Spring social facebook 无法解码从 facebook 访问令牌 URI 发送的信息

Question

代码在一周前按预期工作，用于解释访问令牌。现在突然开始抛出异常：

org.springframework.social.MissingAuthorizationException: Authorization is required for the operation, but the API binding was created without authorization.

我尝试调试库中的代码，发现返回的响应不是需要由spring-social-facebook-1.1.1.RELEASE-sources.jar-> FacebookOAuth2Template-> postForAccessGrant() 解释的所需格式。在下面的代码 sn-p 中，access_token 和 expires 需要使用键值。

@Override
    @SuppressWarnings("unchecked")  
    protected AccessGrant postForAccessGrant(String accessTokenUrl, MultiValueMap<String, String> parameters) {
        MultiValueMap<String, String> response = getRestTemplate().postForObject(accessTokenUrl, parameters, MultiValueMap.class);
        String expires = response.getFirst("expires");
        return new AccessGrant(response.getFirst("access_token"), null, null, expires != null ? Long.valueOf(expires) : null);
    }

facebook graph access token API 返回的响应是：

{{"access_token":"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX","token_type":"bearer","expires_in":5157689}=[null]}

response.get 行试图从值字段中检索这些值，在本例中为 null。因此它将accessToken 和expiry 值设置为null。

我添加了下面的类作为项目的临时修复，它覆盖了库中的现有类，但这不是一个合适的解决方案。有什么办法可以解决这个问题吗？
