我正在使用 ServiceStack 构建一个 REST Web 服务。我想允许跨域请求,所以我注册了 CorsFeature 插件。
我的 AppHost 如下所示:
public class HomeAppHost : AppHostHttpListenerBase
{
public Context Context { get; set; }
public HomeAppHost(Context context)
: base("HomeAutomation", typeof(HomeInterfaceService).Assembly)
{
Context = context;
}
public override void Configure(Funq.Container container)
{
Plugins.Add(new CorsFeature());
Routes
.Add<HomeInterface>("/HomeInterface")
.Add<HomeInterface>("/HomeInterface/{Id}")
.Add<ViewModel>("/ViewModel")
.Add<FunctionInput>("/Function")
;
}
}
然后,当向服务发出 OPTIONS 请求时,会导致 405 Method Not Allowed:
要求:
OPTIONS /Function HTTP/1.1
Host: localhost:1337
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0 FirePHP/0.7.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: nl,en-us;q=0.7,en;q=0.3
Accept-Encoding: gzip, deflate
DNT: 1
Origin: http://localhost
Access-Control-Request-Method: POST
Access-Control-Request-Headers: content-type
x-insight: activate
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
回复:
HTTP/1.1 405 Method Not Allowed
Content-Length: 1837
Content-Type: application/xml
Server: Microsoft-HTTPAPI/2.0
Date: Fri, 15 Feb 2013 20:19:33 GMT

向服务添加一个空的 Options 方法确实可以防止触发 405。但是,响应似乎是空的:
HTTP/1.1 200 OK
Transfer-Encoding: chunked
Server: Microsoft-HTTPAPI/2.0
Date: Sat, 16 Feb 2013 08:44:21 GMT
添加以下内容也会给我一个空响应:
RequestFilters.Add((httpReq, httpRes, requestDto) =>
{
//Handles Request and closes Responses after emitting global HTTP Headers
if (httpReq.HttpMethod == "OPTIONS")
httpRes.End();
});
我不得不将 httpReq.Method 更改为 httpReq.HttpMethod 并将 httpRes.EndServiceStackRequest() 更改为 httpRes.End()。它是否正确?
