FacebookConnectionFactory 连接“https://graph.facebook.com/me”的 GET 请求导致 400（错误请求）MissingAuthorizationException：

Question

我正在尝试为 Facebook 开发一个应用程序。我编写了一个 facebook 控制器并创建了 connectionFactory 对象，获取了 oAuth 操作和 accessgrant 对象。我也获得了访问令牌，但是一旦我尝试创建连接，

Connection<Facebook> connection = connectionFactory.createConnection(accessGrant);

我就会收到错误：

MissingAuthorizationException：操作需要授权，但 API 绑定是在未经授权的情况下创建的。

            }

        } catch (IOException e) {
            e.printStackTrace();
        }

       return null;  
    }
}

请让我知道这里出了什么问题？ ConnectionFactory 对象的实例化不正确。

您需要将Connection添加到usersConnectionRepository，因为社交尝试找到用户已建立的连接（如果有），并尝试对其进行授权并使用它
