將會話從Android應用程序打開到webview中的網站

Question

我有一個我正在創建的Android應用程序，並且我有一個登錄頁面作爲第一個意圖。然後這將打開一個標籤持有人，並將用戶帶到第一個標籤，它將顯示一個webview。該網站是應用程序的重要組成部分，並要求用戶登錄。網站和應用程序使用相同的登錄腳本，該腳本從同一服務器運行，因此登錄信息相同。我想使用在webview中登錄應用程序時創建的會話，以便當用戶轉到webview時他們仍然登錄。我嘗試使用共享首選項在webview上重新登錄，但這不是加工。我能夠將共享首選項傳遞給它，但它仍然告訴我我沒有登錄到網站上。任何有關這個話題的幫助將不勝感激。

這裏是我的代碼：

Connection類創建defaultHttpRequest，我將所有的類之間傳遞。

import java.io.IOException; 

import org.apache.http.HttpResponse; 
import org.apache.http.client.ClientProtocolException; 
import org.apache.http.client.HttpClient; 
import org.apache.http.client.entity.UrlEncodedFormEntity; 
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.DefaultHttpClient; 

public class Connection1 { 


    public static HttpClient httpclient = new DefaultHttpClient(); 
    private static HttpPost httpPost; 

    public Connection1(){ 
    } 

    public HttpPost getHttpPost(){ 
     return httpPost; 
    } 
    public HttpResponse getResponse() throws ClientProtocolException, IOException{ 
     return httpclient.execute(httpPost); 
    } 
    public void setEntity(UrlEncodedFormEntity entity){ 
     httpPost.setEntity(entity); 
    } 
    public void setHttpPost(String script){ 
     httpPost = new HttpPost(script); 
    } 
} 

的webapp類，將顯示網站頁面：

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 org.apache.http.NameValuePair; 
import org.apache.http.client.ClientProtocolException; 
import org.apache.http.client.entity.UrlEncodedFormEntity; 
import org.apache.http.message.BasicNameValuePair; 

import android.app.Activity; 
import android.content.SharedPreferences; 
import android.os.Bundle; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 

public class WebApp extends Activity { 

    public static final String PREFS_NAME = "myPrefsFile"; 
    private static final String PREFS_USERNAME = "username"; 
    private static final String PREFS_PASSWORD = "password"; 

    String username = ""; 
    String password = ""; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
    } 

    @Override 
    protected void onResume() { 
     // TODO Auto-generated method stub 
     super.onResume(); 
     setContentView(R.layout.webapp); 
     SharedPreferences pref = getSharedPreferences(PREFS_NAME, MODE_PRIVATE); 
     username = pref.getString(PREFS_USERNAME, null); 
     password = pref.getString(PREFS_PASSWORD, null); 
     System.out.println(username + "-" + password); 
     postLoginData(); 


    } 

    public void postLoginData() { 

     // Create a new HttpClient and Post Header 
     Connection1 connection = new Connection1(); 
     connection 
       .setHttpPost("script.php"); 

     try { 

      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
      nameValuePairs.add(new BasicNameValuePair("username", username)); 
      nameValuePairs.add(new BasicNameValuePair("password", password)); 
      connection.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

      String str = inputStreamToString(
        connection.getResponse().getEntity().getContent()) 
        .toString(); 

      if (str.toString().equalsIgnoreCase("success")) { 
       WebView webapp = (WebView) findViewById(R.id.webView1); 
       webapp.loadUrl("URL"); 
       webapp.setWebViewClient(new WebViewClient()); 
       webapp.getSettings().setJavaScriptEnabled(true); 
      } 
     } catch (ClientProtocolException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 

    private StringBuilder 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) { 
      e.printStackTrace(); 
     } 
     // Return full string 
     return total; 
    } 
} 

Answer 1

在您的WebView實例，調用此。

webView.setHttpAuthUsernamePassword(url,"", "@"+username, password); 

，並覆蓋下面的方法：

@Override 
public boolean shouldOverrideUrlLoading(WebView view, String url) { 
    view.loadUrl(url+"?name="+username+"&password="+password); 
    view.loadUrl(url); 
    return true; 
} 

Answer 2

webView = (WebView) findViewById(R.id.webview); 
webView.clearCache(true); 
WebViewDatabase.getInstance(this).clearHttpAuthUsernamePassword(); 
webView.setWebViewClient(new PasswordWebViewClient()); 
webView.getSettings().setJavaScriptEnabled(true); 

public class PasswordWebViewClient extends WebViewClient { 

    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
     //view.loadUrl(url+"?name="+username+"&password="+password); 
     view.loadUrl(url); 

     //webView.loadUrl("https://www.google.com/accounts/ServiceLoginAuth? continue=http://mail.google.com/gmail&service=mail&Email=username&Passwd=password&null=Sign+in"); 

     return true; 
    } 

    public void onReceivedHttpAuthRequest (WebView view, 
     HttpAuthHandler handler, String host, String realm){ 
     System.out.println("Entered into onReceivedHttpAuthRequest"); 

     handler.proceed(username, password); 
    } 

    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
     Toast.makeText(getApplicationContext(), description, Toast.LENGTH_SHORT).show(); 
    } 

}
