sdk:张贴在用户的墙上
嗨,我还在学习Facebook C# SDK 5.0.3
,我正在构建一个Facebook应用程序(iFrame)。 我遵循SDK上附加的示例。 我成功运行它,我想通过创建一个按钮事件来扩展它,每次用户单击按钮时,“Hello World”都会发布到他的墙上。 这是代码;
protected void btnRegister_Click(object sender, EventArgs e)
{
try
{
var fbApp = new FacebookClient(FacebookContext.Current);
dynamic result = fbApp.Post("/me/feed", new Dictionary<string, object> { { "message", "Hello World" } });
}
catch (Exception ex)
{
Response.Write(ex.ToString());
Msg.Text = "An error may occurred while processing your request, you may try again.";
}
}
运行这段代码后,我得到这个错误
(OAuthException)(OAuthException)必须使用活动访问令牌来查询有关当前用户的信息。
请注意,在我的page_load事件中,我可以使用Sdk包中的示例成功获取用户名,
public FacebookSession CurrentSession
{
get { return (new CanvasAuthorizer()).Session; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Response.Redirect("Registration-Closed.aspx");
Panel1.Visible = true;
Panel2.Visible = false;
var auth = new CanvasAuthorizer { Perms = "user_about_me,publish_stream,offline_access" };
if (auth.Authorize())
{
ShowFacebookContent();
}
}
}
我怀疑我没有为我的按钮事件获取正确的访问令牌。
我希望我能工作:
var client = new FacebookClient("my_access_token");
dynamic parameters = new ExpandoObject();
parameters.message = "Check out this funny article";
parameters.link = "http://www.example.com/article.html";
parameters.picture = "http://www.example.com/article-thumbnail.jpg";
parameters.name = "Article Title";
parameters.caption = "Caption for the link";
parameters.description = "Longer description of the link";
parameters.actions = new {
name = "View on Zombo",
link = "http://www.zombo.com",
};
parameters.privacy = new {
value = "ALL_FRIENDS",
};
parameters.targeting = new {
countries = "US",
regions = "6,53",
locales = "6",
};
dynamic result = client.Post("me/feed", parameters);
普通访问令牌将在某些分钟后过期。我认为您的访问令牌在您致电后事件之前已过期。您可以续订您的访问令牌,然后继续
