wx.previewImage({  current: '',//此处需要http链接图片  urls: [''],//http链接图片数组  success: function (res) { },  fail: function (res) { },  complete: function (res) { },})

二、wxml

<view class='flex-box img-container'>   <view class='flex-item flex-box'>      <image src='{{imgSrcList[0]}}' data-src='{{imgSrcList[0]}}'       mode='aspectFit' bindtap="previeImg"></image>   </view>   <view class='flex-item flex-box'>      <image src='{{imgSrcList[1]}}' data-src='{{imgSrcList[0]}}'       mode='aspectFit' bindtap="previeImg"></image>   </view>   <view class='flex-item flex-box'>      <image src='{{imgSrcList[2]}}' data-src='{{imgSrcList[0]}}'       mode='aspectFit' bindtap="previeImg"></image>   </view> </view>
