facebook c#sdk-用户尚未授权应用程序执行此操作 [英] facebook c# sdk - The user hasn't authorized the application to perform this action

问题描述

我正在构建一个控制台应用程序，该应用程序将流发布到页面的墙上.

I am building a console app that will publish streams to a page's wall.

问题:我收到用户未授权应用程序执行此操作".我正在使用opengraph获取访问令牌.

Issue: I'm getting "The user hasn't authorized the application to perform this action". I'm using opengraph to get the access token.

我错过了什么吗?任何帮助是极大的赞赏.谢谢！

Am I missing something? Any help is greatly appreciated. Thanks!

// constants
string apiKey = "XXX";
string secret = "XXX";
string pageId = "XXX";

// get access token
string url = string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&client_secret={1}&grant_type=client_credentials", apiKey, secret); // todo: figure out open graph url
WebRequest req = WebRequest.Create(url);
WebResponse resp = req.GetResponse();
StreamReader reader = new StreamReader(resp.GetResponseStream());
string respStr = reader.ReadToEnd();
string accessToken = respStr.Replace("access_token=", "");

// construct the post
dynamic messagePost = new ExpandoObject();
messagePost.access_token = accessToken;
messagePost.picture = "www.google.com/pic.png";
messagePost.link = "www.google.com";
messagePost.name = "some name";
messagePost.captiion = "some caption";
messagePost.description = "some description";
messagePost.req_perms = "publish_stream";
messagePost.scope = "publish_stream";

// using client
FacebookClient client = new FacebookClient(accessToken);

try // to post the post to the page's wall
{
    var result = client.Post(string.Format("/{0}/feed", pageId), messagePost); 
}
    catch (FacebookOAuthException ex)
{
    // getting caught here, with error msg = "The user hasn't authorized the application to perform this action"
}
catch (FacebookApiException ex)
{
    // ignore
}
