仿12306查询火车票功能

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());
	}
}

这里请求的是12306官网的，这里的请求可能会有token会话，有其他问题的，欢迎留言，主要是练习下。
