首先下載依賴：

cnpm i -S vue-uuid ali-oss

圖片和視頻字段都是數組類型，保證可以上傳多個文件。

使用：

<UploadImageVideo ref='ref_UploadImageVideo' bucket='xxx' :currentUrls='formData.imgurl' :limitFileNumber='3' tip='1、最多上傳3張照片; 2、上傳圖片只能是 JPEG/JPG/PNG 格式; 3、單張圖片大小不能超過 5MB!' fileType='image' :isMultiple='true'></UploadImageVideo> fileType可選。默認不寫，表示圖片、視頻都可上傳。fileType='image'表示只能上傳圖片。fileType='video'表示只能上傳視頻 bucket必選。 isMultiple可選。默認為false currentUrls必選。當前目前已有的文件服務器url數組。通常新增文件時，傳入的currentUrls為空數組[]；更新文件時，傳入到currentUrls為非空數組 tip可選。提示內容

提供的方法：（當前組件中所有的上傳都是批量上傳，且為分片上傳，以展示上傳進度條）

UpdateFiles()。更新文件數據。上傳新數據到服務器，并刪除服務器中的舊數據，返回更新后的url數組 addFiles()。批量上傳文件。返回成功上傳的url數組 deleteMultiFiles(urls = [])。批量刪除服務器中的文件。參數：待刪除到服務器文件url數組。 UploadImageVideo(filename, file)。分片上傳數據，可展示進度條。上傳重命名后的文件到alioss, 并返回單個文件url字符串。可支持中文文件名

調用組件中的方法：例如可通過 let urls = await this.$refs['ref_UploadImageVideo'].addFiles();調用批量上傳圖片或視頻的方法
