网上或许零零散散有解决Retrofit https的问题，现在做个总结吧
首先初始化证书，你需要一个httpsUtils,代码如下
import java.io.IOException;
import java.io.InputStream;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.CertificateFactory;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.KeyManager;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;

private static X509TrustManager chooseTrustManager(TrustManager[] trustManagers)

return null;
}
private static class MyTrustManager implements X509TrustManager

localTrustManager.checkServerTrusted(chain, authType);
}
}
@Override
public X509Certificate[] getAcceptedIssuers()
{
return new X509Certificate[0];
}
}
}
然后在你application初始化
public class AppApplication extends Application {
public static HttpUtils.SSLParams sslParams;
@Override
public void onCreate() {
super.onCreate();
sslParams = HttpUtils.getSslSocketFactory(new InputStream[]{
getResources().openRawResource(R.raw.inpet)}, null, null);
}
}
接着就是配置你请求，Retrofit 其实就是常规配置，不做讲解，主要是okhttp的配置
// 证书文件放在了res/raw/目录下
HttpUtils.SSLParams sslParams = HttpUtils.getSslSocketFactory(new InputStream[]{
context.getResources().openRawResource(R.raw.inpet)}, null, null);
// 接下来给okhttp绑定证书
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager).build();
到此就已经成功搞定了Retrofit 2.0 https的请求
可能会有小伙伴本地测试，服务器给你证书HostName不对，返回域名验证不过，报错
Android OKHttp https java.io.IOException: Hostname was not verified
别慌，现在有两种解决办法：
1.把服务器端打一顿，然后让他重新生成服务器的证书，用真实的本地域名信息
2.不理那个菜逼，自己解决，办法如下：
// 只需要在build多加一个选项，verify默认返回的是false,只要强制返回true 搞定
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager)
.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
//强行返回true，忽略HostName验证 即验证成功
return true;
}
}).build();
到此问题已完美解决！！！
