[appengine-java] Re: Channel API reconnect after token timeout
Hey, I am also experiencing this problem. Trying to reconnect from the client side after the token expiries with no luck. I'm using the gwt-gae-channel library on client side. I was just wondering if you have found a solution to this problem? Thanks Joe -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Channel API reconnect after token timeout
I've received a reasonable workaround from Google Enterprise Support: You can use a timer on the client side to renew the token before it expires. This will work somehow... -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Channel API reconnect after token timeout
Hi there,
(First I'm french... so please apologize for my english mistakes)
I'm working with GAE, using python, and get the same problem as you, to
refresh tokens for users allready connected
just to say... I've started a chat-script, by using a login script, with
session in python:
from gaesessions import get_current_session
for example, calling the session using :
def Guestbook(message, tokens=None):
if not tokens:
tokens = memcache.get('tokens')
if tokens:
session = get_current_session()
user=session.get('user_name')
But each time I restarted the server, the user wasn't automatically
reconnected... which is quite the same problem as yours
here is my issue, from client-side :
!DOCTYPE html
html
head
meta charset=utf-8/
titleGAE Test-Channel-API/title
style type=text/css
#userlist {
margin: 5px 0 0 0;
padding: 5px;
border: 1px solid #ccc;
height: 320px;
overflow: auto;
font-size:12px;
}
/style
script src=/_ah/channel/jsapi/script
script src=/jquery.js/script
script
reco_count=0;
$(document).ready(
function() {
var token;
function get_token() {
if (token) {return false;} ;// try to prevent duplicate entry
$.get('/get_token', function(data){
if (data) {
reco_count=0;
token = data;
document.getElementById('userlist').innerHTML=token + connected!br
openChannel();
}
else
{
document.getElementById('userlist').innerHTML=document.getElementById('userlist').innerHTML+Can't
connect... Channel Full ? !br;
}
});
setTimeout(function() {if (!token) {Reconnect();} },4000 ); // retry to
connect
}
get_token();
function Reconnect() {
setTimeout(function() {if (token) {reco_count=0; return false;} else
{reco_count=reco_count+1;
document.getElementById('userlist').innerHTML=Server error !brTrying to
reconnect (+reco_count+)... fail br; get_token(); }; }, 4000);
}
function onClose() {
token=null;
Reconnect();
}
function onError() {
token=null;
Reconnect();
}
function onOpen() {
$.post('/open', {'token': token});
}
function onMessage(m) {
// getting message
// TODO
}
function openChannel() {
var channel = new goog.appengine.Channel(token);
var handler = {
'onopen': onOpen,
'onmessage': onMessage,
'onerror': onError,
'onclose': onClose
};
channel.open(handler);
}
$(window).bind('beforeunload', function() {
if (token) {
document.getElementById('userlist').innerHTML=document.getElementById('userlist').innerHTML+token
+ disconnected!br
$.post('/del_token', {'token': token});
}
})
}
)
/script
/head
body
div id=userlist style=position:relative;top:0px;left:0px;/div
/body/html
Hoping it will help some,
Rgds,
guibs

[appengine-java] Re: Channel API reconnect after token timeout
...finally figured out how to properly remove the iframe from a GWT app:
public static native void removeChannelApi() /*-{
var child = $wnd.parent.document.getElementById(wcs-iframe);
if ( child != null ) {
child.parentNode.removeChild(child);
}
}-*/;
