想要让您的Samsungctl智能电视遥控器功能更加强大吗？本教程将为您详细介绍如何扩展Samsungctl项目，实现自定义按键映射和插件开发，让您的电视控制体验达到全新高度！😊

Samsungctl是一个强大的Python库和命令行工具，用于通过网络连接远程控制三星智能电视。无论您是普通用户还是开发者，通过本指南都能轻松掌握扩展技巧，打造个性化的电视控制方案。

📋 了解Samsungctl项目结构

在开始扩展之前，让我们先了解Samsungctl的核心架构。项目的主要文件包括：

samsungctl/init.py- 主模块入口文件
samsungctl/remote.py- 远程控制基类
samsungctl/remote_legacy.py- 旧版电视控制实现
samsungctl/remote_websocket.py- 新版Tizen电视控制实现
samsungctl.conf- 默认配置文件

Samsungctl支持两种连接方式：传统协议（legacy）和WebSocket协议（websocket），分别对应不同年代的三星电视型号。

🔧 自定义按键映射配置

1. 创建自定义按键映射文件

首先，您需要了解Samsungctl支持的按键代码。在samsungctl/remote.py中，control()方法负责发送按键命令。您可以创建一个自定义的按键映射模块来扩展功能：

# custom_keys.py CUSTOM_KEY_MAPPINGS = { # 自定义按键映射 "KEY_CUSTOM_VOLUP": "KEY_VOLUP", "KEY_CUSTOM_VOLDOWN": "KEY_VOLDOWN", "KEY_CUSTOM_MUTE": "KEY_MUTE", # 组合按键 "KEY_SMART_HUB": "KEY_CONTENTS", "KEY_NETFLIX": "KEY_CONTENTS", # 需要配合其他操作 "KEY_YOUTUBE": "KEY_CONTENTS", # 需要配合其他操作 }

2. 扩展Remote类支持自定义按键

您可以创建一个继承自原始Remote类的新类，添加自定义按键处理逻辑：

# custom_remote.py import samsungctl from samsungctl import Remote class CustomRemote(Remote): def __init__(self, config, custom_mappings=None): super().__init__(config) self.custom_mappings = custom_mappings or {} def custom_control(self, key): """支持自定义按键映射的控制方法""" # 检查是否为自定义按键 if key in self.custom_mappings: mapped_key = self.custom_mappings[key] return self.control(mapped_key) # 直接发送原始按键 return self.control(key) def send_macro(self, keys, delay=0.5): """发送宏命令，支持按键序列""" import time for key in keys: self.custom_control(key) time.sleep(delay)

3. 配置文件增强

修改samsungctl.conf配置文件，添加自定义按键映射支持：

{ "name": "samsungctl", "description": "PC", "id": "", "method": "legacy", "port": 55000, "timeout": 0, "custom_keys": { "KEY_MY_VOLUME_UP": "KEY_VOLUP", "KEY_MY_VOLUME_DOWN": "KEY_VOLDOWN", "KEY_MY_POWER": "KEY_POWEROFF" } }

🚀 插件系统开发教程

1. 插件架构设计

创建一个灵活的插件系统，让Samsungctl可以轻松扩展新功能：

# plugins/base.py class SamsungctlPlugin: """插件基类""" def __init__(self, remote, config=None): self.remote = remote self.config = config or {} def initialize(self): """插件初始化""" pass def execute(self, command, *args, **kwargs): """执行插件命令""" raise NotImplementedError def cleanup(self): """插件清理""" pass

2. 音量控制插件示例

创建一个实用的音量控制插件：

# plugins/volume_control.py from .base import SamsungctlPlugin class VolumeControlPlugin(SamsungctlPlugin): """音量控制插件""" def __init__(self, remote, config=None): super().__init__(remote, config) self.max_volume = config.get('max_volume', 100) self.min_volume = config.get('min_volume', 0) def set_volume(self, level): """设置指定音量级别""" if level < self.min_volume or level > self.max_volume: raise ValueError(f"音量必须在{self.min_volume}-{self.max_volume}之间") # 获取当前音量 current = self.get_current_volume() # 调整到目标音量 if current < level: for _ in range(level - current): self.remote.control("KEY_VOLUP") else: for _ in range(current - level): self.remote.control("KEY_VOLDOWN") def mute_toggle(self): """静音切换""" self.remote.control("KEY_MUTE") def get_current_volume(self): """获取当前音量（需要电视支持）""" # 这里可以扩展为通过其他方式获取音量 return 50 # 默认值

