Question

如何在DefaultHttpClient和WebView之間共享cookie？

Answer 1

用戶解決了在DefaultHttpClient和WebView之間共享Cookie的問題。 This solution worked for him，所以他想在那裏分享完整的代碼。

LoginActivity.java，核心代號爲doPost方法：

private int mNumber = 3; 
public InputStream doPost(String url, HashMap<String, String> params, 
     String headParam, ArrayList<String> keyValues) { 

    DefaultHttpClient httpClient = null; 
    InputStream inputStream = null; 
    HttpResponse httpResponse = null; 
    int statusCode = -1; 

    httpClient = (DefaultHttpClient) NetworkManager.getHttpClient(); 
    HttpPost httpPost = new HttpPost(url); 

    if (headParam != null) { 
     httpPost.addHeader("Cookie", headParam); 
    } 

    if (params != null) { 

     List<NameValuePair> httpRequestParams = new ArrayList<NameValuePair>(); 
     Iterator<Entry<String, String>> iter = params.entrySet().iterator(); 
     while (iter.hasNext()) { 

      Map.Entry<String, String> entry = iter.next(); 
      String key = entry.getKey(); 
      String val = entry.getValue(); 
      if (val.equals("multi")) { 

       for (String values : keyValues) 
        httpRequestParams.add(new BasicNameValuePair(key, 
          values)); 
      } else 
       httpRequestParams.add(new BasicNameValuePair(key, val)); 
     } 

     try { 
      httpPost.setEntity(new UrlEncodedFormEntity(httpRequestParams, 
        HTTP.UTF_8)); 
     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); 
     } 
    } 

    try { 
     httpResponse = httpClient.execute(httpPost); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
     httpPost.abort(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
     httpPost.abort(); 
     if (mNumber >= 1) { 
      mNumber--; 
      doPost(url, params, headParam, keyValues); 
      return null; 
     } 
    } 

    if (httpResponse != null) { 
     statusCode = httpResponse.getStatusLine().getStatusCode(); 
     if (statusCode == HttpURLConnection.HTTP_OK) { 
      try { 
       inputStream = httpResponse.getEntity().getContent(); 
      } catch (IllegalStateException e) { 
       e.printStackTrace(); 
       httpPost.abort(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } else { 
      if (mNumber >= 1) { 
       mNumber--; 
       doPost(url, params, headParam, keyValues); 
      } else { 
      } 
     } 
    } else { 
     if (mNumber >= 1) { 
      mNumber--; 
      doPost(url, params, headParam, keyValues); 
     } 
    } 

    Config.mCookies = httpClient.getCookieStore().getCookies(); //save cookies 
    return inputStream; 
} 

在Config.java：

public static List<Cookie> mCookies = null; 

成功登錄後，網頁視圖瀏覽：

List<Cookie> cookies = Config.mCookies; 
    if (cookies != null && !cookies.isEmpty()) { 

     CookieSyncManager.createInstance(mContext); 
     CookieManager cookieManager = CookieManager.getInstance(); 
     for (Cookie cookie : cookies) { 

      Cookie sessionInfo = cookie; 
      String cookieString = sessionInfo.getName() + "=" 
        + sessionInfo.getValue() + "; domain=" 
        + sessionInfo.getDomain(); 
      cookieManager.setCookie("http://stackoverflow.com", cookieString); 
      CookieSyncManager.getInstance().sync(); 
     } 
    } 
    mWebview.loadUrl(mLink); 
    setCookie(url, string); 

的網址需要主機，起初他只使用域（例如，stackoverflow.com），但它不起作用。它也必須包含主機（例如，http://stackoverflow.com）。
