1.API

axios(config) 用于直接发送请求

export interface AxiosInstance extends Axios {
  (config: AxiosRequestConfig): AxiosPromise;
}

axios({
  method: 'post',
  url: '/user/12345',
  data: {
    firstName: 'Fred',
    lastName: 'Flintstone'
  }
});

const { default: axios } = require("axios");
const fs = require('fs')
 
axios({
    method: 'get',
    url: 'http://www.baidu.com',
    responseType: 'stream'
}).then(function (response) {
      response.data.pipe(fs.createWriteStream('baidu.html'))
});

重载方法，把 url参数单独提出来

export interface AxiosInstance extends Axios {
  (url: string, config?: AxiosRequestConfig): AxiosPromise;
}

还有以下请求方法
