配置动态路由参数id：

routes: [

// 动态路径参数以冒号开头

{ path: '/user/:id', component: User }

]

html路由跳转：

<router-link to="/demo53/8">路径参数跳转</router-link>

①不带参数写法：

<router-link to="home">点我</router-link>

<router-link v-bind:to="'home'">点我</router-link>

<router-link :to="'home'">Home</router-link>

<router-link :to="{ path: 'home' }">Home</router-link>

② 带参数写法：

A：<router-link :to="{ name: 'user', params: { userId: 123 }}">User</router-link>

批注：路由配置格式：

{ path: '/user/:userId', name: 'user', component: User }

导航显示：/user/123

B:<router-link :to="{ path: 'register', query: { plan: 'private' }}">Register</router-link>

批注：带查询参数

导航显示：/register?plan=private

js中使用的方式：

① this.$router.push('xxx') //字符串,这里的字符串是路径path匹配噢，不是router配置里的name

② this.$router.push({ path: 'home' }) //对象

③ this.$router.push({ name: 'user', params: { userId: 123 }}) // 命名的路由这里会变成 /user/123

④ this.$router.push({ path: 'register', query: { plan: 'private' }}) // 带查询参数，变成 /register?plan=private

vue之this.$route.query和this.$route.params接收参数
this.$route.query
A页面传递参数peng=
registerInfoThis.$router.push("/hrhi/psninfo/dynamic/" + data.row.pk_psndoc + '?funcode=60070psninfo&peng=0');
B页面接收参数
created() {
this.penga = this.$route.query["peng"];
},

‘http://localhost:8080/linkParamsQuestion?age=18’

let age = this.$route.query.age; //问号后面参数会被封装进 this.$route.query;

this.$route.params
、router/index.js
{
path:'/mtindex',
component: mtindex,
//添加路由
children:[
{
path:"/detail",
name:'detail',
component:guessdetail
}
] },、传参数（ params相对应的是name query相对应的是path）
this.$router.push({
name: ‘detail’, params:{shopid: item.id}
});、获取参数
this.$route.params.shopid、url的表现形式(url中没带参数)
http://localhost:8080/#/mtindex

.检测路由watch:{
'$route': function (to,from) {
// 对路由变化作出响应...
}
}
或者
watch: {
"$route": "routeChange",
},methods: {
routeChange(){
console.log(this.$route.path);
}}

在 router-view上加上一个唯一的key，来保证路由切换时都会重新渲染触发钩子了

<router-view :key="key"></router-view>computed: {
key() {
return this.$route.name !== undefined? this.$route.name + +new Date(): this.$route + +new Date()
}
}

HttpGet请求拼接url参数

const query = {
client_id: state.auth.clientID,
redirect_uri: location.href,
scope: 'public_repo'
} const queryString = Object.keys(query)
.map(key => `${key}=${encodeURIComponent(query[key] || '')}`)
.join('&') return `http://github.com/login/oauth/authorize?${queryString}`

return vue.$http.get(`https://api.github.com/search/issues?q=${data.keyword}+state:open+repo:${vue.$store.getters.repo}${label}&sort=created&order=desc&page=${data.currentPage}&per_page=${data.pageSize}`, {
headers: {
'Accept': 'application/vnd.github.v3.html'
}
})

url参数转json字符串：

const queryParse = (search = window.location.search) => {
if (!search) {
return {}
} else {
const queryString = search[] === '?' ? search.substring() : search
const query = {}
queryString
.split('&')
.forEach(queryStr => {
const [key, value] = queryStr.split('=')
if (key) {
query[decodeURIComponent(key)] = decodeURIComponent(value)
}
})
return query
}
}const queryStringify = query => {
const queryString = Object.keys(query)
.map(key => `${key}=${encodeURIComponent(query[key] || '')}`)
.join('&')
return queryString
}

获取url参数
//方法封装
function GetRequest() {
    //获取url中"?"符后的字串
    var url = location.search;
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
          var str = url.substr(1);
          strs = str.split("&");
          for(var i = 0; i < strs.length; i ++) {
        theRequest[strs[i].split("=")[0]]=decodeURI(strs[i].split("=")[1]);
          }
    }
    return theRequest;
}
// 方法调用
var Request = new Object();
Request = GetRequest();
var urlCan = Request['参数名'];

方法2：
function getUrlParam(key) {
    // 获取参数
    var url = window.location.search;
    // 正则筛选地址栏
    var reg = new RegExp("(^|&)" + key + "=([^&]*)(&|$)");
    // 匹配目标参数
    var result = url.substr(1).match(reg);
    //返回参数值
    return result ? decodeURIComponent(result[2]) : null;
}
//调用
getUrlParam("参数名");
