vue获取当前路由的五种方式示例代码

import { defineComponent,ref} from 'vue';
import { useRouter } from 'vue-router';
const router=useRouter
//通过实例化useRouter的router对象中，含有多个属性，其中就包含了当前路由地址，
console.log('router',router.currentRoute.value.fullPath);

import { getCurrentInstance } from 'vue';
const { proxy }: any = getCurrentInstance();
console.log(proxy.$router.currentRoute.value.fullpath);

import {  toRaw} from 'vue';
import { useRouter } from 'vue-router';
let router = useRouter()
console.log(toRaw(router).currentRoute.value.fullPath);
通过toRaw返回其原始对象，即将实例化的router转化为useRouter

import { watch } from 'vue';
import { useRouter } from 'vue-router';
   let router = useRouter()
   watch(router,(newValue, oldValue) => {
        console.log(newValue.currentRoute.value.fullPath);},
      { immediate: true }
    );
 //这一种写法比较麻烦，但是逻辑比较简单，通过监听获取最新的router对象，进而获取路由地址，而且在第一次的时候，就要执行监听，

import {  ref } from 'vue';
import { useRoute } from 'vue-router';
let path=ref("")
const route=useRoute()
path.value=route.path
//这一种最为简单，推荐这种