3. 应用程序启动插件

创建应用程序启动插件，快速打开电视上的应用：

# plugins/app_launcher.py from .base import SamsungctlPlugin class AppLauncherPlugin(SamsungctlPlugin): """应用程序启动插件""" def __init__(self, remote, config=None): super().__init__(remote, config) self.app_mappings = config.get('app_mappings', { 'netflix': ['KEY_CONTENTS', 'KEY_RIGHT', 'KEY_ENTER'], 'youtube': ['KEY_CONTENTS', 'KEY_RIGHT', 'KEY_RIGHT', 'KEY_ENTER'], 'amazon': ['KEY_CONTENTS', 'KEY_RIGHT', 'KEY_RIGHT', 'KEY_RIGHT', 'KEY_ENTER'] }) def launch_app(self, app_name): """启动指定应用程序""" if app_name not in self.app_mappings: raise ValueError(f"未知应用程序: {app_name}") sequence = self.app_mappings[app_name] for key in sequence: self.remote.control(key) import time time.sleep(0.5) # 按键间隔 def list_apps(self): """列出所有支持的应用程序""" return list(self.app_mappings.keys())

🔌 插件管理器实现

1. 插件管理器类

创建一个插件管理器来统一管理所有插件：

# plugin_manager.py import importlib import os class PluginManager: """插件管理器""" def __init__(self, remote, plugin_dir="plugins"): self.remote = remote self.plugin_dir = plugin_dir self.plugins = {} def load_plugin(self, plugin_name, config=None): """加载单个插件""" try: # 动态导入插件模块 module = importlib.import_module(f"{self.plugin_dir}.{plugin_name}") plugin_class = getattr(module, plugin_name.title().replace('_', '')) # 实例化插件 plugin = plugin_class(self.remote, config) plugin.initialize() self.plugins[plugin_name] = plugin return plugin except ImportError as e: print(f"无法加载插件 {plugin_name}: {e}") return None def load_all_plugins(self, configs=None): """加载所有可用插件""" configs = configs or {} # 扫描插件目录 if os.path.exists(self.plugin_dir): for file in os.listdir(self.plugin_dir): if file.endswith('.py') and file != 'base.py': plugin_name = file[:-3] # 移除.py后缀 config = configs.get(plugin_name, {}) self.load_plugin(plugin_name, config) def execute_command(self, plugin_name, command, *args, **kwargs): """执行插件命令""" if plugin_name not in self.plugins: raise ValueError(f"插件未加载: {plugin_name}") return self.plugins[plugin_name].execute(command, *args, **kwargs) def cleanup_all(self): """清理所有插件""" for plugin in self.plugins.values(): plugin.cleanup() self.plugins.clear()

2. 使用示例

# example_usage.py import samsungctl from plugin_manager import PluginManager # 配置连接 config = { "name": "samsungctl", "description": "PC", "id": "", "host": "192.168.1.100", "port": 55000, "method": "legacy", "timeout": 0 } # 创建远程连接 with samsungctl.Remote(config) as remote: # 创建插件管理器 plugin_manager = PluginManager(remote) # 插件配置 plugin_configs = { "volume_control": { "max_volume": 100, "min_volume": 0 }, "app_launcher": { "app_mappings": { "netflix": ["KEY_CONTENTS", "KEY_RIGHT", "KEY_ENTER"], "youtube": ["KEY_CONTENTS", "KEY_RIGHT", "KEY_RIGHT", "KEY_ENTER"] } } } # 加载所有插件 plugin_manager.load_all_plugins(plugin_configs) # 使用音量控制插件 plugin_manager.execute_command("volume_control", "set_volume", 75) # 使用应用启动插件 plugin_manager.execute_command("app_launcher", "launch_app", "netflix") # 清理插件 plugin_manager.cleanup_all()

