Getting HTTP/1.1 204 No Content when I try to push the message

[prasad iyer]

I have published the app on Google Chrome Webstore. And created native app & chrome app on google console.
I am able to get the access token for the sending the message the problem is when I try to the push the message over the cloud I get error HTTP/1.1 204 No Content ( I am getting null content). And even the notification is not displayed on the console. Does anyone have any idea what am I missing.


Following is the code

        java.util.Map<String, String> payload = new java.util.HashMap<String, String>();
        payload.put("channelId", channelId);
        payload.put("subchannelId", subchannelId);
        payload.put("payload", message);
        System.out.println("Access Token : " + token.getAccess_token());
        HttpClient client = (HttpClient) ctx.getBean("httpclient");
        PostMethod method = new PostMethod(ClientConfig.messageurl);
        method.setRequestHeader("Host", "googleapis.com");
        method.setRequestHeader("Content-Type", "application/json");
        method.setRequestHeader("Authorization", token.getToken_type() + " "
                + token.getAccess_token());
       
        Gson gson = new Gson();
        final String _payload = gson.toJson(payload).toString();
        System.out.println(_payload);
        RequestEntity entity = new ByteArrayRequestEntity(_payload.getBytes());
        method.setRequestEntity(entity);
        try {
            int rc = client.executeMethod(method);
            if ( rc == 400){
               
                System.out.println("something went wrong with the token... refreshing ");
                System.out.println(method.getResponseBodyAsString());
                token.setAccess_token(null);
                sendMessage(message, channelId, subchannelId, retryvalue++);
            }
            if (rc != HttpStatus.SC_OK) {
                System.out.println(method.getResponseBodyAsString());
                throw new RuntimeException(method.getStatusLine().toString());
            }

        } catch (HttpException e) {
            throw new RuntimeException(e);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }

thanks

204 No Content is the header that says the post actually happened successfully. Do you get the notification delivered into the app?

I wonder why I don't get response in Chrome App. I have registered both Chrome App and Native App under one project. Chrome App is shamelessly copied from guestbook-app on Github. By the way thanks for clearing my doubt about 204 response code. I would make those changes on the server

Some quick checks:

- is the browser profile where the the app is installed signed into Google? (Menu -> "Signed into ...")?

- in that browser, if you open a tab and navigate to "chrome://sync-internals/", then click "Notifications", does it say State: INVALIDATIONS_ENABLED on top?

- are you using the ChannelId that this app returned from getChanngeId() API?

[prasad iyer]

Hi Dimitry,
 - The user is signed into Google
 - chrome://sync-internals > Notification says State: TRANSIENT_INVALIDATION_ERROR
 - To send the message I use the channelId returned by the browser when the chrome app starts.

Yesterday I was trying on my windows machine. Today I am trying on the macbook.
thank you

[Dmitry Titov]

TRANSIENT_INVALIDATION_ERROR is not a good thing. Does it stay this way all the time or goes away after restarting Chrome? It sounds like the user is not really signed in properly...

Yes it stays in that state all the time I have restarted Chrome a lot of time. Removed and redeployed the Chrome App too.
I am signed into Chrome with my google credentials. Is there anything I can do to make State: TRANSIENT_INVALIDATION_ERROR go away. The chrome version is Version 31.0.1650.63.

I have 2 step verification on my account do you think that would be a problem. It won't ask me for the 6 digit code for next 30 days though.

What kind of network are you on? Could you send a screenshot of both your about:sync main tab and the notifications tab?

We have LAN and it has firewall. All the http/https connections are
made through the proxy. Is there a way to configure XMPP on chrome
browser to use Http/Https.

Could you capture network traffic and send it to me? I'll try to see what's going on:

- Sign out of chrome.

- navigate to about:net-internals, this will start capturing network events 

- sign in to chrome and wait for few seconds. 

- stop capture and export events on about:net-internals.

There were couple of issues I faced and thanks to everyone to help me get the application working. I would summarize the things I did for building the application.

1. Google Cloud Console - Create the Credentials for the chrome application(this would be in Installed Application section of Credentials) and web application. So that the web application can send the messages and chrome application can receive the message. Both the credentials should be part of one project.

2. Make sure the Chrome Application XMPP port is not behind the firewall.

Thank you very much
