后端：

@PostMapping("addChapter")
public R addChapter(@RequestBody EduChapter eduChapter) {
    chapterService.save(eduChapter);
    return  R.ok();
}

//根据章节id查询
@GetMapping("getChapterInfo/{chapterId}")
public R getChapterInfo(@PathVariable String chapterId) {
    EduChapter eduChapter = chapterService.getById(chapterId);
    return R.ok().data("chapter",eduChapter);

}

//修改章节
@PostMapping("updateChapter")
public R updateChapter(@RequestBody EduChapter eduChapter) {
    chapterService.updateById(eduChapter);
    return R.ok();
}

//删除的方法
@DeleteMapping("{chapterId}")
public R deleteChapter(@PathVariable String chapterId) {
    chapterService.removeById(chapterId);
    return R.ok();        
}
