我通过OKHttpClient帖子以用户身份登录，我想与webview共享cookie。
答案 0 :(得分：10)
使用OkHttp 3.0，您可以使用类似于与HttpURLConnection共享的方法，方法是创建使用webkit cookie存储的WebkitCookieManagerProxy。改编自Pass cookies from HttpURLConnection (java.net.CookieManager) to WebView (android.webkit.CookieManager)。
client = new OkHttpClient.Builder().cookieJar(proxy).build();
然后在构建OkHttpClient时添加代理实例作为cookieJar。

此链接有所帮助，但我必须为我的用例修改一些内容：http://artemzin.com/blog/use-okhttp-to-load-resources-for-webview/
以下代码有效：
webView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
//enable javascript...
webSettings.setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progress.dismiss();
}
@SuppressWarnings("deprecation")
@Override
public WebResourceResponse shouldInterceptRequest(@NonNull WebView view, @NonNull String url) {
return handleRequestViaOkHttp(url);
}
});
webView.loadUrl("MY_URL.COM");
然后执行基本身份验证的代码+使用OkHTTPClient处理拦截webview请求。
@NonNull
private WebResourceResponse handleRequestViaOkHttp(@NonNull String url) {
try {
OkHttpClient client = new OkHttpClient();
client.setAuthenticator(new Authenticator() {
//for basic authorization...
@Override
public Request authenticate(Proxy proxy, com.squareup.okhttp.Response response) throws IOException {
String credential = Credentials.basic(CommonResource.HEADER_USERNAME, CommonResource.HEADER_PASSWORD);
return response.request().newBuilder().header("Authorization", credential).build();
}
@Override
public Request authenticateProxy(Proxy proxy, com.squareup.okhttp.Response response) throws IOException {
return null;
}
});
final Call call = client.newCall(new Request.Builder()
.url(url)
.build()
);
final Response response = call.execute();
return new WebResourceResponse("text/html", "UTF-8", response.body().byteStream());
} catch (Exception e) {
e.printStackTrace();
return null;
}
}

如果您只关心OkHttp + WebView，那么它可能会像这样简单：
class WebkitCookieManager (private val cookieManager: CookieManager) : CookieJar {
override fun saveFromResponse(url: HttpUrl, cookies: List<Cookie>) {
cookies.forEach { cookie ->
cookieManager.setCookie(url.toString(), cookie.toString())
}
}
override fun loadForRequest(url: HttpUrl): List<Cookie> =
when (val cookies = cookieManager.getCookie(url.toString())) {
null -> emptyList()
else -> cookies.split("; ").mapNotNull { Cookie.parse(url, it) }
}
}
....
Usage:
1. OkHttp
OkHttpClient.Builder().cookieJar(webkitCookieManager)
2. WebView
CookieManager.getInstance().setCookie()
如果不使用HttpURLConnection，则无需支持。
