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 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。
