想要php版的朋友可以到這里下載測(cè)試 //www.conghuacea.com/codes/83179.html

import java.io.BufferedReader;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.net.MalformedURLException;
 import java.net.URL;
 import net.sf.json.*;

public class test2 {
    /**
     * @param args
     * @throws IOException 
     */
    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        String url = "http://v.youku.com/v_show/id_XMjU0MjI2NzY0.html";
        //獲取id后面的字符串，也就是"XMjU0MjI2NzY0.html"
        int no = url.indexOf("id_");
        //獲取id值，也就是"XMjU0MjI2NzY0"
        String videoId = url.substring(no+3, url.indexOf(".html"));
        //獲取視頻信息數(shù)據(jù)的URL對(duì)象
        URL myurl = new URL("http://v.youku.com/player/getPlayList/VideoIDS/"+videoId+"/timezone/+08/version/5/source/out?password=&ran=2513&n=3");
　　
        //從URL對(duì)象中獲取輸入流
        InputStreamReader isr = new InputStreamReader(myurl.openStream());
        //封裝
        BufferedReader br = new BufferedReader(isr);
        //readLine獲取文本
        String urls = br.readLine();
        //關(guān)閉流
        br.close();
        //獲取json對(duì)象
        JSONObject json = JSONObject.fromObject(urls);
        //獲取json數(shù)據(jù)（data內(nèi)）
        JSONArray arr = json.getJSONArray("data");
        //獲取logo的值并打印
        System.out.println(JSONObject.fromObject(arr.get(0)).get("logo"));
    }
}

另一種沒(méi)有用json的方案，比較小白，也是本人第一次的方法。

復(fù)制代碼代碼如下:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class test1 {
    /**
     * @param args
     * @throws IOException
     */
    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        //設(shè)定視頻地址
        String url = "http://v.youku.com/v_show/id_XMjU0MjI2NzY0.html";
        //獲取id后面的字符串，也就是"XMjU0MjI2NzY0.html"
        int no = url.indexOf("id_");
        //獲取id值，也就是"XMjU0MjI2NzY0"
        String videoId = url.substring(no+3, url.indexOf(".html"));
        //獲取視頻信息數(shù)據(jù)的URL對(duì)象
        URL myurl = new URL("http://v.youku.com/player/getPlayList/VideoIDS/"+videoId+"/timezone/+08/version/5/source/out?password=&ran=2513&n=3");
        //從URL對(duì)象中獲取輸入流
        InputStreamReader isr = new InputStreamReader(myurl.openStream());
        //封裝
        BufferedReader br = new BufferedReader(isr);
        //readLine獲取文本，然后以"http://"切割文本中的信息
        String[] urls = br.readLine().split("http:///");
        isr.close();
        br.close();
        //因?yàn)樾畔?shù)據(jù)是固定格式的，所以直接第四個(gè)元素肯定是我們所需要的。
        String target = urls[3];
        //對(duì)上面結(jié)果繼續(xù)以"切割
        String imgid = target.substring(0,target.indexOf("/""));
        //拼湊一下，就是我們需要的地址了
        String img = "http://g2.ykimg.com/" + imgid;
        System.out.println(img);
        /*
         結(jié)果為：http://g2.ykimg.com/1100641F464D8FBF5FA3D90209C8DF96B67E2C-567E-AB53-C132-D7787FC966AB
         */
    }
