我有以下代码(facebook C#SDK)发布到Facebook墙上:
public long? UploadPost(string intLinkTitle, string inMessage, string inLinkCaption, string inLinkUrl, string inLinkDescription, string inLinkUrlPicture)
{
object obj;
Facebook.JsonObject jsonObj;
FacebookClient client;
string access_token = ConfigurationManager.AppSettings["FacebookPageAccessToken"].ToString();
client = new FacebookClient(access_token);
var args = new Dictionary<string, object>();
args["message"] = inMessage;
args["caption"] = inLinkCaption;
args["description"] = inLinkDescription;
args["name"] = intLinkTitle;
args["picture"] = inLinkUrlPicture;
args["link"] = inLinkUrl;
if ((obj = client.Post("/" + ConfigurationManager.AppSettings["FacebookPageId"].ToString() + "/feed", args)) != null)
{
if ((jsonObj = obj as Facebook.JsonObject) != null)
{
if (jsonObj.Count > 0)
return long.Parse(jsonObj[0].ToString().Split('_').Last().ToString());
}
}
return null;
}
}
只要我发布到我的公共Facebook网站页面,但是当将FacebookPageId
更改为组ID而不是(FacebookApiException - #200) Permissions error
时,这会很有效。
我的用户是群组和网页的管理员。
我尝试使用以下行从图谱API资源管理器发布消息:294632750660619/feed/?message=test
但是这里存在语法问题,也尝试了294632750660619/feed?message=test
但没有成功。
如何发布到已关闭的Facebook群组?
答案 0 :(得分:0)
好的,我找到了正确的方法。这就是我要做的事情:
user_groups
,user_status
,user_photos
,manage_pages
,publish_actions
,read_insights
和read_stream
)和单击“获取访问令牌”。现在我们做了一个短暂的生活https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=[app-id]&client_secret=[app-secret]&fb_exchange_token=[short-lived-token]
https://developers.facebook.com/tools/debug/access_token/
使用此代码上传帖子:
public long? UploadPost(string intLinkTitle, string inMessage, string inLinkCaption, string inLinkUrl, string inLinkDescription, string inLinkUrlPicture)
{
object obj;
Facebook.JsonObject jsonObj;
FacebookClient client;
string access_token = ConfigurationManager.AppSettings["FacebookPageAccessToken"].ToString();
client = new FacebookClient(access_token);
var args = new Dictionary<string, object>();
args["message"] = inMessage;
args["caption"] = inLinkCaption;
args["description"] = inLinkDescription;
args["name"] = intLinkTitle;
args["picture"] = inLinkUrlPicture;
args["link"] = inLinkUrl;
if ((obj = client.Post("/" + ConfigurationManager.AppSettings["FacebookPageId"].ToString() + "/feed", args)) != null)
{
if ((jsonObj = obj as Facebook.JsonObject) != null)
{
if (jsonObj.Count > 0)
return long.Parse(jsonObj[0].ToString().Split('_').Last().ToString());
}
}
return null;
}
要获得Feed,请使用:
private void GetFeed()
{
object obj;
Facebook.JsonObject jsonObj;
Facebook.JsonObject jsonPaging;
FacebookClient client;
int pageCount = 0;
string access_token;
string URL;
DateTime fetchFaceBookFeedFromDate;
DateTime? oldestPostFetched = null;
fetchFaceBookFeedFromDate = DateTime.Now.AddDays(-30);
access_token = ConfigurationManager.AppSettings["FacebookPageAccessToken"].ToString();
URL = "/" + ConfigurationManager.AppSettings["FacebookPageId"].ToString() + "/feed";
client = new FacebookClient(access_token);
while (URL.Length > 0 && pageCount < 1000)
{
if ((obj = client.Get(URL)) != null)
{
if ((jsonObj = obj as Facebook.JsonObject) != null && jsonObj.Count > 0)
{
if (jsonObj[0] is Facebook.JsonArray)
oldestPostFetched = SaveFacebookForumThread(jsonObj[0] as Facebook.JsonArray, fetchFaceBookFeedFromDate);
if (jsonObj.Keys.Contains("paging") && (jsonPaging = jsonObj["paging"] as Facebook.JsonObject) != null && jsonPaging.Keys.Contains("next"))
URL = jsonPaging["next"].ToString();
else
break;
}
}
pageCount++;
if (oldestPostFetched.HasValue && fetchFaceBookFeedFromDate > oldestPostFetched)
break;
}
}
