在windows中直接使用nginx调试程序，增加一个脚本控制程序。

title Nginx Management Ultimate Script (Windows)

:: Force set variables with quotes, avoid empty value issues
set "NGINX_EXE=nginx.exe"
set "USER_CHOICE="

:: Step 1: Check nginx.exe existence (compatible with all paths)
if not exist "%NGINX_EXE%" (
    echo Error: %NGINX_EXE% not found in current directory!
    echo Please put this script in Nginx root folder.
    pause
    exit /b 1
)

:: Core loop (menu auto return)
:MENU_LOOP
cls

:: Step 2: List current Nginx processes (stable command)
echo ==============================================
echo          Current Nginx Processes
echo ==============================================
tasklist /fi "IMAGENAME eq %NGINX_EXE%" 2>nul
if %ERRORLEVEL% EQU 1 (
    echo No running Nginx processes found.
)
echo ==============================================
echo.

:: Step 3: Display menu (no truncated text, no special characters)
echo          Nginx Management Menu
echo ==============================================
echo  1. Start Nginx (Pre-check)
echo  2. Stop Nginx (Pre-check)
echo  3. Restart Nginx (Stop + Start)
echo  0. Exit Script
echo ==============================================

:: Step 4: Get user input (force clear previous value, avoid residual)
set "USER_CHOICE="
set /p "USER_CHOICE=Please enter number (0-3): "

:: Step 5: Operation logic (USE GOTO INSTEAD OF IF/ELSE IF - core fix for parsing error)
:: This avoids the nested if/else if parsing conflict that causes ". was unexpected"
