WCF Config to fix 已超出最大字符串内容长度配额 (8192)

Question

我收到一个错误

已超过最大字符串内容长度配额 (8192)

我知道我需要修改我的 WCF 配置，但我无法让它工作。这是我目前所拥有的：我尝试使用内置的 WCF 编辑器。

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

    <client>
      <remove contract="IMetadataExchange" name="sb" />
      <endpoint address="" binding="netTcpRelayBinding" contract="IMetadataExchange"
        name="sb" />
    </client>
    <services>
      <service name="SvcLibrary.Service1">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8732/Design_Time_Addresses/SvcLibrary/Service1/"/>
          </baseAddresses>
        </host>
        <!-- Service Endpoints -->
        <!-- Unless fully qualified, address is relative to base address supplied above -->
        <endpoint address="" binding="wsHttpBinding" contract="SvcLibrary.IService1">
          <!-- 
              Upon deployment, the following identity element should be removed or replaced to reflect the 
              identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
              automatically.
          -->
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <!-- Metadata Endpoints -->
        <!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. -->
        <!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- 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>
  </system.serviceModel>

SCB 关于绑定是正确的：

<bindings>
      <wsHttpBinding>
        <binding>
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        </binding>
      </wsHttpBinding>
    </bindings>

但我也收到错误“已超出最大字符串内容长度配额 (8192)”，因为我需要按如下方式修改客户端应用程序：

 <basicHttpBinding>
        <binding name="BasicHttpBinding_IXRMService" 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="65536" maxArrayLength="16384"
            maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None"
              realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>

默认的maxStringContentLength设置为8192我把它增加到65536，问题解决了

您需要按如下方式更改绑定部分：

<bindings>
      <wsHttpBinding>
        <binding maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
            maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
        </binding>
      </wsHttpBinding>
    </bindings>

您的端点指定它正在使用 wsHttpBinding，但您只配置了 basicHttpBinding。

这意味着您的服务将只使用默认值

由于您指定的值很大，您可能需要查看这些值

-- 更新

为绑定添加了 maxReceivedMessageSize 属性。

您还可以确认您是否在客户端进行了任何更改。基本上客户端和服务器配置都应该匹配。

您设置了正确的属性 (maxStringContentLength)，但绑定错误。问题是您正在为basicHttpBinding 定义配置，但在服务端点上使用wsHttpBinding。将绑定配置更改为wsHttpBinding，它应该可以正常工作（您可能想验证是否需要通过wsHttpBinding 提供的WS-* 功能，您也可以将端点的绑定更改为basicHttpBinding，这也可以，只要你不需要支持分布式事务等）
