VUE axios请求 封装 get post Http

创建httpService.js 文件

import axios from 'axios';
import { Loading , Message } from 'element-ui';
import { Vuevm } from '../main';
window.Vuevm = Vuevm;
const BASE_URL = process.env.BASE_API; //域名路径

const formatParams = (data)=>{
    let arr = [];
    for (let name in data) {
        arr.push(encodeURIComponent(name) + "=" + encodeURIComponent(data[name]));
    }
    return arr.join("&");
}

axios.defaults.timeout = 15000; //超时时间

export const httpService = (url,params,method,loading=true) => {
    if(loading)
    {
        var loadingInstance = Loading.service({
            lock: true,
            text: '加载中',
            spinner: "el-icon-loading",
            background: "rgba(0, 0, 0, 0.7)"
        });
    }
    
    if(method === 'post')
    {
        return new Promise((resolve, reject) => { 
            axios.post(BASE_URL+url, params,{
                headers: {
                    'Content-Type': 'application/x-www-form-urlencoded'
                }
                }).then(data=>{
                if(loading) loadingInstance.close();
                resolve(data.data);

            }).catch(error=>{
                reject(error);
                Message.error('网络不给力');
                if(loading) loadingInstance.close();
            });
        })
    }
    else
    {
        return new Promise((resolve, reject) => { 
            axios.get(BASE_URL+url+'?'+formatParams(params)).then(data=>{
                resolve(data.data);
                if(loading) loadingInstance.close();
            }).catch(error=>{
                Message.error('网络不给力');
                if(loading) loadingInstance.close();
                reject(error);
            });
        })
    }
}

　　创建 使用的接口API 文件 api.js

import { httpService } from './httpService';

/**
 * @name 医院列表
 * @param {*} params 
 */

export const hospitalList = (params) =>{
    return httpService('hospital/list',params,'get');
}

/**
 * @name 医院详情
 * @param {*} params 
 */

export const hospitalDetail = (params) =>{
    return httpService('/hospital/detail',params,'get');
}

　　页面引用 使用 index.vue

<template>
  <div class="commodit">
    
  </div>
</template>

<script>
import { hospitalList, hospitalDetail } from "@/api/hospital";
export default {
  name: "Commodit",
  components: {

  },
  data() {
    return {
      tableData: [],
    };
  },
  created() {
    this.hospitalList()
  },
  methods: {
    //获取 医院列表
    async hospitalList() {
      var data = { hospitalName: '', pageSize: 10, pageNum: 1 };
      const listData = await hospitalList(data);
            console.log(listData)
      if( listData.code==0 ){
        this.tableData = listData.data.records
      }

    },
  }
};
</script>


<style scoped >
@import "../../filters/css/all.css";

.commodit {

}
</style>
