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

Question

我正在尝试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，但我正在努力找出一种从响应中提取 cookie 并将其设置到请求中以维护我的登录的方法。我想知道是否应该采用标头“Set-Cookie”或使用 CookieStore。非常感谢任何帮助。这是我的代码，其中包含我认为 getHeader/getCookie 方法应该去的注释。

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();
}
}

为了让其他人更好地理解我的困惑，我添加了我知道可以工作并维护会话的代码，但是当我尝试将代码移到我的实际应用程序中时，它在某处崩溃了。

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();
    }    

}

}

我知道它确实有效，并且您可以看到在这段代码中我使用了 ConsumerContent() 但将其添加到顶部代码似乎没有什么区别，所以我将其保留。有什么想法吗？

编辑：我仍然无法让代码正常工作以保持会话继续进行。我将发布当前代码中的 cookie 以及正在运行的第二个代码的 cookie。也许有人会注意到一个问题，但我当然不会。

Answer 1

您需要使用 HttpContext。将 cookie 存储设置为上下文，并在执行方法中使用 HttpGet/HttpPost 传递上下文长。希望这会有所帮助。

查看示例：完整代码可以找到 此处

   // 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);

Answer 2

我无法让自己的代码正常工作（稍后我可能会再次使用它），但我在这里找到了有用的代码 使用httpclient的Android项目 --> http.client (apache)，post/get方法，我使用的是Charlie Collins构建的类，它类似于ZXing Android示例中的Http代码。我最终可能会转向 ZXing 代码。

Answer 3

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