1.升版本4.9.3以上

2、加个函数获取X509TrustManager

public static X509TrustManager getX509TrustManager() {
        X509TrustManager trustManager = null;
        try {
            TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
            trustManagerFactory.init((KeyStore) null);
            TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
            if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
                throw new IllegalStateException("Unexpected default trust managers:" + Arrays.toString(trustManagers));
            }
            trustManager = (X509TrustManager) trustManagers[0];
        } catch (Exception e) {
            e.printStackTrace();
        }

        return trustManager;
    }

3.创建的时候加上上面的X509TrustManager

 private static synchronized OkHttpClient getInstance() {
        okHttpClient = new OkHttpClient().newBuilder()
                .connectTimeout(15, TimeUnit.SECONDS)
                .readTimeout(15, TimeUnit.SECONDS)
                .writeTimeout(15, TimeUnit.SECONDS)
                .sslSocketFactory(new SSLSocketClient().getSSLSocketFactory(),SSLSocketClient.getX509TrustManager())//配置
                .hostnameVerifier(new SSLSocketClient().getHostnameVerifier())//配置
                .build();
        if (okHttpClient == null) {
            okHttpClient = new OkHttpClient();
        }
        return okHttpClient;
    }

重点是下面这句

.sslSocketFactory(new SSLSocketClient().getSSLSocketFactory(),SSLSocketClient.getX509TrustManager())
