saleOutBoundArr.forEach(item => { const saleOutBoundDetailRes = await getSaleOutBoundDetail({ id: item.id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }) console.log("销售出库单详情") })

这是一段 JavaScript 代码，使用了 forEach 方法对 saleOutBoundArr 数组中的每个元素执行一个异步函数。该异步函数调用了 getSaleOutBoundDetail 函数，并传入了两个参数，一个是包含 id 属性的对象，另一个是包含两个 HTTP 请求头的对象。函数执行完毕后，会在控制台输出 "销售出库单详情"。不过需要注意的是，该代码中的 await 关键字只能在 async 函数中使用，否则会报错。

const processSaleBoundArr = async (saleBoundArr, tokenData, accountData) => { let saleOutBounds = []; if (saleBoundArr && saleBoundArr.length) { const customerIds = [...new Set(saleBoundArr.map(item => item.customer_id))]; const customerPromises = customerIds.map(id => { return getCustomerDetail({ id }, { "app-token": tokenData['app-token'], "X-GW-Router-Addr": accountData?.domain }); }); const customerDetails = await Promise.all(customerPromises); saleOutBounds = saleBoundArr.map(saleBound => { const customerDetail = customerDetails.find(detail => detail.data.errcode === 0 && detail.data.data.id === saleBound.customer_id); if (customerDetail) { const customerData = customerDetail.data.data; saleBound.account_open_addr = customerData.account_open_addr; saleBound.addr = customerData.addr; saleBound.bank = customerData.bank; saleBound.bank_account = customerData.bank_account; saleBound.taxpayer_no = customerData.taxpayer_no; saleBound.orgName = customerData.sale_dept_name; saleBound = Object.assign(saleBound, customerData.custom_field); } return saleBound; }); saleOutBounds.sort((a, b) => { if (a.bill_date > b.bill_date) { return -1 } else if (a.bill_date === b.bill_date) { if (a.id < b.id) { return -1 } else if (a.id === b.id) { return 0 } else { return 1 } } else { return 1 } }) } return saleOutBounds; }; 优化这段代码

这段代码可以进行以下优化：

1. 使用对象解构语法简化代码，可以将 tokenData 和 accountData 的属性直接解构出来，方便后面的使用。

2. 使用 Promise.allSettled() 方法替换 Promise.all() 方法，可以在其中使用 try-catch 捕获错误，确保即使其中某一个 Promise 出错也不会影响其他 Promise 的执行。

3. 在 Promise.allSettled() 方法的结果中遍历每一个 Promise 的结果，判断结果是否成功，根据结果来确定是否需要将该元素加入 saleOutBounds 数组。

4. 使用 const 替换 let 声明 saleOutBounds 变量，因为该变量在函数中只被赋值一次，不需要修改。

5. 简化代码逻辑，将排序的回调函数中的相同日期的判断语句改为比较运算符，可以减少代码量，提高可读性。

优化后的代码如下所示：

const processSaleBoundArr = async (saleBoundArr, { "app-token": appToken }, { domain } = {}) => {
  const saleOutBounds = [];

  if (saleBoundArr?.length) {
    const customerIds = [...new Set(saleBoundArr.map(({ customer_id }) => customer_id))];
    const customerPromises = customerIds.map(id => getCustomerDetail({ id }, { "app-token": appToken, "X-GW-Router-Addr": domain }));

    const customerDetails = await Promise.allSettled(customerPromises);

    saleBoundArr.forEach((saleBound, index) => {
      const customerDetail = customerDetails[index].status === 'fulfilled' && customerDetails[index].value.data.errcode === 0 && customerDetails[index].value.data.data.id === saleBound.customer_id;

      if (customerDetail) {
        const { data: customerData } = customerDetails[index].value;

        saleOutBounds.push({
          ...saleBound,
          account_open_addr: customerData.account_open_addr,
          addr: customerData.addr,
          bank: customerData.bank,
          bank_account: customerData.bank_account,
          taxpayer_no: customerData.taxpayer_no,
          orgName: customerData.sale_dept_name,
          ...customerData.custom_field
        });
      }
    });

