从今天早上（现在超过 8 小时）开始，我一直在尝试解决一个问题。我得到了 facebook cookie 内容，找到了在浏览器中可以正常工作的身份验证令牌
但
每当我尝试获取用户信息时，网页都会很好地崩溃并出现以下错误。
我尝试使用网络请求从页面中读取：
'Dim inputFile As String = "https://graph.facebook.com/me?access_token=" & access_token
'Dim sDiskFile As String = "auth.txt"
'Dim _wrequest As WebRequest = WebRequest.Create(inputFile)
'Dim _wresponse As WebResponse
'_wresponse = _wrequest.GetResponse()
'Dim _stream As Stream = _wresponse.GetResponseStream()
'Dim oReader As New StreamReader(_stream, Encoding.ASCII)
它因同样的错误而崩溃。我决定试一试 Facebook SDK 5，但同样的错误发生了：
Dim access_token As String = GetFacebookTokenFromCookie()
If access_token = "" Then
litUser.Text = "<fb:login-button perms='email'>Login with Facebook</fb:login-button>"
Else
Dim app As New DefaultFBApp
Dim _ctx As New FacebookWebContext(app)
Dim fb As New Facebook.FacebookClient(app)
fb.AccessToken = access_token
Dim parameters As New Dictionary(Of String, Object)()
parameters("fields") = "id,name"
Dim result As Object = fb.Get(parameters)
Dim id = result.id
Dim name = result.name
Dim firstName As String = result.first_name
Dim lastName = result.last_name
Dim link = result.link
Dim username = result.username
Dim gender = result.gender
Dim male = result.locale
litUser.Text = "Welcome " & firstName
End If
DefaultFBApp is:
Public Class DefaultFBApp
Implements Facebook.IFacebookApplication
添加了所有必须实现的字段并填写了 api 密钥和秘密。
同样的错误：
