Jquery CORS支持WCF休息和剑道

我在wcf休息服务公司工作。我需要允许cors支持跨域访问。我读了文章，得到了2种方法

第一种方法是在global.asax中的应用程序_beginrequest事件中添加http头。这对我来说很好。我使用jquery使用剑道图绑定测试了这一点。图表填充在IE、Chrome和Firefox中。在global.asax中启用cors的工作代码为

    protected void Application_BeginRequest(object sender, EventArgs e)
    {

        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
        if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
        {
            //These headers are handling the "pre-flight" OPTIONS call sent by the browser
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET");
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Authorization, Origin, Content-Type, Accept, X-Requested-With");
            HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
            HttpContext.Current.Response.End();
        }
    }

但是我需要配置cors enabled属性，所以我遵循了这个步骤。我复制并运行了成功的服务。但在我在endpoint中启用此行为后，客户端在Chrome和Firefox中没有显示图表。因此，未启用跨域。我说得对吗？我想念这里

我的新服务课程是

public class CorsEnabledBehavior : BehaviorExtensionElement, IEndpointBehavior
{
    public void AddBindingParameters(ServiceEndpoint endpoint, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
    {

    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.ClientRuntime clientRuntime)
    {

    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, System.ServiceModel.Dispatcher.EndpointDispatcher endpointDispatcher)
    {
        var requiredHeaders = new Dictionary<string, string>();

        requiredHeaders.Add("Access-Control-Allow-Origin", "*");
        requiredHeaders.Add("Access-Control-Request-Method", "POST,GET,PUT,DELETE,OPTIONS");
        requiredHeaders.Add("Access-Control-Allow-Headers", "X-Requested-With,Content-Type");

        endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new CorsEnabledMessageInspector(requiredHeaders));
    }

    public void Validate(ServiceEndpoint endpoint)
    {

    }

    public override Type BehaviorType
    {
        get { return typeof(CorsEnabledBehavior); }
    }

    protected override object CreateBehavior()
    {
        return new CorsEnabledBehavior();
    }

}

public class CorsEnabledMessageInspector : IDispatchMessageInspector
{
    Dictionary<string, string> requiredHeaders;
    public CorsEnabledMessageInspector(Dictionary<string, string> headers)
    {
        requiredHeaders = headers ?? new Dictionary<string, string>();
    }

    public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext)
    {
        return null;
    }

    public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
    {
        var httpHeader = reply.Properties["httpResponse"] as HttpResponseMessageProperty;
        foreach (var item in requiredHeaders)
        {
            httpHeader.Headers.Add(item.Key, item.Value);
        }
    }
}

公共类CorsEnabledBehavior:BehaviorExtensionElement，IEndpointBehavior

我的网络配置是

你能帮我找到我想念的地方吗？

我做完了。我使用global.asax启用了cors并成功运行。问题是iecors.js。在IE 8和9中启用cors不起作用。所有其他浏览器工作正常

我想给你投票10000次。我尝试了所有方法-配置文件、自定义IDispatchMessageInspector来添加标题（与您在asax中添加的标题/值相同）-“GET”始终有效，但其他所有方法都被取消。将此移动到。asax解决了此问题，谢谢！请在这方面帮助我：-
