  WCF:(400) Bad Request 错误解决方案



报错信息:远程服务器返回了意外响应: (400) Bad Request。


经过几次调试,发现小数据量不会出现此错误,如何传输大数据量呢,经过网上搜索和几 次测试发现,只要在服务端和客户端同时增大以下几个配置项。


服务器端:


<system.serviceModel>

    <bindings>

      <basicHttpBinding>

        <binding maxBufferPoolSize="5242880000" maxBufferSize="655360000" maxReceivedMessageSize="655360000">

          <security mode="None"/>

        </binding>

      </basicHttpBinding>

    </bindings>

    <services>

      <service name="test">

        <endpoint binding="basicHttpBinding" name="test" contract="Test_Service.Test"/>

      </service>

    </services>

 

    <behaviors>

      <serviceBehaviors>

        <behavior>

          <!-- 为避免泄漏元数据信息,请在部署前将以下值设置为 false 并删除上面的元数据终结点 -->

          <serviceMetadata httpGetEnabled="true"/>

          <!-- 要接收故障异常详细信息以进行调试,请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -- >

          <serviceDebug includeExceptionDetailInFaults="true"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

  </system.serviceModel>


 


同样在客户端也需要增大与服务器端相同的配置:


  <system.serviceModel>

    <bindings>

      <basicHttpBinding>

        <binding name="BasicHttpBinding_ITest" closeTimeout="00:01:00"

             &nb sp;  openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

             &nb sp;  allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"

             &nb sp;  maxBufferSize="655360000" maxBufferPoolSize="5242880000" maxReceivedMessageSize="655360000"

             &nb sp;  messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"

             &nb sp;  useDefaultWebProxy="true">

          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"

            maxBytesPerRead="4096" maxNameTableCharCount="16384" />

          <security mode="None">

            <transport clientCredentialType="None" proxyCredentialType="None"

              realm="" />

            <message clientCredentialType="UserName" algorithmSuite="Default" />

          </security>

        </binding>

      </basicHttpBinding>

    </bindings>

    <client>

      <endpoint address="http://www.test.com/Test.svc"

        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ITest"

        contract="TestService.ITest" name="BasicHttpBinding_ITest" />

    </client>

  </system.serviceModel>
