Question

I started with an little application for showing some relevant information to our developer team, which is collected from different sources. Like google calendar, our project backoffice, an openarena server-logs etc.

I started with an web application, but then decided to switch the project to an chrome extension. Now i already had the google calendar integration up and running using the V3 Javascript(alpha) Client-Lib. This wasn’t working anymore because i had to change the OAUTH dance, from the one for web-apps, to the one for packaged/installed apps.

For this i followed the tutorial (It’s my first extension.) http://code.google.com/chrome/extensions/tut_oauth.html and got the OAUTH dance working again. Now i’am trying to request my calendar-data from the google api using the signedRequest-Methode from the tutorial, but alway receive the response “Daily Limit Exceeded. Please sign up” (Api Console shows i haven’t performed any request).

Maybe someone has an idea what i am doing wrong here, because i tried everthing i could think about. Thanks in advance, Florian

Code –
manifest.json:

{
    "name": "MIS",
    "version": "0.1",
    "description": "Monitor Information System",
    "background_page": "background.html",

    "browser_action": {
        "default_icon": "img/mis/icon.png",
        "default_title": "Mis"
    },

    "permissions": [
    "tabs",
    "https://www.googleapis.com/",
    "https://www.google.com/"]
}

background.html:

...         
oauth = ChromeExOAuth.initBackgroundPage
({
'request_url':'https://www.google.com/accounts/OAuthGetRequestToken',
'authorize_url':'https://www.google.com/accounts/OAuthAuthorizeToken',

'consumer_key': 'anonymous',
'consumer_secret': 'anonymous',
'scope': 'https://www.googleapis.com/auth/calendar',
'app_name': 'Mis'
}); 
...

main.html Methode call:

function performCalendarEventsRequest(calendarId)
{
var requestUrl = 'https://www.googleapis.com/calendar/v3/calendars/'+calendarId+'/events';
var request = {
    'method': 'GET',
    'headers': {
      'GData-Version': '3.0',
      'Content-Type': 'application/atom+xml'
    },
    'parameters': {
      'alt': 'json'
    },
    'body': 'Data to send'
  };

 oauth.sendSignedRequest(requestUrl, calendarEventsRequestCallback, request);
}

Answer 1

Since your consumer key and secret are both set as anonymous you are not identifying your application in any way.

You can either replace these with the Client ID and Client secret values respectively, which can be found on the API Access tab on your projects page in the API Console, or you can pass the API key (found just under the auth tokens on the same page) using an additional key parameter.

This is the same for most Google APIs.
