1、qs.js库说明
qs是一个url参数转化（parse和stringify）的js库。
https://www.npmjs.com/package/qs
2、使用（以vue文件做示例）
（1）基本语法
<template> ???<div> ???????qs.js ???</div></template><script> ???import qs from ‘qs‘ ???import _ from ‘lodash‘ ???export default { ???????components: {}, ???????methods: { ???????????qs() { ???????????????var obj = qs.parse(‘a=b&c=d‘); ???????????????//输出true ???????????????console.log(_.isEqual(obj, { ???????????????????a: ‘b‘, ???????????????????c: ‘d‘ ???????????????})) ???????????????var str = qs.stringify(obj); ???????????????//输出true ???????????????console.log(_.isEqual(str, ‘a=b&c=d‘)); ???????????} ???????}, ???????mounted() { ???????????this.qs(); ???????} ???};</script><style scoped></style>（2）忽略符号?
<template><div>qs.js</div></template><script>import qs from ‘qs‘import _ from ‘lodash‘export default {components: {},methods: {qs() {//忽略前面的？var obj = qs.parse(‘?a=b&c=d‘, { ignoreQueryPrefix: true });//输出trueconsole.log(_.isEqual(obj, {a: ‘b‘,c: ‘d‘}))var str = qs.stringify(obj);//输出trueconsole.log(_.isEqual(str, ‘a=b&c=d‘));}},mounted() {this.qs();}};</script><style scoped></style>（3）stringify方法编码
<template><div>qs.js</div></template><script>import qs from ‘qs‘import _ from ‘lodash‘export default {components: {},methods: {qs() {//输出a[b]=cconsole.log(qs.stringify({a: {b: ‘c‘}}, {encode: false}))}},mounted() {this.qs();}};</script><style scoped></style>（4）qs 处理数组
<template><div>qs.js</div></template><script>import qs from ‘qs‘import _ from ‘lodash‘export default {components: {},methods: {qs() {//输出 ‘a%5B0%5D=b&a%5B1%5D=c&a%5B2%5D=d‘console.log(qs.stringify({a: [‘b‘, ‘c‘, ‘d‘]}))//输出 a[0]=b&a[1]=c&a[2]=dconsole.log(qs.stringify({a: [‘b‘, ‘c‘, ‘d‘]}, {encode: false}))//输出 ‘a=b&a=c&a=d‘console.log(qs.stringify({a: [‘b‘, ‘c‘, ‘d‘]}, {indices: false}))}},mounted() {this.qs();}};</script><style scoped></style>qs.js库 使用方法