🎯 高级扩展技巧

1. 宏命令录制与回放

创建宏命令录制功能，让您可以将一系列操作保存并重复执行：

# plugins/macro_recorder.py from .base import SamsungctlPlugin import json import time class MacroRecorderPlugin(SamsungctlPlugin): """宏命令录制插件""" def __init__(self, remote, config=None): super().__init__(remote, config) self.macros = {} self.is_recording = False self.current_macro = [] def start_recording(self, macro_name): """开始录制宏命令""" if self.is_recording: raise RuntimeError("已经在录制中") self.is_recording = True self.current_macro = [] print(f"开始录制宏: {macro_name}") def stop_recording(self, macro_name): """停止录制并保存宏命令""" if not self.is_recording: raise RuntimeError("未在录制中") self.is_recording = False self.macros[macro_name] = self.current_macro.copy() self.save_macros() print(f"宏 {macro_name} 已保存，包含 {len(self.current_macro)} 个操作") def record_key(self, key): """录制按键操作""" if self.is_recording: self.current_macro.append({ 'type': 'key', 'key': key, 'timestamp': time.time() }) def play_macro(self, macro_name, speed=1.0): """播放宏命令""" if macro_name not in self.macros: raise ValueError(f"宏不存在: {macro_name}") macro = self.macros[macro_name] last_time = None for action in macro: if last_time is not None: # 保持原始时间间隔 delay = (action['timestamp'] - last_time) / speed if delay > 0: time.sleep(delay) if action['type'] == 'key': self.remote.control(action['key']) last_time = action['timestamp'] def save_macros(self): """保存宏命令到文件""" with open('macros.json', 'w') as f: json.dump(self.macros, f, indent=2) def load_macros(self): """从文件加载宏命令""" try: with open('macros.json', 'r') as f: self.macros = json.load(f) except FileNotFoundError: self.macros = {}

2. 定时任务调度器

创建定时任务功能，让电视在指定时间执行特定操作：

# plugins/scheduler.py from .base import SamsungctlPlugin import schedule import time from datetime import datetime class SchedulerPlugin(SamsungctlPlugin): """定时任务调度器插件""" def __init__(self, remote, config=None): super().__init__(remote, config) self.scheduled_tasks = [] def schedule_daily(self, time_str, callback, *args, **kwargs): """每天定时执行任务""" job = schedule.every().day.at(time_str).do(callback, *args, **kwargs) self.scheduled_tasks.append(job) print(f"已安排每日任务: {time_str}") def schedule_weekly(self, day, time_str, callback, *args, **kwargs): """每周定时执行任务""" day_map = { 'monday': schedule.every().monday, 'tuesday': schedule.every().tuesday, 'wednesday': schedule.every().wednesday, 'thursday': schedule.every().thursday, 'friday': schedule.every().friday, 'saturday': schedule.every().saturday, 'sunday': schedule.every().sunday } if day.lower() not in day_map: raise ValueError(f"无效的星期: {day}") job = day_map[day.lower()].at(time_str).do(callback, *args, **kwargs) self.scheduled_tasks.append(job) print(f"已安排每周任务: {day} {time_str}") def run_pending(self): """运行待执行的任务""" schedule.run_pending() def run_continuously(self, interval=1): """持续运行调度器""" import threading def run(): while True: self.run_pending() time.sleep(interval) thread = threading.Thread(target=run, daemon=True) thread.start() return thread

📊 测试与调试技巧

1. 创建测试脚本

# test_custom_remote.py import unittest from unittest.mock import Mock, patch import samsungctl from custom_remote import CustomRemote class TestCustomRemote(unittest.TestCase): def setUp(self): self.config = { "name": "test", "description": "Test", "id": "", "host": "192.168.1.100", "port": 55000, "method": "legacy", "timeout": 0 } def test_custom_key_mapping(self): """测试自定义按键映射""" custom_mappings = { "KEY_MY_VOLUP": "KEY_VOLUP", "KEY_MY_VOLDOWN": "KEY_VOLDOWN" } with patch('samsungctl.RemoteLegacy') as mock_remote: remote = CustomRemote(self.config, custom_mappings) remote.custom_control("KEY_MY_VOLUP") # 验证调用了正确的按键 mock_remote.return_value.control.assert_called_with("KEY_VOLUP") def test_macro_support(self): """测试宏命令支持""" with patch('samsungctl.RemoteLegacy') as mock_remote: remote = CustomRemote(self.config) keys = ["KEY_VOLUP", "KEY_VOLUP", "KEY_VOLUP"] remote.send_macro(keys, delay=0.1) # 验证调用了正确次数的按键 self.assertEqual(mock_remote.return_value.control.call_count, 3) if __name__ == '__main__': unittest.main()

2. 日志记录与调试

# debug_utils.py import logging from functools import wraps def debug_log(func): """调试日志装饰器""" @wraps(func) def wrapper(*args, **kwargs): logging.debug(f"调用 {func.__name__}，参数: {args}, {kwargs}") try: result = func(*args, **kwargs) logging.debug(f"{func.__name__} 返回: {result}") return result except Exception as e: logging.error(f"{func.__name__} 出错: {e}") raise return wrapper class DebugRemote: """调试版远程控制器""" def __init__(self, remote): self.remote = remote @debug_log def control(self, key): """带调试日志的control方法""" return self.remote.control(key) @debug_log def custom_control(self, key): """带调试日志的自定义control方法""" if hasattr(self.remote, 'custom_control'): return self.remote.custom_control(key) return self.remote.control(key)
