Accessibility API Setup

Requesting Permissions

import Cocoa
import ApplicationServices

func requestAccessibilityPermissions() -> Bool {
    let options = [kAXTrustedCheckOptionPrompt.takeUnretainedValue() as String: true]
    let accessEnabled = AXIsProcessTrustedWithOptions(options as CFDictionary)

    if !accessEnabled {
        print("请在系统偏好设置 -> 安全性与隐私 -> 辅助功能 中授权")
    }

    return accessEnabled
}

Main Entry Point

// main.swift
import Foundation

class MacOSAgent {
    let monitor: WeChatMonitor
    let inputWriter: InputWriter
    let commandReceiver: CommandReceiver

    init() {
        self.monitor = WeChatMonitor(intervalMs: 500)
        self.inputWriter = InputWriter()
        self.commandReceiver = CommandReceiver()
        setupCommandHandlers()
    }

    func setupCommandHandlers() {
        commandReceiver.registerHandler(commandType: "WriteInput") { command in
            guard let content = command["content"] as? String else {
                return false
            }
            return self.inputWriter.writeToInput(content: content)
        }

        commandReceiver.registerHandler(commandType: "ClearInput") { _ in
            return self.inputWriter.clearInput()
        }

        commandReceiver.registerHandler(commandType: "HealthCheck") { _ in
            MessageSender.sendHealthStatus(status: "ok", agentType: "macos_accessibility")
            return true
        }

        commandReceiver.registerHandler(commandType: "Stop") { _ in
            self.commandReceiver.stop()
            return true
        }
    }

    func run() {
        // 检查权限
        guard requestAccessibilityPermissions() else {
            MessageSender.sendError(message: "未授予辅助功能权限", code: "PERMISSION_DENIED")
            return
        }

        // 启动命令监听（后台线程）
        commandReceiver.startListeningAsync()

        // 启动微信监听（主线程）
        monitor.startMonitoring()

        // 运行 RunLoop
        RunLoop.main.run()
    }
}

// 启动 Agent
let agent = MacOSAgent()
agent.run()
