c# - 使用 Ajax 请求使用 Wcf 服务时配置文件错误

Question

我在使用 jquery 使用 WCF 服务时遇到了问题。我遇到错误“找不到配置绑定(bind)扩展‘system.serviceModel/bindings/webHttpbinding’。验证此绑定(bind)扩展是否已在 system.serviceModel/extensions/bindingExtensions 中正确注册并且拼写正确。”

这是我的 Web.Config 文件:

<system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" />
      </webHttpBinding>
    </bindings>
    <behaviors>
      <endpointBehaviors>
        <behavior name="RestfulServiceBehavior">
          <webHttp helpEnabled="true"/>
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="WebServiceBehavior">

          <!-- 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>
    <services>
      <service name="WcfService1.RestfulServiceImp" behaviorConfiguration="WebServiceBehavior">
        <endpoint address="" behaviorConfiguration="RestfulServiceBehavior" 
             bindingConfiguration="webHttpBindingWithJsonP" binding="webHttpbinding" contract="WcfService1.IRestfulServiceImp"/>
        <!--<endpoint address="mex" binding="mexHttpBinding" contract="WcfService1.IRestfulServiceImp"/>-->
        <endpoint address="soap" binding="basicHttpBinding" contract="WcfService1.IRestfulServiceImp"/>
      </service>
    </services> 
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"  aspNetCompatibilityEnabled="false"/>

  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>
  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
          switchValue="Information, ActivityTracing"
          propagateActivity="true">
        <listeners>
          <add name="xml"
   type="System.Diagnostics.XmlWriterTraceListener"
   initializeData="c:\log\Traces.svclog" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

这是我的服务名称 RestfulServiceImp，我的契约(Contract)是 IRestfulServiceImp请就此提出宝贵建议。

提前致谢。

您的配置中存在大小写不匹配，

<bindings>
      <webHttpBinding>
        <binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" />
      </webHttpBinding>
    </bindings>

和

<endpoint address="" behaviorConfiguration="RestfulServiceBehavior" 
             bindingConfiguration="webHttpBindingWithJsonP" binding="webHttpbinding" contract="WcfService1.IRestfulServiceImp"/>
        <!--<endpoint address="mex" binding="mexHttpBinding" contract="WcfService1.IRestfulServiceImp"/>-->
        <endpoint address="soap" binding="basicHttpBinding" contract="WcfService1.IRestfulServiceImp"/>

检查 webHttpBinding 中的大小写差异。您使用的是 webHttpbinding 而不是 webHttpBinding。
