asp.net – 配置错误’Facebook.FacebookConfigurationSection’

2023年4月22日 222次阅读

我创建了一个示例asp.net 4.0应用程序,其中包含一个Facebook Connect按钮.我在IIS上运行该网站.

该网站工作正常.但是每当我在IIS中部署它时,应用程序都会给我错误.

更改所有值后,错误的根本原因是更改应用程序池中的“空闲超时”.

以下是我为重现此错误所做的工作：

1.建立网站,让它通过IIS运行.(在visual studio中,通过更改网站属性在自定义网络服务器中运行).

2.将应用程序池中的空闲超时(在高级设置中)更改为1或2分钟.

3.运行网站,通过Facebook登录.然后不要刷新它. 1或2分钟后,您将收到此错误.

错误：

代码背后：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Dynamic;
using Facebook;

public partial class FacebookTest : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        FacebookApp fbApp = new FacebookApp();

        if (fbApp.Session != null)
        {
            dynamic myinfo = fbApp.Get("me");
            String firstname = myinfo.first_name;
            String lastname = myinfo.last_name;
            lblFBStatus.Text = "you signed in as " + firstname + 
                               " " + lastname + " to use this credential ";

        }
        else
        {
            lblFBStatus.Text = "Please sign in with facebook";

        } 
    }
}

Web.config文件：

<configuration>  
  <configSections>  
    <section name="facebookSettings" type="Facebook.FacebookConfigurationSection"/>  
  </configSections>  
  <facebookSettings  
     appId="appid"  
     appSecret="appsecret"  
     cookieSupport="true" />  
  <system.web>
    <compilation debug="false" targetFramework="4.0" />
      <httpHandlers>  
        <add verb="*" path="facebookredirect.axd"    
             type="Facebook.Web.FacebookAppRedirectHttpHandler, Facebook.Web" />
      </httpHandlers>  

  </system.web>  
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <modules runAllManagedModulesForAllRequests="true"/>

    <handlers>
      <add name="facebookredirect.axd" verb="*" path="facebookredirect.axd"                                   
          type="Facebook.Web.FacebookAppRedirectHttpHandler, Facebook.Web" />
    </handlers>
  </system.webServer>
</configuration>

最佳答案 在Facebook C#SDK 4.2.1中,我通过创建一个FacebookSettings实例来解决这个错误,明确地将其设置为app Id和密钥(我将它们保存在config的常规AppSettings部分中)并将此显式设置实例传递给FacebookApp构造函数.

例：

using Facebook;

var customSettings = new FacebookSettings();
customSettings.AppId = "PUT_APP_ID_HERE";
customSettings.AppSecret = "PUT_SECRET_HERE";

FacebookApp fbApp = new FacebookApp(customSettings);
// success for me

当我从没有Web上下文的C#单元测试项目运行代码时,我发生了这个错误.
我不需要在网站代码中遇到这个问题.
