1. 无法直接浏览器 ping ？试试这个！

适用：无法利用路由器的手机端等。

import subprocess
import platform

while True:
    ip = input("\n请输入IP地址（输入q退出）：").strip()
    if ip.lower() == 'q':
        break
    if not ip:
        continue
    
    param = '-n' if platform.system().lower() == 'windows' else '-c'
    print(f"正在测试 {ip} ...")
    
    try:
        result = subprocess.run(['ping', param, '1', ip], 
                              capture_output=True, text=True, timeout=5)
        if result.returncode == 0:
            print(f"✅ {ip} 在线")
        else:
            print(f"❌ {ip} 离线或超时")
    except Exception as e:
        print(f"❌ 出错: {e}")

2.可以用？那就这个！

适用：可以使用浏览器的设备及环境。

from http.server import HTTPServer, BaseHTTPRequestHandler
import subprocess
import platform
import urllib.parse

class PingHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        if self.path.startswith('/ping'):
            # 解析URL参数
            parsed = urllib.parse.urlparse(self.path)
            params = urllib.parse.parse_qs(parsed.query)
            ip = params.get('ip', [''])[0]
            
            # 简单校验IP格式（防注入）
            if not ip or not ip.replace('.','').replace(':','').isalnum():
                self.send_response(200)
                self.send_header('Content-type', 'text/html')
                self.end_headers()
                self.wfile.write('<h3>错误：无效IP地址</h3>'.encode('utf-8'))
                return
            
            # 执行ping命令
            param = '-n' if platform.system().lower() == 'windows' else '-c'
            try:
                result = subprocess.run(['ping', param, '4', ip], 
                                      capture_output=True, text=True, timeout=10)
                if result.returncode == 0:
                    status = f'✅ {ip} 在线'
                    detail = result.stdout
                else:
                    status = f'❌ {ip} 离线或超时'
                    detail = result.stderr or result.stdout
            except Exception as e:
                status = '❌ 执行出错'
                detail = str(e)
            
            # 返回HTML结果
            html = f'''
            <html>
            <body>
                <h2>{status}</h2>
                <pre>{detail}</pre>
                <a href="/">← 返回</a>
            </body>
            </html>
            '''
            self.send_response(200)
            self.send_header('Content-type', 'text/html')
            self.end_headers()
            self.wfile.write(html.encode('utf-8'))
        else:
            # 返回输入界面
            html = '''
            <html>
            <body>
                <h2>Ping工具</h2>
                <form action="/ping" method="get">
                    <input type="text" name="ip" placeholder="输入IP地址，如 192.168.1.1">
                    <button type="submit">Ping</button>
                </form>
            </body>
            </html>
            '''
            self.send_response(200)
            self.send_header('Content-type', 'text/html')
            self.end_headers()
            self.wfile.write(html.encode('utf-8'))

if __name__ == '__main__':
    print('服务器启动在 http://localhost:8000')
    server = HTTPServer(('', 8000), PingHandler)
    server.serve_forever()
