Node.js Path Module
Node.js Path Module
Node.js path module provides a number of small tools for working with file paths, we can be introduced into the module in the following ways:
var path = require("path")
method
| No. | Method & description |
|---|---|
| 1 | path.normalize (p) Standardization route, pay attention to '..' and '.'. |
| 2 | path.join ([path1] [, path2 ] [, ...]) For the connection path. The main purpose of this method is that the current system will correct path separator, Unix systems is "/", Windows systems are "\." |
| 3 | path.resolve ([from ...], to ) The parameterto resolve to an absolute path. |
| 4 | path.isAbsolute (path) Determine whether thepath parameter is an absolute path. |
| 5 | path.relative (from, to) For the relative path into an absolute path. |
| 6 | path.dirname (p) On behalf of the return path of the file folder, similar to the same Unix dirname command. |
| 7 | path.basename (p [, ext]) The last part of the return path. With the Unix command bashname similar. |
| 8 | path.extname (p) Returns the extension part of the file path, the path of the last '' later. If a path does not contain '' or the path contains only one '' and that this '' is the first character of the path, this command returns an empty string. |
| 9 | path.parse (pathString) Returns object path string. |
| 10 | path.format (pathObject) Returns path string from the object, and path.parse contrary. |
Attributes
| No. | Property & Description |
|---|---|
| 1 | path.sep Platform file path delimiter, '\\' or '/'. |
| 2 | path.delimiter Platform separator,; or ':'. |
| 3 | path.posix Provide the above path method, but always posix compatible way interaction. |
| 4 | path.win32 Provide the above path method, but always win32 compatible way interaction. |
Examples
Create main.js file, the code is as follows:
var path = require("path");
// 格式化路径
console.log('normalization : ' + path.normalize('/test/test1//2slashes/1slash/tab/..'));
// 连接路径
console.log('joint path : ' + path.join('/test', 'test1', '2slashes/1slash', 'tab', '..'));
// 转换为绝对路径
console.log('resolve : ' + path.resolve('main.js'));
// 路径中文件的后缀名
console.log('ext name : ' + path.extname('main.js'));
Code execution results are as follows:
$ node main.js normalization : /test/test1/2slashes/1slash joint path : /test/test1/2slashes/1slash resolve : /web/com/1427176256_27423/main.js ext name : .js
