使用 facebook c# sdk v6.0.10 执行 FQL 查询

Question

我想执行 FQL 来检索所有应用用户的朋友。

在以前版本的 sdk 中，可以使用：

var client = new FacebookWebClient();
client.Query(String.Format("SELECT uid, name FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = {0})", me.id));

但是对于 6.0.10 版本，我不知道我该怎么做。

有什么想法吗？

Answer 1

FQL

var fb = new FacebookClient("access_token");
dynamic result = fb.Get("fql", 
    new { q = "SELECT uid FROM user WHERE uid=me()" });

FQL 多查询

var fb = new FacebookClient("access_token");
dynamic result = fb.Get("fql", new
    {
        q = new[]
                {
                    "SELECT uid from user where uid=me()",
                    "SELECT name FROM user WHERE uid=me()"
                }
    });

FQL 命名多查询

var fb = new FacebookClient("access_token");
dynamic result = fb.Get("fql",
    new
        {
            q = new
            {
                id = "SELECT uid from user where uid=me()",
                name = "SELECT name FROM user WHERE uid " +
                "IN (SELECT uid FROM #id)",
            }
        });

您实际上可以通过 Graph API 调用获得相同的结果：

var client = new FacebookClient();
var query = string.Format("SELECT uid, name FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = {0})", me.id);

dynamic parameters = new ExpandoObject();
parameters.q = query;
dynamic results = client.Get("/fql", parameters);
