在AuthorizationHandler<T>中获取HTTP请求方法的正确方法是什么？

public class CustomAuthorizationHandler : AuthorizationHandler<CustomRequirement>
{
    protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, CustomRequirement requirement)
    {
        var httpContext = context.Resource as HttpContext;
        if (httpContext != null)
        {
            var httpMethod = httpContext.Request.Method;
            // 进行相应的授权逻辑判断
            // ...
        }

        return Task.CompletedTask;
    }
}
