I have a module which I created in Crestron for Dreambox STB units in which I use the HTTP GET command with two carriage returns to execute over IP. How would this command be substituted in Pronto Script?
Demetris

Use the read method of the TCPSocket class.

You actually have to build socket script to issue HTTP protocol. Look at the Dev Guide for an example of how they are browsing google.com.

Still needs more work, will add word wrapping to it when i have the time. (following lyndels advise on some wrapping then)

This snippet will show you the current and the next item what is on the dreambox. I have this on my main tv screen on the pronto. Also have a button which shows the relevant info about the show that is playing. Which is basicly the same like below code, if someone wants that too let me know.

Change the ip, and make sure your pronto is allowed to go to the website withou authorisation. Hope this works on other dreamboxes too (depending on your build)

var result = "";
var socket = new TCPSocket(false);
var t1,t2,t3,t4,t5;
var event1,event2;
var descrip1, descrip2;

socket.onConnect = function()
{
socket.write("GET /cgi-bin/channelinfo HTTP/1.1\r\n");
socket.write("Accept: */*\r\n");
socket.write("Host: 192.168.1.99\r\n");
socket.write("\r\n");
};

socket.onData = function()
{
result += socket.read(5000,1000);

t0 = result.indexOf("class=\"time\">", 0)+13;
t10 = result.indexOf("/span>",t0)-1;
tijd1 = result.substring(t0,t10);

t1 = result.indexOf("class=\"event\">", 0)+14;
t2 = result.indexOf("/span>",t1)-1;
event1 = result.substring(t1,t2);
CF.widget("channel1").label=event1;

t4 = result.indexOf("class=\"description\">", t2)+20;
t5 = result.indexOf("/span>",t4)-1;

t6 = result.indexOf("class=\"event\">", t5)+14;
t7 = result.indexOf("/span>",t6)-1;
event2 = result.substring(t6,t7);
CF.widget("channel2").label=event2;

};


socket.onClose = function()
{
};


socket.onIOError = function(e)
{
};


if(socket.connected == false)
{
socket.connect('192.168.1.99', 80, 3000);
};

One change I would recommend here.

socket.write("GET /cgi-bin/channelinfo HTTP/1.0\r\n");

Why? Because HTTP 1.0 automatically closes sockets at the end of the request. You'll thank me in a month or so. ;-)

Thanks for the tip...:)

Snelvuur,

Thanks for the Code. It works great on my 7020 Dreambox. If you also have the code for the "info" of a show I would appreciate when you could publish it.

Thx,
Rob

Update - Http 1.0 was supposed to close sockets but I've found cases where some servers don't (Escient Fireball PC). So, you should also put in a request header in the body as a hint.

Connection: close\r\n

Happy Holidays

@rdvoort: i'll put it here too, but it does not have word wrapping yet. Only wraps at a certain amount of characters.

@snelvuur
I have modified your script and also tried to add word rapping (adjust value "a" for the width of your panel). Probably not the most efficient way to do it but unfortunately I don't have any experience with Javascript. My program knowledge stops at programming in Fortran 77 many years ago ;-)

The only problem I currently have is that special characters like for example "ö" or "ü" do not show up correctly. Not sure if someone knows a solution for this problem.

me neither, although lyndel pointed out [Link: snippets.dzone.com] this snippet. Which basicly would be a bit better (i think) not sure.

Here's a function to convert utf-8 to ascii i found somewhere on the web:

System.print(utfconf(descrip1));

prints the correct special characters on the debug panel. Unfortunately if you try to
assign the converted string to a label, there are the wrong chars again.

this seems to be a bug in the firmware as Barry Gordon mentioned in thread:

function utfconv(utftext)
{
var string = "";
var i = 0;
var c = c1 = c2 = 0;

while ( i < utftext.length ) {
c = utftext.charCodeAt(i);

if (c < 128) {
string += String.fromCharCode(c);
i++;
}
else if((c > 191) && (c < 224)) {
c2 = utftext.charCodeAt(i+1);
string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));

}
