我是靠谱客的博主真实爆米花，最近开发中收集的这篇文章主要介绍JAVA利用HttpClient进行POST请求（HTTPS），觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

为了避免需要证书，所以用一个类继承DefaultHttpClient类，忽略校验过程。

1.写一个SSLClient类，继承至HttpClient

[java] 
view plain
 copy

 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;  
 //用于进行Https请求的HttpClient  
 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);  
         //允许所有证书
         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));  
     }  
 }  

2.写一个利用HttpClient发送post请求的类

[java] 
view plain
 copy

 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;  
 /* 
  * 利用HttpClient进行post请求的工具类 
  */  
 public class HttpClientUtil {  
     public 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);  
             //设置参数  
             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;  
     }  
 }  

3.调用post请求的测试代码

[java] 
view plain
 copy

 import java.util.HashMap;  
 import java.util.Map;  
 //对接口进行测试  
 public class TestMain {  
     private String url = "https://192.168.1.101/";  
     private String charset = "utf-8";  
     private HttpClientUtil httpClientUtil = null;  
       
     public TestMain(){  
         httpClientUtil = new HttpClientUtil();  
     }  
       
     public void test(){  
         String httpOrgCreateTest = url + "httpOrg/create";  
         Map<String,String> createMap = new HashMap<String,String>();  
         createMap.put("authuser","*****");  
         createMap.put("authpass","*****");  
         createMap.put("orgkey","****");  
         createMap.put("orgname","****");  
         String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,createMap,charset);  
         System.out.println("result:"+httpOrgCreateTestRtn);  
     }  
       
     public static void main(String[] args){  
         TestMain main = new TestMain();  
         main.test();  
     }  
 }
