Okhttp cookie获取、持久化存储、设置到webview（腾讯tbs浏览器）
1、Okhttp获取cookie
其实okhttp提供了cookie管理的接口CookieJar，我们只需要继承CookieJar即可
每次okhttp发起请求都会调用：加载saveFromResponse方法，将cookie放、返回给我们；每次请求返回是都会调用loadForRequest方法，我们将自己保存的cookie带入即可；
//保存cookie
@Override
public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
if (cookies != null && cookies.size() > 0) {
//保存cookie操作
}
}
//加载cookie
@Override
public List<Cookie> loadForRequest(HttpUrl url) {
List<Cookie> cookies = cookieStore.get(url);
return cookies;
}
2、okhttp cookie存储持久化
因为okhttp只提供cookie处理方法，不提供保存方法，所以需要自己保存
此处我们保存至手机本地内存中
此处直接贴出保存的的PersistentCookieStore类
public class PersistentCookieStore {
private static final String LOG_TAG = "PersistentCookieStore";
private static final String COOKIE_PREFS = "Cookies_Prefs";
private final Map<String, ConcurrentMap<String, Cookie>> cookies;
private final SharedPreferences cookiePrefs;
public PersistentCookieStore(Context context) {
cookiePrefs = context.getSharedPreferences(COOKIE_PREFS, 0);
ConcurrentMap<String, Cookie> cmp=new ConcurrentHashMap<String, Cookie>();
cookies = new HashMap<String, ConcurrentMap<String, Cookie>>();
//将持久化的cookies缓存到内存中 即map cookies
Map<String, ?> prefsMap = cookiePrefs.getAll();
for (Map.Entry<String, ?> entry : prefsMap.entrySet()) {
String[] cookieNames = TextUtils.split((String) entry.getValue(), ",");
for (String name : cookieNames) {
String encodedCookie = cookiePrefs.getString(name, null);
if (encodedCookie != null) {
Cookie decodedCookie = decodeCookie(encodedCookie);
if (decodedCookie != null) {
if (!cookies.containsKey(entry.getKey())) {
cookies.put(entry.getKey(),
new ConcurrentHashMap<String, Cookie>());
}
cookies.get(entry.getKey()).put(name, decodedCookie);
}
}
}
}
}
protected String getCookieToken(Cookie cookie) {
return cookie.name() + "@" + cookie.domain();
}
public void add(HttpUrl url, Cookie cookie) {
String name = getCookieToken(cookie);
//将cookies缓存到内存中 如果缓存过期 就重置此cookie
//本来判断是否过期是用cookie.persistent()的，但是我怎么试都是过期的
//不知道是我的原因还是哪里不对，所以自己写了判断
if (!isCookieExpired(cookie)) {
if (!cookies.containsKey(url.host())) {
cookies.put(url.host(), new ConcurrentHashMap<String, Cookie>());
}
cookies.get(url.host()).put(name, cookie);
} else {
if (cookies.containsKey(url.host())) {
cookies.get(url.host()).remove(name);
}
}
if(cookies.get(url.host()).keySet()!=null)
{
//讲cookies持久化到本地
SharedPreferences.Editor prefsWriter = cookiePrefs.edit();
prefsWriter.putString(url.host(), TextUtils.join(",", cookies.get(url.host()).keySet()));
prefsWriter.putString(name, encodeCookie(new SerializableOkHttpCookies(cookie)));
prefsWriter.apply();
}
}
/** 当前cookie是否过期 */
private static boolean isCookieExpired(Cookie cookie) {
return cookie.expiresAt() < System.currentTimeMillis();
}
//获取cookie
public List<Cookie> get(HttpUrl url) {
ArrayList<Cookie> ret = new ArrayList<Cookie>();
if (cookies.containsKey(url.host()))
ret.addAll(cookies.get(url.host()).values());
return ret;
}
//移除全部
public boolean removeAll() {
SharedPreferences.Editor prefsWriter = cookiePrefs.edit();
prefsWriter.clear();
prefsWriter.apply();
cookies.clear();
return true;
}
//移除指定cookie
public boolean remove(HttpUrl url, Cookie cookie) {
String name = getCookieToken(cookie);
if (cookies.containsKey(url.host()) && cookies.get(url.host()).containsKey(name)) {
cookies.get(url.host()).remove(name);
SharedPreferences.Editor prefsWriter = cookiePrefs.edit();
if (cookiePrefs.contains(name)) {
prefsWriter.remove(name);
}
prefsWriter.putString(url.host(), TextUtils.join(",", cookies.
get(url.host()).keySet()));
prefsWriter.apply();
return true;
} else {
return false;
}
}
//获取全部
public List<Cookie> getCookies() {
ArrayList<Cookie> ret = new ArrayList<Cookie>();
for (String key : cookies.keySet())
ret.addAll(cookies.get(key).values());
return ret;
}
