HttpClient和OkHttp关于Https请求问题

项目中遇到登录接口，使用的时https接口，所以客户端必须要进行配置，原先的项目使用的时Apache的Httpclient，Android的api接口也内置了httpclient，但是Android系统在4.x以后不建议使用了Httpclient，推荐使用urlconnection，但是urlconnection毕竟太过于原始，所以我选择了okhttp作为http请求库。

OKhttp的地址

由于服务器使用的是通用的https加密，所以我在这里只是介绍通用的加密方式。

Httpclient

    static class SSLSocketFactoryEx extends SSLSocketFactory {            SSLContext sslContext = SSLContext.getInstance("TLS");            public SSLSocketFactoryEx(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {              super(truststore);                TrustManager tm = new X509TrustManager() {                  public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {                  }                    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {                  }                    public X509Certificate[] getAcceptedIssuers() {                      return null;                  }              };                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();          }      }            static HttpClient getNewHttpClient() {          try {              KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());              trustStore.load(null, null);                SSLSocketFactoryEx sf = new SSLSocketFactoryEx(trustStore);              sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);                HttpParams params = new BasicHttpParams();              HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);              HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);                SchemeRegistry registry = new SchemeRegistry();              registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));              registry.register(new Scheme("https", sf, 443));                ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);                return new DefaultHttpClient(ccm, params);          } catch (Exception e) {              return new DefaultHttpClient();          }      }

OkHttp

    static class HttpStackPlus extends HurlStack {          private final OkUrlFactory mFactory;            public HttpStackPlus() {              this(new OkHttpClient());          }            public HttpStackPlus(OkHttpClient client) {              if (client == null) {                  throw new NullPointerException("Client must not be null.");              } else {                  try {                      TrustManager tm = new X509TrustManager() {                          public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {                          }                            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {                          }                            public X509Certificate[] getAcceptedIssuers() {                              return null;                          }                      };                        SSLContext e = SSLContext.getInstance("TLS");                        e.init(null, new TrustManager[]{tm}, null);                        client.setSslSocketFactory(e.getSocketFactory());                    } catch (Exception e) {                      throw new AssertionError();                  }                    this.mFactory = new OkUrlFactory(client);              }          }            protected HttpURLConnection createConnection(URL url) throws IOException {              return this.mFactory.open(url);          }      }        public static RequestQueue newRequestQueue(Context context) {          return Volley.newRequestQueue(context, new HttpStackPlus());      }
