Android HttpClient和Cookies
我在Android中的HttpClient遇到问题：通过使用以下代码，我想使用通过Web视图登录之前已设置的cookie。因此，登录数据应该存在并且确实存在，我对此进行了测试。但是，当我在httppost或httpget中使用cookie时，它不使用登录数据。但是这些cookie实际上应该足以接收需要登录的页面，不是吗？我不确定我是否需要以特殊方式将cookie发送到服务器，或者是否足以将cookie加载到httpcontext中。这是代码：
DefaultHttpClient httpclient = new DefaultHttpClient();CookieStore lCS = new BasicCookieStore();if (CookieManager.getInstance().getCookie(pUrl) != null) { String cookieString = CookieManager.getInstance().getCookie(pUrl); String[] urlCookieArray = cookieString.split(";"); for (int i = 0; i < urlCookieArray.length; i++) { System.out.println(urlCookieArray[i]); String[] singleCookie = urlCookieArray[i].split("="); Cookie urlCookie = new BasicClientCookie(singleCookie[0], singleCookie[1]); lCS.addCookie(urlCookie); }}HttpContext localContext = new BasicHttpContext();httpclient.setCookieStore(lCS);localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);HttpPost httppost = new HttpPost(pUrl); // get the url connection try { StringBuilder sb = new StringBuilder(); HttpResponse response = httpclient.execute(httppost, localContext); InputStream is = response.getEntity().getContent(); InputStreamReader isr = new InputStreamReader(is);而且，如果我运行代码，我只会收到该站点的登录页面，因此它不接受Cookie。

答案1
小编典典我遇到了同样的问题，并且使用了与问题类似的方法，但是没有运气。对我来说起作用的是为每个复制的cookie添加域。（BasicClientCookie
cookie.setDomain（String））
我的效用函数：
public static BasicCookieStore getCookieStore(String cookies, String domain) { String[] cookieValues = cookies.split(";"); BasicCookieStore cs = new BasicCookieStore(); BasicClientCookie cookie; for (int i = 0; i < cookieValues.length; i++) { String[] split = cookieValues[i].split("="); if (split.length == 2) cookie = new BasicClientCookie(split[0], split[1]); else cookie = new BasicClientCookie(split[0], null); cookie.setDomain(domain); cs.addCookie(cookie); } return cs;} String cookies = CookieManager.getInstance().getCookie(url); BasicCookieStore lCS = getCookieStore(cookies, MyApp.sDomain); HttpContext localContext = new BasicHttpContext(); DefaultHttpClient httpclient = new DefaultHttpClient(); httpclient.setCookieStore(lCS); localContext.setAttribute(ClientContext.COOKIE_STORE, lCS); ...

android httpClient (https/http) 的优化构建方式二
由于时间原因，这里只构建所有请求 https 都能通过的请求 client
首先定义（重写）信任管理器
public class SSLTrustManager implements javax.net.ssl.TrustManager,
javax.net.ssl.X509TrustManager ,HostnameVerifier{
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public boolean isServerTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public boolean isClientTrusted(
java.security.cert.X509Certificate[] certs) {
return true;
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType)
throws java.security.cert.CertificateException {
return;
}
@Override
public boolean verify(String urlHostName, SSLSession session) { //允许所有主机
return true;
}
}然后封装
public static HttpURLConnection connect(String strUrl) throws Exception {
javax.net.ssl.TrustManager[] trustAllCerts = new javax.net.ssl.TrustManager[1];
javax.net.ssl.TrustManager tm = new SSLTrustManager();
trustAllCerts[0] = tm;
javax.net.ssl.SSLContext sc = javax.net.ssl.SSLContext
.getInstance("SSL");
sc.init(null, trustAllCerts, null);
javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(sc
.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier((HostnameVerifier) tm);
URL url = new URL(strUrl);
HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
return urlConn;
}测试一下
public void unitest()
{
HttpURLConnection urlConn = connect(''https://github.com/'');
urlConn.setDoInput(true);
urlConn.setRequestMethod("GET");
urlConn.connect();
InputStream is = urlConn.getInputStream();
StringBuffer sb = new StringBuffer();
if(is!=null)
{
BufferedReader br = new BufferedReader(new InputStreamReader(is));
String s = null;
while ((s=br.readLine())!=null)
{
sb.append(s).append("\n");
}
}
System.out.println("Content:\n"+sb.toString());
}try do it!
Android HttpClient Cookie
Android HttpClient是否具有Cookie的自动管理功能？
解决方法
它支持它.
阅读下面的帖子似乎是在调用执行时必须传递相同的HttpContext.
response = httpClient.execute(httpPost,localContext);
究竟该怎么办就是在这篇文章：Android project using httpclient –> http.client (apache),post/get method
How do I manage cookies with HttpClient in Android and/or Java?
Android HttpClient Cookie 保持登录
保存cookie
List<Cookie> cookies = httpClient.getCookieStore().getCookies();
if (cookies != null) {
for (Cookie cookie : cookies) {
String cookieString = cookie.getName() + "=" + cookie.getValue() + "; domain=" + cookie.getDomain();
CookieManager.getInstance().setCookie(cookie.getDomain(), cookieString);
}
}
CookieSyncManager.getInstance().sync();
使用cookie
String[] keyValueSets = CookieManager.getInstance().getCookie(domain).split(";");
for(String cookie : keyValueSets) {
String[] keyValue = cookie.split("=");
String key = keyValue[0];
String value = "";
if(keyValue.length>1) value = keyValue[1];
BasicClientCookie baseCookie = new BasicClientCookie(key, value);
baseCookie.setDomain(domain);
httpClient.getCookieStore().addCookie(baseCookie);
}
