若依 this.$router.push 同地址不同参，页面不刷新问题

beforeRouteLeave (to, from, next) {
  debugger;
    if (to.name === 'Cgsqmx' && sessionStorage.getItem("cgsqmx")==="Refresh") {
      try {
        var cache = this.$vnode.parent.componentInstance.cache;
        var key="";
        for(var prop in cache){
          if(prop.lastIndexOf("cgsqmx")>0){
            key=prop;
          }
        }
        if(key!=""){
          delete cache[key];
        }
      } catch (error) {
      }
      // // console.log('返回管理页面')
      // if (this.$vnode && this.$vnode.data.keepAlive) {
      //   if (this.$vnode.parent && this.$vnode.parent.componentInstance && this.$vnode.parent.componentInstance.cache) {
      //     if (this.$vnode.componentOptions) {
      //       var key = this.$vnode.key == null
      //         ? this.$vnode.componentOptions.Ctor.cid + (this.$vnode.componentOptions.tag ? `::${this.$vnode.componentOptions.tag}` : '')
      //         : this.$vnode.key
      //       var cache = this.$vnode.parent.componentInstance.cache
      //       var keys = this.$vnode.parent.componentInstance.keys
      //       if (cache[key]) {
      //         if (keys.length) {
