用java写的一个模拟登录程序,转到userInfo 页面时却得不到用户信息,怀疑是得不到session。
贴上代码,像这样先取得cookie 再发回去的方法好像不可行?
public static void login() throws HttpException, IOException{
URL url = new URL("http://localhost/ONCAPS/login.php");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);//允许连接提交信息
connection.setRequestMethod("POST");//网页提交方式“GET”、“POST”
connection.setRequestProperty("User-Agent", "Mozilla/4.7 en");
StringBuffer sb = new StringBuffer();
sb.append("user_id=test1");
sb.append("password=123456");
OutputStream os = connection.getOutputStream();
os.write(sb.toString().getBytes());
os.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String responseCookie = connection.getHeaderField("Set-Cookie");//取到所用的Cookie
System.out.println("cookie:" + responseCookie);
String line = br.readLine();
while (line != null) {
System.out.println(new String(line.getBytes()));
line = br.readLine();//打出登录的网页
}
//acces
URL url1 = new URL("http://localhost/ONCAPS/userInfo.php");
HttpURLConnection connection1 = (HttpURLConnection) url1.openConnection();
connection1.setRequestProperty("Cookie", responseCookie);//给服务器送登录后的cookie
BufferedReader br1 = new BufferedReader(new InputStreamReader(connection1.getInputStream()));
String line1= br1.readLine();
while (line1 != null) {
System.out.println(new String(line1.getBytes()));
line1 = br1.readLine();
}
}
谢谢各位
