我们正在使用restfb 1.6.14。我在获取公共帖子时收到以下错误。

com.restfb.exception.FacebookOAuthException: Received Facebook error response of

使用以下代码获取访问令牌

AccessToken accessToken = new
    DefaultFacebookClient().obtainAppAccessToken(appid,appsecret);
    String token=accessToken.getAccessToken();

使用以下源代码获取公开信息

public Connection<Post> publicSearchMessages(String keyword, int limit) {
    Connection<Post> messages = fbClient.fetchConnection("search",
            Post.class, Parameter.with("q", keyword),
            Parameter.with("limit", limit), Parameter.with("type", "post"));

    return messages;
}

为什么会出现此错误?我该如何解决这个错误?

使用Graph API 2.0,您不能搜索帖子,甚至是公开的帖子。
