在mounted中通過接口得到images數據，并賦值給el-upload中的file-list，為什么圖片不顯示？<el-upload :action="cdn"
:file-list="images"
:before-upload="beforeUpload"
:on-preview="onPreview"
:on-remove="(file, fileList) => onRemove(fileList, 'detail')"
:on-success="(response, file, fileList) => onSuccess(response, 'detail')"
:data="{entity: 'product'}"
list-type="picture-card" multiple>
<i class="el-icon-plus"></i>
</el-upload>
