Remote host closed connection during handshake

悠悠 2022-12-10 05:55 181阅读 0赞

*  https通过TSLv1和TSLv1.2协议通信。
    
    jdk1.7默认是TSLv1, 可以支持TSLv1.1,TSLv1.2,
    
    jdk1.8默认是TSLv1.2
    
    假如服务器端设置是TSLv1.2，而客服端是TSLv1, 访问就会出现Remote host closed connection during handshake的错误.
    
    \*\*解决办法：\*\*强制通过TLSv1.2或TLSv1通信，前提服务端也采用相应协议。
    
     SSLContext ctx = SSLContext.getInstance(“TLSv1.2”);
    
    或者 SSLContext ctx = SSLContext.getInstance(“TLSv1”);
    
        public class SSLClient extends DefaultHttpClient { 
        		public SSLClient() throws Exception { 
        			super();
        			SSLContext ctx = SSLContext.getInstance("TLSv1.2");
        			X509TrustManager tm = new X509TrustManager() { 
        				@Override
        				public void checkClientTrusted(X509Certi<a target=_blank target="_blank" href="http://superuser.com/questions/747377/enable-tls-1-1-and-1-2-for-clients-on-java-7">http://superuser.com/questions/747377/enable-tls-1-1-and-1-2-for-clients-on-java-7</a>ficate[] chain, String authType) throws CertificateException { 
        				}
         
        				@Override
        				public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { 
        				}
         
        				@Override
        				public X509Certificate[] getAcceptedIssuers() { 
        					return null;
        				}
        			};
        			ctx.init(null, new TrustManager[] {  tm }, null);
        			org.apache.http.conn.ssl.SSLSocketFactory ssf = new org.apache.http.conn.ssl.SSLSocketFactory(ctx,
        					org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        			ClientConnectionManager ccm = this.getConnectionManager();
        			SchemeRegistry sr = ccm.getSchemeRegistry();
        			sr.register(new Scheme("https", 443, ssf));
        		}
        	}
    
    **查看当前jvm支持的通信协议：**
    
        public static void main(String[] args) throws Exception {   
        	SSLContext context = SSLContext.getInstance("TLS");  
        	context.init(null, null, null);  
         
        	SSLSocketFactory factory = (SSLSocketFactory) context.getSocketFactory();  
        	SSLSocket socket = (SSLSocket) factory.createSocket();  
         
        	String[] protocols = socket.getSupportedProtocols();  
         
        	System.out.println("Supported Protocols: " + protocols.length);  
        	for (int i = 0; i < protocols.length; i++) {   
        		System.out.println(" " + protocols[i]);  
        	}  
         
        	protocols = socket.getEnabledProtocols();  
         
        	System.out.println("Enabled Protocols: " + protocols.length);  
        	for (int i = 0; i < protocols.length; i++) {   
        		System.out.println(" " + protocols[i]);  
        	}  
          
        }
