如何使用C#没有游客发表于Facebook页面直接张贴? [英] how to post on directly at facebook page using C# not at visitor post?
问题描述
我审阅这篇文章
如何张贴到Facebook页面墙从.NET 但它的Facebook页面上的工作后为游客职。
我想不是游客发表后页时间表的,我这个页面和应用程序的管理。
请给它的解决方案。
在这里我的code
使用系统;
使用System.Collections.Generic;
使用System.IO;
使用System.Linq的;
使用System.Net;
使用的System.Web;
使用System.Web.UI程序;
使用System.Web.UI.WebControls;
使用Facebook的;
使用System.Dynamic;公共部分类Facebook的:System.Web.UI.Page
{
保护无效的Page_Load(对象发件人,EventArgs的发送)
{
authontication();
}
私人无效authontication()
{
字符串APP_ID =************
字符串app_secret =###################################;
字符串范围=publish_actions,manage_pages 如果(请求[code] == NULL)
{
的Response.Redirect(的String.format(
https://graph.facebook.com/oauth/authorize?client_id={0}&redirect_uri={1}&scope={2},
APP_ID,Request.Url.AbsoluteUri,范围));
}
其他
{
字典<字符串,字符串>令牌=新词典<字符串,字符串>(); 字符串的URL = string.Format(\"https://graph.facebook.com/oauth/access_token?client_id={0}&redirect_uri={1}&scope={2}&$c$c={3}&client_secret={4}\",
APP_ID,Request.Url.AbsoluteUri,范围,请求[code]的ToString(),app_secret)。 HttpWebRequest的要求= System.Net.WebRequest.Create(URL)为HttpWebRequest的; 使用(HttpWebResponse响应= request.GetResponse()作为HttpWebResponse)
{
StreamReader的读者=新的StreamReader(response.GetResponseStream());
字符串瓦尔斯= reader.ReadToEnd(); 的foreach(字符串令牌vals.Split('和;'))
{
//meh.aspx?token1=steve&token2=jake& ...
tokens.Add(token.Substring(0,token.IndexOf(=)),
token.Substring(token.IndexOf(=)+ 1,token.Length - token.IndexOf(=) - 1));
}
}
字符串的access_token =令牌[的access_token];
VAR的客户=新FacebookClient(的access_token); //动态参数=新ExpandoObject();
字符串名称=sudhanshu; 名称+ =新数据; client.Post(/ 1168908853153698 /饲料,新{消息=我的第一appProduct+名字+。}); } }}
您需要使用页面令牌,而不是一个用户令牌。确保它确实是一个页面令牌通过调试它: https://developers.facebook.com/工具/调试/的accessToken /
此外, publish_actions
是张贴的页面错误的权限,则需要使用 publish_pages
。

You need to use a Page Token, not a User Token. Make sure it really is a Page Token by debugging it: https://developers.facebook.com/tools/debug/accesstoken/
Also, publish_actions
is the wrong permission to post as Page, you need to use publish_pages
.
