StompLib

StompLib is a Qt library for clients communicating with the Stomp protocol. It includes the following functionality:

A communication frame is modelled in the class StompFrame.

In the StompFrameCreator class:

1. Create a CONNECT frame
2. Create a STOMP frame
3. Create a SUBSCRIBE frame
4. Create a MESSAGE frame
5. Create a UNSUBSCRIBE frame
6. Create a DISCONNECT frame

In the StompFrameParser class the parsing of STOMP text messages is implemented. The method responsible for this is called parseFromTextMessage. The method implements unescaping of special symbols.

The StompClient class encapsulates a QWebSocket object that communicates with the server. Various methods for communicating through the web socket as well as signals and slots are implemented.

Example usage:

Connecting to the server

m_StompClient->setUrl(server_url);

m_StompClient->connectToServer();

Connecting through STOMP

StompFrameCreator stompFrameCreator;

auto connectFrame = stompFrameCreator.createConnectFrame("1.2", "", "", "", 10000, 10000);

m_StompClient->sendFrame(connectFrame);

Subscribing to a topic

StompFrameCreator stompFrameCreator;

QString topicName = "/topic/myTopic";

auto subscribeFrame = stompFrameCreator.createSubscribeFrame(1, topicName, "auto");

m_StompClient->sendFrame(subscribeFrame);

Sending text message

auto publishFrame = stompFrameCreator.createSendTextFrame("/controller/address", message);

m_StompClient->sendFrame(publishFrame);

Unsubscribe from topic

StompFrameCreator stompFrameCreator;

auto unsubscribeFrame = stompFrameCreator.createUnsubscribeFrame(1);

m_StompClient->sendFrame(unsubscribeFrame);

Close connection to STOMP

auto disconnectFrame = stompFrameCreator.createDisconnectFrame(1);

m_StompClient->sendFrame(disconnectFrame);

Receiving message from server

connect(m_StompClient, &StompClient::stompMessageReceived, this, &MyClass::stompReceivedSlot);
