将相对路径转换为绝对路径

In my File-system my working directory is here:

在我的文件系统中，我的工作目录在这里:

C:\temp\a\b\c\d

C:\ temp \ \ b \ C \ d

and under b\bb there's file: tmp.txt

在b\bb下有一个文件:tmp.txt

C:\temp\a\b\bb\tmp.txt

C:\ temp \ \ b \ bb \ tmp.txt

If I want to go to this file from my working directory, I'll use this path:

如果我想从我的工作目录到这个文件，我将使用这条路径:

"../../bb/tmp.txt"

In case the file is not exist I want to log the full path and tell the user:
"The file C:\temp\a\b\bb\tmp.txt is not exist".

如果文件不存在，我想记录完整的路径并告诉用户:“文件C:\temp\a\b\b \bb\tmp”。三是不存在的”。

My question:

我的问题:

I need some function that convert the relative path: "../../bb/tmp.txt" to absolute: "C:\temp\a\b\bb\tmp.txt"

我需要一些函数来转换相对路径:../../bb/tmp。txt”绝对:“C:\ temp \ \ b \ bb \ tmp.txt”

In my code it should be like this:

在我的代码中应该是这样的:

console.log("The file" + convertToAbs("../../bb/tmp.txt") + " is not exist")

2 个解决方案

#1

Use path.resolve

使用path.resolve

try:

试一试:

resolve = require('path').resolve
resolve('../../bb/tmp.txt')

#2

You could also use __dirname and __filename for absolute path.

您还可以使用__dirname和__filename作为绝对路径。
