如何从网络系统将.txt文件写入本地地址？

Question

已经在云中运行的Web系统必须将.txt文件写入用户登录时提供的计算机的地址。

const fs = require('fs');
fs.writeFile(
   'C:\Users\user\Documents\'+'nameAchive.txt',  //address provided by the user
                                                 // for example :: C:\Users\user\Documents\
   'data that writes the system',
   error => {
      if (error)
         console.log(error);
      else
         console.log('success');
    }); 

而我得到这个错误错误：ENOENT：没有此类文件或目录，请打开“ C：\ Users \ user \ Documents”

请尝试使用：

const fs = require('fs');

const createDir = (dirPath) => {
  const path = process.cwd() + dirPath;

  fs.mkdir(path, { recurcive: true }, (error) => {
    if (error) {
      console.log('Error!', error);
    } else {
      console.log('Directory created!');
    }
  })
}

const createFile = (filePath, fileContent) => {
  fs.writeFile(filePath, fileContent, (error) => {
    if (error) {
      console.log('Error!', error);
    } else {
      console.log('File created!');
    }
  })
}

createDir('/test_dir');
createFile('./test_dir/newfile.txt', 'ololo');
