春季社交Facebook错误

标签： spring spring-social spring-social-facebook

我正在使用Spring Social Facebook插件;我有一个非常简单的场景：我想在我的网页上显示我的用户帐户Feed;到目前为止，我已经构建了一个非常简单的JUnit测试，以便列出我的FB墙帖，但我面临一些Spring社交集成的问题 我正在使用spring 4.0.5和spring social 1.1.0

从我在文档中看到的，我不需要使用spring社交连接框架（也许我将来会使用ConnectionRepository，以便不会在每个请求上总是进行FB和/或twitter连接，但现在我不需要处理几个用户）

因此，在我在FB上创建测试APP并获得appClientID和appClientSecret之后，我编写了这个简单的XML配置：

                </bean>
            </list>
        </property>
    </bean>
</beans>

我写了这个简单的java类（我在代理后面，但我可以到达FB ......我的网络管理员授予我到FB）：

相反，如果我在FB上生成APP令牌并直接在FacebookTemplate中使用它，那么一切都很好。 我该如何解决这个问题？我错了什么？任何提示真的很感激

谢谢 安吉洛

答案 0 :(得分：0)

我立即看到了一些错误。您遇到的主要问题是网络问题 - 而不是代码问题或Spring Social问题。即使您的网络管理员说您可以看到Facebook，您展示的例外情况也会告诉我。这是你需要解决的问题。

一旦你越过那个，我怀疑这无论如何都会有用。您可以通过authenticateClient（）获取访问令牌，该令牌仅授予您客户端令牌。但是，您尝试将其用于特定于用户的请求，例如获取主页Feed。您必须拥有用户令牌才能执行该操作，并且您只能通过用户授权获得用户令牌，即＃34; OAuth Dance＆＃34;。 Spring Social的ConnectController可以为您提供帮助。
