Vue组件封装上传图片和视频的示例代码

Vue组件封装上传图片和视频的示例代码，久久派带你了解更多相关信息。

首先下载依赖：

cnpm i -S vue-uuid ali-oss

图片和视频字段都是数组类型，保证可以上传多个文件。

UploadImageVideo：

使用：

<UploadImageVideo  ref=\"ref_UploadImageVideo\"  bucket=\"xxx\"  :currentUrls=\"formData.imgurl\"  :limitFileNumber=\"3\"  tip=\"1、最多上传3张照片; 2、上传图片只能是 JPEG/JPG/PNG 格式; 3、单张图片大小不能超过 5MB!\"  fileType=\"image\"  :isMultiple=\"true\"></UploadImageVideo>

• fileType可选。默认不写，表示图片、视频都可上传。fileType=\”image\”表示只能上传图片。fileType=\”video\”表示只能上传视频
• bucket必选。
• isMultiple可选。默认为false
• currentUrls必选。当前目前已有的文件服务器url数组。通常新增文件时，传入的currentUrls为空数组[]；更新文件时，传入到currentUrls为非空数组
• tip可选。提示内容

提供的方法：（当前组件中所有的上传都是批量上传，且为分片上传，以展示上传进度条）

1. UpdateFiles()。更新文件数据。上传新数据到服务器，并删除服务器中的旧数据，返回更新后的url数组
2. addFiles()。批量上传文件。返回成功上传的url数组
3. deleteMultiFiles(urls=[])。批量删除服务器中的文件。参数：待删除到服务器文件url数组。
4. UploadImageVideo(filename,file)。分片上传数据，可展示进度条。上传重命名后的文件到alioss,并返回单个文件url字符串。可支持中文文件名

调用组件中的方法：例如可通过 leturls=awaitthis.$refs[\”ref_UploadImageVideo\”].addFiles();调用批量上传图片或视频的方法
