Path

Path.resolve()

TIP

此方法，在拼装Vue-Router路径时，特别有用

resolve 将路径或路径片段的序列解析为绝对路径。

var path = require("path"); //引入node的path模块

path.resolve("/foo/bar", "./baz"); // returns '/foo/bar/baz'
path.resolve("/foo/bar", "baz"); // returns '/foo/bar/baz'
path.resolve("/foo/bar", "/baz"); // returns '/baz'
path.resolve("/foo/bar", "../baz"); // returns '/foo/baz'
path.resolve("home", "/foo/bar", "../baz"); // returns '/foo/baz'
path.resolve("home", "./foo/bar", "../baz"); // returns '当前工作目录/home/foo/baz'
path.resolve("home", "foo/bar", "../baz"); // returns '当前工作目录/home/foo/baz'

怎么理解呢？上面的操作，其实相当于命令行中的 cd 操作，举例如下：

bash

path.resolve('/foo/bar', '../baz')   # returns '/foo/baz'
# 相当于
cd /foo/bar
cd ..
cd baz
