Facebook代币交换代码

当您成功地将“代码”交换为令牌时

facebook的以下回复（html正文）

但是当这个令牌交换代码失败时会发生什么呢？当交换失败时，facebook如何反应

---

Reference

只要请求中的一个参数不正确，facebook就可能无法向应用程序返回访问令牌。在开发oauth框架的过程中，我测试了将每个必需的参数设置为不正确的值（即我在正确值的开头追加了字符串

123abc

）。结果如下：

从facebook请求访问令牌时客户端id错误，返回json错误：

当然，如果我没有将

123abc

附加到值中，那么在每种情况下都会正确返回访问令牌

这些响应截止到2012年12月，但facebook当然可能会在未来的任何时候决定在没有任何警告的情况下更改它们。

据我所知，SDK都会抛出一个异常（在PHP中是OauthException）——当您尝试使用无效代码时会发生什么？您的SDK是否将其包装为异常？“验证客户端机密时出错”我也会遇到“当我的应用程序id不正确时”的错误。
