图片路径写错了，除了完整的文件夹还要有图片格式，例如“/images/001.png”

补充代码

<swiper indicator-dots="{{indicatorDots}}" autoplay="{{autoplay}}"

interval="{{interval}}"

duration="{{duration}}"

>

<book wx:for="{{imgUrls}}">

<swiper-item>

<image src="{{item}}"

class="slide-image"

width="355"

height="150"/>

</swiper-item>

</book>

</swiper>
