微信小程序嵌入腾讯视频源过程详解

首先我们有一个接口可以获取动态的vkey

https://vv.video.qq.com/getinfo?otype=json&appver=3.2.19.333&platform=11&defnpayver=1&vid=

获取的数据格式是这样的

QZOutputJson={"dltype":1,"exem":0,"fl":{"cnt":2,"fi":[{"id":100701,"name":"msd","lmt":0,"sb":1,"cname":"流畅;(180P)","br":29,"drm":0,"video":1,"fs":35776912,"sl":1},{"id":2,"name":"mp4","lmt":0,"sb":1,"cname":"高清;(480P)","br":34,"drm":0,"video":1,"fs":74129447,"sl":0}]},"hs":0,"ip":"119.137.195.73","ls":0,"preview":1186,"s":"o","sfl":{"cnt":0},"tm":1503504934,"vl":{"cnt":1,"vi":[{"br":29,"ch":0,"cl":{"fc":0,"keyid":"b0136et5ztz.100701"},"ct":21600,"drm":0,"dsb":0,"fmd5":"87d7d2ef15f55a456bcdb359dd580795","fn":"b0136et5ztz.m701.mp4","fs":35776912,"fst":5,"fvkey":"EBB1F5C7B5100A3DA80802119E3FF9D0AAE3DA6670594D507B02AD489CF21D2868B0803B76F7434CE51B5C70D75554D68ED24A49EE3DE4791E0BA58444A77756FA7CBC6FB1B3E579F44F87AFB1CB79E8522A48576A4949037A5EDC1C842A9EF7536E090EBD018BB2","head":0,"hevc":0,"iflag":0,"level":0,"lnk":"b0136et5ztz","logo":1,"mst":8,"pl":null,"share":1,"sp":0,"st":2,"tail":0,"td":"1186.92","ti":"解密潮汕多神信仰","type":3,"ul":{"ui":[{"url":"http://113.105.167.156/vhot2.qqvideo.tc.qq.com/AuRJoSSIabzpOb1RsXSviFl-nYwRDSZoFU5OpwBhfrAk/","vt":200,"dtc":0,"dt":2},{"url":"http://113.105.167.155/vhot2.qqvideo.tc.qq.com/AuRJoSSIabzpOb1RsXSviFl-nYwRDSZoFU5OpwBhfrAk/","vt":200,"dtc":0,"dt":2},{"url":"http://113.105.167.154/vhot2.qqvideo.tc.qq.com/AuRJoSSIabzpOb1RsXSviFl-nYwRDSZoFU5OpwBhfrAk/","vt":200,"dtc":0,"dt":2},{"url":"http://video.dispatch.tc.qq.com/62098754/","vt":0,"dtc":0,"dt":2}]},"vh":272,"vid":"b0136et5ztz","videotype":27,"vr":0,"vst":2,"vw":480,"wh":1.7647059,"wl":{"wi":[]}}]}};

需要的视频播放地址的格式是这样的

url + fn + '?vkey=' + fvkey

我需要的是用户可以在后台发布时候只需要复制视频链接填入即可

vedio 是腾讯播放地址例如：https://v.qq.com/x/page/c0799d0jruj.html 所以稍加改造后，代码如下

function getVideoInfo(vedio) {
 if (!vedio) return
 var vid = vedio.substring(vedio.lastIndexOf('/') + 1, vedio.lastIndexOf('html') - 1);
 var that = this;
 var urlString = 'https://vv.video.qq.com/getinfo?otype=json&appver=3.2.19.333&platform=11&defnpayver=1&vid=' + vid;
 wx.request({
  url: urlString,
  success: function (res) {
  var dataJson = res.data.replace(/QZOutputJson=/, '') + "qwe";
  var data = JSON.parse(dataJson);
  var fileName = data['vl']['vi'][0]['fn'];
  var fvkey = data['vl']['vi'][0]['fvkey'];
  var host = data['vl']['vi'][0]['ul']['ui'][2]['url']
  that.setData({
   videoUrl: host + fileName + '?vkey=' + fvkey
  });
  }
 })
 }

生成的videoUrl即是我需要的最终可以直接插入播放的视频

最后写入wxml

<view class='video'>
 <video src='{{videoUrl}}' bindplay='playVideo' id="myVideo"></video>
 <view class='tips'>建议WIFI环境下播放</view>
</view>

在小程序中使用发现需要绑定授权域名https://vv.video.qq.com 我们无法上传验证文件所以无法绑定，因为后面我在小程序接口中使用PHP方法获取视频地址

//腾讯视频获取实际播放放地址
function getVideoInfo($video){
 $vid = "";
 //正则表达式截取vid
 preg_match_all("/(?:\/page\/)(.*)(?:\.html)/i",$video, $vid);
 $vid = $vid[1][0];
 $urlString = 'https://vv.video.qq.com/getinfo?otype=json&appver=3.2.19.333&platform=11&defnpayver=1&vid='.$vid;
 $res = fopen_url($urlString);
 //字符串截取json
 $json = str_replace("QZOutputJson=","",$res);
 $json = str_replace("}}]}};","}}]}}",$json);
 //json转换为数组
 $json = json_decode($json,true);
 $fileName = $json['vl']['vi'][0]['fn'];
 $fvkey = $json['vl']['vi'][0]['fvkey'];
 $host = $json['vl']['vi'][0]['ul']['ui'][2]['url'];
 $url = $host.$fileName.'?vkey='.$fvkey;
 return $url;
}
/**
 获取远程文件内容
 @param $url 文件http地址
*/
function fopen_url($url)
{
 if (function_exists('file_get_contents')) {
  $file_content = @file_get_contents($url);
 } elseif (ini_get('allow_url_fopen') && ($file = @fopen($url, 'rb'))){
  $i = 0;
  while (!feof($file) && $i++ < 1000) {
   $file_content .= strtolower(fread($file, 4096));
  }
  fclose($file);
 } elseif (function_exists('curl_init')) {
  $curl_handle = curl_init();
  curl_setopt($curl_handle, CURLOPT_URL, $url);
  curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT,2);
  curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER,1);
  curl_setopt($curl_handle, CURLOPT_FAILONERROR,1);
  curl_setopt($curl_handle, CURLOPT_USERAGENT, 'Trackback Spam Check'); //引用垃圾邮件检查
  $file_content = curl_exec($curl_handle);
  curl_close($curl_handle);
 } else {
  $file_content = '';
 }
 return $file_content;
}

因此在小程序接口上我们使用getVideoInfo()方法来转换视频地址就行了
