获取cookie后，使用cookie进行接下来的自动化操作

System.setProperty("javax.net.ssl.trustStore", certPath);

public void uploadComponent() throws Exception {

HttpClient httpclient = HttpClientBuilder.create().build();
HttpPut httpget = new HttpPut(postURI);

handleCookie(httpget);
httpget.setHeader("Content-Type", "application/json;charset=UTF-8");
httpget.setEntity(getParamaters());

HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
String html = EntityUtils.toString(entity);

System.out.println(html);

}

private void handleCookie(HttpPut httpget) throws Exception {
String cookie = new LoginUtil().getCookieString(userName, pwd);
httpget.setHeader("Cookie", cookie);
