, email, homepage, comment, entryId, true); } break; } }起初，我認為這是因為我沒有使用“ClaimsRequest”重定向到提供者……但使用此程式碼重定向到 OpenId 提供者仍然無濟於事：
OpenIdRelyingParty openid = new OpenIdRelyingParty(); IAuthenticationRequest req = openid.CreateRequest(openid_identifier.Text); ClaimsRequest fetch = new ClaimsRequest(); fetch.Email = DemandLevel.Require; fetch.Nickname = DemandLevel.Require; req.AddExtension(fetch); req.RedirectToProvider();我究竟做錯了什麼？或者其他開發者是否經歷過同樣的痛苦？
你的程式碼看起來不錯。但請注意，並非所有 OP 都支持您正在使用的 sreg 擴展。如果您正在驗證的 OP 不支持它，那麼響應擴展將為您所看到的 null。所以空檢查總是一個好主意。
myopenid.com 支持 sreg，如果您正在尋找要測試的 OP。
我不知道您是否解決了問題，但經過數小時的努力，我找到了解決方案。實際上，您需要更改您的 web.config 文件以聲明電子郵件，這裡的全名是 web.config，它適用於我。我從 nerddinner 項目下載了它。實際上，我複制了除 web.config 之外的所有內容，但沒有收到電子郵件欄位。所以後來我發現還有其他問題。我從 nerddinner 項目中複製了 web.config，一切正常。
這是文件，如果你不想去 nerddinner 項目。
