参考文章
Android Https相关完全解析 当OkHttp遇到Https
Aandroid中https请求的单向认证和双向认证
okhttp实现https请求
以上文章都有说明单向认证和双向认证的方法
最后参考了开源项目
okhttputils
初始化okhttp时添加以下设置
addUnSafeSslSocketAndHostnameVerifier信任所有证书不做校验（大部分简单项目做法）
/**
* 通过所有https的认证。不做判断，不安全
* @param builder
* @return
*/
private static Builder addUnSafeSslSocketAndHostnameVerifier(Builder builder) {
//如果设置了sslSocketFactory却没有配置对应的hostnameVerifier，那么Https请求是无法成功的
//不设置会报：javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
HttpsSslFactroy.SSLParams sslParams = HttpsSslFactroy.getSslSocketFactory(); //获取默认的SSLParams，通过所有认证
addSSLSocketFactory(builder, sslParams.mSSLSocketFactory, sslParams.mTrustManager);
//不设置请求https会报错：javax.net.ssl.SSLPeerUnverifiedException: Hostname xxx地址的host not verified:
//设置ip授权认证：如果已经安装该证书，可以不设置，否则需要设置??????????????不设置会报错。。。待处理
HostnameVerifier hostnameVerifier = HttpsSslFactroy.getHostnameVerifierUnSafe();
return addHostnameVerifier(builder, hostnameVerifier);
}
