ServiceStack (9.54),带有 JQuery AJAX 的 POST 请求。
跨域请求,提示错误“Request not found”。

该服务作为 Windows 服务自托管。防火墙已关闭。

我已经在 ServiceStack 中完成了跨域调用(CORS)的工作,但没有结果。

在网页中,代码(在 localhost 上成功运行)如下。

   jQuery.support.cors = true;
         CallTest()
         {
              $.ajax({
               type: 'POST',
               url: 'http://dev.testhost.com:18162/TestAPI',
               data: JSON.stringify(myRequest),
               contentType: 'application/json',
               dataType: 'json',
               success: function (response, status) {alert(status); },
               error :  error: function (xhr, err) { alert(err);  }
            }
        }
   //in server the code is 
   //1. at appHost
     SetConfig(new ServiceStack.WebHost.Endpoints.EndpointHostConfig
       {

           GlobalResponseHeaders =
           {      //Signal advanced web browsers what HTTP Methods you accept
              { "Access-Control-Allow-Origin", "*" },
              { "Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS" },
              { "Access-Control-Allow-Headers", "Content-Type" },

           }
  }
    //2. request
     [Route("/TestAPI", "POST")]
     [Route("/TestAPI", "GET")]
   public class myRequest
   {

    public string name { get; set; }
    public address[] addresses  { get; set; }
  }
   public class myResponse
  {
    public bool success { get; set; }
    public string message { get; set; }
   }
  // 3. Service
  [AddHeader(ContentType = ContentType.Json)]
    public myResponse  Post(myRequest request)
    {
       return new myResponse();
    }

我在 AppHost 代码中使用不同的设置进行了调试,基于 @mythz 以前的答案, ServiceStack CORS Feature

但这对我不起作用。

更新 1:它适用于 Chrome,不适用于 IE、FIREFOX、OPERA

更新 2:问题已解决,它可以正常工作,非常适合所有经过测试的浏览器(Chrome、IE10、Firefox、Opera 12)。

谢谢@mythz,@Jon

和来自 stackoverflow 问题的@sroes ServiceStack 在 OPTIONS 请求上返回 405

步骤 1. 使用来自@sroes 答案的代码,我在 AppHost.Configure 中替换了 GlobalResponseHeaders,

      Plugins.Add(new CorsFeature());
      RequestFilters.Add((httpReq, httpRes, requestDto) =>
      {
         httpRes.AddHeader("Access-Control-Allow-Origin", "*");

        if (httpReq.HttpMethod == "OPTIONS")
       {
        httpRes.AddHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");
        httpRes.AddHeader("Access-Control-Allow-Headers", 
                           "X-Requested-With, Content-Type");
         httpRes.End();
        }
      }); 

第 2 步:基于@mythz 提议的路由和接受 Options 请求的方法。我在Routes中添加了,实际上并没有为Options创建任何函数。

   Routes
      .Add<ReservationRequest>("/TestAPI/CreateReservation", "POST, GET, OPTIONS");

问题解决了,它对我有用,ServiceStack 摇滚!!

多谢。

更新 3:它也适用于来自 @mythz 的建议代码。

一开始,代码无法编译,因为找不到 EndServiceStackRequest()。

(命名空间 ServiceStack.WebHost.Endpoints.Extensions 中的扩展方法)。

还需要对 System.Web 的引用。httpReq.Method 也是 httpReq.HttpMethod。

最重要的是 Routes for OPTIONS 中的声明。

幸运的是,没有必要添加一个空方法“Options(RequestDto)”。

       using System.Web;
       using ServiceStack.WebHost.Endpoints.Extensions;
       public override void Configure(Container container)
       {             
         Plugins.Add(new CorsFeature()); 
         this.RequestFilters.Add((httpReq, httpRes, requestDto) =>
         {
           //Handles Request and closes Responses after emitting global HTTP Headers
           if (httpReq.HttpMethod == "OPTIONS")
               httpRes.EndServiceStackRequest();
         });

         Routes
           .Add<ReservationRequest>("/TestAPI/CreateReservation", "POST, OPTIONS");
       }

此外,这个问题OPTIONS Verb for Routes with custom CORS headers 是关于同样的问题。

请参阅有关在 OPTION HTTP Requests 上应用 CORS 的早期答案。

您可以使用全局过滤器将 CORS 标头应用于所有OPTION请求,例如:

Plugins.Add(new CorsFeature()); //Registers global CORS Headers

this.RequestFilters.Add((httpReq, httpRes, requestDto) => {
   //Handles Request and closes Responses after emitting global HTTP Headers
    if (httpReq.Method == "OPTIONS") 
        httpRes.EndServiceStackRequest();
});
