1.加证书（这里不说）

2.修改代码

       });

       SSLContext context = null;
       if (trustManagers == null) {

       }

       try {

       } catch (KeyManagementException e) {

       }

       HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
   }

}

在调用网络前使用

FakeX509TrustManager.allowAllSSL(); //it is dangerous!但是有的时候我们需要这样做！！       //========================StringRequest=====================================================       StringRequest httpRequest = new StringRequest(requestMethod, url, new Response.Listener<String>() {           @Override           public void onResponse(String response) { 。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
