How do I manage cookies with HttpClient in Android and/or Java?
提问by Alejandro Huerta
I am trying to login to a site and maintain that session/cookie so that the server will recognize my login, but I am struggling to figure out a way of extracting the cookie from the response and setting into a request to maintain my login. I'm wondering if I should go about taking the header "Set-Cookie" or using a CookieStore. Any help is greatly appreciated. Here is my code that I have, with comments where I think the getHeader/getCookie methods would go.
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名，但我正在努力找出一种从响应中提取 cookie 并将其设置为请求以维护我的登录名的方法。我想知道是否应该使用标题“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 方法将使用的注释。
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();
}
}
In hopes of others better understanding my confusion am adding code that I know DOES work and maintains a session but when I tried to move the code into my actual application it broke somewhere down the line.
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动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();
}
}
}
I know for a fact it works, and you can see that in this code I consumeContent() but adding that to the top code didn't seem to make a difference so I left it out. Any Ideas?
我知道它确实有效，你可以看到在这段代码中我消耗了内容（），但是将它添加到顶部代码似乎没有什么不同，所以我把它省略了。有任何想法吗？
Edit: I am still unable to get the code working in keeping a session going. I am posting the cookies from my current code, along with the cookies of the second code that is working. Perhaps someone will notice an issue, I certainly do not.
编辑：我仍然无法使代码工作以保持会话继续进行。我正在发布当前代码中的 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，我当然不会。

I was unable to get my own code working (I might work on it again later), but I found useful code here Android project using httpclient --> http.client (apache), post/get methodand I am using the class built by Charlie Collins, which is similar to the Http Code in the ZXing Android example. I may eventually move to the ZXing code.
我无法让我自己的代码工作（我以后可能会再次使用它），但我在Android 项目中找到了有用的代码，使用 httpclient --> http.client (apache), post/get 方法，我正在使用构建的类由 Charlie Collins 编写，类似于 ZXing Android 示例中的 Http 代码。我可能最终会转向 ZXing 代码。

You need to use HttpContext. Set cookie store to context and pass context long with HttpGet/HttpPost in execute method. Hope this should help.
您需要使用 HttpContext。将 cookie 存储设置为上下文并在 execute 方法中使用 HttpGet/HttpPost 传递上下文。希望这应该会有所帮助。
See example: Complete code can be found here
请参阅示例：可以在此处找到完整的代码
// 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);

for me it didn't work, until i made both HttpContext and CookieStore static, to stay for all requests.
对我来说，它不起作用，直到我将 HttpContext 和 CookieStore 设为静态，以保留所有请求。
