Comment utiliser L'API de connexion Google avec Cordova / Phonegap

Ajoutez ce code dans un fichier js et incluez - le dans votre projet. lorsque vous souhaitez accéder à l'api de connexion google sur le bouton, cliquez sur l'appel function callGoogle() rest sera effectué par ce code. N'oubliez pas d'ajouter vos clés client id et Client_Secret. Sa fonctionne très bien pour moi. Vous avez besoin InAppBrowser cordova plugin.

var googleapi = {
    authorize: function(options) {
        var deferred = $.Deferred();
         //Build the OAuth consent page URL
        var authUrl = 'https://accounts.google.com/o/oauth2/auth?' + $.param({
            client_id: options.client_id,
            redirect_uri: options.redirect_uri,
            response_type: 'code',
            scope: options.scope
        });

        //Open the OAuth consent page in the InAppBrowser
        var authWindow = window.open(authUrl, '_blank', 'location=no,toolbar=no');

        //The recommendation is to use the redirect_uri "urn:ietf:wg:oauth:2.0:oob"
        //which sets the authorization code in the browser's title. However, we can't
        //access the title of the InAppBrowser.
        //
        //Instead, we pass a bogus redirect_uri of "http://localhost", which means the
        //authorization code will get set in the url. We can access the url in the
        //loadstart and loadstop events. So if we bind the loadstart event, we can
        //find the authorization code and close the InAppBrowser after the user
        //has granted us access to their data.
        $(authWindow).on('loadstart', function(e) {
            var url = e.originalEvent.url;
            var code = /\?code=(.+)$/.exec(url);
            var error = /\?error=(.+)$/.exec(url);

            if (code || error) {
                //Always close the browser when match is found
                authWindow.close();
            }

            if (code) {
                //Exchange the authorization code for an access token
                $.post('https://accounts.google.com/o/oauth2/token', {
