const handleChangeType: (data: API.SysResourceEntity_[]) => Array<ITree> = (data) => { let temp: Array<ITree> = []; data.forEach((item) => { if (item.resType === 1) { let p = { title: item.resName, value: item.id, key: item.id, }; if (item.children && item.children.length > 0) { p.children = handleChangeType(item.children); } temp.push(p); } }); return temp; };

这是一个 TypeScript 函数,接收一个 API.SysResourceEntity_[] 类型的参数 data(即一个 SysResourceEntity_ 类型的数组),返回一个 ITree 类型的数组。
该函数的作用是将 SysResourceEntity_ 类型的数据转换成 ITree 类型的树形结构数据。具体实现过程如下:
1. 首先定义一个空数组 temp,用于存储转换后的树形结构数据。
2. 遍历传入的 data 数组,对每个元素进行判断。
3. 如果当前元素的 resType 属性为 1,说明该元素为一级节点,需要将其转换为一个 ITree 对象,同时递归调用 handleChangeType 函数,将该元素的 children 属性转换成 ITree 对象的 children 属性。
4. 将转换后的 ITree 对象 push 到 temp 数组中。
5. 最后返回 temp 数组,即为转换后的树形结构数据。
需要注意的是,该函数中的 ITRee 类型没有给出具体的定义,需要根据实际情况进行定义。另外,该函数中使用了递归调用,因此需要确保传入的数据结构是符合要求的,否则可能会导致递归调用的死循环。

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。
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;
};
