以虎牙视频播放页地址 [http://v.huya.com/play/3474405.html][http_v.huya.com_play_3474405.html] 为例，说说如何得到视频的真实地址。

## 提取视频ID ##

视频ID（vid）可以从播放页地址中得到，上述播放页地址对应的视频ID就是3474405.

## 请求接口 ##

通过浏览器开发者工具的网络监测，我们发现如下接口：

http://playapi.v.duowan.com/index.php?r=play%2Fvideo&vid=3474405&partner=

请求该接口返回的是JSON格式数据：

items列表中包含了各个清晰度视频的相关信息。可以看到，共有原画、流畅、高清和超清这4种码流。每种码流中的urls就是视频的真实地址。

## Python代码示例 ##

import requests
    import json
    import re
    import random
    
    vid = re.search(r'/play/(.*).html', 'http://v.huya.com/play/3474405.html').group(1)
    play_api = 'http://playapi.v.duowan.com/index.php?partner=&r=play/video&vid=%s' % vid
    r = requests.get(play_api)
    data = json.loads(r.content)
    for item in data['result']['items']:
        definition = item['task_name']
        urls = item['transcode']['urls']
        print definition
        print random.choice(urls)

运行结果：
