This article mainly introduces in detail the temporary conversion of WeChat recordings to permanent storage developed by PHP WeChat. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

I encountered this problem recently during development. Party A hopes that the user's recording on WeChat will always be valid. Just open your friend's sharing at any time and you can listen to your friend's recording. It can be found in the WeChat official development manual that the WeChat recording file can only be retained on WeChat for 3 days after being uploaded, and it will become invalid after 3 days. How to do it?

1. Download the WeChat recording to the local by calling the WeChat media resource download interface


@params String access_token 微信公众号access_token String serverId 通过录音上传接口获取到的serverId http://file.api.weixin.qq.com/cgi-bin/media/get?access_token={$access_token}&media_id={$serverId}
Copy after login

2. Download the recording from the WeChat side to the local The file format is amr, and the WeChat web browser does not support audio file playback of amr files. So we need to convert amr into mp3 format that
web pages can recognize.

How to convert? I found a platform that can support this conversion, Qiniu Cloud Storage Platform. Through Qiniu Cloud Storage we can convert amr to mp3


require("./extension/autoload.php");//官方开发包 可在官方下载 php版本 载入其中的autoload.php extension 是随意 起的名字 /** * @param * String $filepa 本地amr文件路径 * @return * String 解析后存储在七牛存储空间中的mp3远程地址 */ function upchange($filepa){ $accessKey="七牛accessKey 在七牛后台获取"; $secretKey="七牛secretKey 在七牛后台获取"; $httpUrl ="七牛分配的访问地址 在七牛后台获取"; $bucket = "存储空间对象bucket 在七牛后台创建"; //转码时使用的队列名称 $pipeline = '转码队列名称 在七牛后台创建'; $auth = new \Qiniu\Auth($accessKey, $secretKey); $rand_name = getRandChar__(6).time().'.mp3'; //要进行转码的转码操作 $fops = "avthumb/mp3/ab/64k/ar/22050"; //$fops = "mp3"; //可以对转码后的文件进行使用saveas参数自定义命名,当然也可以不指定文件会默认命名并保存在当间 $savekey = Qiniu\base64_urlSafeEncode('kepei:'.$rand_name); $fops = $fops.'|saveas/'.$savekey; $policy = array( 'persistentOps' => $fops, 'persistentNotifyUrl' => 'http://', ); $uptoken = $auth->uploadToken($bucket, null, 3600, $policy); //上传文件的本地路径 $filePath = $filepa; $key = $rand_name; //$key = ''; $uploadMgr = new \Qiniu\Storage\UploadManager(); list($ret, $err) = $uploadMgr->putFile($uptoken, $key, $filePath); if ($err !== null) { return false; } else { return $httpUrl.$rand_name; } } function getRandChar__($length){ $str = null; $strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz"; $max = strlen($strPol)-1; for($i=0;$i<$length;$i++){ $str.=$strPol[rand(0,$max)];//rand($min,$max)生成介于min和max两个数之间的一个随机整数 } return $str; } $amrToMp3 = upchange('本地amr文件路径'); //mp3 在七牛上的访问地址 var_dump($amrToMp3); /** * 如果你希望将这个mp3 存储在本地而不是在七牛上,那么你需要在程序上等待几秒,因为这时七牛在转换改amr的格式 */ sleep(10); $res = curlHttp($amrToMp3); //curlHttp 就是 php curl 机制 不懂的可以看下我下面文章机制 $open = fopen('demo.mp3','w'); fwrite($open,$res); fclose($open);
Copy after login
