Java 模拟cookie登陆

最近在做将禅道上的功能接口做到手机端，在做登陆的时候，看了禅道的源码，是由cookie来登陆，所以要做一个模拟cookie登陆的接口，将拿到的cookie放到每次接口请求的头部中去，就可以正常访问了。

import java.io.OutputStreamWriter;
    import java.net.HttpURLConnection;
    import java.net.URL;

    public class ImitateLoginController {
    
        public static void main(String args[]) throws Exception {
            //登陆接口地址
            String loginStr = "http://zenta.51fb.com/index.php?m=user&f=login";
            /**
             * 首先要和URL下的URLConnection对话。 URLConnection可以很容易的从URL得到。比如： // Using
             * java.net.URL and //java.net.URLConnection
             */
            URL url = new URL(loginStr);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoOutput(true);
            OutputStreamWriter out = new OutputStreamWriter(connection
                    .getOutputStream(), "GBK");
            //其中的account和password可以通过控制台去查看，或者看页面html去查看
            out.write("account=you-user-name&password=you-password"); 
    // remember to clean up
            out.flush();
            out.close();
    
    // 取得cookie，使用该cookie放在头部就可以访问其他需要登陆才可以访问的接口了
            String cookieVal = connection.getHeaderField("Set-Cookie");
    
    /*------------------------------------访问其他接口-------------------------------------------------*/
            String otherUrl = "http://zenta.51fb.com/index.php?m=bug&f=browse";
            url = new URL(otherUrl);
            HttpURLConnection otherConnection = (HttpURLConnection) url.openConnection();
            if(cookieVal != null){
                otherConnection.setRequestProperty("Cookie",cookieVal);
            }
            otherConnection.connect();
            InputStream urlStream = otherConnection.getInputStream();
            BufferedReader bufferedReader = new BufferedReader(
                    new InputStreamReader(urlStream));
            String content = null;
            StringBuilder total = new StringBuilder();
            while ((content = bufferedReader.readLine()) != null) {
                total.append(content);
            }
            bufferedReader.close();
            System.out.println(content);
        }
    }
