使用c sharp将短期用户访问令牌转换为长期用户访问令牌

Question

我在下面的代码中获得了短期用户访问令牌。

请亲切指导我应该如何转换并获得长期用户访问令牌。

var fb = new FacebookClient(); 
dynamic result = fb.Get("oauth/access_token", new 
{ 
    client_id = "done", 
    client_secret = "done", 
    grant_type = "client_credentials" 
}); 

fb.AccessToken = result.access_token; 
Label1.Text = fb.AccessToken;

服务器端webservice1.acmx

[WebMethod] 
    public string getlonToken(string accessToken) 
    { 
     var fb = new FacebookClient(accessToken); 
     dynamic result = fb.Get("oauth/access_token", new 
      { 
       client_id = yourid, 
       client_secret = "yoursec", 
       grant_type = "fb_exchange_token", 
       fb_exchange_token = accessToken, 
       scope = "user_about_me,friends_about_me,user_activities,friends_activities,user_birthday,friends_birthday,user_checkins,friends_checkins,user_education_history,friends_education_history,user_events,friends_events,user_groups,friends_groups,user_hometown,friends_hometown,user_interests,friends_interests,user_likes,friends_likes,user_location,friends_location,user_notes,friends_notes,user_photos,friends_photos,user_relationships,friends_relationships,user_relationship_details,friends_relationship_details,user_religion_politics,friends_religion_politics,user_status,friends_status,user_videos,friends_videos,user_website,friends_website,email,manage_pages,publish_stream,read_stream,read_page_mailboxes,read_insights,ads_management" 
      }); 

     fb.AccessToken = (string)result["access_token"]; 
     return fb.AccessToken; 
    } 

客户端。

function statusChangeCallback(response) { 
     console.log('statusChangeCallback'); 
     console.log(response); 

     if (response.status === 'connected') { 

      { 
       event.preventDefault(); 
       FB.login(function (response) { 
        if (response.authResponse) { 
         var profileId = response.authResponse.userID; 
         var accessToken = response.authResponse.accessToken; 
         var e = response.authResponse.accessToken; 
         document.getElementById('token').innerHTML = e; 
         var profileName = ""; 
         var pagesList = ""; 
         var isPage = 0; 
         var type = "fb"; 

         $.ajax({ 
          url: "WebService1.asmx/getlonToken", 
          type: "POST", 
          dataType: 'json', 
          data: '{accessToken:"' + accessToken + '"}', 
          contentType: "application/json; charset=utf-8", 
          async: true, 
          success: function (response) { 
           accessToken = response.d; 
           document.getElementById('status').innerHTML = accessToken; 
          }, 
          error: function (e) { 
           alert('Error' + e); 
          } 
         }); 

        } 
       }, { scope: 'user_about_me,friends_about_me,user_activities,friends_activities,user_birthday,friends_birthday,user_education_history,friends_education_history,user_events,friends_events,user_groups,friends_groups,user_hometown,friends_hometown,user_interests,friends_interests,user_likes,friends_likes,user_location,friends_location,user_notes,friends_notes,user_photos,friends_photos,user_relationships,friends_relationships,user_relationship_details,friends_relationship_details,user_status,friends_status,user_videos,friends_videos,user_website,friends_website,email,manage_pages,publish_stream,read_stream,read_page_mailboxes,read_insights, read_mailbox' }); 

      } 
     } 
     else if (response.status === 'not_authorized') { 
      document.getElementById('status').innerHTML = 'Please log ' + 
       'into this app.'; 
     } else { 

      document.getElementById('status').innerHTML = 'Please log ' + 
     'into Facebook.'; 
     } 
    } 

    FB.getLoginStatus(function (response) { 

      statusChangeCallback(response); 
     });

这就是我这样做，我不说这是最好的，但它工作正常。

public void FacebookShortToLongToken(string shortToken) 
     { 
      FacebookClient User = new FacebookClient(shortToken); 
      string url = "https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=" 
        + {Your app id} 
        + "&client_secret=" + {Your app secret id} 
        + "&fb_exchange_token=" + shortToken;     
      JObject LongTokenResponse = JObject.Parse(User.Get(url).ToString()); 
      string LongLiveToken = LongTokenResponse["access_token"].ToString(); 
     }
