Retrofit+OKHttp忽略https证书验证

记录这个的原因，是因为很多时候，因为后台配置的证书不正确导致APP访问不到服务器数据，导致影响自身的开发进度。没几行代码，逻辑也清晰，所以下面就直接贴出工具类吧：

 package huolongluo.yeshen.byw.injection.model;

 import java.security.SecureRandom;
 import java.security.cert.X509Certificate;

 import javax.net.ssl.HostnameVerifier;
 import javax.net.ssl.SSLContext;
 import javax.net.ssl.SSLSession;
 import javax.net.ssl.SSLSocketFactory;
 import javax.net.ssl.TrustManager;
 import javax.net.ssl.X509TrustManager;

 public class SSLSocketClient
 {
     //获取这个SSLSocketFactory
     public static SSLSocketFactory getSSLSocketFactory()
     {
         try
         {
             SSLContext sslContext = SSLContext.getInstance("SSL");
             sslContext.init(null, getTrustManager(), new SecureRandom());
             return sslContext.getSocketFactory();
         }
         catch (Exception e)
         {
             throw new RuntimeException(e);
         }
     }

     //获取TrustManager
     private static TrustManager[] getTrustManager()
     {
         TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager()
         {
             @Override
             public void checkClientTrusted(X509Certificate[] chain, String authType)
             {
             }

             @Override
             public void checkServerTrusted(X509Certificate[] chain, String authType)
             {
             }

             @Override
             public X509Certificate[] getAcceptedIssuers()
             {
                 return new X509Certificate[]{};
             }
         }};
         return trustAllCerts;
     }

     //获取HostnameVerifier
     public static HostnameVerifier getHostnameVerifier()
     {
         HostnameVerifier hostnameVerifier = new HostnameVerifier()
         {
             @Override
             public boolean verify(String s, SSLSession sslSession)
             {
                 return true;
             }
         };
         return hostnameVerifier;
     }
 }

有了以上的工具类，通过OKHttpClient.Builder对象调用 “sslSocketFactory ”方法 和 “hostnameVerifier ” 方法。类似于如下：

简言之：

 builder.sslSocketFactory(SSLSocketClient.getSSLSocketFactory());
 builder.hostnameVerifier(SSLSocketClient.getHostnameVerifier());
