Cross domain problem

[duuliy]

The 1.0.2 version has no System.Web.Cors. HTTP's cros is also not cross domain....webpack's proxy also can not. Now I want to cross the domain. What do you do?

What error are you getting?

[duuliy]

There is no problem when homology does not require cross domain. However, cross domain development environment can not get the value of ProgressReported callback, and the time to connect to signalr will be very long. The print signalr description is successfully referenced. The client code is as follows: var connection; // 进度处理 console.log(signalR) connection = new signalR.HubConnectionBuilder() .configureLogging(signalR.LogLevel.Warning) .withUrl("/test/progress", signalR.HttpTransportType.WebSockets) .build();

    connection.on("ProgressReported", function(p) {
      alert(123123);
      console.log(p)
    });

  connection.start().catch(function(err) {
    console.log("建立连接异常：" + err)
  });

There is no problem when homology does not require cross domain. However, cross domain development environment can not get the value of ProgressReported callback, and the time to connect to signalr will be very long. The print signalr description is successfully referenced. The client code is as follows: var connection; // 进度处理 console.log(signalR) connection = new signalR.HubConnectionBuilder() .configureLogging(signalR.LogLevel.Warning) .withUrl("/test/progress", signalR.HttpTransportType.WebSockets) .build(); connection.on("ProgressReported", function(p) { alert(123123); console.log(p) }); connection.start().catch(function(err) { console.log("建立连接异常：" + err) });

So everything works but it just takes long? What do the logs say? Turn on debug logs.

Thanks, it has been solved, that is, we can't use webpack's proxy to cross domain.
