关于小程序分享后，页面内组件props数据变为null的问题

主页部分代码

<template>  
    <view class="stroe_home">  
        <loginDialog />  
        <float-like-button :storeId="option.shop_id" :num="option.like" />  
        <store-info-bar :option="option" />  
        <main-swiper :swiperHeight="swiperHeight" :imgs="swiperImages" />  
        <view class="stroe_home__content">  
            <store-commodity :storeId="option.shop_id" />  
        </view>  
    </view>  
</template>  
<script>  
data() {  
    return {  
        option: {},  
    }  
},  
onLoad(option) {  
    // 解析传参并赋值  
    this.option = decodeUrl(option)  
},  
</script>

组件代码

<template>  
    <view class="mod_store_info_bar">  
        <view class="mod_store_info_bar__name_and_action">  
            <view class="mod_store_info_bar__name_and_action__name auto_omitted">{{option.shop_name}}</view>  
            <view class="mod_store_info_bar__name_and_action__action">  
                <store-share-button style="margin-right: 10upx;" />  
                <subscription-button :storeId="option.shop_id" />  
            </view>  
        </view>  
        <view class="mod_store_info_bar__info">  
            <view class="mod_store_info_bar__info__address ">  
                <view class="auto_omitted" @tap="toMap">{{option.addr}}</view>  
                <text class="iconfont">&#xe68b;</text>  
            </view>  
            <text>{{option.visits}}人来过</text>  
        </view>  
    </view>  
</template>  
<script>  
props: {  
    option: {  
        type: Object,  
        required: true  
    }  
},  
</script>
