最近两天一直想用安卓模拟登陆，利用新的WebView显示登陆后可以访问的页面，但是不管怎么访问需要登陆后才能访问的页面，还是跳回到登陆页，后来网上看了下是cookie没有设置，找了半天才到到合适的设置方法：

登陆方法：

private Cookie cookie;public static  HttpContext localContext;<span style="color: rgb(255, 0, 0); "><strong>public static  List<Cookie> cookies;//此为保存的cookie</strong></span>public  String cookieStr;// public static Cookie cookie = null; /** * 登陆时保存cookie * @param url * @param data * @return */public String login(String url,String data[]){HttpClient client = null;String html = null;try {client = new DefaultHttpClient();<span style="color: rgb(255, 0, 0); "><strong>// 创建cookie store的本地实例  CookieStore cookieStore = new BasicCookieStore();  localContext = new BasicHttpContext();  // 绑定定制的cookie store到本地内容中  localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); </strong></span>HttpPost post = new HttpPost(url);List<NameValuePair> parameters = new ArrayList<NameValuePair>();parameters.add(new BasicNameValuePair("username", data[0]));parameters.add(new BasicNameValuePair("passwd", data[1]));parameters.add(new BasicNameValuePair("login", "%B5%C7%A1%A1%C2%BC"));UrlEncodedFormEntity entity = new UrlEncodedFormEntity(parameters,"utf-8");post.setEntity(entity);HttpResponse response = client.execute(post<span style="color: rgb(255, 0, 0); ">,localContext</span>);if(response.getStatusLine().getStatusCode() == 200){InputStream content = response.getEntity().getContent();BufferedReader buffer = new BufferedReader(new InputStreamReader(content,"gbk"));String line = null;while((line=buffer.readLine())!=null){html+=line;} <span style="color: rgb(255, 0, 0); "><strong> cookies = cookieStore.getCookies();</strong></span> System.out.println("cookies.size():"+cookies.size()); if (!cookies.isEmpty()) {   for(int i=0;i<cookies.size();i++){ System.out.println("- "+cookies.get(i).toString()); }  }buffer.close();}else{System.out.println("UtilsLogin:"+response.getStatusLine().getStatusCode());}} catch (Exception e) {e.printStackTrace();}finally{if(client!=null){client.getConnectionManager().shutdown();}}return html;}

Activity中的oncreate()方法：

private WebView wvTempShow;private String receiveUrl;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_temp_web_view);wvTempShow = (WebView) findViewById(R.id.wv_tempShow);Intent intent = this.getIntent();receiveUrl = intent.getStringExtra("openUrl");<span style="color: rgb(255, 0, 0); "><strong>//获得cookie管理者CookieManager cookieManager = CookieManager.getInstance();//获取登陆时的cookieString oldCookie = UtilsLogin.cookies.get(0).getName()+"="+UtilsLogin.cookies.get(0).getValue()+";"+UtilsLogin.cookies.get(1).getName()+"="+UtilsLogin.cookies.get(1).getValue()+";" ;</strong></span>System.out.println("oldCookie:"+oldCookie);cookieManager.setCookie(receiveUrl, oldCookie);wvTempShow.getSettings().setDefaultTextEncodingName("gbk");wvTempShow.loadUrl(receiveUrl);wvTempShow.setWebViewClient(new MyWebViewClient());}class MyWebViewClient extends WebViewClient{@Overridepublic void onPageStarted(WebView view, String url, Bitmap favicon) {super.onPageStarted(view, url, favicon);  }@Overridepublic void onPageFinished(WebView view, String url) {super.onPageFinished(view, url);}}

需要注意的是：要看访问的页面需要什么样的cookie字符串可以用以下方法：

CookieManager cookieManager = CookieManager.getInstance();String CookieStr = cookieManager.getCookie("http://bkjw.guet.edu.cn/student/public/menu.asp?menu=mnall.asp");            System.out.println("TempWebViewonPageFinished = " + CookieStr);

然后自己像以上String oldCookie中一样自己拼好，再在cookieManager.setCookie(url,cookieString);中设置
