最近在搞鸿蒙Next自动化，HDC命令作为最基础的调试工具，发现全网没有比较完整的命令介绍，于是整理了这篇文档。

由于鸿蒙生态还处于初期，官方提供的hdc命令还在不断修改中，这篇文档更新不及时，请以github为准https://github.com/codematrixer/awesome-hdc

HDC（OpenHarmony Device Connector） 是为鸿蒙开发/测试人员提供的用于设备调试的命令行工具，类似Android端的ADB工具。

HDC主要有三部分组成

1. hdc client：运行于电脑上的客户端，用户可以在电脑命令终端（windows cmd/linux shell）下请求执行相应的hdc命令。
2. hdc server：作为后台进程也运行于电脑上，server管理client和设备端daemon之间通信包括连接的复用、数据通信包的收发，以及个别本地命令的直接处理。
3. hdc daemon：daemon部署于OpenHarmony设备端作为守护进程按需运行，负责处理来自client端请求。
   

整体架构和Android系统的ADB架构非常类似。

HDC安装

• 下载 Command Line Tools 并解压

• hdc文件在command-line-tools/sdk/HarmonyOS-NEXT-DB2/openharmony/toolchains目录下

• 配置电脑环境变量，以macOS为例，在~/.bash_profile 或者 ~/.zshrc文件中添加如下内容：

export HM_SDK_HOME="/Users/develop/command-line-tools/sdk/HarmonyOS-NEXT-DB2"  //请以sdk实际安装目录为准
export PATH=$PATH:$HM_SDK_HOME/hms/toolchains:$HM_SDK_HOME/openharmony/toolchains
export HDC_SERVER_PORT=7035

也可以自行编译安装：参考鸿蒙官方gitree文档

基本用法

基本语法

hdc -t  

如果只有一个设备/模拟器连接时，可以省略掉-t 这一部分，直接使用hdc 。在多个设备/模拟器连接的情况下需要指定-t 参数， connectKey可以通过hdc list targets命令获取，对应Android里的adb devices获取的serialNumber。

$ hdc list targets

127.0.0.1:5555    //:形式的connectKey ，一般为无线连接的设备或模拟器
FMR0223C13000649

比如给FMR0223C13000649 这个设备安装应用：

$ hdc -t FMR0223C13000649 install entry-default-signed.hap

[Info]App install path:/Users/develop/entry-default-signed.hap, queuesize:0, msg:install bundle successfully.
AppMod finish

注意事项

• 使用hdc，如果出现异常，可以尝试通过hdc kill -r命令杀掉并重启hdc服务。
• 如果出现hdc list targets获取不到设备信息的情况，可以通过任务管理器查看是否有hdc进程存在。若进程存在，则通过hdc kill -r命令杀掉该进程。

设备连接管理

查看HDC版本

$ hdc -v

Ver: 2.0.0a

启动/停止 HDC Server

停止

$ hdc kill

Kill server finish

重启

$ hdc start -r

查询设备列表

$ hdc list targets

127.0.0.1:5555
FMR0223C13000649

-v 选项 显示详细信息

$ hdc list targets -v

127.0.0.1:5555		  TCP	  Connected	  localhost
FMR0223C13000649		USB	  Connected	  unknown...

输出的内容第一列为设备的connectKey， 第二列是设备连接方式，第三列为设备连接状态，第四列暂时未知

查询设备UDID

$ hdc shell bm get --udid

udid of current device is :
C46284C052AE01BBD2358FE44B279524B508FC959AAB5F4B0B74E42A06569B7E

