操作方法就是使用 CookieStore , 如果服务器返回了cookie ,后面的请求会自动带上这个Cookie
String url = "http://localhost:8080/list";
// RequestConfig requestConfig = RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD).build();
// CloseableHttpClient httpClient = HttpClients.custom()
// .setDefaultRequestConfig(requestConfig)
// .setDefaultCookieStore(cookieStore).build();
// 重点就是如下这两句代码
CookieStore cookieStore = new BasicCookieStore();
Executor executor = Executor.newInstance().use(cookieStore);
List<NameValuePair> paramList = Form.form()
.add("query_hz", "q")
.build();
// 编码成GBK
UrlEncodedFormEntity gbk = new UrlEncodedFormEntity(paramList, "gbk");
Request post = Request.Post(url)
.body(gbk) ;
HttpResponse response = executor.execute(post).returnResponse();
// 如果服务器有返回cookie，这里可以取到
List<Cookie> cookies = cookieStore.getCookies();
// do something
