Been trying to get feedback from my HUE system, heres the code that so far does not work, any help would be appreciated. Code runs once when page is being displayed.

var url = CF.widget("Hue_URL","HUE").label;
var socket = new TCPSocket();
socket.onConnect = function() {
prefix2 = 'GET /api/Y1Vpd5qwJVnjsRIdxFThJR0jsdcdaEvrQVe0NYM/lights'
postfix2 = ' HTTP/1.1\r\n'
try {
socket.write(prefix2+postfix2);
socket.write("HOST:+url+\r\n\r\n");
} catch(e) {
socket.close()
};
};
socket.onData = function() {
var info = socket.read();
var bright = info.split('"3":\{"state":\{"on":true,"bri":').pop().split(',"alert"')[0];
CF.widget("Hue_Level").label = bright;
};

Before saying it does not work, please tell us what you have done to rule things out and provide a bit more details.

Have you used the Postman utility from a desktop to make the requests as you are doing here?

Does your label have a url like this, for example:
http[colon][slash][slash]myhost.net//api/Y1Vpd5qwJVnjsRIdxFThJR0jsdcdaEvrQVe0NYM/lights

or one that is simply the host name, for example:
myhost.net

Please also note that an http request's response comes with multiple lines with CRLF (\r\n) separators , not just the json markup. Your use of 'split' worries me and is very 'fragile' to say the least.

Have you debugged using try/catch to confirm the socekt is working? Also I don't see a socket.close call except in the 'catch' block. There also needs to be one after reading all data, otherwise you will run out of sockets.
Again, have you debugged and review the Diagnostics log for errors such as out of sockets?

Have you done System.print on the variable named 'info' as things come back?

Thanks,
L.

I am trying to get and parse out the feedback from my Philipse Hue system. I have not tried Postman,
So I can do this command from a web browser and get data back,

http:[slash,slash]192.168.1.18:80/api/Y1Vpd5qwJVnjsRIdxFThJR0jxcrnZaEvrQVe0NYM/lights

I have tried to do an "info" dump and received no information. I did this by removing,
var bright = info.split('"3":\{"state":\{"on":true,"bri":').pop().split(',"alert"')[0];
and changed the last line to be
CF.widget("Hue_Level").label = info;

Right now I am not worried about parsing the data, work on that later.

This is an example I use in another program "Tablet Based" interface to get the feedback,
GET /api/Y1Vpd5qwJVnjsRIdxFThJR0jxcrnZaEvrQVe0NYM/lights HTTP/1.1\x0D\x0AHOST:{Set Hue IP}:80\x0D\x0A\x0D\x0A
Also I do not know where and how to do a "system print" for rdata..

I do have a close socket at the end, it just didn't realized it wasn't in the copy and paste.

I got it working,

socket.onConnect = function()
{
socket.write('GET /api/Y1Vpd5qwJVnjsRIdxFThJR0jxcrnZaEvrQVe0NYM/lights/3 HTTP/1.0\r\n\r\n')
socket.close;
};
socket.onData = function() {
var info = socket.read();
var bright = info.split('"bri":').pop().split(',')[0];
CF.widget("Hue_Level").label = bright;
socket.close;
};
socket.onIOError = function(e) {
socket.close()
};
socket.connect('192.168.1.18', 80, 30);

what is the best way to grab "Parse" the string, return data being,

bla bla bla, "on": true,"bri":125, "alert": "select", bla bla bla.
my code above does work and it grabs only the number value, but what's a better way?

Use the Philips HTTP Library. There are examples in the latest DEV Guide.

This will take care of reading all the HTTP response lines and leave you with the response body, i.e. the JSON content. You can use a JSON library to do JSON.parse
on the response body to build a Javascript object structure.

I took a minified one years ago from the web and wrapped it as a PEP Library.

Check your RC Mail.

I agree with Lyndel, use the HTTP library.
Depending on the kind of "post-processing" you're planning to do, adding a JSON library might be a lot of overhead.

If you only need a few single values, you can try to grab those with a regular expression.

E.g., this is how I grab the state of my Hue lights from my home automation system (Home-Assistant). It should work similar when talking to the Hue bridge directly:

var request = [];
function getState(entityId) {
    request[entityId] = new com.philips.HttpLibrary.HttpRequest();
    request[entityId].open("GET", "http://" + ha_host + ":" + ha_port + "/api/states/" + entityId, true);
    request[entityId].setRequestHeader("Authorization:", "Bearer " + ha_token);
    request[entityId].setRequestHeader("Content-Type:", "application/json");

    var state;
    request[entityId].onreadystatechange = function() {
        if (request[entityId].readyState == 4) {

            regex = /"state": "(\w+)"/;
            state = (request[entityId].responseText).match(regex)[1];
            if (state == "on") {
                CF.widget(entityId).setImage(IMG_ON);
                CF.widget(entityId).label = "on";
            } else {
                CF.widget(entityId).setImage(IMG_OFF);
                CF.widget(entityId).label = "off";
            }
        }
    }
    request[entityId].send();
};

M,

If you decide you want to use the RegExp, then that is much better than parsing using splits, etc...

i've sent the json libraries to your alternate email address as well as a modified version of the Philips Http Library that support transfer encoding of 'chunked'.
