无法使用 FS npm 模块 nodejs 访问网络驱动器上的文件

Question

I have a network drive mapped to X:\\ and for some reason I cannot access the files in it using the FS module. I tried using fs.existsSync(file) and it returns that no files can be found but when I type out the path fs.existsSync('X:\\path\\to\\file') it works fine. Both file and the string I hardcoded are exactly the same, so why is fs returning different results for both? I have to use the "file" variable because I am looping through an array of file paths to create them in my network drive if they do not exist. I have also accounted for the backslashes, and replaced them all with double backslashes so the string is not being escaped.

    //This does not work
    let modifiedfilePathToSiger = path.join('X:\\', filePathToSiger.slice(17));
    let mps = JSON.stringify(modifiedfilePathToSiger)
    //Remove double quotes from mps
    let file = mps.replace(/['"]+/g, '')   //Ex: file here = X:\\Data\\Aerial Photo.docx
    
    let found = fs.existsSync(file);
    console.log(found) //Returns false

    //This does work
    let found = fs.existsSync('X:\\Data\\Aerial Photo.docx');
    console.log(found) //Returns true

One other thing to note, if I type out the whole hardcoded path into fs.existsSync() it works fine and returns true, but if I copy and paste the path that is logged from the console, it returns false, albeit the exact same path... not 1 character is different.

Answer 1

Looks like when I log file variable it returns X:\\Data\\Aerial Photo.docx but when I log the hardcoded string X:\\Data\\Aerial Photo.docx it returns X:\\Data\\Aerial Photo.docx

Make use of .split and path.win32 then path.join

From Node REPL

> path = require('path').win32
<ref *1> {
  resolve: [Function: resolve],
  normalize: [Function: normalize],
  isAbsolute: [Function: isAbsolute],
  join: [Function: join],
  relative: [Function: relative],
  toNamespacedPath: [Function: toNamespacedPath],
  dirname: [Function: dirname],
  basename: [Function: basename],
  extname: [Function: extname],
  format: [Function: bound _format],
  parse: [Function: parse],
  sep: '\\',
  delimiter: ';',
  win32: [Circular *1],
  posix: <ref *2> {
    resolve: [Function: resolve],
    normalize: [Function: normalize],
    isAbsolute: [Function: isAbsolute],
    join: [Function: join],
    relative: [Function: relative],
    toNamespacedPath: [Function: toNamespacedPath],
    dirname: [Function: dirname],
    basename: [Function: basename],
    extname: [Function: extname],
    format: [Function: bound _format],
    parse: [Function: parse],
    sep: '/',
    delimiter: ':',
    win32: [Circular *1],
    posix: [Circular *2],
    _makeLong: [Function: toNamespacedPath]
  },
  _makeLong: [Function: toNamespacedPath]
}
> strArr = file.split('\\')
[ 'X:', 'Data', 'Aerial Photo.docx' ]
> path.join(strArr[0],strArr[1],strArr[2])
'X:\\Data\\Aerial Photo.docx'

it will take care of the slashes respective to environment
