axios封装一个通用的请求

import axios from 'axios'
axios.defaults.timeout = 5000

//http request 拦截器
axios.interceptors.request.use(
  config => {
    config.headers = {
      'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8',
      'token': localStorage.getItem('token') // 获取token缓存
    }
    return config
  },
  error => {
    return Promise.reject(error)
  }
);

export default {
  /**
   * 封装get方法
   * @param url
   * @param data
   * @returns {Promise}
   */
  get: function (url, params = {}) {
    return new Promise((resolve, reject) => {
      axios.get(url, {
        params: params
      })
      .then(response => {
        resolve(response.data)
      })
      .catch(err => {
        reject(err)
      })
    })
  },
  /**
   * 封装post请求
   * @param url
   * @param data
   * @returns {Promise}
   */
  post: function (url, data) {
    return new Promise((resolve, reject) => {
      axios.post(url, data)
        .then(response => {
          resolve(response.data)
        }, err => {
          reject(err)
        })
    })
  }
}

使用

vue中
直接导入import http from ‘http.js’

result = http.get(‘地址’, {参数}
