我试图允许来自托管在localhost:80的JavaScript应用程序的POST请求到托管在不同端口的WCF REStful服务,但不知何故它不起作用。我已经尝试向头添加自定义属性,并在我的服务的JSONData
方法中以编程方式添加它,但我仍然在我的回复中收到'405方法不允许'。这里有什么合适的方法?如何将跨域支持添加到WCF服务
这是我的接口:
namespace RestService
{
public class RestServiceImpl : IRestServiceImpl
{
#region IRestServiceImpl Members
public string JSONData()
{
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
return "Your POST request";
}
#endregion
}
}
和服务代码:
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Web.Script.Services;
namespace RestService
{
[ServiceContract]
public interface IRestServiceImpl
{
[OperationContract]
[ScriptMethod]
[WebInvoke(Method = "POST",
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.Bare,
UriTemplate = "export")]
string JSONData();
}
}
最后的配置:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="RestService.RestServiceImpl" behaviorConfiguration="ServiceBehaviour">
<endpoint address ="" binding="webHttpBinding" contract="RestService.IRestServiceImpl" behaviorConfiguration="web">
</endpoint>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehaviour">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
</system.webServer>
</configuration>
这将是一个非常好的问题,如果你描述什么“,但不知何故不工作”的意思。 –
我已更新说明。 –
