重写vue-router得push和replace方法

• 解决问题：路由重复导致报错

import Router from "vue-router";
 
const originalPush = Router.prototype.push;
const originalReplace = Router.prototype.replace;
//push
Router.prototype.push = function push(location, onResolve, onReject) {
  if (onResolve || onReject)
    return originalPush.call(this, location, onResolve, onReject);
  return originalPush.call(this, location).catch(err => err);
};
//replace
Router.prototype.replace = function push(location, onResolve, onReject) {
  if (onResolve || onReject)
    return originalReplace.call(this, location, onResolve, onReject);
  return originalReplace.call(this, location).catch(err => err);
