websocket与android应用程序的连接

尝试连接时出错:

ReactNativeJS: [12:52:08 GMT+0000 (GMT)] SignalR: Client subscribed to hub 'chathub'. ReactNativeJS: [12:52:08 GMT+0000 (GMT)] SignalR: Negotiating with 'http://10.0.2.2:50069/chathub/signalr/negotiate?clientProtocol=1.5&connectionData=%5B%7B%22name%22%3A%22chathub%22%7D%5D'. ReactNativeJS: 'SignalR error: Error during negotiation request.', '' ReactNativeJS: Failed ReactNativeJS: [12:52:08 GMT+0000 (GMT)] SignalR: Stopping connection.

服务器:

public class ChatHub : Hub
{
    public async Task SendMessage(string user, string message)
    {
        await Clients.All.SendAsync("ReceiveMessage", user, message);
    }
}

在启动.cs(省略未绑定的条目)

public void ConfigureServices(IServiceCollection services)
{

    services.AddSignalR();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, DataContext context)
{
    // global cors policy
    app.UseCors(x => x
        .AllowAnyOrigin()
        .AllowAnyMethod()
        .AllowAnyHeader()
        .AllowCredentials());

    app.UseMvc();

    app.UseSignalR(routes =>
    {
        routes.MapHub<ChatHub>("/chatHub");
    });
}

本地反应:

import signalr from 'react-native-signalr';

export default class Settings extends Component{

  componentDidMount() {
    //This is the server under /example/server published on azure.
    const connection = signalr.hubConnection('http://10.0.2.2:50069/chathub');
    connection.logging = true;

    const proxy = connection.createHubProxy('chatHub');
    //receives broadcast messages from a hub function, called "helloApp"
    proxy.on('SendMessage', (argOne, argTwo, argThree, argFour) => {
      console.log('message-from-server', argOne, argTwo, argThree, argFour);
      //Here I could response by calling something else on the server...
    });

    // atempt connection, and handle errors
    connection.start().done(() => {
      console.log('Now connected, connection ID=' + connection.id);

      proxy.invoke('sendMessage', 'Hello Server, how are you?', 'ffff')
        .done((directResponse) => {
          console.log('direct-response-from-server', directResponse);
        }).fail(() => {
          console.warn('Something went wrong when calling server, it might not be up and running?')
        });

    }).fail(() => {
      console.log('Failed');
    });

    //connection-handling
    connection.connectionSlow(() => {
      console.log('We are currently experiencing difficulties with the connection.')
    });

    connection.error((error) => {
      const errorMessage = error.message;
      let detailedError = '';
      if (error.source && error.source._response) {
        detailedError = error.source._response;
      }
      if (detailedError === 'An SSL error has occurred and a secure connection to the server cannot be made.') {
        console.log('When using react-native-signalr on ios with http remember to enable http in App Transport Security https://github.com/olofd/react-native-signalr/issues/14')
      }
      console.debug('SignalR error: ' + errorMessage, detailedError)
    });
  }
    render(){
        return(
          <View style={{flex: 1}}>
        </View>
        )
    }
}

我做了一切应该做的事,但我不想做任何联系。我在用10个窗户。

也许我忘了密码里的东西?
