如何构建Vue Axios服务以返回promise树

npm install vue axios

import Vue from 'vue';
import axios from 'axios';

const ApiService = new Vue();
ApiService.$http = axios;

ApiService.request = function(method, url, data) {
  return new Promise((resolve, reject) => {
    this.$http({
      method: method,
      url: url,
      data: data
    })
    .then(response => {
      resolve(response.data);
    })
    .catch(error => {
      reject(error);
    });
  });
};

ApiService.request('GET', '/api/users')
  .then(data => {
    // 处理返回的数据
  })
  .catch(error => {
    // 处理错误
  });
