H A Dfaqs-file-management.md7 开发者调用picker接口保存文件返回uri，调用fs.openSync()接口打开该文件时传入了读写权限：fs.OpenMode.READ_WRITE，无法正常打开文件
18 fs.openSync(uri, fs.OpenMode.WRITE_ONLY)
45 可以通过调用函数fs.open来实现，open(path: string, mode?: number)，指定第二个参数mode为fs.OpenMode.CREATE，表示若文件不存在，则创建文件。
65 ## “datashare://”路径使用fs.open可以打开，但使用fs.copyFile会报错(API 9)
87 1. 使用fs.openSyn获取json文件的fd。
90 import fs from '@ohos.file.fs';
91 let sanFile = fs.open(basePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
95 2. 通过fs.readSync读取json文件内容。
98 let content = fs.readSync(basePath);
113 fs的具体使用可以参考：[@ohos.file.fs](../reference/apis-core-file-kit/js-apis-file-fs.md)
