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>

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>

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>

dataURLToFile(dataURL : string, filename : NullableString = null)

processFile

是上面三个函数的总和，接收ProcessFileOptions

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)
