【Android Trick 二】HTTPS请求忽略证书

现在很多网站的请求都需要使用HTTPS验证，查看google官方的HTTPS请求中可以

发现很蛋疼的会有一个keystore对象，也就是要一个证书（CA），但是如果你没有一

个有效的SSL certificate，你可能想让你的APP去忽略certificate的验证，这里将列出

两种情况下的做法：

1、HTTPSConnection

我们都知道在发送http请求时用的是HTTPConnection，但是发送https请求时使用的是

HTTPSConnection，下面看一下具体做法

首先是创建一个方法来初始化

private static void initTrustSSL() {		 try {		  SSLContext sslCtx = SSLContext.getInstance("TLS");		  sslCtx.init(null, new TrustManager[] { new X509TrustManager() {		   // do nothing, let the check pass.		   public void checkClientTrusted(X509Certificate[] chain, String authType)		      throws CertificateException {}		   public void checkServerTrusted(X509Certificate[] chain, String authType)		      throws CertificateException {}		   public X509Certificate[] getAcceptedIssuers() {		    return null;		   }		  } }, new SecureRandom());		  HttpsURLConnection.setDefaultSSLSocketFactory(sslCtx.getSocketFactory());		  HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {		   public boolean verify(String hostname, SSLSession session) {		    return true;		   }		  });

URL mURL = new URL("https://dynamic.12306.cn/otsweb/passCodeAction.do?rand=sjrand");				initTrustAllSSL();				HttpsURLConnection mConnection = (HttpsURLConnection) mURL.openConnection();

在使用封装好httpclient中需要注册https，http，如下所示

private static HttpClient createHttpClient() {         HttpParams params = new BasicHttpParams();         HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);         HttpProtocolParams.setContentCharset(params,                 HTTP.DEFAULT_CONTENT_CHARSET);         HttpProtocolParams.setUseExpectContinue(params, true);        SchemeRegistry schReg = new SchemeRegistry();         schReg.register(new Scheme("http", PlainSocketFactory                 .getSocketFactory(), 80));         schReg.register(new Scheme("https",                 SSLSocketFactory.getSocketFactory(), 443));         ClientConnectionManager conMgr = new ThreadSafeClientConnManager(                 params, schReg);        return new DefaultHttpClient(conMgr, params);     }

public static String sendData(String url, List<NameValuePair> datas) {         HttpClient client = createHttpClient();         HttpPost post = new HttpPost(url);         HttpResponse resp = null;         String result = "";         try {             post.setEntity(new UrlEncodedFormEntity(datas, HTTP.UTF_8));             resp = client.execute(post);             result = EntityUtils.toString(resp.getEntity());         } catch (UnsupportedEncodingException e) {             e.printStackTrace();         } catch (ClientProtocolException e) {             e.printStackTrace();         } catch (IOException e) {             e.printStackTrace();         }         return result;     }
