我已经实现了我自己的想法。它实际上很酷。我创建了自己的实现,java.net.CookieManager
它将所有请求转发到 WebView 的 webkit android.webkit.CookieManager
。这意味着不需要同步,并且 HttpURLConnection 使用与 WebView相同的cookie 存储。
WebkitCookieManagerProxy 类:
import java.io.IOException;
import java.net.CookieManager;
import java.net.CookiePolicy;
import java.net.CookieStore;
import java.net.URI;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
public class WebkitCookieManagerProxy extends CookieManager
{
private android.webkit.CookieManager webkitCookieManager;
public WebkitCookieManagerProxy()
{
this(null, null);
}
public WebkitCookieManagerProxy(CookieStore store, CookiePolicy cookiePolicy)
{
super(null, cookiePolicy);
this.webkitCookieManager = android.webkit.CookieManager.getInstance();
}
@Override
public void put(URI uri, Map<String, List<String>> responseHeaders) throws IOException
{
// make sure our args are valid
if ((uri == null) || (responseHeaders == null)) return;
// save our url once
String url = uri.toString();
// go over the headers
for (String headerKey : responseHeaders.keySet())
{
// ignore headers which aren't cookie related
if ((headerKey == null) || !(headerKey.equalsIgnoreCase("Set-Cookie2") || headerKey.equalsIgnoreCase("Set-Cookie"))) continue;
// process each of the headers
for (String headerValue : responseHeaders.get(headerKey))
{
this.webkitCookieManager.setCookie(url, headerValue);
}
}
}
@Override
public Map<String, List<String>> get(URI uri, Map<String, List<String>> requestHeaders) throws IOException
{
// make sure our args are valid
if ((uri == null) || (requestHeaders == null)) throw new IllegalArgumentException("Argument is null");
// save our url once
String url = uri.toString();
// prepare our response
Map<String, List<String>> res = new java.util.HashMap<String, List<String>>();
// get the cookie
String cookie = this.webkitCookieManager.getCookie(url);
// return it
if (cookie != null) res.put("Cookie", Arrays.asList(cookie));
return res;
}
@Override
public CookieStore getCookieStore()
{
// we don't want anyone to work with this cookie store directly
throw new UnsupportedOperationException();
}
}
并通过在您的应用程序初始化中执行此操作来使用它:
android.webkit.CookieSyncManager.createInstance(appContext);
// unrelated, just make sure cookies are generally allowed
android.webkit.CookieManager.getInstance().setAcceptCookie(true);
// magic starts here
WebkitCookieManagerProxy coreCookieManager = new WebkitCookieManagerProxy(null, java.net.CookiePolicy.ACCEPT_ALL);
java.net.CookieHandler.setDefault(coreCookieManager);
测试
我最初的测试表明这运行良好。我看到了 WebView 和 HttpURLConnection 之间共享的 cookie。我希望我不会遇到任何问题。如果您尝试此操作并发现任何问题,请发表评论。
