微信wifi airkiss一键配网

1、微信公众号中的基本配置里面完成IP白名单配置，很重要，影响access_token

2、将下面文件下载放到目录中，只需要修改airkiss.php中的"yourAppID","yourAppSecret"，其他不变

3、代码详情
1、access_token.php

{"access_token":"","expire_time":0}

2、airkiss.php

GetSignPackage();
?>



  
  

3、jsapi_ticket.php

{"jsapi_ticket":"","expire_time":0}

4、jssdk.php

注意：MP_verify*.txt这个文件先不要，可以先跳过

5、找到设备功能进行开启

6、访问自己配置的目录http://aa.test.com/wx/airkiss.php便可以跳出

image

注意：如果此时跳出，则结束，如果还不行，可能需要JS接口安全域名配置
注意1：进入微信公众平台后台，在公众号设置->功能设置界面下配置好JS接口安全域名，如下图

此时会涉及上面下载的MP_verify*.txt文件，放到相应目录就可以，可以设置二级域名下的路径，如：aa.test.com/wx

注意2：如果需要服务器进行推送，需要创建一个index.php
