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

标签: java android cookies httpclient

我正在尝试登录网站并维护该会话/ cookie,以便服务器识别我的登录信息,但我正在努力找出一种从响应中提取cookie并设置为维护我的请求的方法登录。我想知道我是否应该采用标题“Set-Cookie”或使用CookieStore。任何帮助是极大的赞赏。这是我的代码,其中包含我认为getHeader / getCookie方法的注释。

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();
}
}

希望其他人能够更好地理解我的困惑,添加我知道的代码可以工作并保持会话但是当我尝试将代码移动到我的实际应用程序时,它就破坏了某个地方。

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,你可以看到在这段代码中我使用了一个内容(),但是将它添加到顶部代码似乎没有什么区别所以我把它留了出来。任何想法?

编辑:我仍然无法让代码工作以保持会话继续进行。我发布了当前代码中的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,我当然不会。

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。

参见示例:可以找到完整代码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);

我无法使自己的代码正常工作(我可能会在以后再次使用它),但我在这里找到了有用的代码Android project using httpclient --> http.client (apache), post/get method并且我使用的是Charlie Collins构建的类,它类似于Http ZXing Android示例中的代码。我最终可能会转向ZXing代码。

对我来说,它不起作用,直到我使HttpContext和CookieStore都是静态的,才能保留所有请求。
