1.不带参数的路由配置 及 跳转
//路由配置：
{
name: "a",
path: "/a",
component: a
}
页面跳转：
this.$router.push('/a');
this.$router.push({path:'/a'});
this.$router.push({name:'a'})
2.带参数的路由配置及页面跳转 和 接收参数
//路由配置：
{
name: "a",
path: "/a/:userid",
component: a
}
//页面跳转：
this.$router.push({name:'a',params:{userid:123}}); 接收: this.$route.params.userid
this.$router.push({path:'/a',params:{userid:123}}) 错误，如果提供了
path，params 会被忽略this.$router.push({path:'/a/123'}); 接收: this.$route.params.userid
this.$router.push({path:'/a?userid=123'}) 接收：this.$route.query.userid ----- 这一项的路由配置 path:'/a' ,不用带参数
this.$router.push({path:'/a',query:{userid:123}}) 接收: this.$route.query.userid ----- 这一项的路由配置 path:'/a' ,不用带参数
