java https post請求並忽略證書,參數放在body中

1 新建java類，作用是繞過證書用

package cn.smartercampus.core.util;
import java.security.cert.CertificateException;  
import java.security.cert.X509Certificate;  
  
import javax.net.ssl.X509TrustManager; 
public class MyX509TrustManager implements X509TrustManager {  
	  
    public void checkClientTrusted(X509Certificate[] chain, String authType)  
            throws CertificateException {  
    }  
  
    public void checkServerTrusted(X509Certificate[] chain, String authType)  
            throws CertificateException {  
    }  
  
    public X509Certificate[] getAcceptedIssuers() {  
        return null;  
    }  
}
