RT。由于在使用CMCC-EDU进行上网时，在网页里登陆极其慢，

所以昨天花半天时间实现了一个CMCC-EDU登陆器。

思路就是，从浏览器先手工登陆抓包，分析整个登陆的过程，然后用程序去模拟。

针对每一个Get 和Post 分析其带的参数，提交到的地址，模拟

程序使用了httpcomponents-client-4.3.jar、和Jsoup-1.7.2.jar第三方类库。



PS：1.试了好多遍打jar文件，但是都运行不了，实在是没耐心了，有哪个网友知道怎么弄麻烦告知下。。。

  2.显示用了多久时间的还没弄好。回头再弄吧。！


上代码


1.界面程序

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JTextField;

import org.apache.http.client.CookieStore;
import org.apache.http.impl.client.BasicCookieStore;


public class MainFrame extends JFrame{

	/**
	 * @param args
	 */
	public static String name="";
	public static String password="";
	private static CookieStore cookieStore=new BasicCookieStore();
	CMCC cmcc;
	JTextField textName,textPassword;
	JButton btStart,btEnd;
	JLabel labelName;
	JLabel labelEmail;
	
	public MainFrame(){
		setSize(220,200);
		setTitle("CMCC-EDU登陆器  by Sumrise");
		setLocationRelativeTo(null);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		textName=new JTextField("账号",10);
		textPassword=new JTextField("密码",10);
		labelName=new JLabel("CMCC登陆器 by Sumrise");
		labelEmail=new JLabel("联系方式：sumrise@vip@qq.com");
		setLayout(new FlowLayout());
		add(textName);
		add(textPassword);
		add(labelName);
		add(labelEmail);
		btStart=new JButton("登陆");
		btEnd=new JButton("下线");
		add(btStart);
		add(btEnd);
		setVisible(true);
		
		btStart.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				if(! textName.getText().trim().equals("账号"))
					name=textName.getText().trim();
				if(! textPassword.getText().trim().equals("密码"))
					password=textPassword.getText().trim();
				
				JOptionPane.showMessageDialog(null, "正在登陆请稍等几秒");
				cmcc=new CMCC(MainFrame.this);
				new Thread(cmcc).start();
			}
		});
		btEnd.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent e) {
				cmcc.unload();
			}
		});
		textName.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				if(textName.getText().trim().equals("账号"))
					textName.setText("");
			}
		});
		textPassword.addMouseListener(new MouseAdapter() {
			@Override
			public void mouseClicked(MouseEvent e) {
				if(textPassword.getText().trim().equals("密码"))
					textPassword.setText("");
			}
		});
		
	}
	public static void main(String[] args) {

	}

}
