path.join()方法用于使用platform-specific定界符连接多个path-segments,以形成单个路径。加入后,最终路径将被规范化。 path-segments使用逗号分隔的值指定。 用法: path.join( [...paths] )参数:该函数接受上面提到并在下面描述的一个参数: paths:它是逗号分隔的一系列路径,这些路径将连接在一起以构成最终路径。返回值:它返回一个带有完整标准化路径的字符串,其中包含所有段。 以下示例说明了Node.js中的path.join()方法: 范例1: Node.js // Node.js program to demonstrate the // path.join() Method // Import the path module const path = require('path'); // Joining 2 path-segments path1 = path.join("users/admin/files", "index.html"); console.log(path1) // Joining 3 path-segments path2 = path.join("users", "geeks/website", "index.html"); console.log(path2) // Joining with zero-length paths path3 = path.join("users", "", "", "index.html"); console.log(path3)输出: users\admin\files\index.html users\geeks\website\index.html users\index.html范例2: Node.js // Node.js program to demonstrate the // path.join() Method // Import the path module const path = require('path'); // Normalizing of the final path path1 = path.join("users", "..", "files", "readme.md"); console.log(path1) // Zero length final path // returns a period (.) path2 = path.join("users", ".."); console.log(path2) // Getting the directory path one folder above console.log("Current Directory:", __dirname); path3 = path.join(__dirname, ".."); console.log("Directory above:", path3)输出: files\readme.md .
