开源库android-async-http添加https请求方式

这几天由于项目要求将http转换成https请求，要求不做证书验证。而我使用的是loopj的开源库android-async-http来完成服务器请求，但是此库并未有相关https的示例，故自己动手丰衣足食。
经过一番摸索，现记录如下：

封装了一个httpclient帮助类，以此获取一个DefaultHttpClient的示例对象。

   private static final String VERSION = "1.1";    /** http请求最大并发连接数 */    private static final int DEFAULT_MAX_CONNECTIONS = 10;    /** 超时时间，默认10秒 */    private static final int DEFAULT_SOCKET_TIMEOUT = 30 * 1000;    /** 默认的套接字缓冲区大小 */    private static final int DEFAULT_SOCKET_BUFFER_SIZE = 8192;    private static int maxConnections = DEFAULT_MAX_CONNECTIONS;    private static int socketTimeout = DEFAULT_SOCKET_TIMEOUT;    private HttpClientHelper() {    }    public static synchronized DefaultHttpClient getHttpClient() {        if (null == httpClient) {            // 初始化工作            try {                KeyStore trustStore = KeyStore.getInstance(KeyStore                        .getDefaultType());                trustStore.load(null, null);                BasicHttpParams httpParams = new BasicHttpParams();                ConnManagerParams.setTimeout(httpParams, socketTimeout);                ConnManagerParams.setMaxConnectionsPerRoute(httpParams,                        new ConnPerRouteBean(maxConnections));                ConnManagerParams.setMaxTotalConnections(httpParams,                        DEFAULT_MAX_CONNECTIONS);                HttpConnectionParams.setSoTimeout(httpParams, socketTimeout);                HttpConnectionParams.setConnectionTimeout(httpParams,                        socketTimeout);                HttpConnectionParams.setTcpNoDelay(httpParams, true);                HttpConnectionParams.setSocketBufferSize(httpParams,                        DEFAULT_SOCKET_BUFFER_SIZE);                HttpProtocolParams.setVersion(httpParams, HttpVersion.HTTP_1_1);                HttpProtocolParams.setUserAgent(httpParams, String                        .format("thinkandroid/%s (http://www.thinkandroid.cn)",                                VERSION));                // 设置 https支持                SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);                sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); // 允许所有主机的验证                SchemeRegistry schReg = new SchemeRegistry();                schReg.register(new Scheme("http", PlainSocketFactory                        .getSocketFactory(), 80));                schReg.register(new Scheme("https", sf, 443));                schReg.register(new Scheme("https", sf, 8443));                ClientConnectionManager conManager = new ThreadSafeClientConnManager(                        httpParams, schReg);                httpClient = new DefaultHttpClient(conManager, httpParams);            } catch (Exception e) {                e.printStackTrace();                return new DefaultHttpClient();            }        }        return httpClient;    }}class SSLSocketFactoryEx extends SSLSocketFactory {    SSLContext sslContext = SSLContext.getInstance("TLS");    public SSLSocketFactoryEx(KeyStore truststore)            throws NoSuchAlgorithmException, KeyManagementException,            KeyStoreException, UnrecoverableKeyException {        super(truststore);        TrustManager tm = new X509TrustManager() {            @Override            public java.security.cert.X509Certificate[] getAcceptedIssuers() {                return null;            }            @Override            public void checkClientTrusted(                    java.security.cert.X509Certificate[] chain, String authType)                    throws java.security.cert.CertificateException {            }            @Override            public void checkServerTrusted(                    java.security.cert.X509Certificate[] chain, String authType)                    throws java.security.cert.CertificateException {            }        };        sslContext.init(null, new TrustManager[] { tm }, null);    }    @Override    public Socket createSocket(Socket socket, String host, int port,            boolean autoClose) throws IOException, UnknownHostException {        return sslContext.getSocketFactory().createSocket(socket, host, port,                autoClose);    }    @Override    public Socket createSocket() throws IOException {        return sslContext.getSocketFactory().createSocket();    }}

然后在开源库的AsyncHttpClient类中将原来的 httpClient = new DefaultHttpClient(cm, httpParams)替换成httpClient = HttpClientHelper.getHttpClient()即可。

这个封装类大家可以拿去用的。只要是不做证书验证。如果需要加载证书验证的，对客户端来说比较简单。可以去google下。
