直接上代码：如下是个依赖登录 cookie 的接口

@Test
   public void test1()throws Exception{
       String api = "/actapi_v2/mapi/member.memberBuy";
       Map<String,String> request1 = new HashMap<>();
       request1.put("account","18656560102");
       request1.put("password","w123456");
       Map<String,String> request = new HashMap<>();
       request.put("Cookie", UserInfo.Getcookie(request1));
       //上一步会打印出cookie
       String response = HttpUtils.getInstance().sendHttpRequest("POST",host+api,request);
       System.out.println("------------------------"+response);
   }

运行后的结果

得到 cookie 的方法

public static String Getcookie(Map<String,String> map) throws Exception {
      String api = "/actapi_v2/mapi/user.signIn";

      return HttpUtils.getInstance().getSessionCookie(host+api,map);

  }

getSessionCookie 方法里

public String getSessionCookie(String url,Map<String,String>maps)throws Exception{
       HttpPost httpPost = new HttpPost(url);
       List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
       for (String key : maps.keySet()) {
           nameValuePairs.add(new BasicNameValuePair(key, maps.get(key)));
       }
       httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "UTF-8"));
       CloseableHttpResponse closeableHttpResponse = httpResponse(httpPost);
       Header[] headers = closeableHttpResponse.getAllHeaders();
       StringBuilder stringBuilder = new StringBuilder();
       for (Header header:headers){
           HeaderElement[] elements = header.getElements();
           for (HeaderElement element:elements){
               if (element.getValue() != null && !element.getValue().isEmpty()){
                   stringBuilder.append(element.getName()).append("=").append(element.getValue()).append(";");
               }

           }
       }
       return new String(stringBuilder);
   }

不知道运行后为什么会打印出两次 cookie？按理应该一次都出现不了的。感觉是我的 log4j 框架问题？
