WCF Web 服务中的最大读者配额问题

Question

格式化程序在尝试反序列化消息时抛出异常：尝试反序列化参数http://tempuri.org/:GetFileResult 时出错。 InnerException 消息是“反序列化 WindowsClient.CloudServiceProxy.GetFileResponse 类型的对象时出错。读取 XML 数据时已超出最大数组长度配额 (16384)。可以通过更改创建 XML 阅读器时使用的 XmlDictionaryReaderQuotas 对象的 MaxArrayLength 属性来增加此配额。第 1 行，位置 41572.'。有关详细信息，请参阅 InnerException。 我得到这个问题 服务器 web.config 是

<system.serviceModel>
    <services>
  <service behaviorConfigura

tion="CloudServiceBehaviour" name="Web.CloudService">
        <endpoint name="CloudServiceClientEndPoint" bindingConfiguration="CloudBindingConfig" address="http://localhost:53243/CloudService.svc" binding="wsHttpBinding" contract="Web.ICloudService"></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="CloudServiceBehaviour">
          <serviceMetadata httpGetEnabled="True" httpGetUrl=""/>
          <serviceDebug includeExceptionDetailInFaults="true" />

        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <wsHttpBinding>
        <binding name="CloudBindingConfig" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="200" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        </binding>
      </wsHttpBinding>
    </bindings>
  </system.serviceModel>

而客户端 web.config 是，

<system.serviceModel>
        <bindings>
            <wsHttpBinding>
              <binding name="CloudServiceClientEndPoint" closeTimeout="00:01:00"

                <reliableSession ordered="true" inactivityTimeout="00:30:00"
                  enabled="false" />
                <security mode="Message">

                </security>
              </binding>
            </wsHttpBinding>
        </bindings>
        <client>
          <endpoint address="http://localhost:53243/CloudService.svc" binding="wsHttpBinding"
            contract="CloudServiceProxy.ICloudService" name="CloudServiceClientEndPoint" />
        </client>
    </system.serviceModel>

Answer 1

由于错误是在反序列化 GetFileResponse 对象时出现的，这告诉您问题出在客户端堆栈中。

您的客户端绑定正在使用 wsHttpBinding 的默认配置，因为您省略了在端点上指定 bindingConfiguration 名称。尝试将bindingConfiguration="CloudServiceClientEndPoint" 添加到端点元素，然后您的 readerQuotas 设置的大值将被拾取。
