I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

1. Use data to transfer parameters

The request method of the frontend is post

Import request from'@ / utils/request'// added bannerexport function saveBanner (data) {return request ({url:'/system/banner/saveBanner', method:'post', data:data})}

Back-end interface reception

/ * Save navigation map * * @ param sysBanner * @ return * / @ PostMapping ("/ saveBanner") public AjaxResult saveBanner (@ RequestBody SysBanner sysBanner) {return sysBannerService.saveBanner (sysBanner);}

2. Use params to transfer parameters

Front-end request

/ / query navigation map list information export function getBannerList (query) {return request ({url:'/ system/banner/list', method: 'get', params: query})}

Back-end reception

The request method is GetMapping when receiving.

And the @ RequestBody annotation is not required for the input parameter.
