WCF中的最大数组长度配额异常

Question

我正在编写一个WCF服务来上传文件,但是当字节数组有超过16384个元素时,它会抛出异常.

这是一个例外细节:

格式化程序在尝试反序列化消息时抛出异常:反序列化操作"CreateDocument"的请求消息正文时出错.读取XML数据时已超出最大数组长度配额(16384).通过更改创建XML阅读器时使用的XmlDictionaryReaderQuotas对象上的MaxArrayLength属性,可以增加此配额.第1行,第22862位.

客户端和服务器的配置将最大阵列长度配额设置为2147483647.

客户端配置:

<system.serviceModel>
  <bindings>
   <basicHttpBinding>
    <binding name="BasicHttpBinding_IDocumentLibraryService" 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="32" 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>
  <client>
   <endpoint address="http://localhost:50764/DocumentLibraryService.svc"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDocumentLibraryService"
    contract="DocumentLibrary.IDocumentLibraryService" name="BasicHttpBinding_IDocumentLibraryService" />
  </client>

服务器配置:

<bindings>

            <basicHttpBinding>
                <binding name="BasicHttpBinding_IDocumentLibraryService" 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="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>
        <services>

            <service name="BasicHttpBinding_IDocumentLibraryService">

                <clear />
                <endpoint address="mex" binding="mexHttpBinding" name="mex" contract="Peninsula.DocumentLibrary.ServiceLayer.IDocumentLibraryService" />
                <endpoint binding="basicHttpBinding" name="DocumentLibraryService" contract="Peninsula.DocumentLibrary.ServiceLayer.IDocumentLibraryService" address=""
                          bindingConfiguration="BasicHttpBinding_IDocumentLibraryService"/>
            </service>
        </services>

Answer 1

我需要做的就是将 web.config 文件中的服务名称更改为带有命名空间的完整服务名称：

<service name="SampleNameSpace.DocumentLibraryService">

                <clear />
                <endpoint address="mex" binding="mexHttpBinding" name="mex" contract="Peninsula.DocumentLibrary.ServiceLayer.IDocumentLibraryService" />
                <endpoint binding="basicHttpBinding" name="DocumentLibraryService" contract="Peninsula.DocumentLibrary.ServiceLayer.IDocumentLibraryService" address=""
                          bindingConfiguration="BasicHttpBinding_IDocumentLibraryService"/>
            </service>
