uniapp实现轮播中间大两头小

这个效果我搞了整整两天时间，这个事情是uniapp的current和active-class使用时好像没有变化，不知道是它们有问题还是我使用的不对。

直接贴代码
下面展示一些 内联代码片。

html

<swiper class="swiper-block" :indicator-dots="true" :autoplay="true" :interval="3000" :duration="1000" circular='true' previous-margin='90rpx' next-margin='90rpx' current='0' @change="swiperChange">
				<swiper-item class="swiper-item" v-for="(item,index) in swiperImgUrls">
					<image :src="item" :class="['slide-image', currentIndex === index?'active':'']" mode="aspectFill"></image>
				</swiper-item>
</swiper>
