nodejs中path模块的用法

path.join([...paths])

Added in: v0.1.16

...paths A sequence of path segments

Returns:

The path.join() method joins all given path segments together using the platform specific separator as a delimiter, then normalizes the resulting path.

Zero-length path segments are ignored. If the joined path string is a zero-length string then'.'will be returned, representing the current working directory.

For example:

path.join('/foo','bar','baz/asdf','quux','..')

// Returns: '/foo/bar/baz/asdf'

path.join('foo',{},'bar')

// throws TypeError: Arguments to path.join must be strings

A TypeError is thrown if any of the path segments is not a string.
