uni.previewImageapp端云端打包后打开图片黑屏,本地自定义基座和h5端小程序端正常~
请问如何解决?

<template>  
  <view class="col-img-qrcode">  
    <image @click="imgShow" class="image" :src="qrcode"></image>  
  </view>  
</template>  

<script>  
export default {  
  data() {  
    return {  
      qrcode: '/static/images/qrcode.jpg'  
    };  
  },  
  methods: {  
    imgShow() {  
      uni.previewImage({  
        current: 0,  
        urls: [this.qrcode]  
      });  
    }  
  }  
};
