ServiceStack应OPTIONS请求返回405 [英] ServiceStack returns 405 on OPTIONS request

问题描述

我正在使用ServiceStack构建REST Web服务。我想允许跨域请求，所以我注册了CorsFeature插件。

I'm building a REST webservice using ServiceStack. I want to allow cross-domain request, so I registered the CorsFeature plugin.

我的AppHost如下所示：

My AppHost looks as follows:

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，当对服务发出OPTIONS请求时，结果为405方法不允许：

Then, when an OPTIONS request is made to the service, it results in a 405 Method Not Allowed:

请求：

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

响应：

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

编辑

向服务中添加空的Options方法确实确实防止了405的触发。但是，响应似乎为空：

Adding an empty Options method to the service does indeed prevent the 405 from being triggered. However, the response seems to be empty:

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的响应：

Adding the following also gives me an empty response:

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

我必须将httpReq.Method更改为httpReq.HttpMethod，并将httpRes.EndServiceStackRequest（）更改为httpRes.End （）。这样对吗？

I had to change httpReq.Method to httpReq.HttpMethod and httpRes.EndServiceStackRequest() to httpRes.End(). Is this correct?

推荐答案

不确定这是否是正确的方法，但是我现在使用请求过滤器自己处理CORS：

Not sure whether this is the right way to go, but I'm now handling the CORS myself using a request filter:

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();
    }
});
