An Azure Relay Service listener to accept and communicate with clients.

Syntax

IPWorksMQ.Azurerelayreceiver

Remarks

The AzureRelayReceiver class implements the listener role in the Azure Relay service. The class will connect to the server and listen for incoming connections. Once a connection is established data can be exchange freely in both directions allowing a flexible messaging environment.

Authenticating and Listening

Authentication to Azure Relay is performed using the Shared Access Key Name and Shared Access Key created from the Azure portal for the Relay. To begin listening for incoming connections set Listening to True.

When set to True the class will immediately attempt to make a connection to the Azure Relay Service and begin listening. The following properties are applicable when setting Listening:

• AccessKey (required)
• AccessKeyName (required)
• HybridConnection (required)
• NamespaceAddress (required)
• DefaultTimeout
• ForwardingHost
• ForwardingPort

To stop listening set Listening to False. To shutdown the server including existing connections call Shutdown.

Handling Connections

When a connection is made the ConnectionRequest event fires with information about the connecting client. From within this event the client connection may be accepted (default) or rejected.

If the client connection is accepted the ConnectionConnected and ConnectionReadyToSend events fire when the connection completes and is ready to send and receive data.

When data is received from the client the ConnectionDataIn event fires with the received data.

To send data to the client set ConnectionsDataToSend or call Send, SendFile, or SendText.

When the client disconnects the ConnectionDisconnected event fires. To initiate the client disconnection call Disconnect.

Handling HTTP Connections

Azure Relay also supports HTTP connections which follow a request/response model. When an HTTP request is received the HTTPRequest event fires with information about the request including the request body. Save the ConnectionId value obtained within HTTPRequest for use with SendHTTPResponse.

To send a HTTP response call SendHTTPResponse with the ConnectionId, status code and description, and any response day to be sent back to the client.

Forwarding Connections

The class supports forwarding incoming connection to a separate destination. This functionality allows AzureRelayReceiver to act as a proxy for incoming requests. When ForwardingHost and ForwardingPort are set anytime a connection is made the class will establish a separate connection to the ForwardingHost and forward all incoming traffic. Responses from the ForwardingHost are then automatically sent back over the connection.

When connection forwarding is used no special steps are needed to send or receive data. Data flows freely between the connected client and the ForwardingHost.

Note: Forwarding is not supported for HTTP requests.

Code Example (WebSockets)

Azurerelayreceiver listener = new Azurerelayreceiver(); listener.AccessKey = "9oKRDwjl0s440MlLUi4qHxDL34j1FS6K3t5TRoJ216c="; listener.AccessKeyName = "RootManageSharedAccessKey"; listener.NamespaceAddress = "myrelay.servicebus.windows.net"; listener.HybridConnection = "hc1"; listener.OnConnectionRequest += (s, e) => { Console.WriteLine("Connection Request From: " + e.RemoteAddress + ":" + e.RemotePort); e.Accept = true; }; listener.OnConnectionReadyToSend += (s, e) => { Console.WriteLine("Connection [" + e.ConnectionId + "] connected and ready to send and receive."); }; listener.OnConnectionDataIn += (s, e) => { Console.WriteLine("Received data from " + e.ConnectionId + ": " + e.Text); //echo the data back listener.SendText(e.ConnectionId, e.Text); Console.WriteLine("Echoed received data back"); }; listener.Listening = true; while (true) listener.DoEvents();

Code Example (HTTP)

Azurerelaylistener listener = new Azurerelaylistener(); listener.AccessKey = "9oKRDwjl0s440MlLUi4qHxDL34j1FS6K3t5TRoJ216c="; listener.AccessKeyName = "RootManageSharedAccessKey"; listener.NamespaceAddress = "myrelay.servicebus.windows.net"; listener.HybridConnection = "hc1"; listener.OnHTTPRequest += (s, e) => { Console.WriteLine("HTTP Request from " + e.RemoteAddress + ":" + e.RemotePort); Console.WriteLine("HTTP Method: " + e.RequestMethod); Console.WriteLine("HTTP Request: " + e.RequestData); myConnectionId = e.ConnectionId; }; //Send a response using the ConnectionId value from the HTTPRequest event listener.SendHTTPResponse(myConnectionId, 200, "OK", myResponseBody);

Config Method (AzureRelayReceiver Module)

Sets or retrieves a configuration setting.

Syntax

• Swift
• Objective-C

public func config(configurationString: String) throws -> String

- (NSString*)config:(NSString*)configurationString;

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Disconnect Method (AzureRelayReceiver Module)

This method disconnects the specified client.

Syntax

• Swift
• Objective-C

public func disconnect(connectionId: Int32) throws -> Void

- (void)disconnect:(int)connectionId;

Remarks

Calling this method will disconnect the client specified by the ConnectionId parameter.

DoEvents Method (AzureRelayReceiver Module)

Processes events from the internal message queue.

Syntax

• Swift
• Objective-C

public func doEvents() throws -> Void

- (void)doEvents;

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (AzureRelayReceiver Module)

Interrupts a synchronous send to the remote host.

Syntax

• Swift
• Objective-C

public func interrupt(connectionId: Int32) throws -> Void

- (void)interrupt:(int)connectionId;

Remarks

This property is called using the Connection ID if you wish to interrupt a connection and stop a file from uploading without disconnecting the client connected to the class. If you use SendFile to upload a file, the class will run synchronously on that Connection ID until it is completed.

PauseData Method (AzureRelayReceiver Module)

This method pauses data reception.

Syntax

• Swift
• Objective-C

public func pauseData(connectionId: Int32) throws -> Void

- (void)pauseData:(int)connectionId;

The DataIn event provides the data received from the client identified by the ConnectionId parameter.

The incoming data is provided through the Text parameter.

The DataFormat parameter identifies the encoding (if any) of the data. Possible value are:

The EOM parameter stands for End Of Message. By default the class will fire the DataIn event as data is received. Larger messages will be fragmented and will cause the event to fire multiple times. When EOM is true within the event this indicates the current fragment is also the final fragment of the message. The class may also be configured to buffer the message internally until the complete message is received. To enable this set BufferMessage to true.

The EOL parameter stands for End of Line. When LineMode is false, EOL will always be false. When LineMode is true, EOL will be True if the DataIn event fired because an EOL was received, and false if the DataIn event fired because MaxLineLength was reached.

ConnectionDisconnected Event (AzureRelayReceiver Module)

Fired when a WebSocket connection is disconnected.
