调用FB.logout()而不使用访问令牌. JavaScript SDK [英] FB.logout() called without an access token. javascript sdk

问题描述

对此完全迷失，并且文档并没有真正给与任何对此的见识...

Totally lost on this and docs don't really give any insight on this...

在我的应用程序中使用Facebook Javascript SDK，并使用以下登录按钮代码:

Using the Facebook Javascript SDK in my app with this login button code:

<fb:login-button scope="manage_pages,read_insights,ads_management" autologoutlink="true" size="large"></fb:login-button>

根据文档，autologoutlink=true参数会在用户登录后将login按钮变为log out.我想保留此功能，而不要编写自己的按钮代码

As per the docs, autologoutlink=true param turns the login button to log out once the user is logged in. I want to keep this functionality and not write my own button code

此事件调用FB.logout，但仍在回调中返回错误消息

This event calls FB.logout but still returns the error message in the callback

FB.Event.subscribe('auth.logout', function(response) {                                              
    FB.logout(function(response) {
        // FB.logout() called without an access token.
    });
});

我想使用Facebook Login Widget，而不是我自己的按钮进行登录，因此关于同一主题的其他答案无济于事.我不明白我应该如何通过access_token来证明我有权注销...

I would like to use the Facebook Login Widget and not my own button for login, so the other answers on the same subject don't help. I don't understand how I'm supposed to pass the access_token to prove I'm authorized to logout...

推荐答案

显然，这是不可能的，至少我无法确定.快速解决方案是从自定义Log Out按钮调用此函数:

Apparently this isn't possible, at least in no way I can figure out. Quick solution is call this function from a custom Log Out button:

function fbLogoutUser() {
    FB.getLoginStatus(function(response) {
        if (response && response.status === 'connected') {
            FB.logout(function(response) {
                document.location.reload();
            });
        }
    });
}

页面重新加载向Facebook发出另一个请求，然后Facebook看到未授权状态并从浏览器中删除cookie，这反过来又使access_token无效.因此，这会将用户从网站和Facebook中注销.

The page reload makes another request to Facebook which then sees the unauthorized state and removes the cookie from the browser which in turn invalidates the access_token. So this logs out the user from the site and from Facebook.
