JAVA利用HttpClient进行POST请求（HTTPS）

1.写一个SSLClient类，继承至HttpClient

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);  
        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);  
        ClientConnectionManager ccm = this.getConnectionManager();  
        SchemeRegistry sr = ccm.getSchemeRegistry();  
        sr.register(new Scheme("https", 543, ssf));  
    }  
}

 2.写一个利用HttpClient发送post请求的类

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

import java.util.HashMap;
import java.util.Map;
//对接口进行测试  
public class HttpsPost {
	public static void main(String[] args){
		String url = "https://localhost:8080/test.jsp";
	    String charset = "utf-8";  
	    HttpClientUtil httpClientUtil = new HttpClientUtil();  
//        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 result = httpClientUtil.doPost(httpOrgCreateTest,createMap,charset);  
        String result = httpClientUtil.doPost(url,createMap,charset);  
        System.out.println("result:"+result);  
	}
}
