ASP.NET-CORE 2.2 SignalR CORS [英] ASP.NET-CORE 2.2 SignalR CORS

问题描述

我对ASP.Net Core 2.2和SignalR有问题.我在asp.net核心和Angular之间使用SignalR.当我使用Asp.net core 2.0时，一切正常.但是，当我将asp.net core 2.2与相同的代码一起使用时，相同的类会出现cors错误.

I have a problem with ASP.Net Core 2.2 and SignalR. I am using SignalR between asp.net core and Angular. When i am using Asp.net core 2.0, everything work fine. But when i am using asp.net core 2.2 with same code, same classes am getting a cors error.

警告:CORS协议不允许同时指定通配符(任何)来源和凭据.如果需要支持凭据，请通过列出各个来源来配置策略.

Warning: The CORS protocol does not allow specifying a wildcard (any) origin and credentials at the same time. Configure the policy by listing individual origins if credentials needs to be supported.

我该如何解决这个问题?

How can i solve this problem?

谢谢

推荐答案

                //.AllowAnyOrigin()
                .AllowAnyMethod()
                .AllowAnyHeader()
                .AllowCredentials()
                .SetIsOriginAllowed((host) => true) //for signalr cors                
                    );
        });
