Question

我有针对.NET Framework 4的WCF REST服务目标。我使用 WebScriptEndPoint 的标准端点并使用基本身份验证

当我使用Jquery使用此服务时，当我在同一服务应用程序中使用该页面时，它正常工作，即http://localhost。但是，如果我使用不同的Web应用程序（即http://localhost:20984）使用此服务，则它无效。当我尝试http://localhost/WebHttpBindTest/JSONAPIDemo.aspx

时，小提琴手会显示出来

但是当我尝试使用网络应用时

GET http://localhost/WebHttpBindTest/Service.svc/GetData?value=fdsafa&callback=jsonp1337264499382&_=1337264533468 HTTP/1.1

使用网络应用页面发送时，请参阅授权标题。

看起来这是跨域问题。我确实启用了crossdomainscriptAccess，即

这是服务合同：

[ServiceContract]
public interface IService
{
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    [OperationContract]
    string GetData(string value);

}

的web.config

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
    <services>
      <service name="Service" behaviorConfiguration="auth">
        <endpoint address="" kind="webScriptEndpoint" contract="IService" />
      </service>
    </services>
    <standardEndpoints>
      <webScriptEndpoint>
        <standardEndpoint crossDomainScriptAccessEnabled="true">
        </standardEndpoint>
      </webScriptEndpoint>
    </standardEndpoints>
    <behaviors>
      <serviceBehaviors>
        <behavior name="auth">
          <serviceAuthorization serviceAuthorizationManagerType="BasicAuth.BasicAuthorization, BasicAuth" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

如果要通过jQuery访问端点，则应使用<webHttpEndpoint>标准端点，而不是<webScriptEndpoint>。 webScriptEndpoint应该仅用于使用ASP.NET AJAX框架的客户端。
