~~~
	問題描述： 后臺返回了圖片路徑，但是數據庫中，并沒有圖片資源。畢竟是使用了第三方的存儲
~~~

解決方案： 

   使用img標簽的onerror屬性。
   
   

例子： 
~~~
// 直接加載
<img src="../../assets/img/timg.jpg">
// 設置為logo.png加載失敗后顯示的默認圖片
<img src="/logo.png" onerror="this.src=../../assets/img/timg.jpg">
~~~

* webpack改變圖片的路徑


~~~
<img src="/logo.png" :onerror="defaultImg">

data() {
  return {
    defaultImg: 'this.src="' + require('../../assets/img/timg.jpg') + '"'
  }
}
~~~
