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
<?php exit();?>
{"access_token":"","expire_time":0}
2、airkiss.php
<?php
require_once "jssdk.php";
$jssdk = new JSSDK("yourAppID", "yourAppSecret");//这里改成自己的
$signPackage = $jssdk->GetSignPackage();
?>

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
image
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
image.png
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
<?php
define("TOKEN","echolucky");
function checkSignature()
{
//从GET参数中读取三个字段的值
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
//读取预定义的TOKEN
$token = TOKEN;
//对数组进行排序
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr, SORT_STRING);
//对三个字段进行sha1运算
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
//判断我方计算的结果是否和微信端计算的结果相符
//这样利用只有微信端和我方了解的token作对比,验证访问是否来自微信官方.
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
if(checkSignature()){
echo $_GET["echostr"];
}
else{
echo 'error';
}
