前端文件上传到阿里云OSS存储

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

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

<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

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。
