Node.js fs.readlinkSync()方法
原文:https://www . geesforgeks . org/node-js-fs-readlinksync-method/
fs.readlinkSync()方法是 fs 模块的内置应用编程接口，用于同步返回符号链接的值，即链接到的路径。可选参数可用于指定链接路径的字符编码。
语法:
fs.readlinkSync( path, options )
参数:该方法接受两个参数，如上所述，如下所述:
- Path: It is a String, Buffer or URL that represents the path of symbolic link.
- Option: It is an object or string that can be used to specify optional parameters that will affect the output. It has an optional parameter:
- Code: It is a string value that specifies the character code of the return link path. The default value is utf8.
下面的例子说明了 Node.js 中的 fs.readlinkSync()方法:
例 1:
// Node.js program to demonstrate the
// fs.readlinkSync() method
// Import the filesystem module
const fs = require('fs');
// Create a symbolic link
fs.symlinkSync(__dirname + "\\example_file.txt",
"symlinkToFile", 'file');
console.log("\nSymlink created\n");
// Get the path of the symbolic link
symlinkPath = fs.readlinkSync("symlinkToFile");
console.log("Path of the symlink:", symlinkPath);
输出:
Symlink created
Path of the symlink: G:\tutorials\nodejs-fs-readlinkSync\example_file.txt
示例 2: 本示例创建一个指向目录的符号链接。
// Node.js program to demonstrate the
// fs.readlinkSync() method
// Import the filesystem module
const fs = require('fs');
// Create a symbolic link
fs.symlinkSync(__dirname +
"\\example_directory", "symlinkToDir", 'dir');
console.log("\nSymlink created\n");
// Get the path of the symbolic link
symlinkPath = fs.readlinkSync("symlinkToDir");
console.log("Path of the symlink:", symlinkPath);
输出:
Symlink created
Path of the symlink: G:\tutorials\nodejs-fs-readlinkSync\example_directory
