hdc组件

简介

hdc(Harmony Device Connector) 是OpenHarmony为开发人员提供的用于调试的命令行工具,开发机器上使用设备连接器hdc client/server命令行工具,该工具需支持部署在Windows/Linux/Mac等系统上与鸿蒙设备(或模拟器)进行连接调试通信。PC端hdc工具需要针对以上开发机操作系统平台分别发布相应的版本,设备端hdc daemon需跟随设备镜像发布包括对模拟器进行支持。下文将介绍hdc的常用命令及使用举例。

架构

hdc主要有三部分组成:

  1. hdc client部分:运行于开发机上的客户端,用户可以在开发机命令终端(windows cmd/linux shell)下请求执行相应的hdc命令,运行于开发机器,其它的终端调试IDE也包含hdc client。

  2. hdc server部分:作为后台进程也运行于开发机器,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部分:daemon部署于鸿蒙设备端作为守护进程来按需运行,负责处理来自client端的请求。

使用说明

hdc当前支持如下命令:

表 1 hdc命令列表

Option

Description

-t key

用于指定连接该指定设备识Key

举例:hdc -t *****(设备id) shell

-s socket

用于指定服务监听的socket配置

举例:hdc -s ip:port

-h/help -v/version

用于显示hdc相关的帮助、版本信息

list targets[-v]

显示所有已经连接的目标设备列表,-v选项显示详细信息

举例: hdc list targets

target mount

以读写模式挂载/system等分区

举例: hdc target mount

smode [off]

授予后台服务进程root权限, 使用off参数取消授权

举例: hdc smode

kill [-r]

终止hdc服务进程, -r选项会触发再次重启hdc server

举例: hdc kill

start [-r]

启动hdc服务进程, -r选项会触发重启hdc server

举例: hdc start

tconn host[:port][-remove]

通过【ip地址:端口号】来指定连接的设备

举例: hdc tconn 192.168.0.100:10178

tmode usb

执行后设备端对应daemon进程重启,并首先选用usb连接方式

tmode port port-number

执行后设备端对应daemon进程重启,并优先使用网络方式连接设备,如果连接设备再选择usb连接

file send local remote

从host端发送文件至设备

举例: hdc file send E:\a.txt /data/local/tmp/a.txt

file recv [-a] remote local

从设备端拉出文件至本地host端

举例: hdc file recv /data/local/tmp/a.txt ./a.txt

install [-r/-d/-g] package

安装OpenHarmony package

举例: hdc install E:\***.hap

uninstall [-k] package

卸载OpenHarmony应用

hilog

支持查看抓取hilog调试信息

举例: hdc hilog

shell [command]

远程执行命令或进入交互命令环境

举例: hdc shell

以下是常用hdc命令示例,供开发者参考:

  • 查看设备连接信息

    hdc list targets
  • 往设备中推送文件

    hdc file send  E:\a.txt  /data/local/tmp/a.txt
  • 从设备中拉取文件

    hdc file recv  /data/local/tmp/a.txt   ./a.txt
  • 安装应用

    hdc install E:\***.hap
  • 查看日志

    hdc hilog
  • 进入命令行交互模式

    hdc shell
  • 网络连接。

    hdc tconn 192.168.0.100:8710
