我已经下载了C#的Facebook SDK简单MVC网站示例从CodePlex上的:
I've downloaded the C# Facebook SDK "Simple MVC Website Example" from CodePlex at:
的
和已经成功地得到它来验证我的测试Facebook应用程序。但我不是很制定出如何获得访问令牌(我会想离线访问,所以我只需要抓住该令牌一次,当用户第一次授权我的应用程序来抓住他们的饲料数据)。
and have successfully got it to authenticate to my test Facebook app. But I can't quite work out how to get the access token (and I'm going to want offline access, so I only need to grab that token once, when the user first authorizes my app to grab their feed data).
非常感谢
推荐答案
您会希望做两件事情。首先,要求offline_access,您需要更改的JavaScript登录功能要求离线访问如下。这是在查看/主页/的Index.aspx
You will want to do two things. First, to request offline_access, you need to change the Javascript login function to request offline access as follows. This is in the Views/Home/Index.aspx.
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({ appId: '<%:FacebookSettings.Current.AppId %>', status: true, cookie: true, xfbml: true });
$('#fbLogin').click(function() {
FB.login(function (response) {
if (response.session) {
window.location = '<%:Url.Action("Profile") %>'
} else {
// user cancelled login
}
}, { perms: 'offline_access' });
});
</script>
</asp:Content>
接下来,以获得访问令牌,你只是做在行动以下用户通过验证后:
Next, to get the access token, you just do the following in action after the user is authenticated:
public ActionResult Profile()
{
var app = new FacebookApp();
if (app.Session == null)
{
// The user isnt logged in to Facebook
// send them to the home page
return RedirectToAction("Index");
}
// Read current access token:
var accessToken = app.Session.AccessToken;
// Get the user info from the Graph API
dynamic me = app.Api("/me");
ViewData["FirstName"] = me.first_name;
ViewData["LastName"] = me.last_name;
return View();
}
