基本上我只想从服务器获取cookie。这是一个简单的代码,但我想这并不足以让每个cookie像例如sessionID等。
import java.net.*;
import java.util.*;
public class Cookie {
public static void main(String[] args) {
try {
URL url = new URL("http://www.google.com/");
URLConnection conn = url.openConnection();
System.out.println(con.getHeaderField("Set-Cookie"));
} catch (Exception e) { }
}
}
结果显示我只获得一个cookie:
NID=61=nNSsAl4g7DfxqHE7t__ghfoCc_J-RmY7PaTNoPOd_khLdvvuqI-fnteHgnQXMzmxj_C5HdMozcGfOTt8PvePLKpbDdUlzdVZiRKwNpQIej6_T69jt9C7Oi6E4F-gWPHD; expires=Mon, 14-Jan-2013 17:16:40 GMT; path=/; domain=.google.pl; HttpOnly
Firefox获取NID和PREF,因此无效。
有没有办法获得PREF cookie?
任何人都可以告诉我这是发送POST的正确方法(下面的代码)。
import java.io.*;
import java.net.URL;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import javax.net.ssl.HttpsURLConnection;
public class Cookie_Example {
public static void main(String[] args){
try{
String https_url = "https://ssl.filmweb.pl/j_login";
URL url = new URL(https_url);
String post = "_login_redirect_url=http%253A%252F%252Fwww.filmweb.pl%252F&j_username=test.filmweb%40gmail.com&j_password=test.filmweb&_rememberMe=on&pass=zaloguj";
HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
con.setInstanceFollowRedirects(false);
con.setDoInput(true);
con.setDoOutput(true);
con.setRequestMethod("GET");
con.setRequestProperty("Host", "ssl.filmweb.pl");
con.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0.1");
con.setRequestProperty("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
con.setRequestProperty("Accept-Language","pl,en-us;q=0.7,en;q=0.3");
con.setRequestProperty("Accept-Encoding","gzip, deflate");
con.setRequestProperty("Connection","keep-alive");
con.setRequestProperty("Referer","https://ssl.filmweb.pl/login");
con.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
con.setRequestProperty("Content-Length",post.length()+"");
DataOutput output = new DataOutputStream(new BufferedOutputStream(con.getOutputStream()));
output.write(post.getBytes());
Map<String, List<String>> hf = con.getHeaderFields();
Iterator it = hf.entrySet().iterator();
while (it.hasNext()) {
Map.Entry pairs = (Map.Entry)it.next();
System.out.println(pairs.getKey() + " = " + pairs.getValue());
}
} catch (Exception e) {
}
}
}
结果是空cookie,
Set-Cookie = [_artuser_rememberMe=;Path=/;Domain=filmweb.pl;Expires=Thu, 01-Jan-1970 00:00:00 GMT]

这意味着此代码也不起作用。我怎样才能获得__utma,__ utmz等cookie? 谁能帮我?哪些书有用?
答案 0 :(得分:9)
我认为,使用您的声明con.getHeaderField("Set-Cookie")"
,您只需检索一个标头。但也许服务器会在两个不同的标题中向您发送两个cookie。
我使用另一个语句来检索所有Cookie标头:
List<String> cookies = connection.getHeaderFields().get("Set-Cookie");
要查看发送给服务器的内容以及服务器发送给您的内容,我建议您在程序(或Web导航器)和服务器之间使用代理。也许Charles proxy
可以帮到你。
