Node.js之Path模块

Node.js path 模块提供了一些用于处理文件路径的小工具,我们可以通过以下方式引入该模块:

const path = require("path")

方法

1、path.join([path1][, path2][, ...]):

const path = require("path");

console.log(path.join(__dirname + "/index.html" + "/abc" + ".../" + "123")); // G:work
ode
ode1index.htmlabc...123
console.log(path.join(__dirname + "/index.html" + "/abc" + "/.../" + "123")); // G:work
ode
ode1index.htmlabc...123
console.log(path.join(__dirname + "/index.html" + "/abc" + "/../" + "123")); // G:work
ode
ode1index.html123
console.log(path.join(__dirname + "/index.html" + "/abc" + "../" + "123")); // G:work
ode
ode1index.htmlabc..123
console.log(path.join(__dirname + "/index.html" + "/abc" + "/./" + "123")); // G:work
ode
ode1index.htmlabc123
console.log(path.join(__dirname + "/index.html" + "/abc" + "./" + "123")); // G:work
ode
ode1index.htmlabc.123
 

拼接方式:

1)先连接,连接时去掉“”等特殊字符;

2)连接后处理"/../"和"/./"情况。
