添加信任所有服务端证书也可在方法中控制

package something;

import java.security.cert.CertificateException;

import java.security.cert.X509Certificate;

import javax.net.ssl.X509TrustManager;

/**

* 信任所有证书

* @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发送POST请求(默认443端口)

package something;

import java.security.KeyStoreException;

import java.security.SecureRandom;

import java.security.UnrecoverableKeyException;

import java.security.cert.CertificateException;

import javax.net.ssl.HttpsURLConnection;

import javax.net.ssl.KeyManagerFactory;

import javax.net.ssl.SSLContext;

import javax.net.ssl.SSLSocketFactory;

import javax.net.ssl.TrustManager;

public class HttpsRequest {

//测试url

private final static String URL_TEST="https://www.baidu.com";

//客户端证书路径

private final static String PATH="c://xxxx";

//证书密码

private final static String psw="123456";

/**

*/

public String doPost(String agrs) throws IOException, KeyManagementException, KeyStoreException, NoSuchAlgorithmException, CertificateException, UnrecoverableKeyException{

//导入客户端证书

KeyStore ks=KeyStore.getInstance("pkcs12");

FileInputStream instream = new FileInputStream(new File(PATH));

ks.load(instream, psw.toCharArray());

KeyManagerFactory kmf=KeyManagerFactory.getInstance("SunX509");

kmf.init(ks, psw.toCharArray());

//添加信任证书

TrustManager[] tm={new AllTrustManager()};//AllTrustManager()为信任所有证书

SSLContext ctx=SSLContext.getInstance("SSL");//创建ssl上下文

//初始化 ；参数1为null，则不上传客户端证书(通常情况都是如此)；

ctx.init(kmf.getKeyManagers(), tm, new SecureRandom());

//ctx.init(kmf.getKeyManagers(), null, new SecureRandom());//验证系统默认证书

//ctx.init(kmf.getKeyManagers(), TrustManager[] tm, new SecureRandom());//导出服务端证书，然后按照keymanager一样实现trustmanager

SSLSocketFactory sf=ctx.getSocketFactory();

URL _url=new URL(URL_TEST);

HttpsURLConnection conn=(HttpsURLConnection) _url.openConnection();

conn.setRequestMethod("POST");//设定请求方法

conn.setConnectTimeout(20000);

conn.setReadTimeout(20000);