这个udid在用开发者账号打包时，需要添加这个udid到对应的profile文件中

重启手机

$ hdc target boot

查看屏幕旋转状态

$ hdc shell hidumper -s DisplayManagerService -a -a

通过上面的查看屏幕信息命令，通过正则提取ScreenRotation字段即可，ScreenRotation有四个值：

• 0：未旋转
• 90：顺时针旋转90度
• 180：顺时针旋转180度
• 270：顺时针旋转270度

备注：目前旋转状态只能查看，不支持设置

启动应用

通过启动Ability来拉起APP

hdc shell aa start -a {abilityName} -b {bundleName} 

• 其中bundleName可以通过hdc shell bm dump -a获取

• 其中abilityName可以通过如下命令获取（查看当前任务栈的ability信息）

$ hdc shell aa dump -l    # 运行命令前需要手动打开app

User ID #100
  current mission lists:{
    Mission ID #139  mission name #[#com.kuaishou.hmapp:kwai:EntryAbility]  lockedState #0  mission affinity #[]
      AbilityRecord ID #55
        app name [com.kuaishou.hmapp]
        main name [EntryAbility]
        bundle name [com.kuaishou.hmapp]
        ability type [PAGE]
        state #FOREGROUND  start time [152523]
        app state #FOREGROUND
        ready #1  window attached #0  launcher #0
        callee connections:
        isKeepAlive: false
 }

里面的EntryAbility就是你要打开app的Ability名称

退出应用

强制退出应用

hdc shell aa force-stop {bundleName} 

• 其中bundleName可以通过hdc shell bm dump -a获取

获取应用版本

$ hdc shell bm dump -n {bundleName}

执行上述命令后，再解析json, 提取versionName字段即可

清除应用缓存

$ hdc shell bm clean -n {bundleName}  -c

clean bundle cache files successfully.

其中bundleName可以通过hdc shell bm dump -a获取， 比如com.kuaishou.hmapp

清除应用数据

$ hdc shell bm clean -n {bundleName} -d

端口转发

显示端口转发列表

展示电脑端口转发到手机端口的列表

$ hdc fport ls

FMR0223C13000649    tcp:7912 tcp:7912    [Forward]

本地端口转发到手机

将本地电脑的7913端口转发到手机7912端口

$ hdc fport tcp:7913 tcp:7912

Forwardport result:OK

这个命令非常实用，比如我再手机上实现了一个 http服务，没有这个命令前需要通过手机ip:port来访问，这就需要提前知道手机的wlanIP，执行这个命令后可以直接通过localhost:localPort来访问手机里的服务。

删除端口转发任务

$ hdc fport rm tcp:7913 tcp:7912
Remove forward ruler success, ruler:tcp:7913 tcp:7912

$ hdc fport ls
[Empty]

同理，rport命令表示手机端口转发到电脑端口，我就不一一举例了.

无线调试

1. 在手机上开启5555端口 hdc -t {SERIAL} tmode port {PORT}
2. 连接手机上的端口 hdc -t {SERIAL} tconn {WLANIP}:{PORT}
3. 恢复手机USB连接 hdc -t {SERIAL} tmode usb

示例

$ hdc tmode port 5555

$ hdc tconn 172.31.124.84:5555
Connect OK

$ hdc list targets
172.31.124.84:5555

$ hdc tmode usb      
Set device run mode successful.

不过目前这个无线调试，会导致该手机USB连接方式断开，导致无法进行端口转发，每次进行无线调试时，需要知道手机的wlanip才行。
这个问题也在和鸿蒙方沟通，待解决。
记个TODO.

文件传输

从本地电脑发送文件至手机

$ hdc file send ~/layout_407568854.json /data/local/tmp/layout_407568854.json

FileTransfer finish, Size:71792, File count = 1, time:24ms rate:2991.33kB/s

从手机拷贝文件至本地电脑

$ hdc file recv /data/local/tmp/layout_407568854.json ~/layout_407568854.json

[I][2024-05-28 20:15:45] HdcFile::TransferSummary success

UI模拟操作(点击滑动等)

支持操作类型：点击 双击 长按 慢滑 快滑 拖拽 输入文字 KeyEvent

举例

//点击
hdc shell uitest uiInput click 100 100

//双击
hdc shell uitest uiInput doubleClick 100 100

//长按
hdc shell uitest uiInput longClick 100 100

//快滑
hdc shell uitest uiInput fling 10 10 200 200 500

//慢滑
hdc shell uitest uiInput swipe 10 10 200 200 500

//拖拽
hdc shell uitest uiInput drag 10 10 100 100 500

//左滑
hdc shell uitest uiInput dircFling 0 500

//右滑
hdc shell uitest uiInput dircFling 1 600

//上滑
hdc shell uitest uiInput dircFling 2

//下滑
hdc shell uitest uiInput dircFling 3

//输入框输入
hdc shell uitest uiInput inputText 100 100 hello

//返回主页
hdc shell uitest uiInput keyEvent Home

//返回上一步
hdc shell uitest uiInput keyEvent Back

//组合键粘贴操作
hdc shell uitest uiInput keyEvent 2072 2038

keyEvent映射表可以参考这个文档：https://docs.openharmony.cn/pages/v4.1/en/application-dev/reference/apis-input-kit/js-apis-keycode.md

