[Java] 用java实现的电影天堂,飘花电影网的电影的下载地址抓取

Posted 2022-08-26 程宇寒

1.之前看了一些论坛上有一个坛友用python写的抓取电影下载链接的，于是心血来潮的我也打算用java来写一个！其实并不是很难，下面附上代码
这是对电影天堂的电影的抓取的方法，（在此期间尝试设置代过滤理，以及用线程池，但貌似均没有成功） 说明下主要的jar包主要有httpclient4.5以及jsoup1.7

1.

2.下面的飘花电影网的，其实可以看到爬取的过程是大同小异的，只是选择器有所差别而已

    public static HttpClient client=null;

    Map<Integer,String> map=new HashMap<>();
for(int i=16;i<50;i++)
  map.put(i,"http://www.piaohua.com/html/dongzuo/list_"+i+".html");

for (String string : map.values()) 
 
System.out.println("正在爬这个"+string+"网页");
        // TODO Auto-generated method stub
        getUrl(string);
     

 
   
     
public static void getUrl(String uri)
    JDBCUtils utils=new JDBCUtils();
try 
    client =HttpClientBuilder.create().build();
    HttpResponse response=client.execute(new HttpGet(uri));
    String result =EntityUtils.toString(response.getEntity(),"utf-8");
    Document doc=Jsoup.parse(result);
    doc.setBaseUri("http://www.piaohua.com");
    Elements elements=doc.select("#list dl");
    for (Element element : elements) 
        String name=element.select("font").first().text();
        String dyurl=element.select("a").first().absUrl("href");
    DyUrl dy=getDownloadUrl(name, dyurl);
    dy.setId(id);
    utils.insert(dy);
    id++;
    
 catch (IOException e) 
    // TODO Auto-generated catch block

        Elements elements=doc.select("#showinfo").select("a");
        dUrl.setDyname(name);
        dUrl.setDyUrl(elements.first().text());
     catch (IOException e) 
        // TODO Auto-generated catch block
        e.printStackTrace();
    
return dUrl;
