axios 修改Content-Type設置

import axios from 'axios';
import qs from 'querystring';

axios.post(url, qs.stringify(params), {
  headers: {
    'Content-Type': 'application/json;charset=UTF-8'
  },
}).then(res => res.data)
 
//如果想傳過去的參數是對象就是這用形式
axios.post(url, qs.parse(qs.stringify(params)), {
  headers: {
    'Content-Type': 'application/json;charset=UTF-8'
  },
}).then(res => res.data)
