优化这段代码” data: { goodsObj: {}, goods_id: null}, onLoad({ goods_id }) { console.log(goods_id); this.setData({ goods_id }); this.getGoodsDetail(); }, async getGoodsDetail() { try { const { goods_id } = this.data; const [goodsObj] = await Promise.allSettled([ request({ url: "/goods/detail", data: { goods_id } }) ]); if (goodsObj.status === "fulfilled") { console.log(goodsObj.value); this.setData({ goodsObj: goodsObj.value }); this.setData({ goodsObj: { goods_name: goodsObj.value.goods_name, goods_price: goodsObj.value.goods_price, goods_introduct: goodsObj.value.goods_introduct.replace(/\.webp/g,'.jpg'), pics: goodsObj.value.pics } }); } else { throw new Error(goodsObj.reason); } } catch (error) { console.error(error); // 处理错误的方式，例如提示用户网络异常等信息 }}, handlePreviewImage(){ // console.log("预览"); const urls = this.GoodsInfo.pics.map(v=>v.pics_mid); wx.previewImage({ current:urls[0], urls: urls, }) } })“

可以优化的地方如下：

1. 使用async/await异步请求数据，可以避免回调地狱和提高代码可读性；

2. 使用try/catch捕获异步请求时的错误，提高代码的健壮性；

3. 对获取到的商品详情进行处理，只保留需要用到的字段，避免不必要的数据传输和占用存储空间。

4. 在setData时，可以将需要修改的属性整合成一个对象一次性进行修改，避免多次setData。

优化后的代码如下：

data: {
  goodsObj: {},
  goods_id: null
},
onLoad({ goods_id }) {
  console.log(goods_id);
  this.setData({ goods_id });
  this.getGoodsDetail();
},
async getGoodsDetail() {
  try {
    const { goods_id } = this.data;
    const [goodsObj] = await Promise.allSettled([
      request({ url: "/goods/detail", data: { goods_id } })
    ]);
    if (goodsObj.status === "fulfilled") {
      console.log(goodsObj.value);
      const goodsData = goodsObj.value;
      const newData = {
        goods_name: goodsData.goods_name,
        goods_price: goodsData.goods_price,
        goods_introduct: goodsData.goods_introduct.replace(/\.webp/g,'.jpg'),
        pics: goodsData.pics
      };
      this.setData({ goodsObj: newData });
    } else {
      throw new Error(goodsObj.reason);
    }
  } catch (error) {
    console.error(error);
    // 处理错误的方式，例如提示用户网络异常等信息
  }
},
handlePreviewImage() {
  const { pics } = this.data.goodsObj;
  const urls = pics.map(v => v.pics_mid);
  wx.previewImage({
    current: urls[0],
    urls: urls,
  });
}
