Question

在使用客户端UI连接生成器协商azure函数中的连接后，如何在azure函数中存在从azure signalR向特定用户发送数据的方法。在azure函数目标中存在。在UI中使用javascript的用户ID的任何完整解决方案用户ID如何可以传递给Azure Function并使用SignalR将数据发送给特定用户

谈判

 [FunctionName("negotiate")]
    public static SignalRConnectionInfo GetOrderNotificationsSignalRInfo(
        [HttpTrigger(AuthorizationLevel.Anonymous, "post")] HttpRequest req,
        [SignalRConnectionInfo(HubName = "notifications")] SignalRConnectionInfo connectionInfo)
    {            
        return connectionInfo;
    }

SignalR代码

 [FunctionName("PlacedOrderNotification")]
    public static async Task Run(
        [QueueTrigger("new-order-notifications")] OrderPlacement orderPlacement,
        [SignalR(HubName = "notifications")] IAsyncCollector<SignalRMessage> signalRMessages,
        ILogger log)
    {
        log.LogInformation($"Sending notification for {orderPlacement.CustomerName}");

        await signalRMessages.AddAsync(
            new SignalRMessage
            {
                
                Target = "productOrdered",
                Arguments = new[] { orderPlacement }
            });
    }

UI-Javascript

const connection = new signalR.HubConnectionBuilder()
            .withUrl('http://localhost:7071/api')
            .configureLogging(signalR.LogLevel.Information)
            .build();                      
        connection.on('productOrdered', (productOrdered));
        connection.onclose(() => console.log('disconnected'));
      
        console.log('connecting...');
        connection.start()
            .then(() => data.ready = true)
            .catch(console.error);
