摘要：添加信任所有服務端證書也可在方法中控制信任所有證書使用發(fā)送請求默認端口測試客戶端證書路徑證書密碼發(fā)送請求導入客戶端證書添加信任證書為信任所有證書創(chuàng)建上下文初始化參數(shù)為，則不上傳客戶端證書通常情況都是如此驗證系統(tǒng)默認證書導出服務端證書，

添加信任所有服務端證書也可在方法中控制

package something;

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;
/**
 * 信任所有證書
 * @author hp
 *
 */
public class AllTrustManager implements X509TrustManager {

    @Override
    public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
        // TODO Auto-generated method stub

    }

    @Override
    public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
        // TODO Auto-generated method stub

    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        // TODO Auto-generated method stub
        return null;
    }

}

使用HttpsURLConnection發(fā)送POST請求（默認443端口）
