python调用通信模块flask的示例

from flask import Flask, request
import subprocess
import socket

app = Flask(__name__)

# 音频播放进程对象

@app.route('/play', methods=['POST'])
def play_audio():
    global audio_process

        return "Audio started playing."
    else:

@app.route('/stop', methods=['POST'])

        audio_process = None
        return "Audio stopped."
    else:

@app.route('/get_ip', methods=['GET'])
def get_ip():
    # 获取本机IP地址
    hostname = socket.gethostname()
    ip_address = socket.gethostbyname(hostname)
    return ip_address

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)  # 监听所有网络接口
