結論

public class OrderAppService : CrudAppService<Order, OrderDto, Guid>
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public OrderAppService(
        IRepository<Order, Guid> repository,
        IHttpContextAccessor httpContextAccessor)
        : base(repository)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public override async Task<OrderDto> GetAsync(Guid id)
    {
        await CheckGetPolicyAsync();
        return new OrderDto();
    }

    protected override Task CheckGetPolicyAsync()
    {
        var authorization = _httpContextAccessor?.HttpContext?
            .Request.Headers.Authorization.FirstOrDefault();
        if (authorization == "P@ssw0rd")
            return Task.CompletedTask;

        throw new AbpAuthorizationException(code: AbpAuthorizationErrorCodes.
                    GivenPolicyHasNotGrantedWithPolicyName)
            .WithData("Authorization", authorization);
    }
}

原由

內建 CrudAppService 基底類別中定義

Get 方法的輸入參數是 TKey Id

public override async Task<OrderDto> GetAsync(Guid id)

但方法需要額外參數來進行自訂授權驗證

因此打算由 header 傳入驗證用餐數來進行檢查
