axios 修改Content-Type设置

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)
 
//如果想传过去的参数是对象就是这用形式
axios.post(url, qs.parse(qs.stringify(params)), {
  headers: {
    'Content-Type': 'application/json;charset=UTF-8'
  },
}).then(res => res.data)
