Webkit-Cookies分析篇

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);
    }

CookieManager.getInstance().setCookie(url, value);

4，JavaBridge.cpp-->JWebCoreJavaBridge.java
JWebCoreJavaBridge的cookies是从JavaBridge.cpp得来的

void
JavaBridge::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);
}

mSetCookies = env->GetMethodID(clazz, "setCookies", "(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V");
env->CallVoidMethod(obj.get(), mSetCookies, jUrlStr, jDocUrlStr, jValueStr);

5，CookieClient.h-->JavaBridge.cpp
JavaBridger.cpp是继承CookiesClient
6，Cookies.cpp-->CookiesClien.h

就分析到这里，就没往下追了，有空我继续分析。
