我正在使用这个 facebook sdk -https://github.com/facebook/facebook-android-sdk/

这是我在墙上发布消息的代码：

 private static void postOnWall(String msg) {
            Log.d(LOGTAG, "Testing graph API wall post");
             try {
                 //   String response = facebook.request("me");
                    Bundle parameters = new Bundle();
                    parameters.putString("message", msg);
                    parameters.putString("description", "test test test");
                    String response = facebook.request("me/feed", parameters, 
                            "POST");
                    Log.d(LOGTAG, "got response: " + response);
                    if (response == null || response.equals("") || 
                            response.equals("false")) {
                       Log.v(LOGTAG, " error Blank response");
                    }
             } catch(Exception e) {
                 e.printStackTrace();
             }
        }

Answer 1

您会收到此异常的三个原因：

1. 您尚未在清单中声明互联网权限
2. 该设备没有互联网连接，或者有一个在 DNS 级别阻止 facebook 访问的设备。如果您使用公司代理，请尝试使用家庭网络。
3. Facebook 的服务器暂时无法工作。

Answer 2

我明白了

得到响应：{"error":{"message":"必须使用活动访问令牌来查询有关当前用户的信息。","type":"OAuthException","code":2500}}
