使用 MTOM 流式传输二进制数据的 WCF Web 服务出现错误"An error occurred while receiving the HTTP response ***"

我必须开发一个能够发送带有附件的电子邮件的web服务，以及一个使用wcf和mtom进行序列化的客户端。我使用以下工具进行工作：

Windows 7 Professional x64Microsoft Visual Studio 2012Microsoft Development Server/IIS Express 8.0用户：管理员

每次我尝试在客户端中使用消息协定中自定义类的Web服务时，我都会收到错误"接收到对http://localhost:2364/Service1.svc的HTTP响应时出错。这可能是由于服务端点绑定未使用HTTP协议。这也可能是由于服务器中止了HTTP请求上下文(可能是由于服务关闭)。有关详细信息，请参阅服务器日志。

现在，我只是尝试设置一个简单的测试服务和一个简单测试客户端。我尝试了以下事情，但总是得到相同的错误，而使用Web服务中只在请求和响应中使用简单字符串的方法工作得很好，没有任何错误。

Visual Studio 2012和IIS Express 8.0 中集成的Microsoft Development Server上出现相同错误
在客户端和服务的配置中使用basicHttpBinding或wsHttpBinding时出现相同错误
已尝试在两台服务器上生成日志文件。IIS Express Server会在其他文件夹中生成一些日志，而不是使用配置文件中的设置。Microsoft Development Server不会生成任何内容。
我使用svctraceviewer.exe查看了少数生成的日志文件，只看到了一些操作码为MODULE_SET_RESPONSE_ERROR_STATUS的警告。我无法理解这些信息。
我尝试为localService和networkService启用对指定文件夹的读/写权限，但没有结果。
我试图使用RawCap探查localhost并使用wireshark查看结果，但输出文件有0个字节(这肯定是另一个问题)。

如果您需要更多信息，请告诉我。

谢谢！

以下是我的服务和客户端代码和配置(仅用于测试)：

客户端：app.config:

name="WSHttpBinding_IService1">
<identity>
<userPrincipalName value="AresAdmin" />
</identity>
</endpoint>
</client>
</system.serviceModel>
</configuration>

客户端：Form1.cs

...
private void button1_Click(object sender, EventArgs e)
{
ServiceReference1.IService1 testService = new ServiceReference1.Service1Client();
ServiceReference1.ServiceRequest testInput = new ServiceReference1.ServiceRequest();
ServiceReference1.ServiceResponse testOutput = new ServiceReference1.ServiceResponse();
BinaryFormatter formatter = new BinaryFormatter();
MemoryStream inoutStream = new MemoryStream();
testInput.Type = "TestType";
String test = "TestContent";
testInput.Contents = new MemoryStream();
formatter.Serialize(testInput.Contents, test);
//testInput.Contents.Position = 0;
testService.TestCase(testInput);

MessageBox.Show("Done!");
}
...

我在web.config(端点等)中看不到任何服务配置数据

<services>
<service behaviorConfiguration="..." name="[Namespace].Service1">
<endpoint address="" binding="basicHttpBinding" bindingNamespace="..." bindingConfiguration="..." contract="[Namespace].IService1">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:5000/Service1"/>
...

您可以在运行时配置端点(基本上是在自托管服务中)，但对于简单的场景和IIS基础结构。。。？
