Java发送https的post请求方法

1、Java 发送 https 的 post 请求方法import java.io.BufferedReader;import java.io.FileInputStream;import java.io.IOException;import java.io.InputStreamReader;import .MalformedURLException;import .URL;import java.security.GeneralSecurityException;import java.security.KeyStore;import .ssl.HostnameVerifier;import

2、.ssl.HttpsURLConnection;import .ssl.KeyManagerFactory;import .ssl.SSLContext;import .ssl.TrustManagerFactory;public class HttpsPost /* 获得 KeyStore.* param keyStorePath密钥库路径* param password* 密码* return 密钥库* throws Exception*/public static KeyStore getKeyStore(String password,String keyStorePath)throw

3、s Exception / 实例化密钥库KeyStore ks = KeyStore.getInstance(JKS);/ 获得密钥库文件流FileInputStream is = newFileInputStream(keyStorePath);/ 加载密钥库ks.load(is, password.toCharArray();/ 关闭密钥库文件流is.close();return ks;/*获得 SSLSocketFactory.param password密码* param keyStorePath*密钥库路径* param trustStorePath*信任库路径* return SS

4、LSocketFactory* throws Exception*/public static SSLContext getSSLContext(String password,String keyStorePath, String trustStorePath) throws Exception / 实例化密钥库KeyManagerFactory keyManagerFactory =KeyManagerFactory .getInstance(KeyManagerFactory.getDe faultAlgorithm();/ 获得密钥库KeyStore keyStore = getKey

5、Store(password, keyStorePath);/ 初始化密钥工厂keyManagerFactory.init(keyStore,password.toCharArray();/ 实例化信任库TrustManagerFactory trustManagerFactory =TrustManagerFactory .getInstance(TrustManagerFactory.getD efaultAlgorithm();/ 获得信任库KeyStore trustStore = getKeyStore(password, trustStorePath);/ 初始化信任库 trust

6、ManagerFactory.init(trustStore);/ 实例化 SSL 上下文 SSLContext ctx = SSLContext.getInstance(TLS);/ 初始化 SSL 上下文ctx.init(keyManagerFactory.getKeyManagers(),trustManagerFactory.getTrustManagers(), null);/ 获得 SSLSocketFactory return ctx;* 初始化 HttpsURLConnection.* param password* 密码* param keyStorePath*密钥库路径*

9、c void post(String httpsUrl, String xmlStr) HttpsURLConnection urlCon = null;try urlCon = (HttpsURLConnection) (newURL(httpsUrl).openConnection();urlCon.setDoInput(true);urlCon.setDoOutput(true);urlCon.setRequestMethod(POST);urlCon.setRequestProperty(Content-Length,String.valueOf(xmlStr.getBytes().l
