@Test void testPost() throws Exception { //获取httpclient对象 CloseableHttpClient httpClient = HttpClients.createDefault(); //url地址 String url = "http://localhost:8080/admin/employee/login"; //获取HttpPost对象 HttpPost httpPost = new HttpPost(url); //模拟请求体数据--数据格式为json JSONObject jsonObject = new JSONObject(); jsonObject.put("username", "admin"); jsonObject.put("password", "123456"); //设置请求体参数对象-这里HttpEntity的实现类-StringEntity StringEntity stringEntity = new StringEntity(jsonObject.toJSONString()); httpPost.setEntity(stringEntity); //设置请求编码格式 stringEntity.setContentEncoding("utf-8"); //设置请求体数据格式 stringEntity.setContentType("application/json"); //发送post请求 CloseableHttpResponse response = httpClient.execute(httpPost); //获取返回数据 int statusCode = response.getStatusLine().getStatusCode(); System.out.println("状态响应码：" + statusCode); HttpEntity entity = response.getEntity(); //将返回的实体类解析为字符串 String resultData = EntityUtils.toString(entity); System.out.println("返回数据：" + resultData); //关闭资源 response.close(); httpClient.close(); }
