HttpClient Get和Post获取其他接口的数据

Get不含参数获取

	@Test

	public void doGet() throws Exception {
		// 创建httpclient对象
		CloseableHttpClient client = HttpClients.createDefault();
		// 创建get对象
		HttpGet get = new HttpGet("http://www.baidu.com");
		// 含参数
		// HttpGet get = new HttpGet("http://www.baidu.com?id=1¶m=11");
		// 执行请求
		CloseableHttpResponse response = client.execute(get);
		// 取相应结果
		HttpEntity entity = response.getEntity();
		String string = EntityUtils.toString(entity, "utf-8");
		System.out.println(string);
		// 关闭
		response.close();
		client.close();
	}
	

get含参数获取

/**
	 * 含参数的请求
	 * @throws Exception
	 */
	@Test
	public void doGetWithParam() throws Exception {
		CloseableHttpClient client = HttpClients.createDefault();
		URIBuilder uri = new URIBuilder("http://www.baidu.com/s");
		uri.addParameter("wd", "小米7");
		HttpGet get = new HttpGet(uri.build());
		CloseableHttpResponse response = client.execute(get);
		HttpEntity entity = response.getEntity();
		System.out.println(EntityUtils.toString(entity, "utf-8"));
		response.close();
		client.close();
	}

post请求

@Test
	public void doPostWith() throws Exception {
		CloseableHttpClient client = HttpClients.createDefault();
		HttpPost post = new HttpPost("http://localhost:8082/httpclient/post.html");
//		URIBuilder uri = new URIBuilder("http://www.baidu.com/s");
//		uri.addParameter("wd", "小米7");
//		HttpGet get = new HttpGet(uri.build());
		CloseableHttpResponse response = client.execute(post);
		HttpEntity entity = response.getEntity();
		System.out.println(EntityUtils.toString(entity, "utf-8"));
		response.close();
		client.close();
	}

post含参数请求

@Test
	public void doPostWithParam() throws Exception {
		CloseableHttpClient client = HttpClients.createDefault();
		HttpPost post = new HttpPost("http://localhost:8082/httpclient/post1.html");
//		URIBuilder uri = new URIBuilder("http://www.baidu.com/s");
//		uri.addParameter("wd", "小米7");
//		HttpGet get = new HttpGet(uri.build());
		List list = new ArrayList<>();
		list.add(new BasicNameValuePair("name", "收到"));
		list.add(new BasicNameValuePair("pwd", "123"));
		StringEntity entity = new UrlEncodedFormEntity(list);
		post.setEntity(entity);
		CloseableHttpResponse response = client.execute(post);
		System.out.println(EntityUtils.toString(response.getEntity(), "utf-8"));
		response.close();
		client.close();
