Java parsing XML file exercise-get app icon by app package name-other information (based on Meizu store)

1. Parse the package name data file (TXT file) and generate the package an array group:

Package Jsouphtml;import Java.io.bufferedreader;import Java.io.file;import java.io.filereader;import Java.io.ioexception;public class Getpackagename {public static string[] Getpackagename (string filename) {string Packagename[]=null; BufferedReader Istream=null; String line = null; File Packagenames = new file (filename);//"D:\\packagenames.txt" try {stringbuffer content=new stringbuffer (); iStream = New BufferedReader (New FileReader (Packagenames)), while ((Line=istream.readline ())!=null) {Content.append (Line.trim ());} Packagename=content.tostring (). Split (",");} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();} Finally{if (Istream!=null) try {istream.close ();} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();}} return packagename;}}

2, crawl data, generate icon file (based on the Meizu App Store):

Package Jsouphtml;import Java.io.file;import Java.io.fileoutputstream;import java.io.ioexception;import Java.io.inputstream;import Java.io.outputstream;import Java.net.url;import Java.net.urlconnection;import Org.jsoup.jsoup;import Org.jsoup.nodes.document;import Org.jsoup.nodes.element;import org.jsoup.select.Elements; public class Mztheme {public static void main (string[] args) {InputStream InputStream = Null;outputstream OutputStream = n ull;try {String url = "Http://app.flyme.cn/apps/public/detail?package_name="; String packagenames[] = getpackagename.getpackagename ("D:\\packagenames.txt"); System.out.println (Packagenames.length), for (int i =1;i<packagenames.length;i++) {System.out.println (i);D Ocument doc = jsoup.connect (url +packagenames[i]). get (); if (Doc.getelementsbyclass ("Mz_content mz_container clearfix" ). IsEmpty ()) {Element cElement = Doc.getelementbyid ("theme_content"); Elements IMGs = Celement.getelementsbyclass ("app_img"); String src = Imgs.first (). attr ("src"); System.out.println (SRC); System.out.println (Packagenames[i]); File icon = new file ("d:\\icons\\" + packagenames[i] + ". png");//Icon storage directory, can be modified according to the situation//1. Get URL urls u = new URL (src);//2. Open Connection URLC Onnection conn = U.openconnection ();//3. Get input stream and write out stream inputstream = Conn.getinputstream (); outputstream = new FileOutputStream (icon);//4. Write the source code to memory (set encoding) byte[] b = new Byte[2048];int len = 0;while (len = Inputstream.read (b))! =-1) {Outputstream.write (b, 0, Len);}} Else{system.out.println (packagenames[i]+ ", No_exit");}} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();} finally {//close I/otry {if (OutputStream! = N ull) Outputstream.close (); if (InputStream! = null) inputstream.close (); catch (IOException e) {e.printstacktrace ();}}}}

Generate icon file (based on app Po):

Package Jsouphtml;import Java.io.file;import Java.io.fileoutputstream;import java.io.ioexception;import Java.io.inputstream;import Java.io.outputstream;import Java.net.url;import Java.net.urlconnection;import Org.jsoup.jsoup;import Org.jsoup.nodes.document;import Org.jsoup.nodes.element;import org.jsoup.select.Elements;  public class Jsouphtml {public static void main (string[] args) {InputStream InputStream = Null;outputstream OutputStream = null;try {//string url = "http://app.flyme.cn/apps/public/detail?package_name=";//string url = "http://app.mi.com/ details?id= ";//string url =" http://www.wandoujia.com/apps/"; String url = "Http://sj.qq.com/myapp/detail.htm?apkName="; String packagenames[] = getpackagename.getpackagename ("D:\\packagenames.txt"); System.out.println (Packagenames.length), for (int i =1;i<packagenames.length;i++) {System.out.println (i);D Ocument doc = jsoup.connect (url +packagenames[i]). get (); Element content = Doc.getelementbyid ("Det-icon");//elements IMGs = doc.getelementsByclass ("app_img"); Meizu App Store//elements IMGs = Doc.getelementsbyclass ("Yellow-flower"); if (Content.isblock ()) {Elements IMGs = Doc.getelementsbytag ("img"); String src = Imgs.first (). attr ("src"); SYSTEM.OUT.PRINTLN (SRC); System.out.println (Packagenames[i]); File icon = new file ("d:\\yingyongbao\\" + packagenames[i] + ". png");//1. Get URL urls u = new URL (src);//2. Open Connection URLConnection conn = U.openconnection ();//3. Get the input stream and write out the stream inputstream = Conn.getinputstream (); outputstream = new FileOutputStream (icon)  ;//4. Write the source code to memory (set encoding) byte[] b = new Byte[2048];int len = 0;while (len = Inputstream.read (b))! =-1) {Outputstream.write (b, 0, Len);}} Else{system.out.println (packagenames[i]+ ", No_exit");}} catch (IOException e) {//TODO auto-generated catch Blocke.printstacktrace ();} finally {//close I/otry {if (OutputStream! = N ull) Outputstream.close (); if (InputStream! = null) inputstream.close ();  catch (IOException e) {e.printstacktrace ();}}} }
