android okvolley框架搭建

最近新出了很多好东西都没时间去好好看看，现在得好好复习下了，记下笔记

记得以前用的框架是android-async-http，volley啊，或者其它的，然后后面接着又出了okhttp，retrofit，rxjava很多新东西，有句话说的好啊，我不是程序员，我只是github上面的搬运工，出了这么多东西肯定会有很多人学习然后发表文章的，自己就去学习了下，因为以前用的是volley，所以就没去用retrofit了，因为volley也支持okhttp了，至于为什么要用okhttp就不多说了，毕竟不是大牛，只供小白学习，代码就是最好的老师啊，接下来就是用的okhttp和volley结合使用的框架体了。

接口请求类

 public class OkVolleyService {

     public interface ClientCallback {
         void onSuccess(Object data);

         void onFailure(Exception e);

         void onError(Exception e);
     }

     public static void Login(String userID, String password, Context context,
                              final ClientCallback callback) {

         String token = AuthFactory.encryptPassword(userID);
         Map<String, String> params = new HashMap<>();
         params.put("token", token);
         params.put("userName", userID);
         params.put("userPassword", password);
         RequestManager.PostString("/doctor/login.do", context, params,
                 new Response.Listener<String>() {
                     @Override
                     public void onResponse(String response) {
                         UsersEntity entity = null;
                         try {
                             entity = UsersEntity.parse(response);
                         } catch (Exception e) {
                             e.printStackTrace();
                             callback.onError(e);
                         }
                         callback.onSuccess(entity);
                     }
                 }, new Response.ErrorListener() {
                     @Override
                     public void onErrorResponse(VolleyError error) {
                         callback.onFailure(error);
                     }
                 });

     };

 }

支持https和网络请求类

public class HTTPSTrustManager implements X509TrustManager{
    private static TrustManager[] trustManagers;
    private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[] {};

    @Override
    public void checkClientTrusted(
            java.security.cert.X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {
        // To change body of implemented methods use File | Settings | File
        // Templates.
    }

    @Override
    public void checkServerTrusted(
            java.security.cert.X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {
        // To change body of implemented methods use File | Settings | File
        // Templates.
    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return true;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return _AcceptedIssuers;
    }

    public static void allowAllSSL() {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                // TODO Auto-generated method stub
                return true;
            }

        });

        SSLContext context = null;
        if (trustManagers == null) {
            trustManagers = new TrustManager[] { new HTTPSTrustManager() };
        }

        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
        HttpsURLConnection.setDefaultSSLSocketFactory(context
                .getSocketFactory());
    }

}

/**

public class SelfSignSslOkHttpStack extends HurlStack {

    private OkHttpClient okHttpClient;

        if ("http".equals(url.getProtocol())) {//如果请求是https请求那么就信任所有SSL,此处作了修改，无论是不是https都信任

            HttpURLConnection connection = new OkUrlFactory(okHttpClient).open(url);
//            SSLSocketFactory ssl = HTTPSTrustManager.allowAllSSL();

            return connection;
        } else {
            return new OkUrlFactory(okHttpClient).open(url);
        }
    }

}

请求管理类

    private static int SOCKET_TIMEOUT = 6 * 10 * 100;
    private static RequestManager instance;

    private Map<String, SSLSocketFactory> socketFactoryMap;

    }

        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, tmf.getTrustManagers(), new SecureRandom());
        return sslContext.getSocketFactory();
    }

学习笔记，只供参考，此处还可以优化，比如把网络回调去掉，改用rxandroid
