wcf服务maxUrlLength maxQueryStringLength maxRequestLength

Question

您好，我有一个WCF服务，网址不工作，如果我调用一个超过260个字符的变量路径，谁有什么建议吗？

<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime maxUrlLength="32766" maxQueryStringLength="2097151" maxRequestLength="2097151" requestValidationMode="2.0" relaxedUrlToFileSystemMapping="true" />
<customErrors mode="Off"/>
 </system.web>
 <system.serviceModel>
<bindings>
</bindings>
<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="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
    <service name="DToolsSynchronizationService.SyncService">
    <endpoint kind="webHttpEndpoint"
    contract="DToolsSynchronizationService.ISyncService" />
  </service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>

我有IIS 7，它在64位windows server 2008中运行

我正在打开HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters

我右键单击参数，选择新的dword 32位值，我将其命名为

MaxFieldLength (我选择十六进制)输入fffe，它是0x0000fffe (65534)

MaxRequestBytes (我选择十六进制)输入1000000，它是0x0000fffe (16777216)

UrlSegmentMaxLength (我选择十六进制)输入fffe，它是0x001fffff (2097151)

就像在图片https://dl.dropbox.com/u/541519/fb/reg.png中一样

我重新启动服务器，但仍然只能看到260个字符。我做错了什么？

我还打开了iis来设置请求过滤为正确的值(最大url长度的查询字符串->enable设置为2097151，最大查询字符串)

您可能可以使用自定义webHttpBinding来解决此问题。

<bindings>
    <webHttpBinding>
        <binding name="longbinding" maxUrlLength="32766 />
    </webHttpBinding>
</bindings>

然后将其用于您的端点

<endpoint kind="webHttpEndpoint"
    contract="DToolsSynchronizationService.ISyncService" 
    bindingConfiguration="longbinding"/>

您可能需要进一步配置绑定，但这应该是一个开始。
