【问题描述】：

我是 WCF 的新手，请帮帮我。我收到此错误。我在互联网上搜索过这个问题，我有很多解决方案，但是当我应用这些解决方案时。我面临的一些新问题。所以请给我一个有效的解决方案。

已超出传入邮件的最大邮件大小配额 (65536)。要增加配额，请在适当的绑定元素上使用 MaxReceivedMessageSize 属性。

服务 Web.config 文件。

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="WSHttpBinding_IService1" maxBufferSize="2147483647"
      maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>
<services>
  <service name="WcfServiceZone_Store.Service1" behaviorConfiguration="metadataBehavior">
    <!-- Service Endpoints -->
    <endpoint address="" binding="wsHttpBinding" contract="WcfServiceZone_Store.IService1">
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="metadataBehavior">
      <!-- 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>
  </serviceBehaviors>
</behaviors>

客户端 Web.config 文件：

<system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="WSHttpBinding_IService1" maxBufferSize="2147483647"
      maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:50274/Service1.svc" binding="wsHttpBinding" contract="ServiceReference1.IService1">
    <identity>
      <dns value="localhost" />
    </identity>
  </endpoint>
</client>

请告诉我，我需要在哪方面进行更改。

【参考方案1】：

您需要在双方（服务器和客户端）上进行更改，但您需要进行适当的绑定 - 您的服务（和客户端）实际使用的绑定！

因此，在您的情况下，在您的服务器端，服务配置为使用wsHttpBinding：

<service name="WcfServiceZone_Store.Service1" behaviorConfiguration="metadataBehavior">
   <endpoint address="" binding="wsHttpBinding" contract="WcfServiceZone_Store.IService1">
                                 *************

但是您已经在 basicHttpBinding 上定义了更高的值.....当然，这是行不通的！

<bindings>
   <basicHttpBinding>
    ****************   this doesn't match with the defined binding on your endpoint!

而且您也没有引用您定义的新绑定配置 - 您需要告诉 WCF 才能实际使用这些新绑定值！

所以你需要在服务器上这样做：

<system.serviceModel>
<bindings>
  <wsHttpBinding>
    <binding name="BindingWithMaxSizeIncreased" 
         maxBufferPoolSize="2147483647" 
         maxReceivedMessageSize="2147483647">
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
              maxArrayLength="2147483647" maxBytesPerRead="2147483647" 
              maxNameTableCharCount="2147483647" />
    </binding>
  </wsHttpBinding>
</bindings>

<services>
  <service name="WcfServiceZone_Store.Service1" behaviorConfiguration="metadataBehavior">
    <!-- Service Endpoints -->
    <endpoint 
        address="" 
        binding="wsHttpBinding" 
        bindingConfiguration="BindingWithMaxSizeIncreased"  -- use those new values!
        contract="WcfServiceZone_Store.IService1">
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>

客户端也一样：

为

正确

绑定定义绑定参数（wsHttpBinding - 不是basicHttpBinding） 将对bindingConfiguration 的引用添加到<endpoint>，以便实际使用这些值

【讨论】：

wsHttpBinding 没有 maxBufferSize 属性。

【参考方案2】：

对于 customBinding 添加具有以下值的 httpTransport：

 <system.serviceModel>
    <bindings>
        <customBinding>
            <binding name="QueryDocumentWSPortBinding">
                <textMessageEncoding messageVersion="Soap12" />

              <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
                            maxReceivedMessageSize="2147483647" allowCookies="false" authenticationScheme="Anonymous"
                            bypassProxyOnLocal="false" decompressionEnabled="true" hostNameComparisonMode="StrongWildcard"
                            keepAliveEnabled="true" maxBufferSize="2147483647" proxyAuthenticationScheme="Anonymous"
                            realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
                            useDefaultWebProxy="true" />
            </binding>
            ....
