可以java applets（未签名）创建/读取cookie？ [英] can java applets (not signed) create / read cookies?

问题描述

解决方案

是的，你可以使用JSObject为此。
这里的小注释，你需要添加plugin.jar从jre / lib目录到你的路径，以获得这个编译。

  import netscape.javascript.JSObject; 
 
 String data =; 
 String cookiename =fooCookie; 
 JSObject myBrowser = JSObject.getWindow（this）; 
 JSObject myDocument =（JSObject）myBrowser.getMember（document）; 
 
 String myCookie =（String）myDocument.getMember（cookie）; 
 if（myCookie.length（）> 0）{
 String [] cookies = myCookie.split（;）; 
 for（String cookie：cookies）{
 int pos = cookie.indexOf（=）; 
 if（cookie.substring（0，pos）.trim（）。equals（cookiename））{
 data = cookie.substring（pos + 1）; 
 break; 
} 
} 
} 
  

写作：

  String data =test; 
 String cookiename =fooCookie; 
 JSObject win = JSObject.getWindow（this）; 
 JSObject doc =（JSObject）win.getMember（document）; 
 String data = cookiename +=+ data +; path = /; expires = Thu，31-Dec-2019 12:00:00 GMT; 
 doc.setMember（cookie，data）; 
  

不要忘记在Base64中对数据进行编码。

I was wondering if it's possible to write cookies to clients from unsigned applets.

解决方案

Yes they can, you can use JSObject for this. Small note here, you need to add the plugin.jar from the jre/lib directory to your path in order to get this compiled.

Reading:

import netscape.javascript.JSObject;

String data = "";
String cookiename = "fooCookie";
JSObject myBrowser = JSObject.getWindow(this);
JSObject myDocument = (JSObject) myBrowser.getMember("document");

String myCookie = (String) myDocument.getMember("cookie");
if (myCookie.length() > 0) {
    String[] cookies = myCookie.split(";");
    for (String cookie : cookies) {
        int pos = cookie.indexOf("=");
        if (cookie.substring(0, pos).trim().equals(cookiename)) {
            data = cookie.substring(pos + 1);
            break;
        }
    }
}

Writing:

String data = "test";
String cookiename = "fooCookie";
JSObject win = JSObject.getWindow(this);
JSObject doc = (JSObject) win.getMember("document");
String data = cookiename + "=" + data + "; path=/; expires=Thu, 31-Dec-2019 12:00:00 GMT";
doc.setMember("cookie", data);

Don't forget to encode your data in Base64.