屏幕截图

hdc提供了两种截图命令

方式一

$ hdc shell uitest screenCap
// 默认存储路径：/data/local/tmp，文件名：时间戳 + .png。

$ hdc shell uitest screenCap -p /data/local/tmp/1.png
// 指定存储路径和文件名。

【推荐】方式二

$ hdc shell snapshot_display -f /data/local/tmp/2.jpeg
// 截图完成后可以通过 hdc file recv 命令导入到本地

方式二的截图性能效率远远高于方式一

屏幕录屏

相关hdc命令还未支持，官方在开发中。。。

我这边通过python脚本实现了录屏功能，使用方法如下

cd awesome-hdc/scripts
pip3 install -r requirements.txt

python3 screen_recroding.py

打开Scheme (URL)

$ hdc shell aa start -U http://www.baidu.com
start ability successfully.

$ hdc shell aa start -U kwai://home

获取页面布局信息（控件树）

$ hdc shell uitest dumpLayout -p {saveDumpPath}   # 运行命令前需要手动打开app，进入对应页面

DumpLayout saved to:/data/local/tmp/layout_407568854.json

• -p表示控件树保存的目录，如果不指定，则默认保存在手机的/data/local/tmp目录
  /data/local/tmp/layout_407568854.json文件内容如下：

{
    "attributes": {
        "accessibilityId": "",
        "bounds": "[0,0][1260,2720]",
        "checkable": "",
        "checked": "",

        "type": ""
    },
    "children": [
    	
      ...
      
    ]

录制用户操作

将当前界面操作记录到/data/local/tmp/layout/record.csv，结束录制操作使用Ctrl+C结束录制

$  hdc shell uitest uiRecord record

windowBounds : (0,0,1260,2720)
Current ForAbility :com.kuaishou.hmapp, EntryAbility
The result will be written in csv file at location: /data/local/tmp/layout/record.csv

• uiRecord read, 将文件内容打印到控制台

录制完成后，再将csv文件拷贝到电脑上

$ hdc file recv  /data/local/tmp/layout/record.csv ~/record.csv

  Log type "app" is used for applications, the range is [0x0,  0xffff]
  To reduce redundant info when printing logs, only last five hex numbers of domain are printed
  So if user wants to use -D option to filter OS logs, user should add 0xD0 as prefix to the printed domain:
  Exapmle: hilog -D 0xD0xxxxx
  The xxxxx is the domain string printed in logs.

性能工具

SmartPerf是一款基于系统开发的性能功耗测试工具，操作简单易用。工具可以检测性能、功耗相关指标，包括FPS、CPU、GPU、RAM、Temp等，通过量化的指标项了解应用性能状况。在开发过程中，使用的可能是有屏或无屏设备，对此SmartPerf提供了两种方式：分别是SmartPerf-Device和SmartPerf-Daemon。SmartPerf-Device适用于有屏设备，支持可视化操作。测试时是通过悬浮窗的开始和暂停来实时展示性能指标数据，保存后可生成数据报告，在报告中可分析各指标数据详情。SmartPerf-Daemon支持shell命令行方式，同时适用于有屏和无屏设备。

• CPU：每秒读取一次设备节点下CPU大中小核的频点和各核使用率，衡量应用占用CPU资源的情况，占用过多的CPU资源会导致芯片发烫。
• GPU：每秒读取一次设备节点下GPU的频点和负载信息，衡量应用占用GPU资源的情况，当GPU占用过多时，会导致性能下降，应用程序的运行速度变慢。
• FPS：应用界面每秒刷新次数，衡量应用画面的流畅度，FPS越高表示图像流畅度越好，用户体验也越好。
• POWER：每秒读取一次设备节点下的电流及电压信息。
• TEMP：每秒读取一次设备节点下电池温度、系统芯片温度等信息。
• RAM：每秒读取一次应用进程的实际物理内存，衡量应用的内存占比情况。
• snapshot：每秒截取一张应用界面截图。

$ hdc shell

# SP_daemon
