1 新建java类，作用是绕过证书用

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; 
        } 
    }

        //添加信任主机
