Question

我想通过我的网页浏览中的帖子登录网站。这工作正常，但如果我点击这个网站上的按钮，我会被重定向回登录页面。如何保存登录信息，以便我再次登录？我应该使用cookies来解决问题吗？我已经尝试过使用cookies，但这并没有解决问题。

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    CookieSyncManager.createInstance(MainActivity.this);
    CookieSyncManager.getInstance().sync();

}

private class LoadWebPageASYNC extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... urls) {
        String result = "";


            // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost("http://example/index.php?s=login");

            try {
                CookieManager cookieManager = CookieManager.getInstance();
                cookieManager.setAcceptCookie(true);

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
                nameValuePairs.add(new BasicNameValuePair("id", "id"));
                nameValuePairs.add(new BasicNameValuePair("pass", "pass"));
                nameValuePairs.add(new BasicNameValuePair("submit", "login"));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));


                // Execute HTTP Post Request
                HttpResponse response = httpclient.execute(httppost);
                HttpEntity entity = response.getEntity();
                result = EntityUtils.toString(entity, "UTF-8");


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



        return result;
    }




    @Override
    protected void onPostExecute(String result) {

        WebView webView = (WebView) findViewById(R.id.webView);
        webView.setWebViewClient(new WebViewClient());
        webView.getSettings().setJavaScriptEnabled(true);
        CookieManager.setCookie(); 
        webView.loadDataWithBaseURL("http://example/index.php?s=login", result, "text/html", "BASE64", null);

    }
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
}

public void dummyFunc(View view){
    Toast.makeText(MainActivity.this, "Button works", Toast.LENGTH_SHORT).show();

}

public void readWebpage(View view) {
    LoadWebPageASYNC task = new LoadWebPageASYNC();
    task.execute(new String[] { "http://example/index.php?s=login" });

}

}

是的，你必须使用cookie。

在Android中发送POST数据并更改站点
