Answer 1

// 使用HttpClient发送请求、接收响应很简单，一般需要如下几步即可。// 1. 创建HttpClient对象。// 2. 创建请求方法的实例，并指定请求URL。如果需要发送GET请求，创建HttpGet对象；如果需要发送POST请求，创建HttpPost对象。// 3. 如果需要发送请求参数，可调用HttpGet、HttpPost共同的setParams(HetpParams params)方法来添加请求参数；对于HttpPost对象而言，也可调用setEntity(HttpEntity entity)方法来设置请求参数。// 4. 调用HttpClient对象的execute(HttpUriRequest request)发送请求，该方法返回一个HttpResponse。// 5. 调用HttpResponse的getAllHeaders()、getHeaders(String name)等方法可获取服务器的响应头；调用HttpResponse的getEntity()方法可获取HttpEntity对象，该对象包装了服务器的响应内容。程序可通过该对象获取服务器的响应内容。// 6. 释放连接。无论执行方法是否成功，都必须释放连接//入口函数public static void main(String[] args) throws Exception {        //cookie存储类        BasicCookieStore cookieStore = new BasicCookieStore();        //创建一个httpclient，并设置默认cookie存储cookieStore        CloseableHttpClient httpclient = HttpClients.custom()                .setDefaultCookieStore(cookieStore)                .build();        try {            //创建HttpGet对象,需要发送GET请求https://someportal/            HttpGet httpget = new HttpGet("https://someportal/");            //HttpClient对象的execute(HttpUriRequest request)发送请求            CloseableHttpResponse response1 = httpclient.execute(httpget);            //try开始，试图执行            try {                //获取服务器返回的HttpEntity对象                HttpEntity entity = response1.getEntity();                //打印返回信息，response.getStatusLine().getStatusCode()==200链接成功，==500失败。                System.out.println("Login form get: " + response1.getStatusLine());                //HttpEntity对象提供的静态帮助类,EntityUtils.consume关闭资源                EntityUtils.consume(entity);                //打印Initial set of cookies:                System.out.println("Initial set of cookies:");                //获取Cookies并循环，空的输出None，否则输出cookie                List<Cookie> cookies = cookieStore.getCookies();                if (cookies.isEmpty()) {                    System.out.println("None");                } else {                    for (int i = 0; i < cookies.size(); i++) {                        System.out.println("- " + cookies.get(i).toString());                    }                }            } finally {                //关闭                response1.close();            }            //POST请求，并设置URI和参数            HttpUriRequest login = RequestBuilder.post()                    .setUri(new URI("https://someportal/"))                    .addParameter("IDToken1", "username")                    .addParameter("IDToken2", "password")                    .build();            //执行POST请求            CloseableHttpResponse response2 = httpclient.execute(login);            try {                //获取实体对象                HttpEntity entity = response2.getEntity();                //打印服务器返回信息                System.out.println("Login form get: " + response2.getStatusLine());                //关闭流                EntityUtils.consume(entity);                //打印cookie                System.out.println("Post logon cookies:");                List<Cookie> cookies = cookieStore.getCookies();                if (cookies.isEmpty()) {                    System.out.println("None");                } else {                    for (int i = 0; i < cookies.size(); i++) {                        System.out.println("- " + cookies.get(i).toString());                    }                }            } finally {                response2.close();            }        } finally {            //关闭httpclient            httpclient.close();        }    }
