azure-servicebus- Haskell wrapper over Microsoft Azure ServiceBus REST API

Safe HaskellNone




__ deprecated __ Use Network.MicrosoftAzure.ServiceBus.Queue instead.

Provides API to pull from and push to ServiceBus queue Please refer to Service Bus Rest API for information on the API provided by Microsoft Service bus.

Simple example for how to use this library is as below

 import Web.WindowsAzure.ServiceBus.Queue
 import Web.WindowsAzure.ServiceBus
 import qualified Data.ByteString.Char8 as C

queueName = queueName
 sbNamespace = namespace
 sbIssuerKey = C.pack 1287361251262as=
 sbIssuerName = C.pack owner

sbinfo = SBInfo sbNamespace sbIssuerName sbIssuerKey
 message = C.pack Hello from Haskell

main = do
   sbContext <- sbContext sbinfo
   enQueueBS queueName message sbContext
   res <- deQueue queueName 30 sbContext
   print res

see examples (available as a part of distribution) for a more detailed example.



data QLockedMsgInfo Source

QLockedMsgInfo provides Information of the locked message from a queue.


Pushing data to Queue

enQueueBS :: String -> ByteString -> SBContext -> IO ()Source

publish a message containing ByteString to queue.

The following publishes a strict bytestring bs to queue q\

 enQueueBS q bs ctx

enQueueLBS :: String -> ByteString -> SBContext -> IO ()Source

publish a message containing ByteString to queue

The following publishes a lazy bytestring ,lbs, to queue q,

 enQueueLBS q lbs  ctx

Reading data from Queue

deQueue :: String -> Int -> SBContext -> IO ByteStringSource

Reads and deletes the message from a queue.

In order to destructively read the latest message from the queue (with a time out of n seconds),

deQueue queueName n context Note that the timeout can be at the most 55 seconds. This silently ignores the timeouts greater than 55

peekLockQueue :: String -> Int -> SBContext -> IO (LockedMsgInfo, ByteString)Source

Peek Lock Message from a Queue. Non-Destructive Read.

Atomically retrieves the next message from a queue and locks it for further processing. The message is guaranteed not to be delivered to other receivers (on the same subscription) during the duration of the lock.

Refer ServiceBus documentation for semantics of the underlying REST API.
