本文实例为大家分享了node+vue实现文件上传的具体代码,供大家参考,具体内容如下
*后端*
const express = require('express'); const router = express.router(); const multer = require('multer'); const fs = require('fs'); const pathlib = require('path'); const videomodel = require('../../models/my_yx_app/video'); //设置 视频文件存放位置 const uploadvido = multer({ dest:'uploads_yx_app/video/' }); //上传视频 router.post('/uploadvideo',uploadvido.single('file'),(req,res)=>{ if (req.file) { let file = req.file; let newname = file.path+pathlib.parse(file.originalname).ext; //修改path fs.rename(file.path,newname,(err)=>{ //修改path if (err) { return res.status(200).json({ code:0, msg:'服务器繁忙!' }) }else { return res.status(200).json({ code:1, msg:'上传完成', title:pathlib.parse(file.originalname).name, videourl:'http://127.0.0.1:3001/uploads_yx_app/video/'+file.filename+pathlib.parse(file.originalname).ext }) } }) }else { return res.status(200).json({ code:0, msg:'服务器繁忙!' }) } });
*前端*
<div class="from-contral" style="position: relative"> <!--此处name 与 uploadvido.single('file') 相同--> <input type="file" name="file" @change="changefile" class="customstyle"> <el-button size="mini" type="primary"> 添加文件 <i class="el-icon-upload el-icon--right"></i> </el-button> <div class="zt-title-video">{{ file.name }}</div> <div class="zt-progress" v-show="percentageshow"> <el-progress :text-inside="true" :stroke-width="20" :percentage="percentage" > </el-progress> </div> </div>
*js处理逻辑数据*
savedata() { //上传 let that = this; let fd = new formdata(); fd.append('file', this.file); fileupdata({ //上传文件存储在后端 method: 'post', url: '/uploadvideo', data: fd, //监听上传时间 //实现进度条 onuploadprogress(progressevent) { that.percentageshow = true; that.percentage = parseint(((progressevent.loaded / progressevent.total) * 100)); } }).then(res => { if (res.data.code === 1) { //数据持久化 fileupdata({ method: 'post', url: '/savevideoinfo', data: { videourl: res.data.videourl, //路径 videoname: res.data.title, //标题 videotype:that.videotype, //类型 username:localstorage.getitem('username') //那个用户上传的 } }).then(res => { if (res.data.code === 1) { settimeout(function () { //为什么延迟,为了使进度条走完 that.$message({ message: '上传成功', type: 'success' }) }, 1000); } }).catch(err => { this.$message.error('服务器繁忙,请稍后重试!'); }); } }).catch(err => { this.$message.error('服务器繁忙,请稍后重试!'); }) },
