vue项目中后端传参格式是数组

this.searchinput = window.sessionStorage.getItem('homeinput').replace(/\"/g, "");
this.searchxiala = window.sessionStorage.getItem('homexiala').replace(/\"/g, "");
const res = await this.$http ({
            method: "GET",
            url: '/getpostssearchlist',
            params: {
              _k1: [this.searchinput],
              _aon: this.and,
              _feild: [this.searchxiala],
              refine: this.check,
              from: this.page,
              size: this.pageSize,
            }
           })

因为搜索内容是首页放到sessionstorage里面，搜索页重定向data新数组也不可以。然后误打误撞在传参中加了数组就可以了........
