仿12306查询火车票功能

首先感谢http://***/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。
