下载示例代码http://demo.open.weixin.qq.com/jssdk/sample.zip
解压得到
打开php文件夹里面有四个文件
先打开jssdk.php，做如下修改，修改说明请见注解
<?php
class JSSDK {private $appId;private $appSecret;public function __construct($appId, $appSecret) {$this->appId = $appId;$this->appSecret = $appSecret;}public function getSignPackage() {$jsapiTicket = $this->getJsApiTicket();// 注意 URL 一定要动态获取，不能 hardcode.$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?

}再打开sample.php文件，做如下修改
<?php
//外部引用//二维码生成http://2.weixinbuild.applinzi.com/XXX/sample.php扫码访问require_once "jssdk.php";
$jssdk = new JSSDK("appid", "secret");//分别填写appid和secret
$signPackage = $jssdk->GetSignPackage();

以上两端代码放在文件夹XXX中上传值新浪云SAE
将链接//二维码生成http://2.weixinbuild.applinzi.com/XXX/sample.php生成二维码，用微信客户端扫码后，进入页面，有对应的开始录音，停止录音，播放三个按钮，当点击开始录音后，手机同意获取权限，即可实现了录音功能，当然也可以播放。
点击微信右上角，分享给好友，你的好友收到你的分享点开就是对应的link链接。
