问题
I used Azure ServiceBus API to publish onto Service Bus. The sb protocol does not work behind the firewall. Hence I set ServiceBusEnvironment.SystemConnectivity.Mode to ConnectivityMode.Http. This was working as long as I was directly connected to the internet. This wouldnt work in my office, even after configuring the http proxy. Is there an issue with the ServiceBus API? Appreciate your help on this.
Below is the piece of code that I used....
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);
}
Below is the stack trace I get................................ ...............................................................

回答1:
What is the detailed exception you get?
In my experience, too many proxies do not support HTTP 1.1 by their default configuration. HTTP 1.1 is necessary for Service Bus to work properly.
Other than this I suggest you to check this guide to troubleshoot connectivity to Service Bus

Microsoft has released new service bus API this week. See the links below http://msdn.microsoft.com/en-us/library/windowsazure/hh667331.aspx#New_SB I have tested this issue in service bus 1.8. Still the same error. can anyone please guide me whether microsoft has fixed this issue ?
回答3:
I'm an SDE on the Windows Azure Service Bus team. Please attempt the guide posted.
Also be aware that as of SDK 1.7, Service Bus Messaging only works with HTTP 1.1 proxies that support POST chunking. We are working on a long-term solution to this and the upcoming SDK 1.8 allows Service Bus Relay to work on these proxies and also over HTTP 1.0 proxies by using HTTPS rather than POST chunking.
We are also aware that certain Cisco proxies (and perhaps others) require name addresses for any IP address connection that is attempted. We are working on a long term solution to this.
