这在我之前也发生过，我认为这只是OpenId系统在ASP.NET Core中的工作方式的人工产物.我相信有一个Github问题，但我似乎找不到ATM.如果可以的话，我会四处看看并发布.

This happened to me previously as well, and I think this is just an artefact of how the OpenId system works in ASP.NET Core. I believe there was a Github issue for this but I can't seem to find it ATM. I'll have a look around and post it if I can find it.

在任何情况下，我都可以通过将事件添加到OpenId选项事件中来解决此问题，该事件仅重定向到首页"在任何远程故障上:

In any case, I was able to fix this by adding an event to the the OpenId options events that just redirects to "Home" on any remote failures:

options.Events = new OpenIdConnectEvents {
    // Your events here
    OnRemoteFailure = ctx => {
        ctx.HandleResponse();
        ctx.Response.Redirect("Home");
        return Task.FromResult(0);
    }
};

看看这是否适合您...

See if that works for you...
