开始入门

兼容性

@capgo/capacitor-device-info 需要 Capacitor 8 或更高版本（@capacitor/core >=8.0.0).

安装

您可以使用我们的 AI 助手来安装插件。使用以下命令将 Capgo 技能添加到您的 AI 工具中：

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下提示:

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-device-info` plugin in my project.

对于手动设置，请安装包并同步本机项目：

npm install @capgo/capacitor-device-info
npx cap sync

导入

import { DeviceInfo } from '@capgo/capacitor-device-info';

读取一个快照

const snapshot = await DeviceInfo.getInfo();

console.log(snapshot.cpu.cores);
console.log(snapshot.memory.usedPercent);
console.log(snapshot.storage.freeBytes);
console.log(snapshot.sensors?.pressureHpa);

cpu.usagePercent 基于差异的。第一个本机样本可以省略它；调用 getInfo() 稍后再试或使用监控接收第二个样本后的填充CPU使用率。

实时更新

const handle = await DeviceInfo.addListener('deviceInfoUpdate', (sample) => {
  console.log(sample.sequence, sample.elapsedMs);
  console.log(sample.cpu.usagePercent);
  console.log(sample.sensors?.readings);
});

const session = await DeviceInfo.startMonitoring({
  intervalMs: 1000,
  emitImmediately: true,
});

console.log(session.intervalMs, session.startedAt);

监控行为

• intervalMs 默认为 1000 毫秒。小于 250 毫秒将被限制为 250.
• emitImmediately 默认为 true.
• 设置 durationMs 或 sampleCount 自动停止监控.
• 调用 startMonitoring() 监控期间重新启动会使用新的选项重启会话.
• 每个 deviceInfoUpdate 包含一个基于1的 sequence会话的 startedAt 时间戳，和 elapsedMs.

停止更新并移除监听器

await DeviceInfo.stopMonitoring();
await handle.remove();

// Or remove every listener registered on this plugin:
await DeviceInfo.removeAllListeners();

检查监控状态

const state = await DeviceInfo.isMonitoring();

if (state.monitoring) {
  console.log(state.samplesEmitted);
}

设备感知字段

const { sensors, cpu, gpu } = await DeviceInfo.getInfo();

console.log(cpu.temperatureCelsius);
console.log(gpu?.temperatureCelsius);
console.log(sensors?.batteryTemperatureCelsius);
console.log(sensors?.ambientTemperatureCelsius);
console.log(sensors?.relativeHumidityPercent);
console.log(sensors?.pressureHpa);
console.log(sensors?.illuminanceLux);
console.log(sensors?.proximityDistanceCm);
console.log(sensors?.availableSensors);

设备感知字段是可选的。它们仅在设备、操作系统和应用程序沙盒暴露该指标时才会出现。

平台说明

• iOS 不需要权限来暴露指标。它报告了 CoreMotion 感知器的可用性，但不报告原始 CPU 或 GPU 温度。
• Android 不需要权限来暴露指标。CPU 和 GPU 温度是最佳努力的热区读取。
• Web 支持是最佳努力，并报告空的设备感知字段数组，因为浏览器不一致地暴露本机设备感知器。

API 参考

Method	Returns	Notes
getInfo()	Promise<DeviceInfoSnapshot>	Reads one snapshot.
startMonitoring(options?)	Promise<StartMonitoringResult>	Starts periodic snapshots, or restarts an active session with new options.
stopMonitoring()	Promise<StopMonitoringResult>	Stops the active session.
isMonitoring()	Promise<MonitoringState>	Returns current session state.
addListener('deviceInfoUpdate', listener)	Promise<PluginListenerHandle>	Registers a periodic snapshot listener.
removeAllListeners()	Promise<void>	Removes every listener registered on the plugin.
getPluginVersion()	Promise<PluginVersionResult>	Reads the native plugin version.

PluginListenerHandle is provided by Capacitor and has remove() for removing that individual listener.

interface CpuInfo {
  cores: number;
  activeCores?: number;
  architecture?: string;
  model?: string;
  usagePercent?: number | null;
  maxFrequencyHz?: number;
  temperatureCelsius?: number;
}

interface MemoryInfo {
  totalBytes?: number;
  freeBytes?: number;

interface StorageInfo {
  totalBytes?: number;
  freeBytes?: number;
  usedBytes?: number;
  usedPercent?: number;
}

interface GpuInfo {
  api?: 'metal' | 'opengl' | 'webgl' | 'unknown';
  vendor?: string;
  renderer?: string;
  version?: string;
  maxTextureSize?: number;

type ThermalState = 'nominal' | 'fair' | 'serious' | 'critical' | 'unknown';

interface DeviceInfoSnapshot {
  timestamp: number;
  platform: 'ios' | 'android' | 'web';
  cpu: CpuInfo;
  memory: MemoryInfo;
  storage: StorageInfo;
  gpu?: GpuInfo;
  thermalState?: ThermalState;
  lowPowerMode?: boolean;
  sensors?: OnboardSensorsInfo;
}

大小以字节为单位， maxFrequencyHz 是赫兹，温度值以摄氏度为单位。 usagePercent 可以 null 直到平台有足够的样本来计算它。

传感器类型

interface OnboardSensorDescriptor {
  type: string;
  name?: string;
  vendor?: string;
  platformType?: number;
  maximumRange?: number;
  resolution?: number;
  powerMilliamp?: number;
  minDelayMicroseconds?: number;
  wakeUp?: boolean;
}

interface OnboardSensorReading {
  type: string;
  unit: string;
  value: number;
  name?: string;
  timestamp?: number;
}

interface OnboardSensorsInfo {
  availableSensors?: OnboardSensorDescriptor[];
  readings?: OnboardSensorReading[];
  batteryTemperatureCelsius?: number;
  ambientTemperatureCelsius?: number;
  relativeHumidityPercent?: number;
  pressureHpa?: number;
  illuminanceLux?: number;
  proximityDistanceCm?: number;
}

传感器读数的时间戳以Unix时间戳毫秒为单位。常见单位包括摄氏度，百分比，百帕，光度和厘米。

监控类型

interface MonitoringOptions {
  intervalMs?: number;
  durationMs?: number;
  sampleCount?: number;
  emitImmediately?: boolean;

interface StartMonitoringResult {
  monitoring: boolean;
  intervalMs: number;
  startedAt: number;

interface StopMonitoringResult {
  monitoring: boolean;

}

interface DeviceInfoUpdate extends DeviceInfoSnapshot {
  sequence: number;
  startedAt: number;
  elapsedMs: number;
}

interface PluginVersionResult {
  version: string;
}

startedAt, timestamp，和 elapsedMs 是毫秒。 sequence 从每个监控会话开始 1 的源真实性
