okhttp关于https的证书信任问题

亲测很管用，步骤如下：

1，新TrustAllcert类实现X509TrustManager接口：

[java]  view plain  copy

1. public class TrustAllCerts implements X509TrustManager {  
2.     @Override    
3.     public void checkClientTrusted(X509Certificate[] chain, String authType) {}  
4.     
5.     @Override    
6.     public void checkServerTrusted(X509Certificate[] chain, String authType) {}  
7.     
8.     @Override    
9.     public X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];}    
10. }    

2，方法createSSLSocketFactory()调用类TrustAllcert,获取SSLSocketFactory：

[java]  view plain  copy

1.     private static SSLSocketFactory createSSLSocketFactory() {  
2.         SSLSocketFactory ssfFactory = null;  
3.   
4.         try {  
5.             SSLContext sc = SSLContext.getInstance("TLS");  
6.             sc.init(null, new TrustManager[]{new TrustAllCerts()}, new SecureRandom());  
7.   
8.             ssfFactory = sc.getSocketFactory();  
9.         } catch (Exception e) {  
10.         }  
11.   
12.         return ssfFactory;  
13.     }  
14. }  

3，初始化OKHttpClient配置：

[java]  view plain  copy

1. OkHttpClient.Builder builder = new OkHttpClient.Builder();  
2.        builder.connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS);  
3.        builder.sslSocketFactory(createSSLSocketFactory());  
4.        builder.hostnameVerifier(new HostnameVerifier() {  
5.            @Override  
6.            public boolean verify(String hostname, SSLSession session) {  
7.                return true;  
8.            }  
9.        });  

好了，搞定了。此方法是okHttp信任所有的https。
