Question

我知道这个问题在这里已被多次询问，但我已经完成了其中的每一个，似乎无法让它为我工作。从我的客户端，我试图传入2字节参数并返回byte []但是当参数很小时它工作正常，它会抛出“WCF服务已超过最大数组长度配额（16384）”。

这是我的客户端web.config：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_GenerateDocument" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
          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="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
              realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
        <binding name="BasicHttpBinding_IGenerateDocument" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
          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://localhost:6543/GenerateDocument.svc"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_GenerateDocument"
        contract="NWIS.DocumentGeneratorService.IGenerateDocument" name="NWIS.DocumentGeneratorService.GenerateDocument.svc" />
      <endpoint address="http://localhost:6543/GenerateDocument.svc"
        binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IGenerateDocument"
        contract="DocGenService.IGenerateDocument" name="BasicHttpBinding_IGenerateDocument" />
    </client>
  </system.serviceModel>

这是服务器等价物：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_GenerateDocument" closeTimeout="00:01:00"
          openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:10:00"
          allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
          maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647"
          messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
          useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="5242880" maxArrayLength="2147483646" 
                        maxBytesPerRead="4096" maxNameTableCharCount="5242880"/>
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"
              realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehaviour">
          <!-- 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>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="false" />    
    <services>
      <service name="NWIS.DocumentGeneratorService.GenerateDocument" behaviorConfiguration="ServiceBehaviour">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:6543/"/>
          </baseAddresses>
        </host>
        <endpoint address="http://localhost:6543/GenerateDocument.svc" binding="basicHttpBinding" 
                  contract="NWIS.DocumentGeneratorService.IGenerateDocument"  />
      </service>
    </services>
  </system.serviceModel>

如果有人能够看到400字节的原因，但不是20000字节，我将不胜感激任何指导。

提前感谢你们

您已在服务器端使用超大值定义了绑定配置 - 但您没有使用它！

您需要在服务端点中指定要使用的绑定配置！

因此，请将当前配置更改为：

<service name="NWIS.DocumentGeneratorService.GenerateDocument" behaviorConfiguration="ServiceBehaviour">
    ....
    <endpoint 
        address="http://localhost:6543/GenerateDocument.svc" 
        binding="basicHttpBinding" 
        bindingConfiguration="BasicHttpBinding_GenerateDocument"  <== add this line here!!
        contract="NWIS.DocumentGeneratorService.IGenerateDocument"  />
</service>

然后，希望您的服务实际上会使用您配置的那些值！

抱歉，但是另一个WCF服务已超出最大阵列长度配额（16384）
