【问题描述】：

我正在尝试使用 (retrofit 2.0, okhttp3) 进行 https 调用但它显示 sslSocketFactory(getSSLConfig()) 已弃用并提供其他选项
sslSocketFactory(SSLSocketFactory sslSocketFactory, X509TrustManager trustManager)
我想更新我的代码并使用新选项而不是不推荐使用的方法我在网上搜索但找不到任何好的参考。如果有人能对这个问题提供一些很好的参考将非常有帮助

Now that SSLSocketFactory is deprecated on Android, what would be the best way to handle Client Certificate Authentication?的可能重复

【解决方案1】：

您需要有效的证书。创建信任任何 ssl 证书的受信任 OkHttpClient。试试这个代码：

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));
}
X509TrustManager trustManager = (X509TrustManager) trustManagers[0];
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, new TrustManager[] { trustManager }, null);
SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
OkHttpClient client = new OkHttpClient.Builder().sslSocketFactory(sslSocketFactory, trustManager);
