简介

tar支持tar打包和tar解包功能。

下载安装

ohpm install @ohos/tar

OpenHarmony ohpm环境配置等更多内容,请参考 如何安装OpenHarmony ohpm包

使用说明

  1. 在page页面引入包
import { OHOSTar, GlobalContext } from "@ohos/tar"
import fs from '@ohos.file.fs';
  1. 创建OHOStarTestInit类
class OHOStarTestInit {

 private static instance: OHOStarTestInit;
 rootPath: string = GlobalContext.getContext().getObject('filesDir') as string

 public static getInstance(): OHOStarTestInit {
   if (!OHOStarTestInit.instance) {
     OHOStarTestInit.instance = new OHOStarTestInit();
   }
   return OHOStarTestInit.instance;
 }

 public GetDirName(): string {
   return this.rootPath + '/' + "tartestdir";
 }

 // tartest初始化
 TestTarInit(): void {
   fs.mkdir(this.GetDirName(), (err) => {
     if (err) {
       console.info("mkdir failed with error message:" + err.message + ",errorcode:" + err.code);
     } else {
       let filePath = this.GetDirName() + "/test.txt";
       let file = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
       fs.write(file.fd, "1234567890abcdefghij", (err) => {
         if (err) {
           console.info("write failed with error message: " + err.message + " error code: " + err.code);
         } else {
           fs.closeSync(file);
         }
       });
     }
   });
 }

 // untartest初始化
 TestUnTarInit(): void {
   fs.rmdir(this.GetDirName()); // 删除 tartestdir目录
 }

 //重置
 public DirReset() {
   fs.listFile(this.rootPath, (err, filenames) => {
     if (err) {
       console.info("list file failed with error message: " + err.message + ", error code: " + err.code);
     } else {
       for (let i = 0; i < filenames.length; i++) {
         let deleteFile = this.rootPath + '/' + filenames[i]
         if(fs.statSync(deleteFile).isDirectory()){
           fs.rmdirSync(deleteFile);
         }else{
           fs.unlink(deleteFile);
         }
       }
     }
   });
 }
}
  1. 创建tar工具对象
 // 参数1:要操作的文件或文件夹的父目录;
 // 参数2:压缩生成的文件名;
 let tar: OHOSTar = new OHOSTar(OHOStarTestInit.getInstance().rootPath, "testdir");
  1. 初始化Tar测试环境,创建生成tartestdir目录,并且包含一些txt文件
  HOStarTestInit.getInstance().TestTarInit();
  1. Tar功能测试,运行后会将环境中的tartestdir目录打包为tartest.tar文件
  // 要压缩的文件夹名称
  tar.addTarPath("tartestdir");
  tar.tar();
  1. 初始化Untar测试环境
  OHOStarTestInit.getInstance().TestUnTarInit();
  1. Untar功能测试,运行后会将环境中的tartest.tar文件解包
  // 参数 path: 自定义解压路径,例:folder1/folder2,这个path是从压缩操作的父目录后面开始的目录(即rootPath后面)
  tar.untar("customUnTarPath/888");

以上功能测试均可通过在设备应用目录中查看

在设备shell中:

  1. 进入到应用files目录中
   # cd /data/app/el2/100/base/cn.openharmony.jtar/haps/entry/files
  1. 点击Tar Init,会生成tartestdir,tartestdir中包含一个txt文件
   # ls
   tartestdir
   # ls tartestdir/
   test.txt
  1. 点击Tar,会打包生成对应的tartest.tar文件
   # ls
   tartest.tar  tartestdir
  1. 点击UnTar Init,生成对应的tartest.tar文件
   # ls
   tartest.tar
  1. 点击UnTar,生成对应的tartest.tar文件的原始文件
   # ls
   tartest.tar  tartestdir
   # ls tartestdir
   test.txt

接口说明

  1. 修改生成的tar文件名 setTarName(name: string)

  2. 修改解包目标的Untar文件名 setUnTarName(name: string)

  3. 修改解包目标的Untar路径 setUnTarPath(path: string)

  4. 添加一个需要tar的文件或目录 addTarPath(path: string)

  5. 删除一个需要tar的文件或目录 delTarPath(path: string)

  6. tar打包 tar(): number

  7. untar解包 untar(path?: string): number
