首先下载依靠:
- cnpm i -S vue-uuid ali-oss
复制代码
图片和视频字段都是数组范例,包管可以上传多个文件。

利用:- <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>
复制代码
- 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:(当前组件中全部的上传都是批量上传,且为分片上传,以展示上传进度条)
- 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
- addFiles()。批量上传文件。返回乐成上传的url数组
- 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。
- 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 <strong>let urls = await this.$refs["ref_UploadImageVideo"].addFiles();调用批量上传图片或视频的方法</strong>
