本文介绍了一种通过自定义信任管理器来创建SSL连接的方法。该方法包括加载证书、初始化SSL上下文及设置HTTPS连接的SSL套接字工厂的过程。

ssl connection

public URLConnection createURLConnection(String ip_pageUrl){
		try{
			
			InputStream in = new FileInputStream(this.cacertsPath);
			KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
			ks.load(in, null);
			in.close();
			
			
			SSLContext sslContext = SSLContext.getInstance(this.sslProtocol);
			
			
			
			TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
			tmf.init(ks);
			
			X509TrustManager defaultTrustManager = (X509TrustManager)tmf.getTrustManagers()[0];
			

			sslContext.init(null, new TrustManager[] { defaultTrustManager }, null);
			
			SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
			
			URL url = new URL(ip_pageUrl);
			URLConnection con = url.openConnection(); // from secure site
			if (con instanceof javax.net.ssl.HttpsURLConnection) {
				((javax.net.ssl.HttpsURLConnection) con).setSSLSocketFactory(sslSocketFactory);
			}
			
			return con;

		}catch(Exception e){
			logger.error("Post Error : ", e);
		}
		
		return null;
