Axios安装封装api接口

官方文档地址axios 安装axios

npm install axios

在main.js中添加

import Axios from 'axios'
Vue.prototype.$axios = Axios;

new Vue({
  el: '#app',
  Axios,
  components: { App },
  template: '<App/>'
})

在src中新建一个axios文件夹，建一个http.js文件 Dialog为vant组件

import axios from "axios";
import qs from "qs";
import {
  Dialog
} from "vant";

// 读取环境配置获取接口地址
axios.defaults.baseURL = process.env.VUE_APP_BASE_URL;

//post请求头
axios.defaults.headers.post["Content-Type"] =
  "application/x-www-form-urlencoded;charset=UTF-8";
//设置超时
axios.defaults.timeout = 10000;

axios.interceptors.request.use(
  config => {
    return config;
  },
  error => {
    return Promise.reject(error);
  }
);

axios.interceptors.response.use(
  response => {
    if (response.status == 200) {
      return Promise.resolve(response);
    } else {
      return Promise.reject(response);
    }
  },
  error => {
    Dialog.alert({
      title: '提示',
      message: '网络请求失败，请刷新重试',
    })
  }
);

export default {
  post(url, data) {
    return new Promise((resolve, reject) => {
      axios({
          method: 'post',
          url,
          data: qs.stringify(data),
        })
        .then(res => {
          resolve(res.data)
        })
        .catch(err => {
          reject(err)
        });
    })
  },

  get(url, data) {
    return new Promise((resolve, reject) => {
      axios({
          method: 'get',
          url,
          params: data,
        })
        .then(res => {
          resolve(res.data)
        })
        .catch(err => {
          reject(err)
        })
    })
  }
};

在main.js中引入

import https from './axios/http'
Vue.prototype.https = https

新建个request.js文件用来放全部接口

import http from './http'

//Object.assign拷贝每个接口固定传参
const post = (url, data) => http.post(url, Object.assign({
  api_key: "133132",
  sign: "133132"
}, data))


/**
 * 传一个参数的
 * @param {*}
 */
const getClassSchedule = (schedule_id) => post('getClassSchedule', {
  schedule_id,
})

/**
 * 传多个参数的
 * @param {*}
 * page:1
 * limit:10 最大页数
 */
const getCarouselList = ({
  page,
  limit
}) => post('getCarouselList', {
  page,
  limit,
})

/***
 * 不传参数的
 * @param {*}
 */
const getUserInfo = () => post('getUserInfo', {})

//接口导出
export {
getClassSchedule,
getCarouselList,
getUserInfo 
}

在组件中调用

//导入接口
import { getClassSchedule ,getCarouselList,} from "../axios/request";
export default {

  methods: {
  	//传一个值的
	async getmore() {
     const res = await getClassSchedule(id);
      if (res.status == 1) {
      } else {
      }
    },
	//传多个值的
	async getbanner() {
      const res = await getCarouselList({ page: 1, limit: 10 });
      if (res.status == 1) {
      } else {
      }
    }
	//不传值的
	async getinfo() {
      const res = await getUserInfo();
      if (res.status == 1) {
      } else {
      }
   },
	}
}
