Facebook应用获得HTTP 500.23错误;翻译？

标签： c# .net facebook facebook-c#-sdk

我正在构建我的第一个脸书应用程序，我遇到了问题，我对这一切都太新了解了解最新情况，并希望有经验的人可以理解。这是应用程序的链接，以及错误：

http://apps.facebook.com/nowiknow/

错误：

  

HTTP错误500.23 - 内部服务器   错误已设置ASP.NET设置   检测到不适用于   集成管理管道模式。

我在DiscountASP.Net（littleappbin.com/whoremovedme/）上托管我的应用程序。我的应用程序池管道模式配置为集成，服务器正在使用 IIS7 。据我所知，我的代码成功请求了所需的权限，但是当被重定向到应用程序时出现了问题。

这是我的 web.config 文件：

    <section name="canvasSettings" type="Facebook.Web.CanvasConfigurationSettings, Facebook.Web" />

我为这个凌乱的代码道歉，其中很大一部分来自我正在乱砍的不同样本。

答案 0 :(得分：2)

基本上，你把一大堆混合在一起的东西放在一起。具体来说，列出的所有程序集都是.net 3.5程序集，但您的编译设置为4.0。将您的web.config文件更改为：

<configuration>
 <configSections>
    <section type="Facebook.FacebookConfigurationSection, Facebook" name="facebookSettings" allowLocation="true" allowDefinition="Everywhere" />
    <section name="canvasSettings" type="Facebook.Web.CanvasConfigurationSettings, Facebook.Web" />
 </configSections>
 <facebookSettings appSecret="xxxxxxxxxx" appId="xxxxxxxxxxxxxx" cookieSupport="true"/>
 <canvasSettings canvasPageUrl="http://apps.facebook.com/nowiknow" canvasUrl="http://www.littleappbin.com/whoremovedme" authorizeCancelUrl="http://facebook.com"/>
 <system.web>
  <compilation debug="true" targetFramework="4.0" />
 </system.web>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
  <handlers>
      <add name="facebookredirect.axd" verb="*" path="facebookredirect.axd" type="Facebook.Web.FacebookAppRedirectHttpHandler, Facebook.Web" />
  </handlers>
 </system.webServer>
 <connectionStrings>
  <add name="xxxxxConnectionString" connectionString="Data Source=xxxxx;Initial Catalog=xxxxx;Persist Security Info=True;User ID=xxxxx;Password=xxxxxx" providerName="System.Data.SqlClient"/>
 </connectionStrings>
</configuration>

还要确保将Framework目标设置为4.0。有关详细信息，请参阅此处：http://msdn.microsoft.com/en-us/library/bb398197.aspx
