一、path模块的引入。
直接引用。node中自带的模块 const path = require('path');二、path.join(path1，path2，path3.......)作用：将路径片段使用特定的分隔符（window：）连接起来形成路径，并规范化生成的路径。若任意一个路径片段类型错误，会报错。 const path = require('path');
let myPath = path.join(__dirname,'/img/so');
let myPath2 = path.join(__dirname,'./img/so');
let myPath3=path.join('/foo', 'bar', 'baz/asdf', 'quux', '..');
console.log(__dirname);
console.log(myPath);
console.log(myPath2);
console.log(myPath3);结果为：E:\test > node main.js E:\test E:\test\img\so E:\test\img\so \foo\bar\baz\asdf 三、path.resolve([from...],to) 作用：把一个路径或路径片段的序列解析为一个绝对路径。相当于执行cd操作。 /被解析为根目录。 let myPath = path.resolve(__dirname,'/img/so');
let myPath2 = path.resolve(__dirname,'./img/so');
let myPath3=path.resolve('/foo/bar', './baz');
let myPath4=path.resolve('/foo/bar', '/tmp/file/');
console.log(__dirname);
console.log(myPath);
console.log(myPath2);
console.log(myPath3);结果为：E:\test > node main.js E:\test E:\img\so E:\test\img\so E:\foo\bar\baz E:\tmp\file参考：https://blog.csdn.net/qq_33745501/article/details/80270708 |
