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);
}
}
