我们分两种情况介绍网易新闻手机端视频的地址解析：
- 单独视频播放页
- 含有视频的富媒体页
单独视频播放页
以播放页 http://c.m.163.com/news/v/VC3A7L2UU.html 为例说说如何得到视频的真实地址。
其实，视频真实地址就在页面源代码中：
<article class="m-video-player"><div class="video-holder"><div class="video-wrap js-video">
<video src="http://flv2.bn.netease.com/videolib3/1610/25/wnjIA1492/SD/wnjIA1492-mobile.mp4" type="video/mp4" webkit-playsinline="true" controls preload="none"></video>
...
</article>
video元素的src属性值即为视频的真实地址。
Python代码示例：
import requests
from pyquery import PyQuery as pq
headers = {'User-Agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36',}
r = requests.get('http://c.m.163.com/news/v/VC3A7L2UU.html', headers=headers)
d = pq(r.content)
print d('video').attr('src')
注意，代码示例中在请求手机端页面的时候加上了手机浏览器的User-Agent请求头。
含有视频的富媒体页
以富媒体页面 http://c.m.163.com/news/a/C42K63S1000181N1.html 为例说说如何得到视频的真实地址。
这次没有那么幸运了，页面源码中并没有视频地址。当使用桌面浏览器打开页面并且点击“视频播放器”打算播放的时候，页面跳转了，提示我们下载网易新闻APP观看。那只好在手机端抓包分析了。我在安卓模拟器中用浏览器打开页面，同时使用Wireshark捕捉HTTP数据包，并对抓到的数据包逐一分析，发现了如下接口请求：
http://c.m.163.com/nc/article/C42K63S1000181N1/full.html
该请求地址中的C42K63S1000181N1即为富媒体页面地址的一部分。
请求该接口返回的JSON数据如下：
{
"C42K63S1000181N1": {

在上面的JSON数据中，video列表里面包含的就是视频的真实地址了。其中，mp4Hd_url是高清地址，mp4_url是标清地址，这两个地址中可能有一个不存在。
至此，Python代码示例如下：
import re
import json
import requests
headers = {'User-Agent': 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36',}
m = re.search(r'/(\w+).html', 'http://c.m.163.com/news/a/C42K63S1000181N1.html')
doc_id = m.groups()[0]
api_url = 'http://c.m.163.com/nc/article/%s/full.html' % doc_id
r = requests.get(api_url, headers=headers)
data = json.loads(r.content)
videos = data[doc_id]['video']
for video in videos:
print video.get('mp4Hd_url')
print video.get('mp4_url')
