发送cookies作为http get的一部分遇到麻烦.首先我去一个webview中的一个登录页面给我一个cookie.我已经检查并将cookie存储在CookieManager中.然后我使用BasicHttpRequest从同一个域获取一个特定的URL.我希望我从登录中获得的cookie被附加到我的头文件中,但是在Wireshark中看到它不在那里.我已经搜索并阅读了很多类似的问题,并确定:
>我正在使用CookieSyncManager,所以我希望我的cookies从会话将持续.我不认为CookieSyncManager是异步的,因为我每隔5秒不间断地访问该URL,并且不会添加cookie.
>我怀疑我需要告诉我关于我的Cookie商店的http请求,但是我已经google的解决方案不会为我编译.看起来我想做一些看起来像context.setAttribute(ClientContext.COOKIE_STORE,this.cookieStore)的东西,但是我不知道如何从CookieManager获取默认的CookieStore.一些代码似乎称为cookieManager.getCookieStore(),但是在Android上并不为我编译.看看文档,我看不到一种方式来获得这个似乎很疯狂的CookieStore – 我缺少一些明显的东西?
我的代码启动我的Webview中的登录页面看起来像:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// use cookies to remember a logged in status
CookieSyncManager.createInstance(this);
CookieSyncManager.getInstance().startSync();
//not sure if I need to do this
CookieManager cookie_manager = CookieManager.getInstance();
cookie_manager.setAcceptCookie(true);
webview = new WebView(this);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new HelloWebViewClient()); // if user clicks on a url we need to steal that click,also steal the back button
webview.loadUrl("http://"+my_server+"/api/v1/login");
setContentView(webview);
然后我的代码检查cookie是有看起来像:
public static boolean CheckAuthorised() {
CookieSyncManager.getInstance().sync();
CookieManager cookie_manager = CookieManager.getInstance();
String cookie_string = cookie_manager.getCookie("http://"+my_server+"/api/v1/login");
System.out.println("lbp.me cookie_string: " + cookie_string);
if(cookie_string != null)
{
String[] cookies = cookie_string.split(";");
for (String cookie : cookies)
{
if(cookie.matches("API_AUTH=.*"))
{
// maybe we need to store the cookie for the root of the domain?
cookie_manager.setCookie("http://"+my_server,cookie_string);
// maybe we need to store the cookie for the url we're actually going to access?
cookie_manager.setCookie("http://"+my_server+"/api/v1/activity",cookie_string);
CookieSyncManager.getInstance().sync();
return true;
}
}
}
return false;
}
并且实际上使我做的http请求
public static HttpResponse getMeAWebpage(String host_string,int port,String url)
throws Exception {
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params,HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params,"UTF-8");
HttpProtocolParams.setUserAgent(params,"HttpComponents/1.1");
HttpProtocolParams.setUseExpectContinue(params,true);
BasicHttpProcessor httpproc = new BasicHttpProcessor();
// required protocol interceptors
httpproc.addInterceptor(new RequestContent());
httpproc.addInterceptor(new RequestTargetHost());
// Recommended protocol interceptors
httpproc.addInterceptor(new RequestConnControl());
httpproc.addInterceptor(new RequestUserAgent());
httpproc.addInterceptor(new RequestExpectContinue());
HttpRequestExecutor httpexecutor = new HttpRequestExecutor();
HttpContext context = new BasicHttpContext(null);
// HttpHost host = new HttpHost("www.svd.se",80);
HttpHost host = new HttpHost(host_string,port);
DefaultHttpClientConnection conn = new DefaultHttpClientConnection();
ConnectionReuseStrategy connStrategy = new DefaultConnectionReuseStrategy();
context.setAttribute(ExecutionContext.HTTP_CONNECTION,conn);
context.setAttribute(ExecutionContext.HTTP_TARGET_HOST,host);
//CookieManager cookie_manager = CookieManager.getInstance();
//CookieStore cookie_store = cookie_manager.getCookieStore(); //The method getCookieStore() is undefined for the type CookieManager
//context.setAttribute(ClientContext.COOKIE_STORE,cookie_store);
HttpResponse response = null;
try {
if (!conn.isopen()) {
Socket socket = new Socket(host.getHostName(),host.getPort());
conn.bind(socket,params);
}
BasicHttpRequest request = new BasicHttpRequest("GET",url);
System.out.println(">> Request URI: "
+ request.getRequestLine().getUri());
System.out.println(">> Request: "
+ request.getRequestLine());
request.setParams(params);
httpexecutor.preProcess(request,httpproc,context);
response = httpexecutor.execute(request,conn,context);
response.setParams(params);
httpexecutor.postProcess(response,context);
String ret = EntityUtils.toString(response.getEntity());
System.out.println("<< Response: " + response.getStatusLine());
System.out.println(ret);
System.out.println("==============");
if (!connStrategy.keepAlive(response,context)) {
conn.close();
} else {
System.out.println("Connection kept alive...");
}
} catch(UnkNownHostException e) {
System.out.println("UnkNownHostException");
} catch (HttpException e) {
System.out.println("HttpException");
} finally {
conn.close();
}
return response;
}
谢谢你读这个远!有意见的建议,

解决方法
附加cookies终于为我工作了!我可能没有做到最简单的方法,但至少它是有效的.我的大突破是下载和附加Android源码,以便我可以浏览并看看发生了什么.这里有说明
http://blog.michael-forster.de/2008/12/view-android-source-code-in-eclipse.html – 向下滚动并从Volure读取评论以获得最简单的下载.如果您在Android上开发,我强烈建议您这样做.
