如何使用递归函数编写多个文件

Question

我想在一次调用中写入文件，但无法循环创建路径。

async function asyncForEach(array, callback) {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array);
}
}

如果我使用条件创建新文件

asyncForEach(items, async (element) => {    
if(element.hasOwnProperty('item')){
const path = 'tests/'+element.name;
console.log(path);
fs.mkdirSync(path, { recursive: true })
// await waitFor(50)
asyncForEach(element.item, async (second) => {
const second_path = path
if(second.hasOwnProperty('item') == false){
// console.log(second.name)
write(second, path, contents)

这是输入的JSON

我想这就是你不想做的，当遇到dir时递归添加路径，当它是叶节点时写入文件，而不知道你的逻辑细节，这是一个演示代码，只是为了说明如何将你的代码转换为递归模型。

请查收，还有问题请留言：

async doFileWriteJob(array, path) {  
for (let index = 0; index < array.length; index++) {
element = array[index]
if(element.hasOwnProperty('item')){
if(!path) {
path = 'tests'
} else {
path = path + '/' + element.name;
}
console.log(path);
if(element.item && element.item.length > 0) {
fs.mkdirSync(path, { recursive: true })
// await waitFor(50)
doFileWriteJob(element.item, path)

} else {
if(element.hasOwnProperty('item') == false){
// console.log(element.name)
write(element, path, element.contents)
}
}
}
}
})
doFileWriteJob(array, '');
