应用程序访问令牌早些时候工作,但在重大更改之后,应用程序停止工作。我得到的错误是
(#200) Must have a valid access_token to access this endpoint
我已将以下代码用于访问令牌
var fb = new FacebookClient();
dynamic result = fb.Get("oauth/access_token", new {
client_id = XXXX,
client_secret = XXXXX,
grant_type = "client_credentials",
scope = "publish_stream"
});
我该如何解决这个问题?
