WCF入门（一）--Request Entity Too large 传输的数据量过大

通过WCF进行数据的查询或者添加的时候，如果数据量过大，一般会报出如下的错误：

1、已超过传入消息(65536)的最大消息大小配额。若要增加配额，请使用相应绑定元素上的MaxReceivedMessageSize 属性。

2、远程服务器返回了意外反应（413）Request Entity too large。

3、远程服务器返回了意外反应（400）Bad Request。

具体的解决方案：

服务端返回数据给客户端报错

在客户端的配置文件中，主要修改maxReceivedMessageSize

<system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_Default" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>

2、客户端传数据给服务端报错

修改服务端web.config

<system.serviceModel>
    <bindings>
      <basicHttpBinding>                                                                                                       <!--其实要修改所有的服务，不管是服务端还是客户端，Binding那边增加一个没有设置名字的默认配置就OK了-->
        <binding   closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00"
       maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
        </binding >
        </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="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" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="1" />
  </system.serviceModel>
