這篇文章給大家分享的是有關vue接口請求加密的案例分析的內容。小編覺得挺實用的，因此分享給大家做個參考。一起跟隨小編過來看看吧。
1. 安裝vue項目 npm init webpack project
2 安裝iview npm i iview --save (這里是結合iview框架使用的 可根據自己的需求安裝 當然也可以不安裝)
3 在src目錄下建一個utils文件夾 里面需要放5個js 都是封裝好的js文件 功能不僅僅局限于加密 可以研究一下 你會學到很多東西
1.api.js
/**
* 為vue實例添加http方法
* Vue.use(http)
*/
import http from './http'
export default {
/**
* install鉤子

Vue.prototype.http = http
}
}2. filters.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文件夾下的dev.env.js
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
API_HOST: '"開發環境接口地址"'
})6.頁面中具體使用方法
<template>
<div class="hello">
<Select v-model="model8" clearable >
<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 + "請求路徑",{})
.then(data => {
if (data.code == "success") {
this.cityList = data.data;
this.cityList.splice(0,0,{ productCode: "code", productName: "所有產品" })
}
})
.catch(err => {
console.log(err);
});
}
}
</script>
