IIS 问题上承载的 WCF 工作流

Question

我已经在 IIS 上托管了 WCF WF。从客户端，我正在尝试访问IIS上的服务，但出现以下错误：

The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'GetData'. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 197, position 41.

这是我的 web.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="DataAccess.SharePoint.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
  </configSections>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <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>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
  <applicationSettings>
    <DataAccess.SharePoint.Properties.Settings>
      <setting name="DataAccess_SharePoint_Officecms_Lists" serializeAs="String">
        <value>http://site/_vti_bin/lists.asmx</value>
      </setting>
    </DataAccess.SharePoint.Properties.Settings>
  </applicationSettings>
</configuration>

这是我的客户端app.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IService" closeTimeout="00:01:00"
                    openTimeout="00:10:00" 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="2147483647"

                                  />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://server2008/Services/Search.xamlx"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IService"
                contract="SearchService.IService" name="BasicHttpBinding_IService" />
        </client>
    </system.serviceModel>
</configuration>

你能验证我的配置，并修改和解释我做错了什么吗？

您是在服务器还是客户端上收到此消息？ 如果从客户端到服务器的消息大于默认限制，则需要在 web.config 中增加该限制。

您可以通过将其添加到系统中来控制 web.config 中的绑定。服务模型部分：

  <bindings>
      <basicHttpBinding>
        <binding>
          <readerQuotas maxStringContentLength ="<your max here>"/>
        </binding>
      </basicHttpBinding>
    </bindings>
