1-准备工作

确认安装node和npm

安装 qiniu,formidable,express模块

npm install --save qiniu formidable

[x] 导入模块

let qiniu = require('qiniu'), formidable = require('formidable'), express = require('express'), router = express.Router();

2-服务器端的云存储操作

2-1文件上传

router.post('/qiniu', function (req, res, next) { let bucket = 'myblog', key = '', form = formidable.IncomingForm(), token, putPolicy; form.uploadDir = path.join(__dirname, '../../', 'public/img/upload'); form.keepExtensions = true form.parse(req, function (err, fields, files) { if (err) { console.log(err); } key = files.mypic.path.split(path.sep).pop(); putPolicy = new qiniu.rs.PutPolicy(bucket + ':' + key) //设置回调 // putPolicy.callbackUrl = 'http://localhost:81/test/callback' // putPolicy.callbackBody = 'filename=$(fname)&filesize=$(fsize)' token = putPolicy.token() console.log('token', token) let extra = new qiniu.io.PutExtra() qiniu.io.putFile(token, key, files.mypic.path, extra, function (err, ret) { if (err) { console.log(err) } console.log('ret', ret); res.json({ token: token, ret: ret, files: files, fields: fields }) }) })})

文件下载

router.get('/download/:key', function (req, res, next) { let url = 'http://xxxx.bkt.clouddn.com/' + req.params.key, policy = new qiniu.rs.GetPolicy(); console.log(url); res.json({url: policy.makeRequest(url)})})

文件获取

router.get('/info/:key', function (req, res, next) { let bucket = 'myblog', key = req.params.key, client = new qiniu.rs.Client(); client.stat(bucket, key, (err, ret) => { if (err) { console.log(err); } res.json(ret); })})
