Asp .Net Core 2 + SignalR(1.0.0-alpha2-27025)+/signalr/negotiate 404错误 [英] Asp .Net Core 2 + SignalR (1.0.0-alpha2-27025) + /signalr/negotiate 404 Error

问题描述

我将SignalR添加到ASP .Net Core 2应用

I add SignalR to ASP .Net Core 2 app

软件包

• "Microsoft.AspNetCore.All" Version ="2.0.0"
• "Microsoft.AspNetCore.SignalR" Version ="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Client" Version ="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Client.Core" Version ="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Common" Version ="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Core" Version ="1.0.0-alpha2-27025"

• "Microsoft.AspNetCore.All" Version="2.0.0"
• "Microsoft.AspNetCore.SignalR" Version="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Client" Version="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Client.Core" Version="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Common" Version="1.0.0-alpha2-27025"
• "Microsoft.AspNetCore.SignalR.Core" Version="1.0.0-alpha2-27025"

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddSignalRCore();
    services.AddSignalR();
}

和

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, IServiceProvider serviceProvider)
    app.UseSignalR(routes =>
    {
        routes.MapHub<ManageHub>("manageHub");
    });
}

url:port/signalr ， url:port/signalr/negotiate ... 返回404

url:port/manageHub 返回带有需要连接ID"的400

url:port/manageHub return 400 with "Connection ID required"

我找不到.MapSignalR()

I not found .MapSignalR()

如何在ASP .Net Core中使用SignalR?

推荐答案

您似乎正在使用旧客户端.用于ASP.NET Core的SignalR不再使用/negotiate 端点.新的SignalR服务器与旧的客户端不兼容，新的客户端与旧的SignalR服务器不兼容.看看样本

You seem to be using the old client. SignalR for ASP.NET Core does not use the /negotiate endpoint anymore. The new SignalR server is not compatible with old client and the new clients are not compatible with the old SignalR server. Take a look at the announcement and samples
