Java中HttpPost请求流程--4.5.2版本

public class HttpTest(){    public void testHttpPost() throws Exception{        //1. 创建一个客户端(浏览器)        HttpClient httpClient = HttpClientBuilder.create().build();        //2. 初始化post请求的过程        String url = "www.baidu.com"        HttpPost post = new HttpPost("url");        //3.传递参数        List<NameValuePair> nvps = new ArrayList<NameValuePair>();          nvps.add(new BasicNameValuePair("arg0", "1"));          nvps.add(new BasicNameValuePair("arg1", "2"));          post.setEntity(new UrlEncodedFormEntity(nvps));         post.setHeader("Content-Type", "application/x-www-form-urlencoded");        //4. 用刚才创建的客户端去执行post请求        //webservice SOAP        HttpResponse response = httpClient.execute(post);        HttpEntity httpEntity = response.getEntity();        String result = EntityUtils.toString(httpEntity, "UTF-8");        //JSONObject jsonObject = JSONObject.fromObject(result);        System.out.println(result);        }    }
