FB连接：（417）预期失败 [英] FB Connect: (417) Expectation failed

问题描述

我开发了一个简单的ASP.NET应用程序，它工作正常，但现在我无法得到用户信息;我得到这个消息：

I developed a simple ASP.NET app, it was working fine, but now I can't get user info; I am getting this message:

远程服务器返回错误：（417）预期失败。

The remote server returned an error: (417) Expectation failed.

和这里的code我使用的是：

and here's the code I'm using:

Dim FBUser As Facebook.Schema.user = Nothing
Dim connectSession As Facebook.Session.ConnectSession
Dim FBApi As Api

connectSession = New Facebook.Session.ConnectSession(ConfigurationManager.AppSettings("AppKey"), ConfigurationManager.AppSettings("AppSecret"))

If connectSession.IsConnected() Then
    FBApi = New Api(connectSession)
    Try
        FBUser = FBApi.Users.GetInfo()
        '' do some work
    Catch ex As Exception
        FBUser = Nothing
        '' other work
    End Try
End If

这是真的很困惑，因为它只是工作罚款2周，现在！

This is really confusing, because it was just working fine for 2 weeks now !!

感谢

推荐答案

我张贴的解决方案，后期很抱歉，但它竟然是一些ISP相关的东西。添加此行web配置将帮助：

I'm sorry for posting the solution that late, but it turned out to be some ISP related stuff. Adding this line to web config will help:

  <system.net>
    <settings>
      <servicePointManager expect100Continue="false"/>
    </settings>
  </system.net>

或者，它相当于由code。

Or it equivalent by code.
