maven引用：

		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.5.1</version>
		</dependency>

example:

		String resultJson = null;
		CloseableHttpClient httpclient = HttpClients.createDefault();
		String url = "http://xxxx";
		HttpPost httpPost = new HttpPost(url);
        List <NameValuePair> params = new ArrayList<NameValuePair>();  
        params.add(new BasicNameValuePair("qqq", "xx"));   
	    httpPost.setEntity(new UrlEncodedFormEntity(params,Charset.forName("UTF-8")));  
		CloseableHttpResponse response = httpclient.execute(httpPost);
		HttpEntity entity = response.getEntity();
		String entityStr = EntityUtils.toString(entity);
		JSONObject jsonObject = JSONObject.fromObject(entityStr);
