【说明】
该工具类的作用是，给定一个图片的url地址，计算出图片的高宽比，计算高宽比的作用是让图片可以按照正常比例显示

因为首页已经查询到商品的很多信息了，点击查看商品详情的时候，很多信息不需要再查询一遍了，可以直接将商品的已知信息通过路由传递到新的页面去，需要注意的时候，将对象作为参数传递之前，需要先将对象进行编码
uni.navigateTo({
url: "/pages/product/detail?productVo=" + encodeURIComponent(JSON.stringify(productVo))
})
首先将查询到的商品分为两组
let productVoList = res.rows;
this.productList = [
[],
[]
];
for (var i = 0; i < productVoList.length; i++) {
if (i % 2 == 0) {
// 第一列数据
this.productList[0].push(productVoList[i]);
} else {
// 第二列数据
this.productList[1].push(productVoList[i]);
}
}
然后在布局中使用行列布局即可，即使用一行两列的方式来显示商品信息
// 给文字添加中划线
text-decoration: line-through;
/**
* 查询商品Vo列表
*/
@PreAuthorize("@ss.hasPermi('market:product:list')")
@PostMapping("/listProductVo")
@ApiOperation("获取商品列表")
public TableDataInfo listProductVo(@RequestBody ProductVo productVo) {
startPage();
if (productVo.getProductCategoryId() != null) {
// --if-- 当分类不为空的时候，只按照分类来搜索
productVo.setKeyword(null);
}
List<ProductVo> list = productService.selectProductVoList(productVo);
return getDataTable(list);
}
/**

*
* @param productVo
* @return
*/
@Override
public List<ProductVo> selectProductVoList(ProductVo productVo) {
// List<ProductVo> productVoList = new ArrayList<>();
List<ProductVo> productVoList = baseMapper.selectProductVoList(productVo);
///设置每个商品的图片
// 获取所有商品的id
List<Long> productIdList = productVoList.stream().map(item -> {
return item.getId();
}).collect(Collectors.toList());
// 查询出所有商品的图片
if (productIdList.size() > 0) {
List<Picture> pictureList = pictureService.selectPictureListByItemIdListAndType(productIdList, PictureType.PRODUCT.getType());

itemIdAndPicList.put(picture.getItemId(), picList);
} else {

}
}
// 给每个商品设置图片
