为什么 ServiceStack 在 HTTP 状态码为 204 No Content 时不添加 CORS headers？

Question

为什么在HTTP状态码为204[时ServiceStack不添加CORSheaders =16=]没有内容？

Answer 1

刚刚使用最新版本的 ServiceStack 对此进行了测试：

将 ServiceStack 配置为 return 204 NoContent null 或 void 响应：

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

添加自定义 CORS 配置：

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

添加新服务 returning void 和 null 响应：

[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;
    }
}

调用以上服务：

两种服务 return 204 NoContent 与 CORS Headers:

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
Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
Access-Control-Allow-Headers: Content-Type, Allow, Authorization
Access-Control-Allow-Credentials: true
X-AspNet-Version: 4.0.30319
X-Powered-By: ASP.NET

为什么 ServiceStack 在 HTTP 状态码为 204 No Content 时不添加 CORS headers？

Why does ServiceStack not add the CORS headers when the HTTP status code is 204 No Content?