    saleOutBounds.sort((a, b) => {
      if (a.bill_date > b.bill_date) {
        return -1;
      } else if (a.bill_date === b.bill_date) {
        return a.id - b.id;
      }
      return 1;
    });
  }

  return saleOutBounds;
};

const processSaleBoundArr = async (saleBoundArr, { "app-token": appToken }, { domain } = {}) => { const saleOutBounds = []; if (saleBoundArr?.length) { const customerIds = [...new Set(saleBoundArr.map(({ customer_id }) => customer_id))]; const customerPromises = customerIds.map(id => getCustomerDetail({ id }, { "app-token": appToken, "X-GW-Router-Addr": domain })); const customerDetails = await Promise.allSettled(customerPromises); saleBoundArr.forEach((saleBound, index) => { const customerDetail = customerDetails[index].status === 'fulfilled' && customerDetails[index].value.data.errcode === 0 && customerDetails[index].value.data.data.id === saleBound.customer_id; if (customerDetail) { const { data: customerData } = customerDetails[index].value; saleOutBounds.push({ ...saleBound, account_open_addr: customerData.account_open_addr, addr: customerData.addr, bank: customerData.bank, bank_account: customerData.bank_account, taxpayer_no: customerData.taxpayer_no, orgName: customerData.sale_dept_name, ...customerData.custom_field }); } }); saleOutBounds.sort((a, b) => { if (a.bill_date > b.bill_date) { return -1; } else if (a.bill_date === b.bill_date) { return a.id - b.id; } return 1; }); } return saleOutBounds; }; 捕获异常

在这个函数中，可能会在调用 `getCustomerDetail` 函数时出现错误，也有可能在访问 `customerDetails[index].value` 属性时出现错误。您可以在这两个地方使用 `try-catch` 语句来捕获异常并进行处理。

以下是一个可能的实现方式：

const processSaleBoundArr = async (saleBoundArr, { "app-token": appToken }, { domain } = {}) => {
  const saleOutBounds = [];
  if (saleBoundArr?.length) {
    const customerIds = [...new Set(saleBoundArr.map(({ customer_id }) => customer_id))];
    const customerPromises = customerIds.map(id => getCustomerDetail({ id }, { "app-token": appToken, "X-GW-Router-Addr": domain }));

    try {
      const customerDetails = await Promise.allSettled(customerPromises);
      saleBoundArr.forEach((saleBound, index) => {
        try {
          const customerDetail = customerDetails[index].status === 'fulfilled' && customerDetails[index].value.data.errcode === 0 && customerDetails[index].value.data.data.id === saleBound.customer_id;
          if (customerDetail) {
            const { data: customerData } = customerDetails[index].value;
            saleOutBounds.push({
              ...saleBound,
              account_open_addr: customerData.account_open_addr,
              addr: customerData.addr,
              bank: customerData.bank,
              bank_account: customerData.bank_account,
              taxpayer_no: customerData.taxpayer_no,
              orgName: customerData.sale_dept_name,
              ...customerData.custom_field
            });
          }
        } catch (error) {
          console.error(`Error processing saleBound ${index}:`, error);
        }
      });
      saleOutBounds.sort((a, b) => {
        if (a.bill_date > b.bill_date) {
          return -1;
        } else if (a.bill_date === b.bill_date) {
          return a.id - b.id;
        }
        return 1;
      });
    } catch (error) {
      console.error('Error getting customer details:', error);
    }
  }
  return saleOutBounds;
};

在这个实现中，我们在调用 `Promise.allSettled` 和访问 `customerDetails[index].value` 属性时都使用了 `try-catch` 语句来捕获异常，并在控制台输出错误信息。当发生异常时，程序会跳过当前的 saleBound 并继续处理下一个 saleBound。如果您需要在发生异常时中止程序并返回错误，则可以在 `catch` 语句中抛出一个错误。
