android HttpURLConnection ,HttpClient设置Cookie

上一阶段项目设计使用cookie信息实现登录访问功能，在实现过程遇到一些问题，下面整理一下：

首先，client想使用cookie,必须访问一次server从会话中获取cookie信息，然后在设置回去，在android使用HttpURLConnection 直接设置会报异常

查阅文档及StackOver发现android需要使用CookieManager进行处理cookie相关信息，实现如下：

 InputStream input = null;

        OutputStream output = null;

        HttpURLConnection connection = null;

        try {

            java.net.CookieManager manager = new java.net.CookieManager();

            manager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);

            CookieHandler.setDefault(manager);

            URL url = new URL(dnUrl);

            connection = (HttpURLConnection) url.openConnection();

            connection.setRequestMethod("GET");

            connection.connect();

            connection.getHeaderFields();

            CookieStore store = manager.getCookieStore();

            int resultCode=connection.getResponseCode();

            responseUpdateCookieHttpURL(store);

           //  expect HTTP 200 OK, so we don't mistakenly save error report

           //  instead of the file

            if (resultCode != HttpURLConnection.HTTP_OK) {

                return "Server returned HTTP " + connection.getResponseCode()

                        + " " + connection.getResponseMessage();

            }

  /**

     * 更新本地Cookie信息

     */

    @SuppressLint("NewApi")

    @TargetApi(Build.VERSION_CODES.GINGERBREAD)

    public static void responseUpdateCookieHttpURL(CookieStore store) {

        boolean needUpdate = false;

        List<HttpCookie> cookies = store.getCookies();

        HashMap<String, String> cookieMap = null;

        if (cookieMap == null) {

            cookieMap = new HashMap<String, String>();

        }

        for (HttpCookie cookie : cookies) {

            String key = cookie.getName();

            String value = cookie.getValue();

            if (cookieMap.size() == 0 || !value.equals(cookieMap.get(key))) {

                needUpdate = true;

            }

            cookieMap.put(key, value);

    //        BDebug.e(HTTP_COOKIE, cookie.getName() + "---->" + cookie.getDomain() + "------>" + cookie.getPath());

        }

    }

 public static final int GET = 0;

    public static final int POST = 1;

    public static final String HTTP_POST_BODY = "body";

    public static final String HTTP_COOKIE = "Cookie";

    public static final String HTTP_USER_AGENT = "User-Agent";

HttpClient实现更改设置Cookie信息：

void handleCookie(String url){

		try{

			HttpClient client = new DefaultHttpClient();

		    HttpGet httpget = new HttpGet(url);

		    HttpResponse httpResponse = client.execute(httpget);  

		    int responseCode = httpResponse.getStatusLine().getStatusCode();

            HttpBuilder.responseUpdateCookieHttpClient((DefaultHttpClient)client);

            if (responseCode == HttpStatus.SC_OK) {

                /*result = EntityUtils.toString(httpResponse.getEntity());

                HttpEntity entity = response.getEntity();

                InputStream is = entity.getContent();*/

            }

		}catch(Exception e){

			e.printStackTrace();

		}

	}

   /**

     * 获取cookie信息

     *

     * @param cookieMap

     * @return

     */

    public static String getCookieInfo(HashMap<String, String> cookieMap) {

        StringBuilder cookieInfo = new StringBuilder();

        if (cookieMap != null && cookieMap.size() > 0) {

            Iterator<Entry<String, String>> iter = cookieMap.entrySet().iterator();

            Entry<String, String> entry;

            while (iter.hasNext()) {

                String key = "";

                String value = "";

                entry = iter.next();

                key = entry.getKey();

                value = entry.getValue();

                cookieInfo.append(key).append("=").append(value).append(";");

            }

        }

        return cookieInfo.toString();

    }

    /**

     * 更新本地Cookie信息

     *

     * @param defaultHttpClient

     */

    public static void responseUpdateCookieHttpClient(DefaultHttpClient defaultHttpClient) {

        boolean needUpdate = false;

        List<Cookie> cookies = defaultHttpClient.getCookieStore().getCookies();

        HashMap<String, String> cookieMap = null;

        if (cookieMap == null) {

            cookieMap = new HashMap<String, String>();

        }

        for (Cookie cookie : cookies) {

            String key = cookie.getName();

            String value = cookie.getValue();

            if (cookieMap.size() == 0 || !value.equals(cookieMap.get(key))) {

                needUpdate = true;

            }

            cookieMap.put(key, value);

        }

    }

基本就这些，有问题留言。
