Facebook API - 如何获得用户的国籍（位置）？

Question

我正在为我的手机游戏项目使用facebook phonegap插件。我的问题是我无法在通话facebookConnectPlugin后获得用户的位置。

facebookConnectPlugin.login(["email"], function(response) {
    console.log(JSON.stringify(response.authResponse.userID));
    sessionStorage.setItem("userID", JSON.stringify(response.authResponse.userID));
    facebookConnectPlugin.api(
        "me/?fields=id,email,first_name,last_name,location", ["user_birthday"],
        function(response) {
            alert(JSON.stringify(response))
        }, function(response) {
            alert(JSON.stringify(response))
        });
    $state.transitionTo('app.home');
}, function(response) {
    alert(JSON.stringify(response))
});

facebookConnectPlugin.js

        e.src = document.location.protocol + '//connect.facebook.net/en_US/sdk.js';

        document.getElementById('fb-root').appendChild(e);
    }());

}

请指教。感谢。

您不需要相应的权限user_location，如果不这样做，则无法访问数据。这很简单。
