如何在Android和/或Java中使用HttpClient管理cookie？

我正试图登录到一个站点并维护该会话/cookie，以便服务器能够识别我的登录，但我正在努力找到一种方法，从响应中提取cookie并将其设置为请求以维护我的登录。我想知道我是应该开始使用标题“Set Cookie”还是使用CookieStore。非常感谢您的帮助。这是我的代码，我认为getHeader/getCookie方法会用到注释

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();
}
}

您需要使用HttpContext。将cookie存储设置为context，并在execute方法中使用HttpGet/HttpPost传递context long。希望这会有所帮助

参见示例：可以找到完整的代码

我无法让我自己的代码正常工作（我可能稍后再处理），但我在这里找到了有用的代码，我使用的是Charlie Collins构建的类，它类似于ZXing Android示例中的Http代码。我可能最终会转到ZXing代码。

对我来说，它不起作用，直到我将HttpContext和CookieStore都设置为静态，以保留所有请求。

好的，我该如何获取标题？我是否从响应中获取它，例如response.getHeader（“Set Cookie”）？因为我尝试过做类似的事情，但是只有一个getHeaders（）；我猜返回数组的方法？我必须再次查找它。好的，我设法使用了Header[]对象，并成功地设置了包含Cookie头的头，但这似乎并没有解决我的问题。我用我自己编写的代码编辑了我的问题，但由于某种原因，当我把它移到我的实际应用程序时，它坏了。仅供参考，工作代码对标题没有任何作用，它只是工作？洛洛克；）我设法从您的代码中找到了一些我认为缺少的东西，并更新了（而不是更改了）我的答案。我感谢您的快速回复。我添加了丢失的代码，但仍然没有运气。将GET和POST部分拆分为两个不同的方法是否会导致客户端无法保留会话？您是否尝试将cookiestore设置为HttpContext，并在httpclient的执行过程中将HttpContext与方法一起传递？

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();
    }    

}

}
