[Android实例] 关于Webview如何自动登录保存登录信息

用户名密码登录验证后保存Session

// 你的URL

HttpPost httppost = new HttpPost(Constants.ServerUrl.WEB_URL + url);

try {

List nameValuePairs = new ArrayList(2);

// Your DATA

nameValuePairs.add(new BasicNameValuePair("UserName", map

.get("UserName")));

nameValuePairs.add(new BasicNameValuePair("Password", map

.get("Password")));

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse response;

response = httpclient.execute(httppost);

if (response.getStatusLine().getStatusCode() == 200) {

// 获得响应

String result = EntityUtils.toString(response.getEntity());

// SharedPreferences preferences = context.getSharedPreferences(

// "login", Context.MODE_PRIVATE);

// Editor editor = preferences.edit();

// String handlers = "";

String cookie = "";

Date sessionTime = new Date();

List cookies = httpclient.getCookieStore().getCookies();

if (!cookies.isEmpty()) {

for (int i = 0; i < cookies.size(); i++) {

cookie = cookies.get(i).getName() + "="

+ cookies.get(i).getValue() + ";domain="

+ cookies.get(i).getDomain();

;

sessionTime = cookies.get(i).getExpiryDate();

}

}

//保存session

PersistentConfig config = new PersistentConfig(context);

config.setCookie(cookie);

config.setSessionTime(sessionTime.getTime());

// for (int i = 0; i < response.getAllHeaders().length; i++) {

// if (response.getAllHeaders().toString().contains(

// "set-cookie")) {

// handlers += response.getAllHeaders().toString();

// break;

// }

// }

//

// editor.putString("cookies",

// response.getHeaders("Set-Cookie")[0].toString());

// editor.commit();

return result;

}

} catch (ClientProtocolException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

如何在Webview请求网站时使用Session

//webview初始化的时候调用

main_view = (WebView) findViewById(R.id.main_webview);

new WebViewTask().execute();

private class WebViewTask extends AsyncTask {

String sessionCookie;

CookieManager cookieManager;

@Override

protected void onPreExecute() {

CookieSyncManager.createInstance(MainActivity.this);

cookieManager = CookieManager.getInstance();

sessionCookie = new PersistentConfig(getApplicationContext())

.getCookieString();

if (sessionCookie != null) {

// delete old cookies

cookieManager.removeSessionCookie();

}

super.onPreExecute();

}

protected Boolean doInBackground(Void... param) {

// this is very important - THIS IS THE HACK

SystemClock.sleep(1000);

return false;

}

@Override

protected void onPostExecute(Boolean result) {

if (sessionCookie != null) {

cookieManager.setCookie(Constants.ServerUrl.WEB_URL,

sessionCookie);

CookieSyncManager.getInstance().sync();

}

main_view.setScrollbarFadingEnabled(true);

main_view.getSettings().setPluginsEnabled(true);

main_view.getSettings().setPluginState(PluginState.ON);

main_view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

WebSettings webSettings = main_view.getSettings();

webSettings.setJavaScriptEnabled(true);

// 设置可以访问文件

webSettings.setAllowFileAccess(true);

// 设置支持缩放

webSettings.setBuiltInZoomControls(true);

main_view.setWebViewClient(new WebViewClient() {

@Override

public void onPageStarted(WebView view, String url,

Bitmap favicon) {

// TODO Auto-generated method stub

super.onPageStarted(view, url, favicon);

}

@Override

public void onLoadResource(WebView view, String url) {

// history();

}

});

main_view.setWebChromeClient(new WebChromeClient() {

public void onProgressChanged(WebView view, int progress) {

//Change

}

});

ShowUrlView(Constants.ServerUrl.INDEX);

}

}
