主要是vue3以后，不能通过 params 传递参数，以前路由跳转的时候，通过 params 传递参数很好用，官方建议用pinia

import { defineStore } from 'pinia'

export const useCourseVideoStore = defineStore({
    id: 'toCourseVideo',
    state: () => {
        return {
            courseId:0,
        }
    },
    actions: {
        setCourseId(val){
            this.courseId = val
        }
    },
    getters: {
        getCourseId(){
            return this.courseId
        }
    },
})

//使用
import { useCourseVideoStore } from '~/store/course-video'

const courseVideoStore = useCourseVideoStore()
      courseVideoStore.setCourseId(this.$route.params.id)
      
const courseVideoStore = useCourseVideoStore()
    let courseId  = courseVideoStore.getCourseId
