使用ServiceStack,我必须有选择地enable authentication服务,通过在相应的类/方法上应用[Authenticate]
属性来请求DTO和操作。
是否可以做反向?即全局启用所有服务/请求的身份验证,然后有选择地禁用某些请求的身份验证(例如,在相关部分使用类似[NoAuthentication]
属性的内容)?
答案 0 :(得分:4)
创建请求过滤器属性,在请求上下文中设置一个标记,表示跳过身份验证:
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
public class NoAuthenticateAttribute : RequestFilterAttribute {
public NoAuthenticateAttribute() : this(ApplyTo.All) {}
public NoAuthenticateAttribute(ApplyTo applyTo) : base(applyTo) {
// execute this before any AuthenticateAttribute executes.
// https://github.com/ServiceStack/ServiceStack/wiki/Order-of-Operations
Priority = this.Priority = ((int) RequestFilterPriority.Authenticate) - 1;
}
public override void Execute(IHttpRequest req, IHttpResponse res, object requestDto)
{
req.Items["SkipAuthentication"] = true;
}
}
创建AuthenticateAttribute
的自定义子类,检查请求中的该标志:
public class MyAuthenticateAttribute : AuthenticateAttribute {
public override void Execute(IHttpRequest req, IHttpResponse res, object requestDto)
{
if (!ShouldSkipAuthenticationFor(req))
base.Execute(req, res, requestDto);
}
private bool ShouldSkipAuthenticationFor(IHttpRequest req)
{
return req.Items.ContainsKey("SkipAuthentication");
}
}
用法:
[MyAuthenticate]
public class MyService : Service
{
public object Get(DtoThatNeedsAuthentication obj)
{
// this will be authenticated
}
[NoAuthenticate]
public object Get(DtoThatShouldNotAuthenticate obj)
{
// this will not be authenticated
}
}
