swiper不显示图片,求解答!

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

autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}" indicator-dots="true">

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

<swiper-item>

<image src="{{item}}" class="slide-image" width="355" height="150"/>

</swiper-item>

</block>

</swiper>

这是index.wxml

const app = getApp()

Page({

data: {

imgUrls: [

'images/swiper01.jpg',

'images/swiper02.png'

],

indicatorDots: false,

autoplay: false,

interval: 5000,

duration: 1000

},

onLoad: function () {

}

})

这是index.js

控制台输出
