我的代码与.net core 2.0完美配合。我不确定出了什么问题。应用程序在授权期间抛出错误。错误消息和下面的启动类代码。

我认为您错过了身份验证中间件：app.UseAuthentication（）。

请试试这个：

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {
            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();
            app.UseCors(
                builder => builder
                .AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()
            );
            app.UseAuthentication();
            app.UseMvc();
            app.UseResponseCompression();
        }
