通过http后面的代理发布到Azure Service Bus

Question

我使用Azure ServiceBus API发布到Service Bus上。 sb协议在防火墙后面不起作用。 因此，我将ServiceBusEnvironment.SystemConnectivity.Mode设置为ConnectivityMode.Http。 只要我直接连接到互联网，这就有效。 即使在配置http代理之后，这在我的办公室也无法工作。 ServiceBus API是否存在问题？ 感谢您对此的帮助。

下面是我用过的一段代码....

    public static void Initialize()
    {
        // Using Http to be friendly with outbound firewalls
        ServiceBusEnvironment.SystemConnectivity.Mode =
            ConnectivityMode.Http;

        //InitializeQueue();
    }


    // The name of your queue
    public const string QueueName = "ordersqueue";

    public static NamespaceManager CreateNamespaceManager()
    {
        // Create the namespace manager which gives you access to
        // management operations
        var uri = ServiceBusEnvironment.CreateServiceUri(
            "sb", Namespace, String.Empty);
        var tP = TokenProvider.CreateSharedSecretTokenProvider(
            IssuerName, IssuerKey);
        return new NamespaceManager(uri, tP);
    }

    private static void InitializeQueue()
    {
        // Create the namespace manager which gives you access to 
        // management operations
        var namespaceManager = CreateNamespaceManager();

        // Create the queue if it does not exist already
        if (!namespaceManager.QueueExists(QueueName))
        {
            namespaceManager.CreateQueue(QueueName);
        }

        // Get a client to the queue
        var messagingFactory = MessagingFactory.Create(
            namespaceManager.Address,
            namespaceManager.Settings.TokenProvider);
        OrdersQueueClient = messagingFactory.CreateQueueClient(
            QueueName);
    }

下面是我得到的堆栈跟踪................................ ........... .................................................. ..

Answer 1

你得到的详细例外是什么？

根据我的经验，太多代理不支持默认配置的HTTP 1.1。 HTTP 1.1是Service Bus正常工作所必需的。

除此之外，我建议您查看本指南以解决与Service Bus的连接问题

Answer 2

微软本周发布了新的服务总线API。 请参阅下面的链接http://msdn.microsoft.com/en-us/library/windowsazure/hh667331.aspx#New_SB我已在服务总线1.8中测试了此问题。 还是一样的错误。 任何人都可以指导我是否微软已经解决了这个问题？

Answer 3

我是Windows Azure Service Bus团队的SDE。 请尝试发布指南。

另请注意，从SDK 1.7开始，Service Bus Messaging仅适用于支持POST分块的HTTP 1.1代理。 我们正在为此制定一个长期解决方案，即将推出的SDK 1.8允许Service Bus Relay通过使用HTTPS而不是POST分块来处理这些代理以及HTTP 1.0代理。

我们还意识到某些思科代理（可能还有其他代理）需要为尝试的任何IP地址连接提供名称地址。 我们正在为此制定长期解决方案。
