Those who want a PHP version can download the test here (link: #)
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 {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
String url = "http://v.youku.com/v_show/id_XMjU0MjI2NzY0.html";
//Get the string after the id, which is "xmju0mji2nzy0.html"
int no = url.indexOf("id_");
//Get the id value, which is "XMjU0MjI2NzY0"
String videoId = url.substring(no+3, url.indexOf(".html"));
//Gets the URL object of the video information data
URL myurl = new URL("http://v.youku.com/player/getPlayList/VideoIDS/"+videoId+"/timezone/+08/version/5/source/out?password=&ran=2513&n=3");
//Gets the input stream from the URL object
InputStreamReader isr = new InputStreamReader(myurl.openStream());
//encapsulation
BufferedReader br = new BufferedReader(isr);
//ReadLine gets the text
String urls = br.readLine();
//Close the stream
br.close();
//Get the json object
JSONObject json = JSONObject.fromObject(urls);
//Get json data (inside data)
JSONArray arr = json.getJSONArray("data");
//Get the value of the logo and print it
System.out.println(JSONObject.fromObject(arr.get(0)).get("logo"));
}
}
Another method without json, relatively white, is my first method.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
public class test1 {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
//Set video address
String url = "http://v.youku.com/v_show/id_XMjU0MjI2NzY0.html";
//Get the string after the id, which is "xmju0mji2nzy0.html"
int no = url.indexOf("id_");
//Get the id value, which is "XMjU0MjI2NzY0"
String videoId = url.substring(no+3, url.indexOf(".html"));
//Gets the URL object of the video information data
URL myurl = new URL("http://v.youku.com/player/getPlayList/VideoIDS/"+videoId+"/timezone/+08/version/5/source/out?password=&ran=2513&n=3");
//Gets the input stream from the URL object
InputStreamReader isr = new InputStreamReader(myurl.openStream());
//encapsulation
BufferedReader br = new BufferedReader(isr);
//ReadLine takes the text and then cuts the information in the text with "/"
String[] urls = br.readLine().split("\/");
isr.close();
br.close();
//Because the information data is in a fixed format, the direct fourth element must be what we need.
String target = urls[3];
//Continue to "cut" the above results
String imgid = target.substring(0,target.indexOf("""));
//Piece it together and it's the address we need
String img = "http://g2.ykimg.com/" + imgid;
System.out.println(img);
/*
The result is: http://g2.ykimg.com/1100641F464D8FBF5FA3D90209C8DF96B67E2C-567E-AB53-C132-D7787FC966AB
