Java way to post a request on the https protocol site issues

Request online to find a variety of ways https protocol , almost all the following forms:

  public class HttpsUtil{
  
  private static class TrustAnyTrustManager implements X509TrustManager {
  
  		public void checkClientTrusted(X509Certificate[] chain, String authType)
  				throws CertificateException {
  		}
  
  		public void checkServerTrusted(X509Certificate[] chain, String authType)
  				throws CertificateException {
  		}
  
  		public X509Certificate[] getAcceptedIssuers() {
  			return new X509Certificate[] {};
  		}
  }
  
  private static class TrustAnyHostnameVerifier implements HostnameVerifier {
  		public boolean verify(String hostname, SSLSession session) {
  			return true;
  		}
  }
  
  
  /**

  */
  public static byte[] post(String url, String content, String charset)
  			throws NoSuchAlgorithmException, KeyManagementException,
  			IOException {
  		SSLContext sc = SSLContext.getInstance("SSL");
  		sc.init(null, new TrustManager[] { new TrustAnyTrustManager() },
  				new java.security.SecureRandom());
  
  		URL console = new URL(url);
  		HttpsURLConnection conn = (HttpsURLConnection) console.openConnection();
  		conn.setSSLSocketFactory(sc.getSocketFactory());
  		conn.setHostnameVerifier(new TrustAnyHostnameVerifier());
  		conn.connect();
  		DataOutputStream out = new DataOutputStream(conn.getOutputStream());
  		out.write(content.getBytes(charset));
  		// 刷新、关闭
  		out.flush();
  		out.close();
  		InputStream is = conn.getInputStream();
  		if (is != null) {
  			ByteArrayOutputStream outStream = new ByteArrayOutputStream();
  			byte[] buffer = new byte[1024];
  			int len = 0;
  			while ((len = is.read(buffer)) != -1) {
  				outStream.write(buffer, 0, len);
  			}
  			is.close();
  			return outStream.toByteArray();
  		}
  		return null;
  }
  
  
  }
  

However, I used this method to access it , or not being given :
[16:38:19.303] java.lang.IllegalArgumentException: protocol = https host = null

Which god , there is wood there a good way ah.


------ Solution ------------------------------------ --------
try SSLContext sc = SSLContext.getInstance ("SSL", "SunJSSE");
------ For reference only - -------------------------------------
or not , the same error
- ----- For reference only ---------------------------------------
which line newspaper 's fault ?
------ For reference only -------------------------------------- -
reported that this line conn.connect ();
------ For reference only --------------------- ------------------
this is the wrong message
------ For reference only ----- ----------------------------------
commented conn.setHostnameVerifier (new TrustAnyHostnameVerifier ()); try
------ For reference only ------------------------------------ ---
commented , still the same error what method you use to access the https ?
------ For reference only -------------------------------------- -
requested address was wrong , https ; less behind both slash. . . Plus after it. . . Own imprudent . .
