鸿蒙文件操作事前准备

13900001，沙箱13900002

首选授权

module授权配置 "requestPermissions": [{ "name": "ohos.permission.CAMERA",}, { "name": "ohos.permission.READ_MEDIA",}, { "name": "ohos.permission.WRITE_MEDIA", }, { "name": "ohos.permission.MEDIA_LOCATION"}  ]

//EntryAbility下获取定义沙箱路径

onWindowStageCreate(windowStage: window.WindowStage) { // Main window is created, set main page for this ability let context = this.context; globalThis.pathDir =`${context.filesDir.split('files')[0]}cache/`; }

其次再进行文件操作
