(精华)2020年7月16日 JavaScript 插件 path-to-regexp解析url 的正则表达式

var pathToRegexp = require('path-to-regexp')

var re = pathToRegexp('/foo/:bar')
console.log(re);///^\/foo\/((?:[^\/]+?))(?:\/(?=$))?$/i
var pathToRegexp = require('path-to-regexp')

var re = pathToRegexp('/foo/:bar');     // 匹配规则
var match1 = re.exec('/test/route');    // url 路径
var match2 = re.exec('/foo/route');     // url 路径

console.log(match1);//null
console.log(match2);//[ '/foo/route', 'route', index: 0, input: '/foo/route' ]
var pathToRegexp = require('path-to-regexp');

var url = '/user/:id';
console.log(pathToRegexp.parse(url));

var pathToRegexp = require('path-to-regexp')

var url = '/user/:id/:name'
var data = {id: 10001, name: 'bob'}
console.log(pathToRegexp.compile(url)(data))//user/10001/bob
