httpclient4.5擷取和設定cookie

由于用以前一寫版本的代碼擷取cookie失效後，自己查了下。應該是改過了

下面是代碼：

[java]

view plain copy

public static void main(String[] args) {
    CookieStore cookieStore = new BasicCookieStore();
    CloseableHttpClient httpClient = HttpClients.custom()
             .setDefaultCookieStore(cookieStore)
             .build();
     try {

          HttpPost post = new HttpPost("http://www.baiduc.com");
          BasicClientCookie cookie = new BasicClientCookie("name", "zhaoke"); 
          cookie.setVersion(0);  
          cookie.setDomain("/pms/");   //設定範圍
          cookie.setPath("/"); 
          cookieStore.addCookie(cookie);
          httpClient.execute(post);//
          List<Cookie> cookies = cookieStore.getCookies();
          for (int i = 0; i < cookies.size(); i++) {
              System.out.println("Local cookie: " + cookies.get(i));
          }
        } catch (Exception e) {
            e.printStackTrace();
        }finally{

        }
    }
