下面是获取访问令牌的方法,它确实返回有效的访问令牌

        string accessToken = GetAccessToken();
        string accessKey = accessToken.Split('=')[1];

        var client = new FacebookClient(accessKey);
        dynamic me = client.Get("me");
但是,当我调试结束时

private static string GetAccessToken()
    {
        // Create a request using a URL that can receive a post. 
        WebRequest request = WebRequest.Create("https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=201193246663533&client_secret=secretkeyhere");
        // Set the Method property of the request to POST.
        request.Method = "POST";
        // Create POST data and convert it to a byte array.
        string postData = "This is a test that posts this string to a Web server.";
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        // Set the ContentType property of the WebRequest.
        request.ContentType = "application/x-www-form-urlencoded";
        // Set the ContentLength property of the WebRequest.
        request.ContentLength = byteArray.Length;
        // Get the request stream.
        Stream dataStream = request.GetRequestStream();
        // Write the data to the request stream.
        dataStream.Write(byteArray, 0, byteArray.Length);
        // Close the Stream object.
        dataStream.Close();
        // Get the response.
        WebResponse response = request.GetResponse();
        // Display the status.
        Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        // Get the stream containing content returned by the server.
        dataStream = response.GetResponseStream();
        // Open the stream using a StreamReader for easy access.
        StreamReader reader = new StreamReader(dataStream);
        // Read the content.
        string responseFromServer = reader.ReadToEnd();
        // Display the content.
        Console.WriteLine(responseFromServer);
        // Clean up the streams.
        reader.Close();
        dataStream.Close();
        response.Close();

        return responseFromServer;
    }

如何解决此问题?

您正在为应用程序而不是用户获取访问令牌。因此,“我”没有意义。您应该在此处提供ID-您的用户ID、应用程序ID或应用程序具有权限的任何其他ID

这两个调用都适用于您的示例:

dynamic me = client.Get("me");
dynamic me=client.Get(“10005735”);
动态theApp=client.Get(“20119324663533”);

谢谢您的回答,但是如何获得每个请求的用户。我对我的信息不感兴趣,我想要用户的信息。因此,如果你看:,它说我需要用“我”,我想你是糊涂了。如果不显示FB身份验证对话框,则无法获取用户的访问令牌。您从代码中得到的是应用程序令牌,例如,您可以使用它来获取洞察数据,或创建测试用户,等等。如果您想对用户进行身份验证,那么您应该使用服务器端流或Javascript SDK。检查:-这可以帮助您了解用于身份验证的服务器端流。这是服务器端身份验证的官方页面:@avs099我们可以不使用对话框获得好友信息和帖子吗。如果遵循您提供的服务器端流链接,但现在看起来很旧,您可以在那里查看我的评论
dynamic me = client.Get("1000<<MY_USER_ID>>5735");

dynamic theApp = client.Get("201193246663533");
