FB.getLoginStatus（）返回“未知”在用户登录时在Firefox中 [英] FB.getLoginStatus() return "unknown" in Firefox when user is logged

问题描述

在我的网站中，我测试用户是否登录Facebook，以建议他/她喜欢我的Facebook网站页面。

In my site I test if a user is logged on Facebook in order to suggest him/her to like my Facebook site page.

然后，我使用常规Facebook Js SDK功能，以了解用户是否被记录：

Then, I use the conventional Facebook Js SDK function to understand if the user is logged or not:

FB.getLoginStatus(function(response) {
    if (response.status === 'connected') {
        var accessToken = response.authResponse.accessToken;
        fbuid = response.authResponse.userID;
        status = 'connected';
    } else if (response.status === 'not_authorized') {
        fbuid = null;
        status = 'not_authorized';
    } else { // the user isn't logged in to Facebook.
        status = 'generic';
        fbuid = 1;
    }

    that.evaluateFbStatus(status, fbuid);
}

它除了Firefox以外，与每个浏览器完美匹配。

It works perfectly with every browsers except Firefox.

在Firefox中，即使t，它总是返回 unknown 他的用户登录在Facebook上，状态为 not_authorized 或已连接。

In Firefox it returns always unknown even if the user is logged on Facebook and the status is not_authorized or connected.
