string accessToken = GetAccessToken();
string accessKey = accessToken.Split('=')[1];
var client = new FacebookClient(accessKey);
dynamic me = client.Get("me");
这是获取访问令牌的方法,它确实返回了一个有效的访问令牌
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;
}
然而,当我调试
时dynamic me = client.Get("me");
抛出此异常:
(OAuthException - #2500)必须使用活动访问令牌来查询有关当前用户的信息。
我该如何解决这个问题?
答案 0 :(得分:6)
您正在获取APPLICATION的访问令牌,而不是用户。因此,“我”没有意义。您应该在那里提供ID - 您的用户ID,或您的应用ID,或您的应用有权使用的任何其他ID。
这两个电话都适用于你的例子:
dynamic me = client.Get("1000<<MY_USER_ID>>5735");
dynamic theApp = client.Get("201193246663533");
