How to encapsulate the get and post methods using axios in vue 2.x

import axios from 'axios'
import qs from 'qs'
export class HttpService {
  Get(url, data) {
    return new Promise((resolve, reject) => {
      axios.get(url, {
        params: data
      }).then((res) => {
        if (res) {
          //成功回调
          resolve(res);
        }
      }).catch((error) => {
        reject(error);
      })
    })
  }
  Post(url, data) {
    return new Promise((resolve, reject) => {
      axios.post(url, qs.stringify(data), {
        headers: {
          'Content-Type': 'application/x-www-form-urlencoded',
          'Accept': 'application/json'
        }
      }).then((res) => {
        if (res) {
          //成功回调
          resolve(res);
        }
      }).catch((error) => {
        reject(error);
      })
    })
  }

PostFlie(url, data) {
    return new Promise((resolve, reject) => {
      //根据data对象生成FormData对象
      var temp = new FormData();
      for (var t in data) {
        temp.append(t, data[t]);
      }
      axios.post(url, temp).then((res) => {
        if (res) {
            resolve(res.Data);
        }
      }).catch((error) => {
        reject(error);
      })
    })
  }
