path.resolve()方法用於將path-segments序列解析為絕對路徑。它通過處理從右到左的路徑順序來工作，在每個路徑之前添加，直到創建絕對路徑為止。生成的路徑被規範化並根據需要刪除了斜杠。如果沒有路徑段作為參數給出，則使用當前工作目錄的絕對路徑。
path.resolve( [...paths] )
參數：該函數接受上麵提到並在下麵描述的一個參數：
- paths:它是一係列文件路徑，可以一起解析以形成絕對路徑。如果此參數不是字符串值，則拋出TypeError。
返回值：它返回帶有絕對路徑的字符串。
以下示例程序旨在說明Node.js中的path.resolve()方法：
範例1：
Node.js
// Node.js program to demonstrate the
// path.resolve() Method
// Import the path module
const path = require('path');
console.log("Current directory:", __dirname);
// Resolving 2 path-segments
// with the current directory
path1 = path.resolve("users/admin", "readme.md");
console.log(path1)
// Resolving 3 path-segments
// with the current directory
path2 = path.resolve("users", "admin", "readme.md");
console.log(path2)
// Treating of the first segment
// as root, ignoring the current directory
path3 = path.resolve("/users/admin", "readme.md");
console.log(path3)輸出：
Current directory:G:\tutorials\nodejs-path-resolve G:\tutorials\nodejs-path-resolve\users\admin\readme.md G:\tutorials\nodejs-path-resolve\users\admin\readme.md G:\users\admin\readme.md
範例2：
Node.js
// Node.js program to demonstrate the
// path.resolve() Method
// Import the path module
const path = require('path');
console.log("Current directory:", __dirname);
// Normalization of the absolute paths
path1 = path.resolve("users", "..", "readme.md");
console.log(path1)
path2 = path.resolve("users", "admin",
"..", "files", "readme.md");
console.log(path2)
path3 = path.resolve("users", "admin",
"..", "files", "..", "readme.md");
console.log(path3)輸出：
Current directory:G:\tutorials\nodejs-path-resolve G:\tutorials\nodejs-path-resolve\readme.md G:\tutorials\nodejs-path-resolve\users\files\readme.md G:\tutorials\nodejs-path-resolve\users\readme.md
