这篇文章主要介绍了java获取百度网盘真实下载链接的方法,涉及java针对URL操作及页面分析的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了java获取百度网盘真实下载链接的方法。分享给大家供大家参考。具体如下:
目前还存在一个问题,同一ip在获取3次以后会出现验证码,会获取失败,感兴趣的朋友对此可以加以完善。
返回的List<Map<String, Object>> 中的map包含:fileName( 文件名),url(实链地址)
HttpRequest.java如下:
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.RandomAccessFile; import java.lang.reflect.Method; import java.net.HttpURLConnection; import java.net.URL; public class HttpRequest { public static String getData(String u) throws Exception { String re=""; URL url = new URL(u); HttpURLConnection httpURLConnection = (HttpURLConnection) url .openConnection(); httpURLConnection.setRequestMethod("GET"); httpURLConnection.setDoInput(true); httpURLConnection.setDoOutput(true); InputStream is = httpURLConnection.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader bufferedReader = new BufferedReader(isr); String iL = ""; while ((iL = bufferedReader.readLine()) != null) { re += iL + "\n"; } return re; } }
获取方法:
import java.net.URLEncoder; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import org.json.JSONArray; import org.json.JSONObject; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; public class BaiduNetDisk { public static List<Map<String, Object>> getUrl(String url) throws Exception { List<String> fs_id = new ArrayList<String>(); List<Map<String, Object>> list = new ArrayList<Map<String, Object>>(); Document doc = Jsoup.connect(url).get(); String html = doc.toString(); int a = html.indexOf("{\"typicalPath"); int b = html.indexOf("yunData.getCon"); int sign_head = html.indexOf("yunData.SIGN = \""); int sign_foot = html.indexOf("yunData.TIMESTAMP"); int time_head = html.indexOf("yunData.TIMESTAMP = \""); int time_foot = html.indexOf("yunData.SHARE_UK"); int share_id_head = html.indexOf("yunData.SHARE_ID = \""); int share_id_foot = html.indexOf("yunData.SIGN "); String sign = html.substring(sign_head, sign_foot); sign = sign.substring(sign.indexOf("\"") + 1, sign.indexOf("\";")); String time = html.substring(time_head, time_foot); time = time.substring(time.indexOf("\"") + 1, time.indexOf("\";")); String share_id = html.substring(share_id_head, share_id_foot); share_id = share_id.substring(share_id.indexOf("\"") + 1, share_id.indexOf("\";")); System.out.println(share_id); html = html.substring(a, b); a = html.indexOf("{\"typicalPath"); b = html.indexOf("};"); JSONArray jsonArray = new JSONArray("[" + html.substring(a, b + 1) + "]"); JSONObject jsonObject = jsonArray.getJSONObject(0); String uk = jsonObject.getString("uk"); String shareid = jsonObject.getString("shareid"); String path = URLEncoder.encode(jsonObject.getString("typicalPath"), "utf-8"); jsonArray = new JSONArray("[" + jsonObject.getString("file_list") + "]"); jsonObject = jsonArray.getJSONObject(0); jsonArray = new JSONArray(jsonObject.getString("list")); jsonObject = jsonArray.getJSONObject(0); String app_id = jsonObject.getString("app_id"); if (jsonObject.getString("isdir").equals("1")) { String url1 = "http://pan.baidu.com/share/list?uk=" + uk + "&shareid=" + shareid + "&page=1&num=100&dir=" + path + "&order=time&desc=1&_=" + time + "&bdstoken=c51077ce0e0e313a16066612a13fbcd4&channel=chunlei&clienttype=0&web=1&app_id=" + app_id; String fileListJson = HttpRequest.getData(url1); System.out.println(fileListJson); jsonArray = new JSONArray("[" + fileListJson + "]"); jsonObject = jsonArray.getJSONObject(0); jsonArray = new JSONArray(jsonObject.getString("list")); } final int size = jsonArray.length(); for (int i = 0; i < size; i++) { Map<String, Object> map = new HashMap<String, Object>(); jsonObject = jsonArray.getJSONObject(i); String fileName = jsonObject.getString("server_filename"); map.put("fileName", fileName); fs_id.add(jsonObject.getString("fs_id")); String fileInfo = HttpRequest .getData("http://pan.baidu.com/api/sharedownload?sign=" + sign + "×tamp=" + time + "&bdstoken=c51077ce0e0e313a16066612a13fbcd4&channel=chunlei&clienttype=0&web=1&app_id=250528&encrypt=0&product=share&uk=" + uk + "&primaryid=" + share_id + "&fid_list=%5B" + fs_id.get(i) + "%5D"); JSONArray jsonArray2 = new JSONArray("[" + fileInfo + "]"); JSONObject json_data = jsonArray2.getJSONObject(0); if (json_data.getString("errno").equals("0")) { jsonArray2 = new JSONArray(json_data.getString("list")); json_data = jsonArray2.getJSONObject(0); map.put("url", json_data.getString("dlink")); } else if (json_data.getString("errno").equals("-20")) { return null; // String getVerCode(); } else { return null; } list.add(map); } return list; } }
希望本文所述对大家的java程序设计有所帮助。
