httpcomponents-client-4.3.4 HTTPS地址访问

╰半橙微兮° 2022-08-10 14:44 46阅读 0赞

基于httpcomponents-client-4.3.4进行https地址访问，在网上收集做法如下(未验证其正确性,仅供参考):  
  
1.引用httpcomponents-client-4.3.4中的相关jar包，引用org.json.jar

我猜测MySSLSocketFactory可能的实现如下:  
  
import javax.net.ssl.HostnameVerifier;  
  
import org.apache.http.conn.scheme.SocketFactory;  
import org.apache.http.conn.ssl.SSLSocketFactory;  
import org.apache.http.conn.ssl.X509HostnameVerifier;  
  
public class MySSLSocketFactory \{  
    private static SSLSocketFactory socketFactory = null;  
  
    @SuppressWarnings("deprecation")  
    public static SocketFactory getInstance() \{  
        if(null == socketFactory)\{  
            HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW\_ALL\_HOSTNAME\_VERIFIER;  
            socketFactory = SSLSocketFactory.getSocketFactory();  
            socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);  
        \}  
        return socketFactory;  
    \}  
  
\}
