vue重写路由push方法
/**
重写路由的push方法解决，相同路由跳转时，报错添加，相同路由跳转时，触发watch (仅限string方式传参，形如"view?id=5") */
const routerPush = Router.prototype.push
Router.prototype.push = function push(location) {
if(typeof(location)=="string"){
var Separator = "&";
if(location.indexOf('?')==-1) { Separator='?'; }
location = location + Separator + "random=" + Math.random();
}
return routerPush.call(this, location).catch(error=> error)
}
