Webkit--Cookies分析篇
最近对android的webkit的cookies进行学习，下面是我的简单总结：
1，CookiesManager.java-->CookiesSyncManager.java-->WebviewDatabases.java
CookiesManager.java是对cookies的总体管理，它会调用CookiesSyncManager将Ram里面的Cookies存入到databases.所以CookiesSyncManager是对将cookies同步到database的管理，而WebviewDatabases里面的Webview.db的cookies表是对cookies的存储。
2，CookiesSyncManager.java-->WebSyncManager.java
CookiesSyncManager里面正在维护cookies从ram到databases的是WebSyncManager来做的，这里面是开一个thread来维护。
3，JWebCoreJavaBridge.java-->CookiesSyncManager.java
CookiesManager是对cookies的总体管理，那ram的cookies首先是这里传递给CookiesSyncManager的。那个CookiesManager的ram cookies又是从何处得来的呢？那就是从JWebCoreJavaBridge得到的。
private void setCookies(String url, String docUrl, String value) { if (value.contains("\r") || value.contains("\n")) { // for security reason, filter out '\r' and '\n' from the cookie int size = value.length(); StringBuilder buffer = new StringBuilder(size); int i = 0; while (i != -1 && i < size) { int ir = value.indexOf('\r', i); int in = value.indexOf('\n', i); int newi = (ir == -1) ? in : (in == -1 ? ir : (ir < in ? ir : in)); if (newi > i) { buffer.append(value.subSequence(i, newi)); } else if (newi == -1) { buffer.append(value.subSequence(i, size)); break; } i = newi + 1; } value = buffer.toString(); } CookieManager.getInstance().setCookie(url, value); }voidJavaBridge::setCookies(WebCore::KURL const& url, WebCore::KURL const& docUrl, WebCore::String const& value){ JNIEnv* env = JSC::Bindings::getJNIEnv(); const WebCore::String& urlStr = url.string(); jstring jUrlStr = env->NewString(urlStr.characters(), urlStr.length()); const WebCore::String& docUrlStr = docUrl.string(); jstring jDocUrlStr = env->NewString(docUrlStr.characters(), docUrlStr.length()); jstring jValueStr = env->NewString(value.characters(), value.length()); AutoJObject obj = getRealObject(env, mJavaObject); env->CallVoidMethod(obj.get(), mSetCookies, jUrlStr, jDocUrlStr, jValueStr); env->DeleteLocalRef(jUrlStr); env->DeleteLocalRef(jDocUrlStr); env->DeleteLocalRef(jValueStr);}
