您会注意到,在我的示例中,我同时要求publish_stream"和manage_pages".这让您还可以在用户是管理员的页面上发帖.完整代码如下:
You will notice that, in my example, I am asking for both "publish_stream" and "manage_pages". This let's you also post on pages of which that users is an admin. Here is the full code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Facebook;
namespace FBO
{
public partial class facebooksync : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
CheckAuthorization();
}
private void CheckAuthorization()
{
string app_id = "374961455917802";
string app_secret = "9153b340ee604f7917fd57c7ab08b3fa";
string scope = "publish_stream,manage_pages";
if (Request["code"] == null)
{
Response.Redirect(string.Format(
"https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2}",
app_id, Request.Url.AbsoluteUri, scope));
}
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 = 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('&'))
{
//meh.aspx?token1=steve&token2=jake&...
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);
client.Post("/me/feed", new { message = "markhagan.me video tutorial" });
}
}
}
}
