java applets(未签名)可以创建/读取cookie吗？

Question

我想知道是否可以从未签名的applet向客户端写cookie.

Answer 1

是的,他们可以,你可以使用JSObject.小编在这里,您需要将jre/lib目录中的plugin.jar添加到您的路径中以便进行编译.

读:

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.
