我对OpenIdDict身份验证服务器有一些问题。我将其设置为密码流，也将自定义实体用于授权和令牌实体。当我第一次尝试登录令牌端点时，在我的应用程序启动后，它可以正常工作。在调试日志中，我看到此消息。
m.insertBefore( "System.out.println(outer_field);");但是所有其他将来的请求（在重新启动项目之前）都引发InvalidOperationException：InvalidOperationException：无法从此端点返回授权或令牌响应。 找到此错误的描述之后，我再次看到调试输出日志，发现除了第一个请求之外，所有请求中都没有来自OpenIddictHandler的消息。调试输出为：

如您所见，没有关于OpenIddictHandler的消息。我不知道为什么会这样，将不胜感激。
这是我的OpenIdDict配置。

非常感谢！
答案 0 :(得分：0)
我发现了错误，这很糟糕。我在app.UseAuthentication（）之前注册app.UseMvc（）; Mvc操作后在Startup.cs中调用OpenIdDict中间件。
