Java Axios 및 Spring 프론트엔드와 백엔드 분리를 위한 매개변수 전달 사양은 무엇입니까?

@PostMapping("/line")
public List<? extends BaseEntity> commonEChart(@RequestParam String tsCode,
                                     @RequestParam String indexCols,
                                     @RequestParam String table){

return request({
    url: '/chart/line',
    method: 'post',
    params: {   //注意这里的key是params
        tsCode,
        indexCols,
        table
    }
})

let params = new FormData();
params.append('tsCode', tsCode);
params.append('indexCols', indexCols);
params.append('table', table);
return request({
    url: '/chart/line',
    method: 'post',
    data: params   //注意这里的key是data
})

import qs from "qs";

return request({
    url: '/chart/line',
    method: 'post',
    data: qs.stringify({    //注意这里的key是data
        tsCode,
        indexCols,
        table
    })
})

const service = axios.create({
    headers: {
        "Content-Type": "application/x-www-form-urlencoded"
    }
});

@PostMapping("/line")
public List<? extends BaseEntity> commonEChart(@RequestBody DemoModel demo){

return request({
    url: '/chart/line',
    method: 'post',
    data: {    //注意这里的key是data
        tsCode,
        indexCols,
        table
    }
})
