JS调用Python控制WIFI

** 最近遇到的一个需求，需要通过连接wifi判断是否路由器可用。**

python服务端：

import subprocess as sp
    import logging
    import subprocess as sp
    import time
    
    import pywifi
    from flask import Flask, make_response, jsonify
    from flask_cors import CORS
    from pywifi import const
    
    global data
    
    app = Flask(__name__)
    logger = logging.getLogger(__name__)
    logger.error("time:{}".format(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())))
    try:
        # w:覆盖式写入
        # a:追加式写入
        with open('test.txt', 'w', encoding='utf-8', errors='ignore') as f:
            f.write(str(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())))
    except:
        pass
    
    
    @app.route("/")
    def index():
        # 路由器
        bool = connect_wifi_password("wwbnqdfg_5G", "zzfXXXXXXX")
        data=''
        if (bool == True):
            status, result = sp.getstatusoutput("ping " + "www.baidu.com")
            if status == 1:
                data = "false"
            else:
                data = "true"
        else:
            data = "false"
        # 连接回原wifi了
        connect_wifi_password("wwbnqdfg_5G", "zzfXXXXXXX")
        result_text = {"statusCode": 200, "message": data}
        response = make_response(jsonify(result_text))
        response.headers['Access-Control-Allow-Origin'] = '*'
        response.headers['Access-Control-Allow-Methods'] = 'OPTIONS,HEAD,GET,POST'
        response.headers['Access-Control-Allow-Headers'] = 'x-requested-with'
        return response
    
    
    def connect_wifi_password(wifiName, password):
        wifi = pywifi.PyWiFi()  # 创建一个wifi对象
        ifaces = wifi.interfaces()[0]  # 取第一个无限网卡
        ifaces.disconnect()  # 断开网卡连接
        time.sleep(3)  # 缓冲3秒
    
        profile = pywifi.Profile()  # 配置文件
        profile.ssid = wifiName  # wifi名称
        profile.auth = const.AUTH_ALG_OPEN  # 需要密码
        profile.akm.append(const.AKM_TYPE_WPA2PSK)  # 加密类型
        profile.cipher = const.CIPHER_TYPE_CCMP  # 加密单元
        profile.key = password  # wifi密码
    
        ifaces.remove_all_network_profiles()  # 删除其他配置文件
        tmp_profile = ifaces.add_network_profile(profile)  # 加载配置文件
    
        ifaces.connect(tmp_profile)  # 连接
        time.sleep(5)  # 尝试10秒能否成功连接
        isok = True
        if ifaces.status() == const.IFACE_CONNECTED:
            print("成功连接")
        else:
            print("失败")
            isok = False
        time.sleep(1)
        return isok
    
    
    if __name__ == "__main__":
        app.run(host='127.0.0.1', threaded=True, debug=True)
        CORS(app)

Js调用方式：

$.ajax({
    					url: 'http://localhost:5000/',
    					type: 'get',
    					success: function(data) {
    	                    if(data["message"] == "true") {
                                …… //wifi可用    
                            }
    
    					},
    					error: function(error) {
                                ……
    					}
    				});

这里可以用bat文件启动这个py脚本，这样就能通过接口的方式去判断当前wifi路由器是否可用……
