首先我們有一個接口可以獲取動態的vkey

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

獲取的數據格式是這樣的

QZOutputJson={"dltype":1,"exem":0,"fl":{"cnt":2,"fi":[{"id":100701,"name":"msd","lmt":0,"sb":1,"cname":"流暢;(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":[]}}]}};

需要的視頻播放地址的格式是這樣的

url + fn + '?vkey=' + fvkey

我需要的是用戶可以在后臺發布時候只需要復制視頻鏈接填入即可

vedio 是騰訊播放地址例如：https://v.qq.com/x/page/c0799d0jruj.html  所以稍加改造后，代碼如下

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即是我需要的最終可以直接插入播放的視頻

最后寫入wxml

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