Hey there,
i´ m very new to the REST-thing and getting in trouble by just trying to get a connection.
I tried out the following three functions:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js">
</script>
<script type="text/javascript">
function WebSocketTest()
{
if ("WebSocket" in window)
{
alert("WebSocket is supported by your Browser!");
// Let us open a web socket
var ws = new WebSocket("ws://192.168.178.52:8080/rest/items/FEG_HZ_Ist/state");
ws.onopen = function()
{
// Web Socket is connected, send data using send()
ws.send("Message to send");
alert("Message is sent...");
};
ws.onmessage = function (evt)
{
var received_msg = evt.data;
alert("Message is received...");
};
ws.onclose = function()
{
// websocket is closed.
alert("Connection is closed...");
};
}
else
{
// The browser doesn't support WebSocket
alert("WebSocket NOT supported by your Browser!");
}
}
function getState()
{
var request = $.ajax
({
type : "GET",
url : "http://192.168.178.52:8080/rest/items/FEG_HZ_Ist/state"
});
request.done( function(data)
{
console.log( "Success: Status=" + data );
});
request.fail( function(jqXHR, textStatus )
{
console.log( "Failure: " + textStatus );
});
}
function test()
{
var socket = $.atmosphere;
var request = new $.atmosphere.AtmosphereRequest();
request.url = "http://192.168.178.52:8080/rest/items?type=json";
request.contentType = "application/json";
request.headers = {"Accept": "application/json", "type": "json"};
request.transport = 'websocket';
request.fallbackTransport = 'long-polling';
request.onOpen = function () {
console.info("opOpen");
};
request.onMessage = function (message) {
console.info("onMessage", message);
console.info(message.responseBody);
};
var subSocket = socket.subscribe(request);
}
But in every try i get an other error:
FUnction 1: [HTTP/1.1 503 Jersey is not ready yet! 35ms]
Function 2: Firefox kann keine Verbindung zu dem Server unter ws://192.168.178.52:8080/rest/items/FEG_HZ_Ist/state aufbauen. / Firefox could not establish a connection to the server ws://192.168.178.52:8080/rest/items/FEG_HZ_Ist/state aufbauen
Function 3: TypeError: $.atmosphere is undefined
Could anyone help me, how i could get a correct working websocket connection?
Greetings
Dominic
