-
-// Only expose a single object name in the global namespace.
-// Everything must go through this module. Global Paho.MQTT module
-// only has a single public function, client, which returns
-// a Paho.MQTT client object given connection details.
-
-/**
- * Send and receive messages using web browsers.
- *
- * This programming interface lets a JavaScript client application use the MQTT V3.1 or
- * V3.1.1 protocol to connect to an MQTT-supporting messaging server.
- *
- * The function supported includes:
- *
- *
Connecting to and disconnecting from a server. The server is identified by its host name and port number.
- *
Specifying options that relate to the communications link with the server,
- * for example the frequency of keep-alive heartbeats, and whether SSL/TLS is required.
- *
Subscribing to and receiving messages from MQTT Topics.
- *
Publishing messages to MQTT Topics.
- *
- *
- * The API consists of two main objects:
- *
- *
{@link Paho.MQTT.Client}
- *
This contains methods that provide the functionality of the API,
- * including provision of callbacks that notify the application when a message
- * arrives from or is delivered to the messaging server,
- * or when the status of its connection to the messaging server changes.
- *
{@link Paho.MQTT.Message}
- *
This encapsulates the payload of the message along with various attributes
- * associated with its delivery, in particular the destination to which it has
- * been (or is about to be) sent.
- *
- *
- * The programming interface validates parameters passed to it, and will throw
- * an Error containing an error message intended for developer use, if it detects
- * an error with any parameter.
- *
- * Example:
- *
- *
-client = new Paho.MQTT.Client(location.hostname, Number(location.port), "clientId");
-client.onConnectionLost = onConnectionLost;
-client.onMessageArrived = onMessageArrived;
-client.connect({onSuccess:onConnect});
-
-function onConnect() {
- // Once a connection has been made, make a subscription and send a message.
- console.log("onConnect");
- client.subscribe("/World");
- message = new Paho.MQTT.Message("Hello");
- message.destinationName = "/World";
- client.send(message);
-};
-function onConnectionLost(responseObject) {
- if (responseObject.errorCode !== 0)
- console.log("onConnectionLost:"+responseObject.errorMessage);
-};
-function onMessageArrived(message) {
- console.log("onMessageArrived:"+message.payloadString);
- client.disconnect();
-};
