的URLConnection的Cookies？

问题描述

我试图让该支持Cookie一个URLConnection。根据该文件，我可以使用：

I'm trying to make a URLConnection that supports cookies. According to the documentation I can use:

CookieManager cookieManager = new CookieManager();
CookieHandler.setDefault(cookieManager);

我不能让这个code的工作，然后我看到这仅适用于API 9（2.3）。然而，我没有得到使用CookieManager错误在较旧的模拟器，CookieManager存在，但不能被构成。有没有什么办法，使这项工作的早期版本？我想：

I couldn't get this code to work, then I saw this only works for API 9 (2.3). However, I don't get an error using CookieManager in an older emulator, CookieManager exists, but can't be constructed. Is there any way to make this work for earlier versions? I tried:

            cookieManager.setAcceptCookie(true);
            URLConnection con = u.openConnection();

            con.setRequestProperty("Cookie", cookieManager.getInstance().getCookie(url););
            con.setDoOutput(true);
            con.connect();
            String addCookie = con.getHeaderField("Set-Cookie");
            System.out.println(con.getHeaderFields().toString());
            if (addCookie!=null) {
                cookieManager.getInstance().setCookie(url, addCookie);
            }

但这不起作用。

but this doesn't work.

推荐答案

我是能够使使用伊恩·布朗的CookieManager类饼干：http://www.hccp.org/java-net-cookie-how-to.html

I was able to enable cookies using Ian Brown's CookieManager class:http://www.hccp.org/java-net-cookie-how-to.html

我改名为IansCookieManager，设置类变量_CM =新IansCookieManager，现在它的简单：

I renamed it to IansCookieManager, set a class variable _CM = new IansCookieManager, now it's simple:

            URLConnection conn = u.openConnection();
            _CM.setCookies(conn);
            conn.connect();
            _CM.storeCookies(conn);
            ...
