用java实现新浪爬虫,代码完整剖析(仅针对当前SinaSignOn有效)
先来看我们的web.xml文件，如下
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app>
<display-name>MySinaSpider</display-name>
<listener>
<listener-class>main.java.sina.spider.StartSpiderLisenter</listener-class>
</listener>
</web-app>
这样的配置当启动tomcat的时候，就会运行爬虫，然后再看我们的StartSpiderLisenter类，如下
package main.java.sina.spider; import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import main.java.sina.bean.info.LoginInfo;
import main.java.sina.utils.Constant; public class StartSpiderLisenter implements ServletContextListener{ public void contextDestroyed(ServletContextEvent arg0) { } public void contextInitialized(ServletContextEvent arg0) {
Constant.personalHomePage = "http://weibo.com/zhaoyao2012/home"; //填写你自己的新浪微博个人主页
LoginInfo.username = "***"; //填写你的新浪微博用户名
LoginInfo.password = "***"; //填写你的新浪微博密码
Constant.enableProxy = false; //是否使用代理
Spider.start();
} }
很明显我们看到StartSpiderLisenter 类是继承自ServletContextListener这个接口，一定要实现它的两个方法，contextInitialized和contextDestroyed.它们分别在初始化和销毁的时候被容器调用。我们看到在contextInitialized初始化上下文的方法中调用了Spider.start()方法。那么我们来看看Spider这个类，如下：
package main.java.sina.spider; import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.SimpleTrigger;
import org.quartz.TriggerBuilder;
import org.quartz.impl.StdSchedulerFactory;
import main.java.sina.bean.info.LoginInfo;
import main.java.sina.httpclient.LoginSina;
import main.java.sina.httpclient.SpiderSina;
import main.java.sina.job.KeywordSearchJob;
import main.java.sina.utils.Constant;
import main.java.sina.utils.HttpHelper;
import main.java.test.SpiderTest; public class Spider { public static void main(String[] args) { Constant.personalHomePage = "****";
LoginInfo.username = "****";
LoginInfo.password = "****";
Constant.enableProxy = false;
Constant.hourbefore = 0; //这个参数用于设置时差
start(); }
public static void start() { final SchedulerFactory factory = new StdSchedulerFactory();
try {
Scheduler scheduler = factory.getScheduler();
JobDetail jobDetail = JobBuilder.newJob(KeywordSearchJob.class)
.withIdentity("keywordSearch", "weibo").build();
SimpleTrigger trigger = TriggerBuilder.newTrigger()
.withIdentity("keywordSearch", "weibo")
.withSchedule(SimpleScheduleBuilder.repeatHourlyForever())
.build();
scheduler.scheduleJob(jobDetail, trigger);
scheduler.start();
} catch (SchedulerException e) {
e.printStackTrace();
}
} public static SpiderSina createSpider() {
LoginSina ls = new LoginSina(LoginInfo.username, LoginInfo.password);
ls.dologinSina();
ls.redirect();
SpiderSina spider = new SpiderSina(ls); return spider;
} public static void sendMidsofDays(SpiderSina spider,String keyword, String fromdate,
String todate) { try {
String midsString = "";
for (int i = 1; i <= 50; i++) {
String htmlContent = spider
.search(keyword, i, fromdate, todate);
if (htmlContent.contains("noresult_support")) {
break;
}
System.out.println(i);
Pattern pattern = Pattern.compile("<div mid=\"([0-9]*)\""); String start = "\"pid\":\"pl_weibo_direct\"";
try {
htmlContent = htmlContent.substring(htmlContent
.indexOf(start));
} catch (Exception e) {
htmlContent = htmlContent.substring(1);
}
htmlContent = htmlContent.replace("\\\"", "\"");
htmlContent = htmlContent.replace("\\/", "/");
Matcher matcher = pattern.matcher(htmlContent);
while (matcher.find()) {
System.out.println(matcher.group(1));
midsString += matcher.group(1) + ",";
}
if (i == 37) {
try {
Thread.sleep(1000 * 60 * 30);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
System.out.println(midsString);
HttpHelper.getLiveData(midsString, Constant.CommentUrl);
} catch (IOException e) {
e.printStackTrace();
} }
}
我们在Spider.start()方法中，看到了作业KeywordSearchJob.class,那么我们来看看这个KeywordSearchJob类的实现,如下：
package main.java.sina.job; import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import main.java.sina.httpclient.SpiderSina;
import main.java.sina.spider.Spider;
import main.java.sina.utils.Constant;
import main.java.sina.utils.Utils; public class KeywordSearchJob implements Job { public void execute(JobExecutionContext arg0) throws JobExecutionException { Constant.enableProxy = false; //我的爬虫中没有使用代理,故值设为false.
String keyword = "%25E5%25AE%2581%25E6%25B3%25A2%25E5%25A4%25A7%25E5%25AD%25A6";//被编码后的关键字
String datehour = Utils.getDateOfSpecifiedPreHour(Constant.hourbefore);//这个工具类实现了时差格式的转换
SpiderSina spider = Spider.createSpider();
spider.forwardToWeiboPage();
Spider.sendMidsofDays(spider,keyword,datehour,datehour);
} }
接下来，我们看几个工具类的实现：首先来看下Utils.java这个类,如下：它实现了日期的格式的一些转换
package main.java.sina.utils; import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

public static void writeFileFromStream(String filename,InputStream in){
if(filename==null || filename.trim().length()==0)
return;
File file=new File(filename);

