错误：已超出传入邮件 (65536) 的最大邮件大小配额

Question

我收到此错误消息

已超出传入邮件的最大邮件大小配额 (65536)

当我尝试将文件 (+-160KB) 上传到我的 WCF 服务时。我试图增加以下属性的值：

maxReceivedMessageSize,
maxBufferPoolSize,
maxArrayLength,
maxStringContentLength, 

但我没有运气。我的 WCF 配置文件如下所示：

<system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="wsBinding" maxReceivedMessageSize="3200000" maxBufferPoolSize="100000000"  >
          <readerQuotas maxArrayLength="1000000000" maxStringContentLength="3200000" />
        </binding>
      </wsHttpBinding>
    </bindings>
    <client />
    <services>
      <service behaviorConfiguration="PMSService.Thomolosha"
        name="PMSService.Thomolosha" >
        <endpoint address="" binding="wsHttpBinding"  contract="PMSService.ThomoloshaDeclaration">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding"  contract="IMetadataExchange" />
      </service>
      <service behaviorConfiguration="PMSService.Arekwe"
              name="PMSService.Arekwe">
        <endpoint address="" binding="wsHttpBinding" contract="PMSService.ArekweDeclaration">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="PMSService.Thomolosha">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
        <behavior name="PMSService.Arekwe">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

我的 Winform 配置如下所示：

Answer 1

听起来您在服务端遇到了错误（当您尝试上传时）。根据您发布的服务配置，您已为 maxReceivedMessageSize 和其他设置设置了更高的限制，但您从未分配该绑定到您的服务端点，因此 WCF 使用默认值为maxReceivedMessageSize (65536)。

您需要通过 endpoint 元素的 bindingConfiguration 属性将定义的绑定 (wsBinding) 分配给服务端点，如下所示：

<endpoint address="" 
          binding="wsHttpBinding"
          bindingCongifuration="wsBinding"
          contract="PMSService.ThomoloshaDeclaration">

现在服务将使用您定义的绑定配置，该配置具有更大的大小。
