Question

我创建了一个通过http上传文件的Web服务，但是在我第一次尝试时，它失败了。

我的网络服务在我的本地计算机的IIS 7上运行，位于ASP.NET 4集成应用程序池下。这是我的web服务的web.config;

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

  <system.serviceModel>

    <behaviors>

      <serviceBehaviors>

        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>

        <behavior name="TransferServiceBehavior">

          <serviceThrottling maxConcurrentCalls="500"
                             maxConcurrentSessions="500" maxConcurrentInstances="500" />  
        </behavior>

      </serviceBehaviors>

    </behaviors>

          <security mode="None">

          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

    <services>

      <service behaviorConfiguration="TransferServiceBehavior" name="TransferService">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration="TransferService"

        </endpoint>
      </service>

    </services>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />

  </system.serviceModel>

 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

  <system.web>
    <!--<httpRuntime maxRequestLength="2097151" />-->
    <httpRuntime maxRequestLength="2097151" 
                 useFullyQualifiedRedirectUrl="true" executionTimeout="14400"   />
  </system.web>

</configuration>

这是客户端的web.config文件;

<configuration>
    <system.web>

                  <message clientCredentialType="UserName" algorithmSuite="Default" />
                </security>
              </binding>
            </basicHttpBinding>
        </bindings>

        <client>
            <endpoint address="http://localhost:81/TransferService.svc" binding="basicHttpBinding"
                bindingConfiguration="BasicHttpBinding_ITransferService" contract="TransferService.ITransferService"
                name="BasicHttpBinding_ITransferService" />
        </client>

    </system.serviceModel>
</configuration>

这是我收到的错误;

远程服务器返回错误：（400）错误请求。

我要上传的文件是217 KB，所以我猜这里的文件大小不是问题。

您认为导致错误的原因是什么？
