首先需要弄一个阿里云存储。然后配置一下。前端就可以直接上传图片并回显。
可在父级组件定义上传图片类型以及大小。默认为500kb。样式可以自适应调整。
<template> <div class="upLoat"> <a href="javascript:;" class="file">上传图片 <input type="file" :accept="typeArr" @change="upload($event)"> </a> </div> </template> <script> import {Toast} from ‘mint-ui‘; export default { props : [‘data‘, ‘typeArr‘, ‘size‘], data(){ return { client : ‘‘, fileSize: 500000 } }, created(){ if (this.size) { this.fileSize = this.size; } this.client = new OSS.Wrapper({ region : process.env.region, secure : true, accessKeyId : process.env.accessKeyId, /*这两者到阿里云控制台获得*/ accessKeySecret: process.env.accessKeySecret, bucket : process.env.bucket /*装图片的桶名*/ }); }, methods: { /**上传图片**/ upload(event){ var self = this; var file = event.target.files[0]; var type = file.name.split(‘.‘)[1]; var storeAs = this.getUuid() + ‘.‘ + type; var boolean = true; if (file.size > this.fileSize) { Toast(‘亲,图片不能超过!‘ + this.fileSize / 1000 + ‘kb‘); return false; } if (this.typeArr && this.typeArr.indexOf(type) > 0) { boolean = false; } if (boolean) { Toast(‘上传图片格式不支持!请选择‘ + this.typeArr); return false; } this.client.multipartUpload(storeAs, file).then(function (result) { self.data.url = result.res.requestUrls[0].split(‘?‘)[0]; }).catch(function (err) { console.log(err); }); }, getUuid() { var len = 32; //32长度 var radix = 16; //16进制 var chars = ‘0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz‘.split(‘‘); var uuid = [], i; radix = radix || chars.length; if (len) { for (i = 0; i < len; i++) uuid[i] = chars[0 | Math.random() * radix]; } else { var r; uuid[8] = uuid[13] = uuid[18] = uuid[23] = ‘-‘; uuid[14] = ‘4‘; for (i = 0; i < 36; i++) { if (!uuid[i]) { r = 0 | Math.random() * 16; uuid[i] = chars[(i == 19) ? (r & 0x3) | 0x8 : r]; } } } return uuid.join(‘‘); } } } </script> <style scoped lang="less"> .file { position: relative; left: .26rem; top: .2rem; display: inline-block; background: #32d582; border: 1px solid #99D3F5; border-radius: 4px; padding: 4px 12px; overflow: hidden; color: white; text-decoration: none; text-indent: 0; line-height: 20px; } .file input { position: absolute; font-size: 100px; right: 0; top: 0; opacity: 0; } </style>
父级组件:
<up-Load class="files" :data="item"
typeArr="image/png,image/jpg,image/gif,image/jpeg" size="50000"></up-Load>
