public class HttpRequestDemo {
	private String baseUrl;
    private HttpClient httpClient;
    
    @Before
    public void setUp() {
        baseUrl = "http://localhost:8087/???";
        httpClient = HttpClientBuilder.create().build();
    }
	
	@Test
    public void testSend() throws Exception {
        String body = JSON.toJSONString(参数);

        HttpPost req = new HttpPost(baseUrl);

        List<Header> headers = new ArrayList<Header>();
        headers.add(new BasicHeader("头部信息", 值));
        req.setHeaders(headers.toArray(new Header[0]));
        req.addHeader(HTTP.CONTENT_TYPE, "application/json");//请求参数为JSON格式

        StringEntity entity = new StringEntity(body, "UTF-8");
        req.setEntity(entity);
        
        HttpResponse resp = httpClient.execute(req);
        HttpEntity respEntity = resp.getEntity();//获得返回数据
        String text = EntityUtils.toString(respEntity, "UTF-8");
        
        JSONObject obj = (JSONObject) JSONObject.parse(text);
        assertEquals(true, obj.get("success"));
    }
