OAuth - Login With Moodle

Question

I am building a chrome extension for a school, and it needs to authenticate with moodle, meaning that I need a OAuth or OpenID like setup, I open a page to moodle, the user then logs in/approves the app, and then a token is returned, which I can then use for normal moodle web service calls. Is this possible?

Thanks, Ari

I has a similar issue when trying to authenticate an extension using oauth, the flow I used was first check if we have tokens stored: if not then open a new tab from a background page, which means it will be ran when the extension is first installed, although if the token is there we go on to run our requests, but I asked the user to close the tab after the approval has been completed, which I set a listener for after it was created, then I knew that the process was complete and I could make requests.

If you need any code for sections of this, I'd be happy to post.

Good Luck

Update:

check if we have tokens saved :

if(localStorage.token){
    if(localStorage.secret){

if not :

else{
    var authURL = bgOauth.requestTokenCall();
    var req = new XMLHttpRequest();
    req.overrideMimeType("application/json");
    req.onload = bgOauth.processRequestTokenData;
    req.open("get", authURL, true);
    req.send();
    console.log('sent')
}

then I process the response from this, if all good then I open a new tab:

startPopup : function(destinationurl) {

    chrome.tabs.create({url : destinationurl}, 
    function(tab){bgOauth.newTabId = tab.id})
    alert(Instructions)     
    chrome.tabs.onRemoved.addListener(function(tabId)
    {
        console.log('oh no, closed');
        if(tabId == bgOauth.newTabId){
            console.log('freaking sweet!');
            bgOauth.handleApproval()
        }   
        else{
            return false;
        }
    })

Then I can finish the authorization process, and preform requests be sure to save your credentials in localStorage.
