为什么 ServiceStack 在HTTP状态代码为 204 无内容时不添加 CORS 标头？

Answer 1

刚刚使用最新版本的ServiceStack进行了测试：

配置ServiceStack以针对null或void回复 204 NoContent ：

SetConfig(new HostConfig {
    Return204NoContentForEmptyResponse = true,
});

添加自定义CORS配置：

Plugins.Add(new CorsFeature(
    allowCredentials: true,
    allowedHeaders: "Content-Type, Allow, Authorization"));

添加返回void和null回复的新服务：

[Route("/void-response")]
public class TestVoidResponse { }

[Route("/null-response")]
public class TestNullResponse { }

public class TestServices : Service
{
    public void Any(TestVoidResponse response) {}

    public object Any(TestNullResponse response)
    {
        return null;
    }
}

致电上述服务：

两个服务都使用CORS标头返回 204 NoContent ：

HTTP/1.1 204 No Content
Cache-Control: private
Content-Length: 0
Vary: Accept
Server: Microsoft-IIS/8.5
X-Powered-By: ServiceStack/4.00 Win32NT/.NET

当HTTP状态代码为204 No Content时，为什么ServiceStack不添加CORS头？
