Java Post 请求 Map

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();    }  }
