REM 用于外部监控服务状态

REM 检查心跳文件是否存在
if not exist "%HEARTBEAT_FILE%" (
    echo [错误] 心跳文件不存在: %HEARTBEAT_FILE%
    echo [错误] 服务可能未启动或已宕机
    goto :SEND_ALERT
)

echo [信息] 心跳文件: %HEARTBEAT_FILE%

REM 读取心跳文件内容
for /f "delims=" %%i in ('powershell -Command "Get-Content '%HEARTBEAT_FILE%' | ConvertFrom-Json | Select-Object -ExpandProperty last_heartbeat"') do (
    set "LAST_HEARTBEAT=%%i"
)

if "!LAST_HEARTBEAT!"=="" (
    echo [错误] 无法读取心跳信息
    goto :SEND_ALERT
)

echo [信息] 上次心跳: !LAST_HEARTBEAT!

REM 计算时间差（使用PowerShell）
for /f %%i in ('powershell -Command "$now=[DateTime]::Now; $last=[DateTime]::Parse('!LAST_HEARTBEAT!'); ($now - $last).TotalSeconds"') do (
    set "TIME_DIFF=%%i"
)

REM 去除小数点
for /f "tokens=1 delims=." %%a in ("!TIME_DIFF!") do set "TIME_DIFF_INT=%%a"

echo [信息] 距离上次心跳: !TIME_DIFF_INT! 秒

REM 检查是否超时
if !TIME_DIFF_INT! GTR %CHECK_INTERVAL% (
    echo [错误] 服务可能已宕机（超过%CHECK_INTERVAL%秒未更新心跳）
    goto :SEND_ALERT
)

echo [信息] 服务运行正常
echo.

echo 检查完成 - 状态正常

echo.
echo [警告] 检测到服务异常，正在发送通知...

REM 发送宕机通知
cd /d %~dp0
go run test_service_alert.go

if %ERRORLEVEL% EQU 0 (
    echo [信息] 宕机通知发送成功
) else (
    echo [错误] 宕机通知发送失败
)
