成功獲取令牌后的OpenIdDict和ASP.NET Core：401（完全重現）

Question

我仍然在ASP.NET Core中使用OpenIdDict（憑證流）定期與OpenAuth進行斗爭，我更新到最新的OpenIdDict位和VS2017我可以在https://github.com/Myrmex/repro-oidang找到的舊示例代碼，完整的分步指導，以創建一個重要的啟動模板。 希望這對社區有用，可以幫助您開始使用簡單的安全方案，因此歡迎對該簡單示例代碼做出任何貢獻。

基本上，我遵循了OpenIdDict作者的憑證流示例，我可以在請求它時使用Fiddler獲取我的令牌：

POST http://localhost:50728/connect/token
Content-Type: application/x-www-form-urlencoded

grant_type=password&scope=offline_access profile email roles&resource=http://localhost:4200&username=zeus&password=P4ssw0rd!

問題是，當我嘗試使用此令牌時，我不斷獲得401，沒有任何其他提示：沒有異常，沒有記錄任何內容。 請求如下：

GET http://localhost:50728/api/values
Content-Type: application/json
Authorization: Bearer ...

這是我的相關代碼：first Startup.cs ：

        foreach (var claim in ticket.Principal.Claims)

Answer 1

正如本博文中所提到的 ，OpenIddict使用的令牌格式最近略有變化，這使得最新OpenIddict位發出的令牌與您正在使用的舊OAuth2驗證中間件版本不兼容。

遷移到AspNet.Security.OAuth.Validation 1.0.0 ，它應該工作。
