Instructions for using the path.resolve method in node.js_node.js

Method description:

Parse the characters at the to parameter into an absolute path.

Grammar:

Copy code The code is as follows:

path.resolve([from ...], to)

Since this method belongs to the path module, the path module needs to be introduced before use (var path= require(“path”) )

Receive parameters:

from source path
to A string that will be parsed to an absolute path

Example:

Copy code The code is as follows:

path.resolve('/foo/bar', './baz')

// returns

'/foo/bar/baz'

path.resolve('/foo/bar', '/tmp/file/')

// returns

'/tmp/file'

path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif')

// if currently in /home/myself/node, it returns

'/home/myself/node/wwwroot/static_files/gif/image.gif'

Another way is to use it as a sequence of cd command shells.

Copy code The code is as follows:

path.resolve('foo/bar', '/tmp/file/', '..', 'a/../subfile')

is similar to:

Copy code The code is as follows:

cd foo/bar
cd /tmp/file/
cd ..
cd a/../subfile
pwd
