|
||||
```js
|
||||
import { fileToDataURL, dataURLToFile, processFile, ProcessFileOptions } from '@/uni_modules/lime-file-utils'
|
||||
const url = ref('')
|
||||
const src = ref('')

path: '/static/logo.png',
|
||||
success: (res: string)=>{
|

}
|
||||

|
||||
|
||||
## fileToDataURL
|
||||
将`文件`或`图片`转成 `URL（data URL）`,接收一个文件路径，APP 返回的是`DataURL`或`null`, 非APP 返回的是`Promise<string>`
|
||||
|
||||
```js
|
||||
fileToDataURL(filePath : string)
|
||||
```
|
||||
|
||||
## fileToBase64
|
||||
将`文件`或`图片`转成 `Base64`, 接收一个文件路径，APP 返回的是`Base64`或`null`, 非APP 返回的是`Promise<string>`
|
||||
|
||||
```js
|
||||
fileToBase64(filePath : string)
|
||||
```
|
||||
|
||||
## dataURLToFile
|
||||
将 `Base64` 编码的数据 `URL（data URL）`保存为临时路径，接收一个dataURL，参数`filename`为可选, APP返回的是`string`或`null`,非APP 返回的是`Promise<string>`
|
||||
|
||||
```js
|
||||
dataURLToFile(dataURL : string, filename : NullableString = null)
|
||||
```
|
||||
|
||||
## processFile
|
||||
是上面三个函数的总和，接收`ProcessFileOptions`
|
||||
|
||||
```js
|
||||
processFile({
|
||||
type: 'toBase64' | 'toDataURL' | 'toFile',
|
||||
path: string,
|
||||
filename?: string,//如果是toFile,则可以设置保存文件的文件名
|
||||
success ?: (res : string) {},
|
||||
fail ?: (res : any) {},
|
||||
complete ?: (res : any) {}
|
||||
} as ProcessFileOptions)
|
||||
```
