如何在Android和/或Java中使用HttpClientpipe理Cookie？
我试图login到一个网站，并维护该会话/ cookie，以便服务器将识别我的login，但我正在努力找出一种方法，从响应中提取cookie并设置为维护我的login请求。 我想知道是否应该采取头“Set-Cookie”或使用CookieStore。 任何帮助是极大的赞赏。 这里是我的代码，有我认为getHeader / getCookie方法会去的注释。
public class Http { DefaultHttpClient client = new DefaultHttpClient(); HttpGet request; HttpEntity entity; HttpResponse response; HttpPost post; CookieStore cookieStore = new BasicCookieStore(); HttpContext localContext = new BasicHttpContext(); public static void setContext() { localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); } public static void getPage(String url) throws Exception { request = new HttpGet(url); response = client.execute(request, localContext); PARSER.preParse(url, response); } public static HttpResponse postPage(List<NameValuePair> params, String host, String action) throws Exception { post = new HttpPost(host + action); post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); response = client.execute(post, localContext); entity = response.getEntity(); if(entity != null) { entity.consumeContent(); } return response; } public void destoyHttp() { client.getConnectionManager().shutdown(); } } 为了让别人更好地理解我的困惑，我添加了一些代码，我知道是否能够工作并维护一个会话，但是当我试图将代码移到我的实际应用程序中时，这个代码就被打破了。
public class HttpClientTest extends Activity{ DefaultHttpClient client = new DefaultHttpClient(); HttpGet request; HttpEntity entity; List<Cookie> cookies; HttpResponse response; HttpPost post; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { getRequest(); } catch (Exception e) { Log.d("My Activity", "Failed"); e.printStackTrace(); } } public void getRequest() throws Exception { final String TAG = "MyActivity"; request = new HttpGet("http://gc.gamestotal.com/i.cfm?p=login&se=4"); response = client.execute(request); String action = "i.cfm?&1028&p=login&se=4"; String yourServer = "http://gc.gamestotal.com/"; post = new HttpPost(yourServer + action); List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("nic", "myusername")); params.add(new BasicNameValuePair("password", "mypassword")); params.add(new BasicNameValuePair("server", "4")); post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8)); response = client.execute(post); entity = response.getEntity(); if(entity != null){ entity.consumeContent(); } request = new HttpGet("http://gc.gamestotal.com/i.cfm?f=com_empire&cm=3"); response = client.execute(request); if(entity != null) { entity.consumeContent(); } } }
我知道一个事实，它可以工作，你可以看到在这个代码中我使用了ContentContent（），但是把它添加到最上面的代码看起来没有什么区别，所以我把它排除了。 有任何想法吗？
编辑：我仍然无法让代码工作保持会议进行。 我从我当前的代码，以及正在工作的第二个代码的cookie张贴Cookie。 也许有人会注意到一个问题，我当然不会。

你需要使用HttpContext。 将Cookie存储设置为上下文，并在执行方法中使用HttpGet / HttpPost传递上下文。 希望这应该有所帮助。
看例子：完整的代码可以在这里find
// Create a local instance of cookie store CookieStore cookieStore = new BasicCookieStore(); // Create local HTTP context HttpContext localContext = new BasicHttpContext(); // Bind custom cookie store to the local context localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); HttpGet httpget = new HttpGet("http://www.google.com/"); System.out.println("executing request " + httpget.getURI()); // Pass local context as a parameter HttpResponse response = httpclient.execute(httpget, localContext);
我无法得到我自己的代码工作（我可能会在以后再工作），但我发现有用的代码在这里Android项目使用httpclient – > http.client（apache），post / get方法和我正在使用的类由Charlie Collins编写，与ZXing Android示例中的Http代码类似。 我最终可能会转向ZXing代码。
对我来说，它没有工作，直到我使HttpContext和CookieStore静态，留下所有请求。
