android Retrofit 配置https证书

使用环境：

       1 不愿项目数据外泄使用了https，

       2 讲cer证书转换成了bks文件，并存放只assets文件下

       3 

       if ( 联网方法不是retrofit  2.0 以上）{

            return；

       }

       其他没什么限制，这篇也就是特例特讲。

使用方法：

  OkHttpClient sOkHttpClient = new OkHttpClient.Builder()
                .cookieJar(new CookieJarImpl(new PersistentCookieStore(Utils.getContext())))
                .addInterceptor(new BaseInterceptor(headers))
                .addInterceptor(new CacheInterceptor(Utils.getContext()))
                .addInterceptor(new LoggingInterceptor
                        .Builder()//构建者模式
                        .loggable(BuildConfig.DEBUG) //是否开启日志打印
                        .setLevel(Level.BASIC) //打印的等级
                        .log(Platform.INFO) // 打印类型
                        .request("Request") // request的Tag
                        .response("Response")// Response的Tag
                        .addHeader("log-header", "I am the log request header.") // 添加打印头, 注意 key 和 value 都不能是中文
                        .build()
                )
                .connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)
                .writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)
                .readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)
                .connectionPool(new ConnectionPool(3, 2, TimeUnit.MINUTES))
                .build();

        HostnameVerifier hv1 = new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };

        //通过反射拿到okhttpClient 对象，给sslParams的SSLSocketFactory赋值
        String workerClassName = "okhttp3.OkHttpClient";
        try {
            Class workerClass = Class.forName(workerClassName);
            Field hostnameVerifier = workerClass.getDeclaredField("hostnameVerifier");
            hostnameVerifier.setAccessible(true);
            hostnameVerifier.set(sOkHttpClient, hv1);
                
            Field sslSocketFactory = workerClass.getDeclaredField("sslSocketFactory");
            sslSocketFactory.setAccessible(true);
            //主要就是这一步
            //utils.getContext() 就是当前上下文对象
            //SSLSocketFactoryUtils代码在下面            sslSocketFactory.set(sOkHttpClient,SSLSocketFactoryUtils.getSSLSocketFactory(Utils.getContext()));
        } catch (Exception e) {
            e.printStackTrace();
        }

        retrofit = new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .baseUrl(url)
                .client(sOkHttpClient)
                .build();

SSLSocketFactoryUtils代码：

public class SSLSocketFactoryUtils {

    /**
     * 获取bks文件的sslsocketfactory
     *
     * @param context
     * @return
     */
    public static SSLSocketFactory getSSLSocketFactory(Context context) {
        final String CLIENT_TRUST_PASSWORD = "123456";//信任证书密码，该证书默认密码是123456
        final String CLIENT_AGREEMENT = "TLS";//使用协议
        final String CLIENT_TRUST_KEYSTORE = "BKS";
        SSLContext sslContext = null;
        try {
            //取得SSL的SSLContext实例
            sslContext = SSLContext.getInstance(CLIENT_AGREEMENT);
            //取得TrustManagerFactory的X509密钥管理器实例
            TrustManagerFactory trustManager = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
            //取得BKS密库实例
            KeyStore tks = KeyStore.getInstance(CLIENT_TRUST_KEYSTORE);
            InputStream is = context.getResources().openRawResource(R.raw.shiqin);
            try {
                tks.load(is, CLIENT_TRUST_PASSWORD.toCharArray());
            } finally {
                is.close();
            }
            //初始化密钥管理器
            trustManager.init(tks);
            //初始化SSLContext
            sslContext.init(null, trustManager.getTrustManagers(), null);
            LogUtils.e("携带证书发送请求");
        } catch (Exception e) {
            e.printStackTrace();
            LogUtils.e("证书解析出问题");
            Log.e("SslContextFactory-->", e.getMessage());
        }
        return sslContext.getSocketFactory();
    }

}

是的，就是这个报错：SSLHandshakeException

自此开始百度：

https://www.jianshu.com/p/64172ccfb73b

https://www.jianshu.com/p/995c0c7c8875

……

很多，但依然无效。

偶然一片博客指出retrofit 2.0以上，重写SSLContext的SSLSocketFactory  和TrustManager是无效的，

只能通过反射原理是retrofit默认信任全部证书。

至此，降低了retorfit的版本为1.9，在这个基础上使用其他常规的方法重写SSLSocketFactory就可以实现抓包时抓不到联网交互数据。

常规防范很多，retrofit 2.0版本也更新了不少东西,相比较以前更好用了很多。希望有关于retrofit2.0以上版本的cer证书配置方法更早接触…
