vue接口请求加密实例

发布日期： 2026-01-12 阅读量： 作者： 用户投稿

1. 安装vue项目 npm init webpack project

2 安装iview npm i iview --save (这里是结合iview框架使用的可根据自己的需求安装当然也可以不安装)

3 在src目录下建一个utils文件夹里面需要放5个js 都是封装好的js文件功能不仅仅局限于加密可以研究一下你会学到很多东西

1.api.js

/**
 * 为vue实例添加http方法
 * Vue.use(http)
 */
import http from './http'
 
export default {
 /**
 * install钩子
 * @param {Vue} Vue Vue
 */
 install (Vue) {
 Vue.prototype.http = http
 }
}

2. filters.js

// 公共使用的filters
import Vue from 'vue';
import {getTime, getPrdType} from '../utils/time';
 
 
// 区分支付方式的filter
Vue.filter('paywayType', function (value) {
 return value;
});
 
// 时间
Vue.filter('newdate', function (value) {
 return getTime(value);
});
// 时间-分钟
Vue.filter('minute', function (str, n) {
 const num = parseInt(n);
 return str.split(' ')[num];
});
// 分割以：连接多个参数的string
Vue.filter('valStr', function (str, n) {
 const num = parseInt(n);
 return str.split(':')[num];
});
// 根据提供时间计算倒计时
Vue.filter('countDown', function (str) {
 const dateStr = new Date(str).getTime();
 const timeNow = new Date().getTime();
 const countDown = dateStr - timeNow;
 const countDownDay = Math.floor((dateStr - timeNow) / 86400000);// 计算剩余天数
 const countDownHour = Math.floor((dateStr - timeNow) / 3600000 % 24);// 计算剩余小时
 const countDownMin = Math.floor((dateStr - timeNow) / 60000 % 60);// 计算剩余分钟
 // const countDownSec = Math.floor((dateStr - timeNow) / 1000 % 60);// 计算剩余秒
 if (countDown <= 0) {
  return '- - - -';
 } else {
  return countDownDay + '天' + countDownHour + '小时' + countDownMin + '分钟';
 }
});
// 取绝对值
Vue.filter('numberFn', function (numberStr) {
 return Math.abs(numberStr);
});
// 处理图片地址的filter
Vue.filter('imgSrc', function (src) {
 const env = getPrdType();
 switch (env) {
  case 'pre':
   return `https://preres.bldz.com/${src}`;
  case 'pro':
   return `https://res.bldz.com/${src}`;
  case 'test':
  default:
   return `https://testimg.bldz.com/${src}`;
 }
});
// 直接转化剩余时间
Vue.filter('dateShow', function (dateStr) {
 const countDownDay = Math.floor(dateStr / 86400);// 计算剩余天数
 const countDownHour = Math.floor(dateStr / 3600 % 24);// 计算剩余小时
 const countDownMin = Math.floor(dateStr / 60 % 60);// 计算剩余分钟
 // const countDownSec = Math.floor((dateStr - timeNow) / 1000 % 60);// 计算剩余秒
 if (dateStr <= 0) {
  return '- - - -';
 } else if (countDownDay <= 0 && countDownHour <= 0) {
  return countDownMin + '分钟';
 } else if (countDownDay <= 0) {
  return countDownHour + '小时' + countDownMin + '分钟';
 } else {
  return countDownDay + '天' + countDownHour + '小时' + countDownMin + '分钟';
 }
});
// 处理图片
Vue.filter('imgLazy', function (src) {
 return {
  src,
  error: '../static/images/load-failure.png',
  loading: '../static/images/default-picture.png'
 };
});
Vue.filter('imgHandler', function (src) {
 return src.replace(/,jpg/g, '.jpg');
});

3.http.js

import axios from 'axios'
import utils from '../utils/utils'
import {Modal} from 'iview'
// import qs from 'qs';
axios.defaults.timeout = 1000*60
axios.defaults.baseURL = ''

 'Content-Type': 'application/json; charset=utf-8',
 Pragma: 'no-cache',
 'Cache-Control': 'no-cache'
}
// 设置默认头
Object.assign(axios.defaults.headers.common, defaultHeaders)
 
const methods = ['get', 'post', 'put', 'delete']
 
const http = {}
methods.forEach(method => {
 http[method] = axios[method].bind(axios)
})
export default http
export const addRequestInterceptor =
 axios.interceptors.request.use.bind(axios.interceptors.request)
// request前自动添加api配置
addRequestInterceptor(
 (config) => {
 if (utils.getlocal('token')) {
  // 判断是否存在token，如果存在的话，则每个http header都加上token
  config.headers.Authentication = utils.getlocal('token')
 }
 // config.url = `/api${config.url}`
 return config
 },
 (error) => {
 return Promise.reject(error)
 }
)
 
export const addResponseInterceptor =
axios.interceptors.response.use.bind(axios.interceptors.response)
addResponseInterceptor(
 (response) => {
 // 在这里统一前置处理请求响应
 if (Number(response.status) === 200) {
  // 全局notify有问题，还是自己处理吧
  // return Promise.reject(response.data)
  // window.location.href = './'
  // this.$router.push({ path: './' })
 }
 return Promise.resolve(response.data)
 },
 (error) => {
 if (error.response) {
  const title = '温馨提示';
  const content = '<p>登录过期请重新登录</p>'  
  switch (error.response.status) {
  case 401:
   // 返回 401 跳转到登录页面  
   Modal.error({
   title: title,
   content: content,
   onOk: () => {
    localStorage.removeItem("lefthidden")
    localStorage.removeItem("leftlist")
    localStorage.removeItem("token")
    localStorage.removeItem("userInfo")
    localStorage.removeItem("headace")
    localStorage.removeItem("sideleft")
    utils.delCookie("user");
    window.location.href = './'
   }
  })
   break
  }
 }
 return Promise.reject(error || '出错了')
 }
)

5 utils.js

4.配置main.js

import Vue from 'vue'
import App from './App'
import router from './router'
import VueRouter from 'vue-router';
import iView from 'iview';
import 'iview/dist/styles/iview.css'
import http from './utils/http'
import Api from './utils/api'
import utils from './utils/utils'
import './utils/filters'
 
Vue.config.productionTip = false
Vue.use(VueRouter);
Vue.use(iView);
 
Vue.use(http)
Vue.use(Api)
Vue.use(utils)
/* eslint-disable no-new */
 
global.BASE_URL = process.env.API_HOST
 
new Vue({
 el: '#app',
 router,
 components: { App },
 template: '<App/>'
})

5.找到config文件夹下的dev.env.js

module.exports = merge(prodEnv, {
 NODE_ENV: '"development"',
 API_HOST: '"开发环境接口地址"'
})

6.页面中具体使用方法

<template>
 <div class="hello">
  <Select v-model="model8" clearable style="width:200px">
  <Option v-for="item in cityList" :value="item.productCode" :key="item.productCode">{{item.productName }}</Option>
 </Select>
 </div>
</template>
 
<script>
export default {
 name: 'HelloWorld',
 data () {
 return {
  cityList:[],
  model8:"code"
 }
 },
 mounted(){
 this.http
  .post(BASE_URL + "请求路径",{})
  .then(data => {
  if (data.code == "success") {
 this.cityList = data.data;
 this.cityList.splice(0,0,{ productCode: "code", productName: "所有产品" })
  }
  })
  .catch(err => {
  console.log(err);
  });
 }
}
</script>
<style scoped>
</style>
