呼!好的...我解决了我的Wcf / Linq错误(并且学到了很多东西 - 一系列的博客帖子将跟随下一个弱点)。现在我需要部署。我们在Mosso / Rackspace云上运行,目前该环境在部分信任环境中运行。
为了简单起见,我在我的Wcf服务中添加了一个方法,该方法几乎没有。
public string Echo(string what)
{
return what;
}
我构建了所有内容,并使用以下Web.Config(仅限相关部分)将其发送到测试服务器...是的,我需要在暴露危险方法之前明显添加安全性,但是现在我想要匿名运行的东西:)
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding name="BasicAnonymous">
<security mode="None"/>
</binding>
</basicHttpBinding>
</bindings>
<behaviors>
<serviceBehaviors>
<behavior name="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior"
name="FooBar.Backend.Web.Services.CoreDataWcfService">
<endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicAnonymous" contract="FooBar.Backend.Web.Services.ICoreDataWcfService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
<baseAddressPrefixFilters>
<add prefix="http://backend.FooBar.com"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
所以,关闭我用控制台应用程序以最简单的方式调用它。我添加服务参考,它添加罚款。然后我称之为(我为了简洁起见了非活动代码)...
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using CoreWcfHarness.CoreDataServiceReference;
namespace CoreWcfHarness
{
class Program
{
static void Main(string[] args)
{
var context = new CoreDataWcfServiceClient();
var echoval = context.Echo("Hello World!");
Console.WriteLine(String.Format("{0}\n", echoval));
Console.ReadKey();
}
}
}
而blammo。我受到了例外的打击。

这很简单。任何熟悉中等信任环境和/或堆栈跟踪好的人?
谢谢!

“请求失败”可能是一些事情。
看起来最可能的原因是请求未到达服务器。您应该检查服务器日志以确保将请求发送到正确的位置。
