okhttp3去掉https证书校验获取数据或者加载图片

1、获取去掉https的证书校验的OkHttpClient:

1、

/**      * 获取OkHttpClient      *      * @return OkHttpClient      */     public static OkHttpClient getUnsafeOkHttpClient() {         try {             final TrustManager[] trustAllCerts = new TrustManager[]{                     new X509TrustManager() {                         @Override                         public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {                         }                         @Override                         public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {                         }                         @Override                         public java.security.cert.X509Certificate[] getAcceptedIssuers() {                             return new java.security.cert.X509Certificate[]{};                         }                     }             };             final SSLContext sslContext = SSLContext.getInstance("SSL");             sslContext.init(null, trustAllCerts, new java.security.SecureRandom());             final javax.net.ssl.SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();             OkHttpClient.Builder builder = new OkHttpClient.Builder();             builder.sslSocketFactory(sslSocketFactory);             builder.hostnameVerifier(new HostnameVerifier() {                 @Override                 public boolean verify(String hostname, SSLSession session) {                     return true;                 }             });             return builder.build();         } catch (Exception e) {             throw new RuntimeException(e);         }     }

2、其他使用就跟okhttp3使用没差别。

3、在fresco图片加载库中引入去掉okhttps证书校验的方法：在初始化fresco时，网络加载库使用okhttp3去掉证书校验即可：

 

ImagePipelineConfig.Builder builder = OkHttpImagePipelineConfigFactory .newBuilder(AppUtils.getContext(), HttpURLConnectionUtil.getUnsafeOkHttpClient()); //BitmapConfig。默认使用RGB_565。该格式对png无效 Bitmap.Config bitmapConfig = Bitmap.Config.RGB_565; builder.setBitmapsConfig(bitmapConfig); //内存控制为最大1/8 builder.setBitmapMemoryCacheParamsSupplier( new BitmapMemoryCacheParamsSupplier((ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE))); Fresco.initialize(AppUtils.getContext(), builder.build());
