在此处输入代码我一直在关注C#的Facebook教程并获取访问令牌,我刚刚得到了它,但似乎无法理解其教程中关于事件处理和重定向。我从来没有做过类似的JavaScript使用C#。我有以下几点:Facebook登录后重定向C#
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '{app Id}', // App ID
status: true, // check login status
cookie: true, // enable cookies to allow the server to access the session
xfbml: true // parse XFBML
});
// Additional initialization code here
FB.Event.subscribe('auth.authResponseChange', function (response) {
if (response.status === 'connected') {
// the user is logged in and has authenticated your
// app, and response.authResponse supplies
// the user's ID, a valid access token, a signed
// request, and the time the access token
// and signed request each expire
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
// TODO: Handle the access token
// Do a post to the server to finish the logon
// This is a form post since we don't want to use AJAX
var form = document.createElement("form");
form.setAttribute("method", 'post');
form.setAttribute("action", '/FacebookLogin.ashx');
var field = document.createElement("input");
field.setAttribute("type", "hidden");
field.setAttribute("name", 'accessToken');
field.setAttribute("value", accessToken);
form.appendChild(field);
document.body.appendChild(form);
form.submit();
} else if (response.status === 'not_authorized') {
// the user is logged in to Facebook,
// but has not authenticated your app
} else {
// the user isn't logged in to Facebook.
}
});
};
// Load the SDK Asynchronously
(function (d) {
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) { return; }
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
除了作为一个Facebook的按钮,一切正常找到,但随后,根据教程Here我需要“接下来,创建一个页面,操作或处理接收的令牌和重定向在这个例子中,我们将创建一个通用处理程序。“
他们用这样的:
public class FacebookLogin : IHttpHandler, System.Web.SessionState.IRequiresSessionState {
public void ProcessRequest(HttpContext context) {
var accessToken = context.Request["accessToken"];
context.Session["AccessToken"] = accessToken;
context.Response.Redirect("/MyUrlHere");
}
public bool IsReusable {
get { return false; }
}
}
我只是把在我后面的代码,但它没有做任何事情。我只是不确定要从这里做什么。如何让我的网页重定向到一个新的页面,所以我可以做这样的事情:
var accessToken = Session["AccessToken"].ToString();
var client = new FacebookClient(accessToken);
dynamic result = client.Get("me", new { fields = "name,id" });
string name = result.name;
string id = result.id;
做了一些测试,它看起来像FB.Event.subscribe后(“auth.authResponseChange”,函数(响应)从来没有得到调用。我错过了什么? – KJ3 2013-02-23 22:14:21
你是否得到这个工作即时通讯工作现在,但像你自己不知道如何登录用户回来,当他们修改网站 – rogue39nin 2015-12-14 14:14:04
