安卓同步WebView和HttpClient的Cookies

安卓同步WebView和HttpClient的Cookies

androidcookieswebviewhttpclient

4

我有一个登录webview和httpclient，需要确认用户是否已登录。问题在于webview和httpclient使用其他Cookie，因此httpclient无法获取webview Cookie。

我阅读了很多人的问题和教程，但没有什么用。其中一些内容如下：

我还阅读了一些关于Android开发和其他网站的教程，但没有什么用。

另一个帖子：https://stackoverflow.com/questions/28052461/syncing-webview-with-httpclient 问题在于Cookie无法同步。 我尝试过以下方法：

        WebView webview;
        webview = (WebView) rootView.findViewById(R.id.webview);

        webview.setWebViewClient(new WebViewClient() {
            public void onPageFinished(WebView view, String url) {
                CookieSyncManager.getInstance().sync();

            }
        });
        webview.getSettings().setDomStorageEnabled(true);
        webview.getSettings().setJavaScriptEnabled(true);
        webview.getSettings().setUseWideViewPort(true);
        webview.setWebChromeClient(new WebChromeClient());
        webview.loadUrl("http://www.klh-dev.com/lehava/lehava/system/mlogin.php");

还有一些内容：

   public String IsLoggedIn() {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    HttpClient client=new DefaultHttpClient();



                    HttpGet get=new HttpGet(url);
                     ResponseHandler<String> responseHandler = new BasicResponseHandler();
                    try {
                        response_str=client.execute(get,responseHandler);
                        System.out.println(response_str);
                    } catch (ClientProtocolException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    Cookie sessionInfo;
                    List<Cookie> cookies = client.getCookieStore().getCookies();

                    if (! cookies.isEmpty()){
                            CookieSyncManager.createInstance(getApplicationContext());
                            CookieManager cookieManager = CookieManager.getInstance();

                            for(Cookie cookie : cookies){
                                    sessionInfo = cookie;
                                    String cookieString = sessionInfo.getName() + "=" + sessionInfo.getValue() + "; domain=" + sessionInfo.getDomain();
                                    cookieManager.setCookie(URLn, cookieString);
                                    CookieSyncManager.getInstance().sync();
                            }
                    }
                }
            }).start();
            return response_str;
   }

我想从Webview中获取Cookie并在我的HttpClient请求中使用它们

编辑（添加darpan的答案）：

    public static BasicCookieStore getCookieStore(String cookies, String domain) {
        String[] cookieValues = cookies.split(";");
        BasicCookieStore cs = new BasicCookieStore();

        BasicClientCookie cookie;
        for (int i = 0; i < cookieValues.length; i++) {
            String[] split = cookieValues[i].split("=");
            if (split.length == 2)
                cookie = new BasicClientCookie(split[0], split[1]);
            else
                cookie = new BasicClientCookie(split[0], null);

            cookie.setDomain(domain);
            cs.addCookie(cookie);
        }
        return cs;

        }

    public String IsLoggedIn() {
        new Thread(new Runnable() {
            @Override
            public void run() {




                     String cookies = CookieManager.getInstance().getCookie("http://klh-dev.com/lehava/lehava/system/isloggedin.php");
                     BasicCookieStore lCS = getCookieStore(cookies, "klh-dev.com");

                     HttpContext localContext = new BasicHttpContext();
                     DefaultHttpClient httpclient = new DefaultHttpClient();
                     httpclient.setCookieStore(lCS);
                     localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);

                HttpGet get=new HttpGet("http://klh-dev.com/lehava/lehava/system/isloggedin.php");
                 ResponseHandler<String> responseHandler = new BasicResponseHandler();



                try {
                    result=httpclient.execute(get,localContext);
                    response_str = EntityUtils.toString(result.getEntity());
                    System.out.println(response_str);
                } catch (ClientProtocolException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }


            }
        }).start();
        return response_str;
    }
}

编辑2：终于成功了！！ 这是我的代码：

public static String IsLoggedIn() {
    new Thread(new Runnable() {
        @Override
        public void run() {
                 String cookies = CookieManager.getInstance().getCookie(getUrl);
                 BasicCookieStore lCS = getCookieStore(cookies, "klh-dev.com");

                 HttpContext localContext = new BasicHttpContext();
                 DefaultHttpClient httpclient = new DefaultHttpClient();
                 httpclient.setCookieStore(lCS);
                 localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);

            HttpGet get = new HttpGet("http://klh-dev.com/lehava/lehava/system/isloggedin.php");


            try {
                result=httpclient.execute(get,localContext);
                response_str = EntityUtils.toString(result.getEntity());
                System.out.println(response_str);
                ((MainActivity) getContext).UpdateMenu();
            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
    }).start();
    return response_str;
}

关于getUrl变量。我不得不设置一个全局变量，像这样：

private static String getUrl;

public String getUrl() {
    return getUrl;
}

在每个片段中，我都需要添加onPageFinished：getUrl = view.getUrl();。

谢谢。

在您的代码中，您似乎正在做与您所希望的相反的事情（从Webview获取cookie并在HttpClient中设置）。 编辑：来自Mor Haviv的答案 - 您需要定义一个全局变量，在视图中存储当前url -

private static String getUrl;

从webview获取cookie -

@Override
public void onPageFinished(WebView view, String url){
    getUrl = view.getUrl();
    String cookies = CookieManager.getInstance().getCookie(getUrl);
    Log.d(TAG, "All the cookies in a string:" + cookies);
}

上述代码的参考

将名为“cookies”的字符串设置在你的 HttpClient 中 -

public static BasicCookieStore getCookieStore(String cookies, String domain) {
String[] cookieValues = cookies.split(";");
BasicCookieStore cs = new BasicCookieStore();

BasicClientCookie cookie;
for (int i = 0; i < cookieValues.length; i++) {
    String[] split = cookieValues[i].split("=");
    if (split.length == 2)
        cookie = new BasicClientCookie(split[0], split[1]);
    else
        cookie = new BasicClientCookie(split[0], null);

    cookie.setDomain(domain);
    cs.addCookie(cookie);
}
return cs;

}
 //And, use the same 'getUrl' here to fetch the cookie. (Haviv's addition)
 String cookies = CookieManager.getInstance().getCookie(getUrl);
 BasicCookieStore lCS = getCookieStore(cookies, YOUR_APP_DOMAIN);

 HttpContext localContext = new BasicHttpContext();
 DefaultHttpClient httpclient = new DefaultHttpClient();
 httpclient.setCookieStore(lCS);
 localContext.setAttribute(ClientContext.COOKIE_STORE, lCS);

PS - 在'YOUR_APP_DOMAIN'处填写你的应用程序域名。同时，由于没有你的域名，我无法检查代码。