现在开始工作的Cookie代码 – 大多数更改是在代码中实际上让我的网页 – 我不得不设置一个COOKIE_STORE和一个COOKIESPEC_REGISTRY.然后我也不得不更改我的连接类型,因为cookie代码将其转换为ManagedClientConnection:
public static HttpResponse getMeAWebpage(String host_string,true);
//params.setParameter("cookie",cookie);
BasicHttpProcessor httpproc = new BasicHttpProcessor();
// required protocol interceptors
httpproc.addInterceptor(new RequestContent());
httpproc.addInterceptor(new RequestTargetHost());
// Recommended protocol interceptors
httpproc.addInterceptor(new RequestConnControl());
httpproc.addInterceptor(new RequestUserAgent());
httpproc.addInterceptor(new RequestExpectContinue());
httpproc.addInterceptor(new RequestAddCookies());
HttpRequestExecutor httpexecutor = new HttpRequestExecutor();
HttpContext context = new BasicHttpContext(null);
// HttpHost host = new HttpHost("www.svd.se",port);
HttpRoute route = new HttpRoute(host,null,false);
// Create and initialize scheme registry
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http",PlainSocketFactory.getSocketFactory(),80));
schemeRegistry.register(new Scheme("https",SSLSocketFactory.getSocketFactory(),443));
SingleClientConnManager conn_mgr = new SingleClientConnManager(params,schemeRegistry);
ManagedClientConnection conn = conn_mgr.getConnection(route,null /*state*/);
ConnectionReuseStrategy connStrategy = new DefaultConnectionReuseStrategy();
context.setAttribute(ExecutionContext.HTTP_CONNECTION,host);
CookieStore cookie_store = new BasicCookieStore();
cookie_store.addCookie(cookie);
context.setAttribute(ClientContext.COOKIE_STORE,cookie_store);
// not sure if I need to add all these specs,but may as well
CookieSpecRegistry cookie_spec_registry = new CookieSpecRegistry();
cookie_spec_registry.register(
CookiePolicy.BEST_MATCH,new BestMatchSpecFactory());
cookie_spec_registry.register(
CookiePolicy.broWSER_COMPATIBILITY,new browserCompatSpecFactory());
cookie_spec_registry.register(
CookiePolicy.netscape,new netscapeDraftSpecFactory());
cookie_spec_registry.register(
CookiePolicy.RFC_2109,new RFC2109SpecFactory());
cookie_spec_registry.register(
CookiePolicy.RFC_2965,new RFC2965SpecFactory());
//cookie_spec_registry.register(
// CookiePolicy.IGnorE_COOKIES,// new IgnoreSpecFactory());
context.setAttribute(ClientContext.COOKIESPEC_REGISTRY,cookie_spec_registry);
HttpResponse response = null;
try {
if (!conn.isopen()) {
conn.open(route,context,params);
}
BasicHttpRequest request = new BasicHttpRequest("GET",context)) {
conn.close();
} else {
System.out.println("Connection kept alive...");
}
} catch(UnkNownHostException e) {
System.out.println("UnkNownHostException");
} catch (HttpException e) {
System.out.println("HttpException");
} finally {
conn.close();
}
return response;
}
我的代码设置我的cookie住在与getMeAWebpage()看起来像一样的类:
public static void SetCookie(String auth_cookie,String domain)
{
String[] cookie_bits = auth_cookie.split("=");
cookie = new BasicclientCookie(cookie_bits[0],cookie_bits[1]);
cookie.setDomain(domain); // domain must not have 'http://' on the front
cookie.setComment("put a comment here if you like describing your cookie");
//cookie.setPath("/blah"); I don't need to set the path - I want the cookie to apply to everything in my domain
//cookie.setVersion(1); I don't set the version so that I get less strict checking for cookie matches and am more likely to actually get the cookie into the header! Might want to play with this when you've got it working...
}
如果你遇到类似的问题,我真的希望这有帮助 – 我觉得我的头撞在墙上了几个星期!现在为了一个当之无愧的庆祝杯茶:o)
