微信小程序 和 laravel8 实现搜索后分页 加载

Page({
 
  /**
   * 页面的初始数据
   */
  data: {
    activity:{},
    page:1,
    last_page : 0,
    keyword:''
  },
 
 
//加载
scroll(e){
  let that = this;
  let page = that.data.page+1;
  let keyword = that.data.keyword
  that.setData({
    page:page 
  })
  let last_page = that.data.last_page
  if(page > last_page){
    wx.showToast({
      title: '到底了',
    })
    return ;
  }
  wx.showLoading({
      title: '加载中',
  })
  
  wx.request({
    url: 'http://www.week2.skill.com/api/activity/index',
    data:{page,keyword},
    header: {
      'content-type': 'application/json' // 默认值
    },
    success (res) {
      console.log(res.data)
      let activity = res.data.data.data
      that.setData({
        activity:that.data.activity.concat(activity),
      })
      wx.hideLoading()
    }
  })
},
  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    var that = this;
    wx.request({
      url: 'http://www.week2.skill.com/api/activity/index',
      header: {
        'content-type': 'application/json' // 默认值
      },
      success (res) {
        console.log(res.data)
        let activity = res.data.data.data
        that.setData({
          activity:activity,
          last_page:res.data.data.last_page,
          page:res.data.data.current_page
        })
      }
    })
  },
 
//搜索
  dopost:function(e){
    console.log(e);
    let formData = e.detail.value;
    wx.request({
      url: 'http://www.week2.skill.com/api/activity/index',
      data:formData,
      method:"GET",
      success:res=>{
        console.log(res);
        if(res.data.status==200){
          this.setData({
            activity:res.data.data.data,
            keyword:formData.keyword,
            last_page:res.data.data.last_page,
            page:res.data.data.current_page
          })
        }
      },
      fail(e){
        wx.showToast({
          title: '请求失败',
          icon:"error"
        })
      }
    })
  },
})

控制器：

/**
     * 查询数据 分页展示
     * @param Request $request
     * @return array
     */
    public function index(Request $request)
    {
        $keyword = $request->input('keyword');
        $data = Activity::when($keyword,function ($query,$keyword){
            return $query->where('title','like','%'.$keyword.'%');
        })->select('title','img','surplus_number')->paginate(5);
        return ['status'=>200,'msg'=>'success','data'=>$data];
    }
