最近项目中，用到了登陆后获取并携带cookies发起请求的业务场景，现总结写出来备忘一下。

1.定义存取cookies信息的全局变量

 public class HttpUtil {

     /**

      * 用来存取cookies信息的变量.

      */

     private static CookieStore cookieStore;

2.登陆后获取cookies信息存储到全局变量

 public class HttpUtil {

     /**

      *

      * @param httpUrl

      *            地址

      * @param paramMap

      *            参数

      *

      */

     public static String loginPost(String httpUrl, Map<String, Object> paramMap) throws Exception {

         if (log.isInfoEnabled()) {

             log.info("请求httpUrl=" + httpUrl);

             log.info("请求params=" + JSONObject.toJSONString(paramMap));

         }

         // 创建httpPost

         HttpPost httpPost = new HttpPost(httpUrl);

         // 设置参数

         List<NameValuePair> params = new ArrayList<>();

         if (paramMap != null && paramMap.size() > 0) {

             Set<String> keySet = paramMap.keySet();

             for (String key : keySet) {

                 params.add(new BasicNameValuePair(key, UcopCommonUtil.convertString(paramMap.get(key))));

             }

             httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

         }

         String response;

         DefaultHttpClient httpClient = null;

         try {

             httpClient = new DefaultHttpClient();

             String contentCharset = CoreProtocolPNames.HTTP_CONTENT_CHARSET;

             String soTimeOut = CoreConnectionPNames.SO_TIMEOUT;

             String connectTimeOut = CoreConnectionPNames.CONNECTION_TIMEOUT;

             httpClient.getParams().setParameter(contentCharset, "utf-8");

             httpClient.getParams().setParameter(soTimeOut, 60000);

             httpClient.getParams().setParameter(connectTimeOut, 60000);

             HttpResponse httpResponse = httpClient.execute(httpPost);

             // 获得返回结果

             response = EntityUtils.toString(httpResponse.getEntity(), UcopUtils.UCOP_DEFAULT_CHARSET);

             // 获得cookie并存取

             this.cookieStore = httpClient.getCookieStore();

             List<Cookie> cookieList = this.cookieStore.getCookies();

             for (Cookie cookie : cookieList){

                 String name =cookie.getName();

                 String value = cookie.getValue();

                 log.info("登陆成功，cookie name = " + name + ", cookie value = " + value);

             }

             if (log.isInfoEnabled()) {

                 log.info("响应内容=" + response);

             }

             return response;

         } catch (Exception e) {

             log.error("HttpPost请求失败：" + e.getMessage(), e);

             throw new RuntimeException("HttpPost请求失败：" + e.getMessage(), e);

         } finally {

             if (null != httpClient) {

                 httpClient.getConnectionManager().shutdown();

             }

         }

     }

3.携带cookie发送业务请求

 public class HttpUtil {

     /**

      *

      * @param url            请求地址

      * @param paramMap              请求内容

      * @return 响应内容

      * @throws Exception

      */

     public static String requestPostWithCookie(String url, Map<String, Object> paramMap) throws Exception {

         if (log.isInfoEnabled()) {

             log.info("post请求地址：" + url);

             log.info("post请求内容：" + paramMap);

         }

         long beginTime = System.currentTimeMillis();

         try {

             HttpClient httpClient = HttpClients.custom().setDefaultCookieStore(this.cookieStore).build();

             HttpPost httpPost = new HttpPost(url);

             // 设置参数

             List<NameValuePair> params = new ArrayList<>();

             if (paramMap != null && paramMap.size() > 0) {

                 Set<String> keySet = paramMap.keySet();

                 for (String key : keySet) {

                     params.add(new BasicNameValuePair(key, UcopCommonUtil.convertString(paramMap.get(key))));

                 }

                 httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

             }

             // 设置请求和传输超时时间

             RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(120000).setConnectTimeout(120000).build();

             httpPost.setConfig(requestConfig);

             // 发起请求

             HttpResponse response = httpClient.execute(httpPost);

             // 获取响应数据并转换成JSON

             String resString = EntityUtils.toString(response.getEntity(),  UcopUtils.UCOP_DEFAULT_CHARSET);

             log.info("post响应内容: " + resString);

             return resString;

         } catch (Exception e) {

             log.error("请求失败：" + e.getMessage(), e);

             throw e;

