表现如下：
view class='article-list' block wx:for="{{list}}" wx:for-index="idx" wx:key="{{idx}}" wx:for-item="vo" view class='item-box' image src='{{avatar_url}}' mode='aspectFit'/image viewfsfsafasfasf/view view text2019-01-01/text text99次浏览/text /view /view /block /view.item-box { width: 50%; display: flex; flex-direction: column;}.item-box image { width: 100%; vertical-align: center;}翻了下文档，把image标签mode改成widthFix就好使了
