Question

您好，不确定我要问什么，因为我之前没有使用过Cookie。在我的应用程序中，我正在打开一个WebView，我们提交了一些数据，我想存储cookie，那样，当我关闭WebView（也要关闭app）并重新打开它时，它将使用存储的cookie。

我不太喜欢我的代码，因为我一直在关注示例。

@Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            ProgressBar progressBar = (ProgressBar) 
findViewById(R.id.progress_bar);
            progressBar.setIndeterminate(true);
            progressBar.setVisibility(View.VISIBLE);
            super.onPageStarted(view, url, favicon);
            String cookieStr = CookieManager.getInstance().getCookie(url);
            try {
                storeCookies(url, cookieStr);
            } catch (URISyntaxException e) {
                e.printStackTrace();
            }


        }

        private void storeCookies(String url, String cookieString) throws URISyntaxException {
            if (cookieString !=null &&  !cookieString.isEmpty()) {
                URI uri = new URI(url);
                List<HttpCookie> cookies = HttpCookie.parse(cookieString);
                for (HttpCookie cookie : cookies) {
                    cookieStore = new CookieStore() {
                        @Override
                        public void add(URI uri, HttpCookie cookie) {
                            cookieStore.add(uri, cookie);
                        }


                        @Override
                        public List<HttpCookie> get(URI uri) {
                            return null;
                        }

                        @Override
                        public List<HttpCookie> getCookies() {
                            return null;
                        }

                        @Override
                        public List<URI> getURIs() {
                            return null;
                        }

                        @Override
                        public boolean remove(URI uri, HttpCookie cookie) {
                            return false;
                        }

                        @Override
                        public boolean removeAll() {
                            return false;
                        }
                    };

                }
            }
        }

        public void onPageFinished(WebView view, String url) {
            ProgressBar progressBar = (ProgressBar)findViewById(R.id.progress_bar);
            progressBar.setVisibility(View.GONE);
            setURL(url);

        }
    });
}

如果您要设置网站的Cookie，请遵循以下代码。

科特琳：

val cookieManager = CookieManager.getInstance()
cookieManager.setAcceptCookie(true)
cookieManager.setCookie("YOUR_WEBSITE_URL", "key=value")
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
   val cookieSyncManager = CookieSyncManager.createInstance(this)
   cookieSyncManager.sync()
}

Java：

CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
cookieManager.setCookie("YOUR_WEBSITE_URL", "key=value");
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
   CookieSyncManager cookieSyncManager = CookieSyncManager.createInstance(this);
   cookieSyncManager.sync();
}

将 YOUR_WEBSITE_URL 替换为您的网站url，并将 key = value 与值配对。希望这会有所帮助。
