WCF Rest POST方法正在获取空json字符串

WCF Rest POST始终获取空字符串。我已经花了一个多星期的时间去探索，但到目前为止没有运气

我的服务代码：

[ServiceContract]
public interface ISaveSurvey
{   
    [WebInvoke(Method = "POST",
           ResponseFormat = WebMessageFormat.Json,
           RequestFormat = WebMessageFormat.Json,               
           BodyStyle = WebMessageBodyStyle.Wrapped,
           UriTemplate = "/SSS")]        
    bool InsertSiteSurveyInfo(string jsonString);
}

Web配置：

    <compilation debug="false" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="Honeywell.HBS.SiteSurvey.SaveSurvey" behaviorConfiguration="SaveSurvey">
        <endpoint address="" binding="webHttpBinding" contract="Honeywell.HBS.SiteSurvey.ISaveSurvey" behaviorConfiguration="wcfRestBehavior"/>
      </service>
    </services>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

我附加了w3wp进程并尝试调试服务，json字符串总是为null。但是我使用fiddler截获了json字符串被发布的请求，而服务实现代码总是为null。

这是计划中的行为。您的服务不知道如何映射您传递的数据。 如果要将json内容作为字符串传递，则应将其包装如下：

data: JSON.stringify({ jsonString: "your_data" })
