灿任何人都会建议我为什么会收到此错误和任何可能的解

Answer 1

当您使用facebook登录进行登录时发生此错误，之后删除数据库中的用户记录。您必须在您的Facebook帐户中删除您的APP，然后重试。

Answer 2

另一个可能性是您已经登录，并且您的中间件正在尝试重新登录。在你的代码中，你没有检查用户是否已经登录，然后将请求发送到“auth/facebook”。有一种简单的方法可以证明这一点：以私人模式打开Chrome窗口，因此不使用cookie，并尝试再次你的Facebook登录好运

Answer 3

Probabily不存在的文件数据的某些属性试试！。

console.log(profile) 

为了验证文件的所有属性，在我的情况：

{ id: 'nnnnnnnn', 
    username: undefined, 
    displayName: 'My Name', 
    name: 
    { familyName: undefined, 
    givenName: undefined, 
    middleName: undefined }, 
    gender: undefined, 
    profileUrl: undefined, 
    provider: 'facebook', 
    _raw: '{"name":"My name","id":"nnnnnnnn"}', 
    _json: { name: 'My name', id: 'nnnnnnnn' } } 

不存在任何属性“电子邮件”或类似的，这会产生错误而不完整认证的cicle生活：

error: FacebookTokenError: This authorization code has been used. 

该属性的电子邮件没有得到，因为我隐藏在我的帐户Facebook的这个。

在您的代码：

... 
var data = { 
    provider: profile.provider, 
    uid: profile.id, 
    name: profile.displayName, 
    email: profile.email 
}; 
... 

行：

email: profile.email 

您已经假设属性电子邮件已经存在。

尝试：

email: (profile.emails && profile.emails[0]) ? profile.emails[0].value : ''
