仿12306查询火车票功能详解编程语言

首先感谢http://www.zuidaima.com/share/1861712958622720.html对我的帮助，我在此基础上修改了页面的显示，

先上效果吧

public class SearchTrainController implements X509TrustManager 
{ 
 
	private static String QUERY_RUL = "https://kyfw.12306.cn/otn/lcxxcx/query"; 
 
	@RequestMapping(value = "searchTrain", method = RequestMethod.POST) 
	public  
	@ResponseBody String  searchTrain(HttpServletRequest request/**, HttpServletResponse response, PrintWriter pw*/) 
	{ 
		StringBuffer sb = new StringBuffer(); 
		String from_Station = request.getParameter("fromStationText");  
		String to_station = request.getParameter("toStationText");  
		String queryDate = request.getParameter("train_start_date");  
		String purpose_codes = request.getParameter("purpose_codes");   
		try 
		{ 
			TrustManager[] tm = { new MyX509TrustManager() }; 
			SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE"); 
			sslContext.init(null, tm, new java.security.SecureRandom()); 
			SSLSocketFactory ssf = sslContext.getSocketFactory(); 
			String param = "?purpose_codes=" + purpose_codes + "&queryDate=" + queryDate + "&from_station=" + from_Station + "&to_station=" + to_station; 
			System.out.println("URL:"+QUERY_RUL + param); 
			URL url = new URL(QUERY_RUL + param); 
			HttpsURLConnection con = (HttpsURLConnection) url.openConnection(); 
			con.setSSLSocketFactory(ssf); 
			InputStreamReader in = new InputStreamReader(con.getInputStream(), "utf-8"); 
			BufferedReader bfreader = new BufferedReader(in); 
			String line = ""; 
			while ((line = bfreader.readLine()) != null) 
			{ 
				sb.append(line); 
			} 
			//System.out.println(sb.toString()); 
		} 
		catch (Exception e) 
		{ 
			// TODO Auto-generated catch block 
			e.printStackTrace(); 
		} 
 
		return sb.toString(); 
	} 
 
	@Override 
	public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException 
	{ 
		// TODO Auto-generated method stub 
	} 
 
	@Override 
	public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException 
	{ 
		// TODO Auto-generated method stub 
	} 
 
	@Override 
	public X509Certificate[] getAcceptedIssuers() 
	{ 
		// TODO Auto-generated method stub 
		return null; 
	} 
}

接下来是我本地写的一个测试类

public class JunitTest { 
	public static void main(String[] args) throws Exception { 
		TrustManager[] tm = { new MyX509TrustManager() }; 
		SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE"); 
		sslContext.init(null, tm, new java.security.SecureRandom()); 
		SSLSocketFactory ssf = sslContext.getSocketFactory(); 
		String urlStr = "https://kyfw.12306.cn/otn/lcxxcx/query?purpose_codes=ADULT&queryDate=2016-06-06&from_station=BXP&to_station=WHN"; 
		URL url = new URL(urlStr); 
		HttpsURLConnection con = (HttpsURLConnection) url.openConnection(); 
		con.setSSLSocketFactory(ssf); 
		InputStreamReader in = new InputStreamReader(con.getInputStream(), 
				"utf-8"); 
		BufferedReader bfreader = new BufferedReader(in); 
		StringBuffer sb = new StringBuffer(); 
		String line = ""; 
		while ((line = bfreader.readLine()) != null) { 
			sb.append(line); 
		} 
		System.out.println(sb.toString()); 
	} 
}
