前端vue+element ui文件上传操作。
1、vue项目安装依赖
npm install ali-oss
2、设置OSS支持PUT跨域请求
文件上传公共方法oss.js
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
let OSS = require('ali-oss'); let client = new OSS({ region: 'oss-cn-shanghai', //服务器的地区 accessKeyId: 'xxxxxxxx', accessKeySecret: 'xxxxxxxxxxxx', bucket: 'iweb-web' // OSS文件路径 }); let fileOperation = { putFile (objectUrl, file) { return new Promise((resolve, reject) => { client.put(objectUrl, file).then(res => { if(res.res.status === 200) { resolve(res) } }).catch(err =>{ console.log('文件上传err---',err) }) }) }, } export default fileOperation; |
使用公共方法
imgList.vue
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<el-upload class="upload-demo" action="#" :on-change="getFile" :auto-upload="false" :on-preview="handlePreview" :on-remove="handleRemove" :file-list="fileList" list-type="picture-card" > <el-button size="small" type="primary">点击上传</el-button> </el-upload> |
imgList.js
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 |
import oss from '../../utils/oss.js' export default { data: function() { return { fileList: [{ name: 'food.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100' }, { name: 'food2.jpeg', url: 'https://fuss10.elemecdn.com/3/63/4e7f3a15429bfda99bce42a18cdd1jpeg.jpeg?imageMogr2/thumbnail/360x360/format/webp/quality/100' }] }; }, mounted() { }, methods: { // 上传图片操作 getFile(file) { console.log('file----',file) if (file) { if (!/(\.png|\.gif|\.jpeg|\.jpg)/i.test(file.name)) { this.$message.warning('请上传图片格式文件！'); return; } let date = new Date(); // 保存的文件路径 let objectUrl = "/img/" + date.getFullYear() + "-" + (date.getMonth() + 1) + "/" + file.name; file.raw.url = objectUrl; oss.putFile(objectUrl, file.raw).then(res=>{ if(res.res.status === 200) { this.$message.success('上传成功'); file.url = res.url; this.fileList.push(file) }else { this.$message.error('上传失败'); } }).catch(err=>{ this.$message.error('上传失败err---',err); }) } else { return; } }, // 删除文件 handleRemove(file, fileList) { console.log('1---', file, fileList); }, // 放大查看图片 handlePreview(file) { console.log('2---', file); }, } }; |
注：上传成功可以继续调用nodejs接口将图片分组图片url添加到数据库中操作。
