創建工具HttpRequestUtil類： import java.util.ArrayList; import java.util.Iterator; import java.util.List; import java.util.Map; import java.util.Map.Entry; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; public class HttpRequestUtil {@SuppressWarnings({ "rawtypes", "unchecked" })public static String doPost(String url,Map<String,String> map,String charset){ HttpClient httpClient = null; HttpPost httpPost = null; String result = null; try{ httpClient = new SSLClient(); httpPost = new HttpPost(url); //設置參數 List<NameValuePair> list = new ArrayList<NameValuePair>(); Iterator iterator = map.entrySet().iterator(); while(iterator.hasNext()){ Entry<String,String> elem = (Entry<String, String>) iterator.next(); list.add(new BasicNameValuePair(elem.getKey(),elem.getValue())); } if(list.size() > 0){ UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,charset); httpPost.setEntity(entity); } HttpResponse response = httpClient.execute(httpPost); if(response != null){ HttpEntity resEntity = response.getEntity(); if(resEntity != null){ result = EntityUtils.toString(resEntity,charset); } } }catch(Exception ex){ ex.printStackTrace(); } return result; } }

2.創建SSLClient類

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.conn.ClientConnectionManager; import org.apache.http.conn.scheme.Scheme; import org.apache.http.conn.scheme.SchemeRegistry; import org.apache.http.conn.ssl.SSLSocketFactory; import org.apache.http.impl.client.DefaultHttpClient; public class SSLClient extends DefaultHttpClient{public SSLClient() throws Exception{ super(); SSLContext ctx = SSLContext.getInstance("TLS"); X509TrustManager tm = new X509TrustManager() { @Override public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { } @Override public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { } @Override public X509Certificate[] getAcceptedIssuers() { return null; } }; ctx.init(null, new TrustManager[]{tm}, null); SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); ClientConnectionManager ccm = this.getConnectionManager(); SchemeRegistry sr = ccm.getSchemeRegistry(); sr.register(new Scheme("https", 443, ssf)); } }
3，需要的jar包文件:

commons-codec-1.6.jar

commons-logging-1.1.1.jar

fluent-hc-4.2.1.jar

httpclient-4.2.1.jar

httpclient-cache-4.2.1.jar

httpcore-4.2.1.jar

httpmime-4.2.1.jar