System.out.println("date2 -" +sdFormat.format(calendar.getTime()));
return sdFormat.format(calendar.getTime());
}
}
再来看一下ThreadPool.java这个类,如下：这是一个线程工具类，定义了线程的一些动作
package main.java.sina.utils; import java.util.List;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors; /** * 线程池工具类
*/
public class ThreadPool {
private ExecutorService service;
private List<Thread> threadList; public ThreadPool(int limite, List<Thread> threadList) {
this.service = Executors.newFixedThreadPool(limite);
this.threadList = threadList;
} public void execute() {
if(threadList==null ||threadList.size()==0) return ;
for (int index = 0; index < threadList.size(); index++) {
Thread t=threadList.get(index);
service.execute(t);
}
}
public boolean isTerminated(){
return service.isTerminated();
} public void shutDown() {
service.shutdown();
}
}
然后再看一下Constant.java这个常量类,如下：常量类把系统总用到的一些常量写在这里，以后项目维护需要更改的时候，方便维护更改
package main.java.sina.utils; /**
* @ClassName: Constant
*
*/
public class Constant {
public static boolean enableProxy = false;
public static String liveCommentUrl = "http://localhost:8080/social-hub-connector/loadingLiveData";
public static String CommentUrl = "http://localhost:8080/social-hub-connector/loadingData";
public static String personalHomePage = "******";
public static String weiboUsername = "*********";
public static String weiboPassword = "*********";
public static int hourbefore = 0;
}
再来看一下Base64Encoder.java类，它对一些字段进行了编码的类，如下：
package main.java.sina.utils; /**
* */
public class Base64Encoder {
private static final char last2byte = (char) Integer.parseInt("00000011", 2);
private static final char last4byte = (char) Integer.parseInt("00001111", 2);
private static final char last6byte = (char) Integer.parseInt("00111111", 2);
private static final char lead6byte = (char) Integer.parseInt("11111100", 2);
private static final char lead4byte = (char) Integer.parseInt("11110000", 2);
private static final char lead2byte = (char) Integer.parseInt("11000000", 2);
private static final char[] encodeTable = new char[]{'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '+', '/'}; public Base64Encoder() {
}
public static String encode(byte[] from) {
StringBuffer to = new StringBuffer((int) (from.length * 1.34) + 3);
int num = 0;
char currentByte = 0;
for (int i = 0; i < from.length; i++) {
num = num % 8;
while (num < 8) {
switch (num) {
case 0:
currentByte = (char) (from[i] & lead6byte);
currentByte = (char) (currentByte >>> 2);
break;
case 2:
currentByte = (char) (from[i] & last6byte);
break;
case 4:
currentByte = (char) (from[i] & last4byte);
currentByte = (char) (currentByte << 2);
if ((i + 1) < from.length) {
currentByte |= (from[i + 1] & lead2byte) >>> 6;
}
break;
case 6:
currentByte = (char) (from[i] & last2byte);
currentByte = (char) (currentByte << 4);
if ((i + 1) < from.length) {
currentByte |= (from[i + 1] & lead4byte) >>> 4;
}
break;
}
to.append(encodeTable[currentByte]);
num += 6;
}
}
if (to.length() % 4 != 0) {
for (int i = 4 - to.length() % 4; i > 0; i--) {
to.append("=");
}
}
return to.toString();
}
}
这个类中，针对新浪的一些特殊的加密规则，写的方法，这个在拼接最终的URl的时候回用到,如根据servertime+nonce两个参数来生成一串字符串加密规则：
package main.java.sina.utils;
import java.io.File;
import java.io.FileReader; import javax.script.Invocable;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager; /**
* */
public class EncodeSuAndSp {
static ScriptEngineManager mgr = new ScriptEngineManager();
static ScriptEngine engine = mgr.getEngineByExtension("js");
static Invocable inv = (Invocable) engine; public static String getEncryptedP(String password,String servertime,String nonce){
String value1="";
try {
engine.eval(new FileReader(new File("js/encrypt.js")));
value1 = String.valueOf(inv.invokeFunction("hex_sha1",password));
value1 = String.valueOf(inv.invokeFunction("hex_sha1",value1));
value1 = String.valueOf(inv.invokeFunction("hex_sha1",value1+servertime+nonce));
} catch (Exception e) {
e.printStackTrace();
}
return value1;
} public static String getEncodedUsername(String username){
String value1="";
try {
engine.eval(new FileReader(new File("js/encrypt.js")));
value1 = String.valueOf(inv.invokeFunction("encode",username));
System.out.println(value1);
} catch (Exception e) {
e.printStackTrace();
}
return value1;
}
}
package main.java.sina.utils;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;
import java.net.URLEncoder;
public class EncodeUtils { public static final String encodeURL(String str,String enc) {
try {
return URLEncoder.encode(str, enc);
} catch (UnsupportedEncodingException e) {
throw new RuntimeException(e);
}
}
public static final String decodeURL(String str,String enc) {
try {
return URLDecoder.decode(str, enc);
} catch (UnsupportedEncodingException e) {
throw new RuntimeException(e);
}
} public static String unicdoeToGB2312(String str) {
String res = null;
if(str==null ){
return "";
}
StringBuffer sb = new StringBuffer();
try {
while (str.length() > 0) {
if (str.startsWith("\\u")) {
int x = 0;
try{
x = Integer.parseInt(str.substring(2, 6), 16);
}catch(Exception ex){
x= 0;
}
sb.append((char) x);

} else {

}

} }
ReadIni.java类，在读文本文件中使用，如下：
