一，安装xmp-js:

1,xmp-js在npm的地址:

2,安装

liuhongdi@lhdpc:/data/vue/imgtouch$ npm i --save xmp-js
 
added 1 package in 3s

3,查看安装的版本:

二，js代码 ：

<template>
  <div>
    <img v-if="imgSrc.length > 0" id="fg" :src="imgSrc" style="300px;" />
    <br/>
    选择图片读取xmp信息:
    <input type="file" ref="hiddenfile" accept="image/*" @change="readXmp" class="hiddenInput" />
    <div v-if="isXmp == 1">
      <div v-for="(item, index) in tags " :key="index" style="display: flex;text-align: left;">
        <div style="200px; ">{{ index }}:</div>
        <div style="600px; ">
          {{ item }}
        </div>
      </div>
    </div>
    <div v-if="isXmp == 0">
      图片无xmp信息可读取
    </div>
  </div>
</template>
<script>
import XMP from "xmp-js";
import {ref} from "vue"
export default {
  name: "IptcImg",
  setup() {
    //exif tags
    const tags = ref({});
    //当前图片是否存在xmp
    const isXmp = ref(-1);
    //图片的src
    const imgSrc = ref("");
    //读取xmp
    const readXmp = (e) => {
      let file = e.target.files[0];
      let reader = new FileReader();
      reader.readAsDataURL(file);
      reader.onload = e =>{
          //显示图片
        imgSrc.value = reader.result;
          //读取xmp
          let xmp = new XMP(e.target.result);
          let   raw = xmp.find();
          console.log(raw);
          let   parsed = xmp.parse();
          console.log(parsed);
 
        tags.value = parsed;
        if (Object.getOwnPropertyNames(tags.value).length >0) {
          isXmp.value = 1;
        } else {
          isXmp.value = 0;
        }
      }
    }
 
    return {
      readXmp,
      tags,
      isXmp,
      imgSrc,
    }
  }
}
</script>
 
<style scoped>
</style>

三，测试效果

有xmp数据时

无xmp数据可读取时

四，查看vue框架的版本:
