托管到IIS时，Blazor客户端发信号器无法正常工作 [英] Blazor Client Side Signalr not working when Hosting to IIS

问题描述

有没有人能指出我正确的方向?

Is there any one who can point me in the right direction?

将我的Blazor客户端应用程序托管到IIS时，信号器无法正常工作. 在带有IIS的visual studio中，它可以按预期工作. 我确实设置了IIS，并按照Microsoft文档中的指示部署了应用程序.

When hosting my Blazor Client Side application to IIS the signalr is not working. In visual studio with IIS express it work as expected. I did setup IIS and deployed the application as indicated in the Microsoft documents.

没有控制台错误，并且在IIS中托管时，集线器返回状态代码200.

There is no console errors and the hub returns status code 200 when hosting in IIS.

提前谢谢

推荐答案

IIS默认情况下未启用Websocket支持.它是在IIS 8中引入的，必须从Windows的可选功能中启用:

Websocket support is not enabled by default on IIS. It was introduced in IIS 8, and has to be enabled from windows' optional features: https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support

可选功能-> IIS-> WWW服务-> App Dev功能-> Websocket协议

Optional features -> IIS -> WWW services -> App Dev Features -> Websocket protocol
