从其他有界上下文验证日期

Question

我有两个边界上下文（学生入学，课程）。 学生注册包括所有学生及其课程ID和作业。 课程具有管理部分，可管理与课程相关的所有信息。 当学生想要获取课程信息时，它会命中一个发送jwt令牌的端点（/ courses / ID）。在课程上下文中，我获得了学生ID，课程ID并创建了在公共汽车上调度的查询。在从课程ID获取课程信息之前，在查询处理程序中，我要验证学生ID是否存在以及该学生是否有此课程。为此，我必须称呼另一种限制学生入学的背景。因此，我一直在寻找如何在互联网上进行处理的过程，结果发现： https://medium.com/@martinezdelariva/authentication-and-authorization-in-ddd-671f7a5596ac

class findByCourseIdAndStudentIdQueryHandler()
    {
        public function handle($findByCourseIdAndStudentIdQuery)
        {
            $courseId = $findByCourseIdAndStudentIdQuery->courseId();
            $studentId = $findByCourseIdAndStudentIdQuery->studentId();

            $student = $this->collaboratorService->studentFrom(
                $courseId,
                $studentId
            );


            $this->courseRepository->findByCourseId($courseId);
        }
    }

    class collaboratorService()
    {
        public function studentFrom($courseId, $studentId)
        {
            $student = $this->studentEnrollmentClient->getStudentFrom($courseId, $studentId);

            if (!$student) {
                throw new InvalidStudentException();
            }

            return $student;
        }
    }

你怎么看？
