vue 传base64到后台后台传到oss的java实现
2024-06-15 19:07:04
近期项目中需要将前台vue穿过来base64格式的图片记录保存存到阿里云oss上，通过网上找的一些方法结合自己的实际情况终于实现了，下面直接上代码：
前台vue代码：
<template>
<div class="insti-container">
<div v-if="mediciner">
<h2>营业执照</h2>
<div class="loadImg">
<div id="img-group">
<div class="img-item" style="display:none">
<img id="seeimg" :src="imgUrl" alt="">
</div>
</div>
<div id="ossfile">加载上传插件失败!<a class ='btn'>刷新</a></div>
<div class="add-pic Single" @click="uploadImg" id="container">
<a id="selectfiles" href="javascript:void(0);" class='btn'></a>
</div>
</div>
</div>
<h2>上传资质照片（<span>{{curNumber}}</span>/9）</h2>
<div class="loadImg">
<div id="img-group">
<div class="img-item" v-for="(item,index) in inspect" :key="index" @click="delectImg(index)">
<img :src="item" alt="">

</div>
</div>
<div class="add-pic" @click="addPic()" v-show="picFlag">
