经过相当的搜索后，我能够在Facebook上发布自己的信息。但我的目标是张贴在我管理页面的页面上。我做了一些更多的研究，并且能够获得我管理的页面的访问令牌。当我试图职位上它，SDK给我的错误发布到Facebook页面作为页面
The user hasn't authorized the application to perform this action
这里是我供你参考代码：
string app_id = "xxxxx";
string app_secret = "yyyyyyy";
string scope = "publish_actions,manage_pages";
if (Request["code"] == null)
{
string url = string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope);
Response.Redirect(url, false);
}
else
{
Dictionary<string, string> tokens = new Dictionary<string, string>();
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&code={3}&client_secret={4}",
app_id, Request.Url.AbsoluteUri, scope, Request["code"].ToString(), app_secret);
HttpWebRequest request = System.Net.WebRequest.Create(url) as HttpWebRequest;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
string vals = reader.ReadToEnd();
foreach (string token in vals.Split('&'))
{
tokens.Add(token.Substring(0, token.IndexOf("=")),
token.Substring(token.IndexOf("=") + 1, token.Length - token.IndexOf("=") - 1));
}
}
string access_token = tokens["access_token"];
var client = new FacebookClient(access_token);
dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://www.natiska.com/article.html";
parameters.picture = "http://www.natiska.com/dav.png";
parameters.name = "Article Title";
parameters.caption = "Caption for the link";
//zzzzzzz is my fan page
string pageAccessToken = "";
JsonObject jsonResponse = client.Get("me/accounts") as JsonObject;
foreach (var account in (JsonArray)jsonResponse["data"])
{
string accountName = (string)(((JsonObject)account)["name"]);
if (accountName == MY_PAGE_NAME)
{
pageAccessToken = (string)(((JsonObject)account)["access_token"]);
break;
}
}
client = new FacebookClient(pageAccessToken);
client.Post("/zzzzzzz/feed", parameters);
