const processSaleOutBoundDetailArr = async (saleOutBoundArr, tokenData, accountData) => { let saleOutBoundDetailArr = [] if (saleOutBoundArr?.length > 0) { for (const item of saleOutBoundArr) { const saleOutBoundDetailRes = await getSaleOutBoundDetail( { id: item.id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain } ); if (saleOutBoundDetailRes.data.errcode === 0) { item.detailList = await processMaterial(item.id, saleOutBoundDetailRes.data.data.material_entity, tokenData, accountData) } saleOutBoundDetailArr.push(item) } } return saleOutBoundDetailArr } const processMaterial = async (orderId, materials, tokenData, accountData) => { let materialArr = [] if (materials && materials.length) { const materialIds = [...new Set(materials.map(item => item.material_id))]; const materialPromises = materialIds.map(id => { return getMaterialDetail({ id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }); }); const materialDetails = await Promise.all(materialPromises); materialArr = materials.map(material => { const materialDetail = materialDetails.find(detail => detail.data.errcode === 0 && detail.data.data.id === material.material_id); if (materialDetail) { const meterailData = materialDetail.data.data; material.model = meterailData.model material.fetch_category_id = meterailData.fetch_category_id material.tax_rate = meterailData.tax_rate material.orderId = meterailData.orderId } return material; }); } return materialArr; }; 优化这段代码

这段代码可以优化的地方有：

1. 使用`for...of`循环代替`for`循环，可以使代码更加简洁易读。

2. 使用`Promise.allSettled`代替`Promise.all`，可以避免其中一个Promise被reject而导致整个Promise.all被reject的情况。

3. 将多次调用的相同参数的请求合并为一个请求，可以减少网络请求的次数，提高性能。

4. 使用可选链(?.)和空值合并运算符(??)可以更好地处理可能为空的变量，避免出现错误。

优化后的代码如下：

const processSaleOutBoundDetailArr = async (saleOutBoundArr, tokenData, accountData) => {
  const saleOutBoundDetailArr = [];
  if (saleOutBoundArr?.length > 0) {
    for (const item of saleOutBoundArr) {
      const saleOutBoundDetailRes = await getSaleOutBoundDetail(
        { id: item.id },
        { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }
      );
      if (saleOutBoundDetailRes?.data?.errcode === 0) {
        item.detailList = await processMaterial(item.id, saleOutBoundDetailRes.data.data.material_entity, tokenData, accountData);
      }
      saleOutBoundDetailArr.push(item);
    }
  }
  return saleOutBoundDetailArr;
};

const processMaterial = async (orderId, materials, tokenData, accountData) => {
  if (!materials?.length) {
    return [];
  }
  const materialIds = [...new Set(materials.map(item => item.material_id))];
  const materialPromises = materialIds.map(id => {
    return getMaterialDetail({ id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain });
  });
  const materialDetails = await Promise.allSettled(materialPromises);
  const materialArr = materials.map(material => {
    const materialDetail = materialDetails.find(detail => detail.status === "fulfilled" && detail.value?.data?.errcode === 0 && detail.value?.data?.data?.id === material.material_id)?.value;
    if (materialDetail) {
      const meterailData = materialDetail.data.data;
      material.model = meterailData.model;
      material.fetch_category_id = meterailData.fetch_category_id;
      material.tax_rate = meterailData.tax_rate;
      material.orderId = meterailData.orderId;
    }
    return material;
  });
  return materialArr;
};
