vite中img标签动态src无法正常显示_vite img src

vite中动态拼接src地址
1.用相对路径的写法在<img>标签上是可以显示的
        <img src="../../assets/rose/rose-1.jpg" alt="" />
2.但是会用动态传值之后，图片显示不了
        <el-image :src="item.src"  />
原因是因为动态地址，路径被加载器解析为字符串，所以图片找不到
解决办法：
（1）import每张图片，使用的时候直接拿去用
       

import rose1 from "../../assets/rose/rose-1.jpg"
import rose2 from "../../assets/rose/rose-2.jpg"
const divArray = reactive([
  {
    id: 1,
    src: rose1 ,
    style_d: "--d:1",
    span_name: "花朵",
    a_name: "五颜六色玫瑰花"
  },
  {
    id: 2,
    src: rose2 ,
    style_d: "--d:2",
    span_name: "花朵",
    a_name: "白色雏菊"
  }
}

但是每张图片都要import，非常笨重
（2）参考vite官方的静态资源处理文档

静态资源处理 | Vite 官方中文文档
使用import.meta.url 是一个 ESM 的原生功能，会暴露当前模块的 URL。将它与原生的 URL 构造器 组合使用，在一个 JavaScript 模块中，通过相对路径我们就能得到一个被完整解析的静态资源

创建一个工具类getImageByPath.ts

/* 将静态资源的图片导入vue中 */
const getImageUrl:any = (name:any) => new URL(`../${name}`, import.meta.url).href
 
export default getImageUrl

组件中使用：

import getImageUrl from "../../utils/getImageByPath"
...
//拼接图片路径
const concatPath = (id: number) => {
  return getImageUrl("assets/rose/rose-" + id + ".jpg")
}
...
const divArray = reactive([
  {
    id: 1,
    src: concatPath(1),
    style_d: "--d:1",
    span_name: "花朵",
    a_name: "五颜六色玫瑰花"
  },
  {
    id: 2,
    src: concatPath(2),
    style_d: "--d:2",
    span_name: "花朵",
    a_name: "白色雏菊"
  }
}
 

完整代码附上：

图片存放的地址不同，concatPath中拼接的url也不同
