  let arr = [{ name: '小明', id: '1' }, { name: '小李', id: '2' }, { name: '小张', id: '3' }]
      let arr2 = ['1', '2']
      arr2 = arr2.map((i) => {
        const find = arr.filter(j => j.id == i)[0].name
        return {
          userId: i,
          userName: find
        }
      })
        arr2: [{ userName: '小明', userId: '1' },{ userName: '小李', userId: '2' }]
