Node.js process.cwd() 方法
process.cwd() 方法是process 模块的内置应用程序编程接口,用于获取 node.js 进程的当前工作目录。
句法:
process.cwd()
参数:此方法不接受任何参数。
返回值:该方法返回一个字符串,指定 node.js 进程的当前工作目录。
下面的例子说明了在 Node.js 中process.cwd() 方法的使用:
示例 1:
// Node.js program to demonstrate the
// process.cwd() Method
// Include process module
const process = require('process');
// Printing current directory
console.log("Current working directory: ",
process.cwd());
输出:
Current working directory: C:\nodejs\g\process
示例 2:
// Node.js program to demonstrate the
// process.cwd() Method
// Include process module
const process = require('process');
// Printing current directory
console.log("Current working directory: ",
process.cwd());
try {
// Change working directory
process.chdir('../');
console.log("Working directory after changing"
+ " directory: ", process.cwd());
} catch (err) {
// printing error if occurs
console.error("error occured while changing"
+ " directory: ", err);
}
输出:
Current working directory: C:\nodejs\g\process
Working directory after changing directory: C:\nodejs\g\os
注意:上面的程序将使用node filename.js
命令编译和运行。
