①. SSLClient.java

package com;

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", 443, ssf));  
  }  
}

②. HttpClientUtil.java

package com;

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> createMap,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 = createMap.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. 测试类

package com;

import java.util.HashMap;
import java.util.Map;

//对接口进行测试  
public class TestMain {  
  private String url = "http://**.**.**.**/";  
  private String charset = "utf-8";  
  private HttpClientUtil httpClientUtil = null;  

  public TestMain(){  
      httpClientUtil = new HttpClientUtil();  
  }  

  public void test(){  
      String httpOrgCreateTest = url + "assessApi/getToken";  

       //获取token
      String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,createData(),charset);  
      System.out.println("result:"+httpOrgCreateTestRtn);  
  }  

  public Map<String,String>  createData() {
      Map<String,String> createMap = new HashMap<String,String>();  
      createMap.put("account","***");  
      createMap.put("password","******");  

    return createMap;
  }  



  public static void main(String[] args){  
      TestMain main = new TestMain();  
      main.test();  
  }  


}
