我使用ASP.NET Web Api编写了一个RESTful API.现在我试图让它返回一个控制器允许的动词.我试图使用以下代码：
[AcceptVerbs("OPTIONS")]
public HttpResponseMessage Options()
{
var response = new HttpResponseMessage(HttpStatusCode.OK);
response.Headers.Add("Access-Control-Allow-Origin","*");
response.Headers.Add("Access-Control-Allow-Methods","POST");
response.Headers.Add("Allow","POST");
return response;
}
但是,我没有在我的回复中得到一个允许标题,我收到一个500内部服务器错误.调试时收到以下错误：
{"Misused header name. Make sure request headers are used with HttpRequestMessage,response headers with HttpResponseMessage,and content headers with HttpContent objects."}
是否可以设置该标题？
