Question

经过许多小时，我设法弄清楚如何在我的httpclient和我的webview之间共享cookie。我现在的问题是，由于某种原因，我的会话cookie没有被共享。

在android文档中我发现： public void setCookie（String url，String value）自：API级别1 为给定的URL设置cookie。将删除具有相同主机/路径/名称的旧cookie。 如果新Cookie未过期或未过期且意味着它是会话Cookie，则会添加新Cookie。

事情是我共享一个已设置到期的cookie并且它有效。任何人都有任何想法为什么我的会话cookie没有被共享，或者实际上是因为setCookie无法做到这一点，我怎么能以不同的方式做到这一点。

这是我的代码：

    package mds.test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

import android.webkit.WebViewClient;

public class Home extends Activity {



    public static final String LOG_TAG = "Droidnova";

    private class HelloWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }

    private String tmDevice;
    private String sid;
    private String url;
    public static Cookie cookie = null;


    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        CookieSyncManager.createInstance(this);
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setAcceptCookie(true);

        final TelephonyManager tm = (TelephonyManager) getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);
        tmDevice = "blabla" + tm.getDeviceId();

        postData();

        url = "mywebsite="+sid.substring(5); 

        Log.d(LOG_TAG, "cookie value: " + cookie);

        if (cookie != null) {
            cookieManager.removeSessionCookie();
            String cookieString = cookie.getName() + "=" + cookie.getValue() + "; domain=" + cookie.getDomain();
            cookieManager.setCookie(cookie.getDomain(), cookieString);
            CookieSyncManager.getInstance().sync();
        }

        setContentView(R.layout.web);
        WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.setWebViewClient(new HelloWebViewClient());
        myWebView.loadUrl(url);
    }

    public void postData() {
        // Create a new HttpClient and Post Header
        DefaultHttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("my website");

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("uid", tmDevice));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

            inputStreamToString(response.getEntity().getContent());


            List<Cookie> cookies = httpclient.getCookieStore().getCookies();
            if (!cookies.isEmpty()) {
                for (int i = 0; i < cookies.size(); i++) {
                    cookie = cookies.get(i);
                }
            }

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }

   }

    private void inputStreamToString(InputStream is) {
        String line = "";
        StringBuilder total = new StringBuilder();

        // Wrap a BufferedReader around the InputStream
        BufferedReader rd = new BufferedReader(new InputStreamReader(is));

        // Read response until the end
        try {
            while ((line = rd.readLine()) != null) { 
                total.append(line); 
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        sid = total.toString();         
    }

}

请注意，这不是一个解决方案，只要您可以访问该页面的代码，它就是一种解决方法。

您可以传递Cookie的POST值，而不是将Cookie传递给webView：

String postData = cookie.getName() + "=" + cookie.getValue();
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new HelloWebViewClient());
myWebView.postUrl(loadUrl,EncodingUtils.getBytes(postData, "BASE64") );

在授权机制的网站上，您必须检查POST数据以及会话。

会话cookie未被共享
