有没有办法从Java小程序读取浏览器的Cookie？

Question

I have a java applet that needs to do http requests to the server. A quick experiment showed that the session id cookies from the browser is not sent along, so i'll have to set it manually. Currently, I see 2 possible solutions:

• somehow get hold of the cookie data from within the applet
• pass the cookie information into the applet's contructor via javascript

I'd prefer the first solution, but i wasn't able to find a working solution for that. all information i found (mostly netscape.javascript.JSObject) were outdated (my 1.5 VM does not have this class)

Any great ideas or resources i have not yet found?

Answer 1

Are you sure your JVM doesn't contain this class? You should look in $JAVA_HOME/lib/plugin.jar . I found it in my 1.5.0_14 installation.

If you are generating the page dynamically, you don't necessarily need to use JavaScript to communicate the session ID. As long as you know it server-side, you can place it into an applet parameter tag in the generated HTML which contains the <applet> tag.

Answer 2

如今，所有浏览器都支持httponly cookie。如果在相应的响应标头中有意识地在服务器中将cookie设置为“ httponly”，则小应用程序可能无法访问它。
