使用 OkHttp 3.0,您可以使用类似于与 HttpURLConnection 共享的方法,通过创建使用 webkit cookie 存储的 WebkitCookieManagerProxy。改编自将 cookie 从 HttpURLConnection (java.net.CookieManager) 传递到 WebView (android.webkit.CookieManager) https://stackoverflow.com/questions/12731211/pass-cookies-from-httpurlconnection-java-net-cookiemanager-to-webview-android/12731212 .
public class WebkitCookieManagerProxy extends CookieManager implements CookieJar {
private android.webkit.CookieManager webkitCookieManager;
private static final String TAG = WebkitCookieManagerProxy.class.getSimpleName();
public WebkitCookieManagerProxy() {
this(null, null);
}
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)) {
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 = 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();
}
@Override
public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
HashMap<String, List<String>> generatedResponseHeaders = new HashMap<>();
ArrayList<String> cookiesList = new ArrayList<>();
for(Cookie c: cookies) {
// toString correctly generates a normal cookie string
cookiesList.add(c.toString());
}
generatedResponseHeaders.put("Set-Cookie", cookiesList);
try {
put(url.uri(), generatedResponseHeaders);
} catch (IOException e) {
Log.e(TAG, "Error adding cookies through okhttp", e);
}
}
@Override
public List<Cookie> loadForRequest(HttpUrl url) {
ArrayList<Cookie> cookieArrayList = new ArrayList<>();
try {
Map<String, List<String>> cookieList = get(url.uri(), new HashMap<String, List<String>>());
// Format here looks like: "Cookie":["cookie1=val1;cookie2=val2;"]
for (List<String> ls : cookieList.values()) {
for (String s: ls) {
String[] cookies = s.split(";");
for (String cookie : cookies) {
Cookie c = Cookie.parse(url, cookie);
cookieArrayList.add(c);
}
}
}
} catch (IOException e) {
Log.e(TAG, "error making cookie!", e);
}
return cookieArrayList;
}
}
然后在构建 OkHttpClient 时添加代理实例作为 cookieJar。
client = new OkHttpClient.Builder().cookieJar(proxy).build();
