JAVA HTTPS

因为微信需要使用到https请求，所以贴下代码：

需要引入包下载地址：点击打开链接

需要写一个类，代码如下：

package com.dc.test;import java.io.IOException;import java.net.Socket;import java.net.UnknownHostException;import java.security.KeyManagementException;import java.security.KeyStore;import java.security.KeyStoreException;import java.security.NoSuchAlgorithmException;import java.security.UnrecoverableKeyException;import java.security.cert.CertificateException;import java.security.cert.X509Certificate;import javax.net.ssl.SSLContext;import javax.net.ssl.TrustManager;import javax.net.ssl.X509TrustManager;import org.apache.http.HttpVersion;import org.apache.http.client.HttpClient;import org.apache.http.conn.ClientConnectionManager;import org.apache.http.conn.scheme.PlainSocketFactory;import org.apache.http.conn.scheme.Scheme;import org.apache.http.conn.scheme.SchemeRegistry;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpParams;import org.apache.http.params.HttpProtocolParams;public class SSLSocketFactoryEx extends org.apache.http.conn.ssl.SSLSocketFactory{  SSLContext sslContext = SSLContext.getInstance("TLS");  public SSLSocketFactoryEx(KeyStore truststore)    throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException  {    super(truststore);    TrustManager tm = new X509TrustManager()    {      public X509Certificate[] getAcceptedIssuers()      {        return null;      }      public void checkClientTrusted(X509Certificate[] chain, String authType)        throws CertificateException      {      }      public void checkServerTrusted(X509Certificate[] chain, String authType)        throws CertificateException      {      }    };    this.sslContext.init(null, new TrustManager[] { tm }, null);  }  public Socket createSocket(Socket socket, String host, int port, boolean autoClose)    throws IOException, UnknownHostException  {    return this.sslContext.getSocketFactory().createSocket(socket, host, port,       autoClose);  }  public Socket createSocket()    throws IOException  {    return this.sslContext.getSocketFactory().createSocket();  }  public static HttpClient getNewHttpClient()  {    try    {      KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());      trustStore.load(null, null);      org.apache.http.conn.ssl.SSLSocketFactory sf = new SSLSocketFactoryEx(trustStore);      sf.setHostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);      HttpParams params = new BasicHttpParams();      HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);      HttpProtocolParams.setContentCharset(params, "UTF-8");      SchemeRegistry registry = new SchemeRegistry();      registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));      registry.register(new Scheme("https", sf, 443));      ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);      return new DefaultHttpClient(ccm, params); } catch (Exception e) {    }    return new DefaultHttpClient();  }}

https代码：

/** * HTTPS GET *  * @param url */public static void httpsGet(String url) {try {HttpClient httpclient = SSLSocketFactoryEx.getNewHttpClient();HttpGet request = new HttpGet(url);HttpResponse response = httpclient.execute(request);HttpEntity entity = response.getEntity();if (entity != null) {String content = IOUtils.toString(entity.getContent(), "UTF-8");JSONObject jo = new JSONObject(content);String test = jo.getString("test"); // 使用json对象获取返回的值System.out.println(test);}} catch (Exception e) {e.printStackTrace();}}/** * HTTPS POST * @param url */public static void httpsPost(String url) {try {org.apache.http.client.HttpClient httpclient = SSLSocketFactoryEx.getNewHttpClient();HttpPost post = new HttpPost(url);// 发送的消息体是json格式的可以这样写JSONObject jsonObj = new JSONObject();jsonObj.put("component_appid", "");jsonObj.put("component_appsecret", "");jsonObj.put("component_verify_ticket", "");post.setEntity(new StringEntity(jsonObj.toString()));HttpResponse response = httpclient.execute(post);HttpEntity entity = response.getEntity();if (entity != null) {String content = IOUtils.toString(entity.getContent(), "UTF-8");System.out.println("content: " + content);JSONObject jo = new JSONObject(content); String test = jo.getString("test"); // 使用json对象获取返回的值System.out.println(test);}} catch (Exception e) {e.printStackTrace();}}
