vue页面使用阿里oss上传功能的实例(一)
NNNNNIX 人气:0本文介绍了vue页面使用阿里oss上传功能的实例(一),分享给大家,也给自己留个笔记
直奔主题:
前端部分
1.前端页面中需要引入oss-sdk:
<script src="http://gosspublic.alicdn.com/aliyun-oss-sdk-4.4.4.min.js"></script>
2.自己封装的upload组件:
<template> <div> <div class="oss_file"> <input type="file" :id="id" :multiple="multiple" @change="doUpload"/> </div> </div> </div> </template> <script> export default{ props:{ multiple:{ type: Boolean, twoWay:false }, id:{ type: String, twoWay:false }, url:{ type: Array, twoWay:true } }, data(){ return{ region:'Your oss Region', bucket:'Bucket Name', }; }, methods:{ doUpload(){ const _this = this; Vue.http.get('/alioss/getOssToken').then((result) => { const client = new OSS.Wrapper({ region:_this.region, accessKeyId: result.data.token.AccessKeyId, accessKeySecret: result.data.token.AccessKeySecret, stsToken: result.data.token.SecurityToken, bucket:_this.bucket }) const files = document.getElementById(_this.id); if(files.files){ const fileLen = document.getElementById(_this.id).files const resultUpload = []; for (let i = 0; i < fileLen.length; i++) { const file = fileLen[i]; const storeAs = file.name; client.multipartUpload(storeAs, file, { }).then((results) => { if(results.url){ resultUpload.push(results.url); } }).catch((err) => { console.log(err); }); } _this.url = resultUpload; } }); } } }; </script> <style type="text/css"> .oss_file { height: 100px; width: 100%; } .oss_file input { right: 0; top: 0; opacity: 0; filter: alpha(opacity=0); cursor: pointer; width: 100%; height: 100%; } </style>
3.使用组件:
<template> <div> <div> <ali-upload :url.sync="uploadUrl" :multiple="true" :id="uploadId" :code.sync="uploadCode"></ali-upload> </div> <div v-for="url in uploadUrl"> ![](url) </div> </div> </div> </template> <script> import aliUpload from './../components/aliossupload.vue'; export default{ components:{ aliUpload }, data(){ return{ uploadUrl:[], uploadId:'file', uploadCode:0 }; }, watch:{ uploadCode(val){ console.info(val) } } }; </script>
后端部分
1.首先安装依赖
npm install ali-oss npm install co
2.service文件
'use strict' var OSS = require('ali-oss'); var STS = OSS.STS; var co = require('co'); var sts = new STS({ accessKeyId: 'accessKeyId', accessKeySecret: 'accessKeySecret', }); var rolearn = 'acs:ram::ID:role/ram'; var policy = { "Version": "1", "Statement": [ { "Effect": "Allow", "Action": [ "oss:GetObject", "oss:PutObject" ], "Resource": [ "acs:oss:*:*:Bucket", "acs:oss:*:*:BucketName/*" ] } ] }; class OssUploadService { getOssToken(req, res){ var result = co(function* () { var token = yield sts.assumeRole(rolearn, policy, 15 * 60, 'ossupload'); res.json({ token:token.credentials }) }).catch(function (err) { }); } } module.exports = new OssUploadService()
3.controller文件
'use strict' var ossUploadService = require('../service/ossUploadService') module.exports = function(app) { app.get('/alioss/getOssToken', function(req, res) { const result = ossUploadService.getOssToken(req, res) if (result) { res.json({ code: 100, data: result }) } }) }
到这里就大功告成了吗?错!这只是完成了最基本的部分,接下来我们要在阿里云控制台中设置权限、角色、策略等。
