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

Question

我试图登录到一个网站，并维持该会话/ cookie，以便服务器将识别我的登录名，但我很努力想出一种方法从响应中提取cookie并设置为维护我的登录请求。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，其中有我认为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(); 
} 
} 

在别人更好地理解我的困惑我加入的代码，我知道不工作，并保持会话，但是当我试图将代码移植到我的实际应用中它的地方下了线突破的希望。

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(); 
    }  

} 

} 

我知道它的工作原理其实你可以看到，在该代码我consumeContent（），但补充说顶端代码似乎并没有发挥作用，所以我离开了出来。有任何想法吗？

编辑：我仍然无法让代码工作保持会话进行。我从我当前的代码发布cookie，以及正在工作的第二个代码的cookie。也许有人会注意到一个问题，我当然不会。

Answer 1

我无法得到我自己的代码工作（我可能会再次后工作），但我在这里找到有用的代码Android project using httpclient --> http.client (apache), post/get method，我使用由Charlie Collins构建的类，类似于ZXing Android示例中的Http代码。我最终可能会转向ZXing代码。

Answer 2

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。希望这应该有所帮助。

见例如：完整代码可以发现here

// 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 3

对我来说，它不工作，直到我使HttpContext和CookieStore静态，以保持所有请求。