         } finally {

             log.info("结束post请求，耗时(ms)：" + (System.currentTimeMillis() - beginTime));

         }

     }

补充：HttpClient获取Cookie的两种方式

1.使用DefaultHttpClient类实例化httpClient对象：

 package com.zat.ucop.bus.service.impl;

 import com.alibaba.fastjson.JSONObject;

 import com.zat.ucop.service.util.UcopCommonUtil;

 import com.zat.ucop.service.util.UcopUtils;

 import org.apache.http.HttpResponse;

 import org.apache.http.NameValuePair;

 import org.apache.http.client.CookieStore;

 import org.apache.http.client.HttpClient;

 import org.apache.http.client.config.RequestConfig;

 import org.apache.http.client.entity.UrlEncodedFormEntity;

 import org.apache.http.client.methods.HttpPost;

 import org.apache.http.cookie.Cookie;

 import org.apache.http.impl.client.DefaultHttpClient;

 import org.apache.http.impl.client.HttpClients;

 import org.apache.http.message.BasicNameValuePair;

 import org.apache.http.params.CoreConnectionPNames;

 import org.apache.http.params.CoreProtocolPNames;

 import org.apache.http.util.EntityUtils;

 import org.slf4j.Logger;

 import org.slf4j.LoggerFactory;

 import java.util.ArrayList;

 import java.util.List;

 import java.util.Map;

 import java.util.Set;

 public class HttpUtil {

     private static Logger log = LoggerFactory.getLogger(HttpUtil.class);

     /**

      * 用来存取cookies信息的变量.

      */

     private static CookieStore cookieStore;

     /**

      *

      * @param httpUrl

      *            地址

      * @param paramMap

      *            参数

      *

      */

     public static String loginPost(String httpUrl, Map<String, Object> paramMap) throws Exception {

         if (log.isInfoEnabled()) {

             log.info("请求httpUrl=" + httpUrl);

             log.info("请求params=" + JSONObject.toJSONString(paramMap));

         }

         // 创建httpPost

         HttpPost httpPost = new HttpPost(httpUrl);

         // 设置参数

         List<NameValuePair> params = new ArrayList<>();

         if (paramMap != null && paramMap.size() > 0) {

             Set<String> keySet = paramMap.keySet();

             for (String key : keySet) {

                 params.add(new BasicNameValuePair(key, UcopCommonUtil.convertString(paramMap.get(key))));

             }

             httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

         }

         String response;

         DefaultHttpClient httpClient = null;

         try {

             httpClient = new DefaultHttpClient();

             String contentCharset = CoreProtocolPNames.HTTP_CONTENT_CHARSET;

             String soTimeOut = CoreConnectionPNames.SO_TIMEOUT;

             String connectTimeOut = CoreConnectionPNames.CONNECTION_TIMEOUT;

             httpClient.getParams().setParameter(contentCharset, "utf-8");

             httpClient.getParams().setParameter(soTimeOut, 60000);

             httpClient.getParams().setParameter(connectTimeOut, 60000);

             HttpResponse httpResponse = httpClient.execute(httpPost);

             // 获得返回结果

             response = EntityUtils.toString(httpResponse.getEntity(), UcopUtils.UCOP_DEFAULT_CHARSET);

             // 获得cookie并存取

 82             cookieStore = httpClient.getCookieStore();

 83             List<Cookie> cookieList = cookieStore.getCookies();

 84             for (Cookie cookie : cookieList){

 85                 String name =cookie.getName();

 86                 String value = cookie.getValue();

 87                 log.info("登陆成功，cookie name = " + name + ", cookie value = " + value);

 88             }

             if (log.isInfoEnabled()) {

                 log.info("响应内容=" + response);

             }

             return response;

         } catch (Exception e) {

             log.error("HttpPost请求失败：" + e.getMessage(), e);

             throw new RuntimeException("HttpPost请求失败：" + e.getMessage(), e);

         } finally {

                     params.add(new BasicNameValuePair(key, UcopCommonUtil.convertString(paramMap.get(key))));

                 }

                 httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));

             }

             // 设置请求和传输超时时间

             RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(120000).setConnectTimeout(120000).build();

78                 log.info("cookie name = " + name + ", cookie value = " + value);

79             }

             // 获取响应数据并转换成JSON

             String resString = EntityUtils.toString(response.getEntity(),  UcopUtils.UCOP_DEFAULT_CHARSET);
