效果图：

需安装三个插件：
‘html2canvas’
‘jszip’
‘file-saver’

vue 页面主要代码：

<template>
  <div>
      <div><button type="button"  style="width:120px;height:60px;background:#3388cc;color:#fff;margin-bottom:30px;cursor:pointer;" @click="save()">下载所有图片</button>
 </div>
 <a href="" v-for="(item,index) in serviceImg" :id="'link'+index"></a>
    <div class="course-container" v-for="(item,index) in serviceImg"  :id="'myImage'+index"> 
      <div class="course">
          <img :src="require('./assets/png/'+item)"/>
      </div>
      <div class="code">
          <img src="./assets/logo/logo.png"/>
      </div>
    </div>
  </div>
</template>

   let arr  = require.context("./assets/png", true, /\.png$/).keys();
    this.serviceImg=arr.map(item =>(item.replace('./','')));
    console.log(this.serviceImg);
  },

    methods: {

        let zip = new JSZip();
        let imgs = zip.folder(blogTitle);
        for(let i = 0;i< this.serviceImg.length;i++){
          html2canvas(document.querySelector("#myImage"+i)).then(canvas => {
          let base64 = canvas.toDataURL("image/png");
          imgs.file(this.serviceImg[i],base64.substring(22), {base64: true});
          if( i == this.serviceImg.length-1){

          });
        }
        });
        }
       
      },
     
    }
  }
