ibm bluemix - How to connect IBM Watson IOT using Paho MQTT javascript client? -
i trying connect ibm watson iot platform using paho mqtt javascript client mentioned in below example code.
var client = new messaging.client("myoqgid.messaging.internetofthings.ibmcloud.com", 8883, "myclientid_" + parseint(math.random() * 100, 10)); //gets called if websocket/mqtt connection gets disconnected reason client.onconnectionlost = function (responseobject) { //depending on scenario implement reconnect logic here alert("connection lost: " + responseobject.errormessage); }; //gets called whenever receive message subscriptions client.onmessagearrived = function (message) { //do push message received $('#messages').append('<span>topic: ' + message.destinationname + ' | ' + message.payloadstring + '</span><br/>'); }; //connect options var options = { username: api-key here, password: auth token here, timeout: 3, //gets called if connection has sucessfully been established onsuccess: function () { alert("connected"); }, //gets called if connection not established onfailure: function (message) { alert("connection failed: " + message.errormessage); } }; //creates new messaging.message object , sends hivemq mqtt broker var publish = function (payload, topic, qos) { //send message (also possible serialize json or protobuf or use string, no limitations) var message = new messaging.message(payload); message.destinationname = topic; message.qos = qos; client.send(message); } but not able connect. getting error: websocket connection 'ws://myorgidxyz.messaging.internetofthings.ibmcloud.com:8883/mqtt' failed: error during websocket handshake: net::err_connection_reset
please out there tried connecting ibm watson iot using paho mqtt client.
thank responses. based on responses have made changes in code.
<script type="text/javascript"> var clientid = 'a:myorgid:'+math.random().tostring(16).substr(2, 8); var client = new messaging.client("myoqgid.messaging.internetofthings.ibmcloud.com", 1883, clientid); //gets called if websocket/mqtt connection gets disconnected reason client.onconnectionlost = function (responseobject) { //depending on scenario implement reconnect logic here alert("connection lost: " + responseobject.errormessage); }; //gets called whenever receive message subscriptions client.onmessagearrived = function (message) { //do push message received $('#messages').append('<span>topic: ' + message.destinationname + ' | ' + message.payloadstring + '</span><br/>'); }; //connect options var options = { username: api-key here, password: auth token here, timeout: 3, //gets called if connection has sucessfully been established onsuccess: function () { alert("connected"); }, //gets called if connection not established onfailure: function (message) { alert("connection failed: " + message.errormessage); } }; //creates new messaging.message object , sends hivemq mqtt broker var publish = function (payload, topic, qos) { //send message (also possible serialize json or protobuf or use string, no limitations) var message = new messaging.message(payload); message.destinationname = topic; message.qos = qos; client.send(message); } client.connect(options); </script> you can see have made changes in clientid. ibm watson iot accept client ids in below format if not using watson iot libraries.
var clientid = 'a:orgid:'+randomstring;
if using ibm watson iot libraries client id can anything. implemented in node.js
