vue中传参params和data的区别

import request from '@/utils/request'

// 新增banner
export function saveBanner(data){
  return request({
    url:'/system/banner/saveBanner',
    method:'post',
    data:data
  })
}

@PostMapping("/saveBanner")
public ajaxResult saveBanner(@RequestBody SysBanner sysBanner) {
	return sysBannerService.saveBanner(sysBanner);
}

//查询导航图列表信息
export function getBannerList(query){
  return request({
    url: '/system/banner/list',
    method: 'get',
    params: query
  })
}
