使用spring-social-facebook在java中执行简单的FQL查询

Question

对于春季社交facebook图书馆的实现，我会非常感激。我正在尝试执行FQL查询，但是facebook给我发送了空的结果。如果我在中执行相同的查询，它的工作原理就像一个魅力。我检查了所有权限。我的代码是这样的：

private static final String FQL_GET_FRIENDS = "SELECT uid, name FROM user WHERE uid IN(SELECT uid2 FROM friend WHERE uid1 = me())";

Facebook facebook = new FacebookTemplate(token);
List<Reference> references = facebook.userOperations().search(FQL_GET_FRIENDS);

谢谢你的建议

Answer 1

好的。这对我起了作用：

MultiValueMap<String, String> parameters = new LinkedMultiValueMap<String, String>();
        parameters.set("q", FQL_GET_FRIENDS);
Map<String, Object> resultSet = (Map<String, Object>) facebookTemplate
                .fetchObject("fql", Map.class, parameters);

Answer 2

我通过简单的HTTP请求使用具有足够权限的有效令牌对"faceBookURL“进行了同样的操作，您可以使用以下命令：

private static String STR_FACEBOOK_FQL_URL = "https://api.facebook.com/method/fql.query?query=";
private static String STR_FACEBOOK_RETURN_FORMAT = "&format=json";
private static String STR_FACEBOOK_ENCODE_FORMAT = "UTF-8";
private static String STR_FACEBOOK_ACCESS_TOKEN = "&access_token=";

private static final String FQL_GET_FRIENDS = "SELECT uid, name FROM user WHERE uid IN(SELECT uid2 FROM friend WHERE uid1 = me())";

String encodedQuery = URLEncoder.encode(FQL_GET_FRIENDS, STR_FACEBOOK_ENCODE_FORMAT);
String faceBookURL = STR_FACEBOOK_FQL_URL + encodedQuery + STR_FACEBOOK_RETURN_FORMAT
        + STR_FACEBOOK_ACCESS_TOKEN + token;
