证件图片识别上传
根据业务需要，经常涉及到证件上传，例如身份证上传、银行卡、营业执照等信息，根据设计师的设计，单独封装了一个上传组件。识别接口后端用的是阿里云的。
上传组件用的是 element-plus el-upload 上代码：
<template>
<div class="component-upload-image">
<el-upload
:action="uploadUrl"
list-type="picture-card"
:on-success="handleUploadSuccess"
:before-upload="handleBeforeUpload"
:limit="limit"
:on-error="handleUploadError"
:on-exceed="handleExceed"
ref="imageUpload"
:before-remove="handleDelete"
:data="params"
name="file"
:show-file-list="true"
:headers="headers"
v-model:file-list="fileList"
:on-preview="handlePictureCardPreview"
:class="{ hide: fileList.length >= limit }">
<el-icon class="avatar-uploader-icon">
<plus />
</el-icon>
</el-upload>
<!-- 上传提示 -->
<div class="el-upload__tip" v-if="showTip">
请上传
<template v-if="fileSize">
大小不超过 <b style="color: #f56c6c">{{ fileSize }}MB</b>
</template>
<template v-if="fileType">
格式为 <b style="color: #f56c6c">{{ fileType.join("、") }}</b>
</template>
的文件
</div>
<template v-if="showTipButton">
<el-button link type="primary" @click="showDiagram = !showDiagram" icon="InfoFilled">查看示意图</el-button>
</template>
<el-image class="tip-img" :src="diagram" fit="contain" :preview-src-list="[diagram]" v-if="showDiagram" :preview-teleported="true"></el-image>
<el-dialog v-model="dialogVisible" title="预览" width="800px" append-to-body>
