问题描述
[问题描述:微信小程序转换taro过程中,有wx:key属性没有被转换]

复现步骤
[复现问题的步骤]

  1. taro convert转换微信小程序为taro
  2. taro中出现仍存在wx:key属性

由于代码比较多,只贴出主要部门

// 微信小程序wxml
<popMask id="cancelPop">
    <view slot="before" class="container" wx:if="{{message.length}}">
        <view class="page-section page-section-spacing swiper">
        <swiper
            autoplay="{{autoPlay}}" vertical="{{true}}" circular="{{true}}"
            interval="{{3000}}" next-margin="{{30}}px" bindchange="intervalChange">
            <block wx:for="{{message}}" wx:key="index" >
                <swiper-item catchtouchmove="stopTouchMove">
                    <view class="swiper-item {{index == curIndex ? 'swiper-bac' : ''}} flex v-flex-center"><view class="chart-horn"></view><view class="swiper-left flex1">{{item}}</view></view>
                </swiper-item>
            </block>
        </swiper>
        </view>
    </view>
</popMask>



// 转换后的taro中的JSX部分
    return (
      <Popmask
        id="cancelPop"
        renderBefore={
          <Block>
            <View className="container">
              <View className="page-section page-section-spacing swiper">
                <Swiper
                  autoplay={autoPlay}
                  vertical={true}
                  circular={true}
                  interval={3000}
                  nextMargin={30 + 'px'}
                  onChange={this.intervalChange}
                >
                  <Block>
                    {message.map((item, index) => {
                      return (
                        <Block wx:key="index">
                          <SwiperItem onTouchMove={this.stopTouchMove}>
                            <View
                              className={
                                'swiper-item ' +
                                (index == curIndex ? 'swiper-bac' : '') +
                                ' flex v-flex-center'
                              }
                            >
                              <View className="chart-horn"></View>
                              <View className="swiper-left flex1">{item}</View>
                            </View>
                          </SwiperItem>
                        </Block>
                      )
                    })}
                  </Block>
                </Swiper>
              </View>
            </View>
          </Block>
        }
      >
      </Popmask>
    )

可以看到转换后的JSX还是存在wx:key这个属性

期望行为
[wxml转换成JSX征程]
