网络视频源地址抓包分析（3）之获取腾讯视频源码

有朋友问我如何获取网络腾讯的网络视频，今天翻了一下3年前写的代码，发现还能用，但没有太多注释，凑合看吧。获取的网络视频地址无任何广告，为CDN最后返回的结果，可直接播放或下载。有些视频过大，CDN有分段处理，如果多段以“$”隔开。今天只对获取腾讯网络视频进行了整理，实际上各大网络视频获取方式都一样，只要分析下请求链接与参数，然后模拟请求整理成代码即可。

 这东西只要有一点编程基础，在加一点分析能力就可分析出来。

 JAVA代码如下：（MAIN方法直接可以运行）

import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class TX {

	public String getTencentMovieSource(String url) {
		String html = this.getHtml(url, true).replaceAll("	", "");
		String vid = this.getValue(html, "vid:", 1, "\",", 0);
		String urlXml = "http://vv.video.qq.com/geturl?platform=1&otype=xml&vid=" + vid;
		if(urlXml.indexOf("|") == -1)
			return this.parseXmlSource(urlXml);
		else{
			String urls = "";
			String [] uls = urlXml.replace("|", "-").split("-");
			for (int i = 0; i < uls.length; i++){
				String htmls = "http://vv.video.qq.com/geturl?platform=1&otype=xml&vid=" + uls[i];
				urls += this.parseXmlSource(htmls) + "$";
			}
			return urls.substring(0,urls.lastIndexOf("$"));
		}
	}
	
	private String parseXmlSource(String urlXml){
		String videoXml = getHtml(urlXml, false);
		return getValue(videoXml, "", "");
	}
	
	private String getHtml(String url , boolean isformat){
		System.out.println("Request URL:"+url);
		try{
			URL u = new URL(url);
			HttpURLConnection httpConn = (HttpURLConnection) u.openConnection();
			//设置user agent确保系统与浏览器版本兼容
			HttpURLConnection.setFollowRedirects(true);
		    httpConn.setRequestMethod("GET"); 
		    httpConn.setRequestProperty("User-Agent","Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727)");
			InputStream is = u.openStream();
			int length = 0;
			ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
	        while((length=is.read()) != -1) { 
	        	 bos.write(length);
	        }
			if(isformat)
				return new String(bos.toByteArray(),"UTF-8").replace("\r", "").replace("\n", "");
			else
				return new String(bos.toByteArray(),"UTF-8");
		}catch(Exception e){
			e.printStackTrace();
			return null;
		}
	}
	
	private String getValue(String html ,String s1,String s2){
		try{
			String subHtml = html.substring(html.indexOf(s1));
			subHtml = subHtml.substring(s1.length());
			int s2Len = subHtml.indexOf(s2);
			return String.valueOf(subHtml.substring(0,s2Len));
		}catch(Exception e){
			e.printStackTrace();
			return null;
		}
	}
		
	private String getValue(String html , String s1 ,int s1length , String s2 , int s2length){
		try{
			StringBuffer subHtml = new StringBuffer(html.substring(html.indexOf(s1)));
			return String.valueOf(subHtml.substring(s1.length() + s1length , subHtml.indexOf(s2) - s2length));
		}catch(Exception e){
			e.printStackTrace();
			return null;
		}
	}
	
	public static void main(String[] args) {
		String s = new TX().getTencentMovieSource("http://v.qq.com/cover/y/y1xpnck2llvs7wa.html");
		System.out.println("视频源地址:"+s);
	}
}

通过main方法，传入视频页面地址参数，直接运行即可。

 

 其它网络视频获取也有些代码，欢迎交流！
